What Kind Of Vitamin B Supplements Is The Best?

    Vitamin B complex has always been one of the best-selling products in global dietary supplements market. Which vitamin B complex has the best effect? ​​Do you know what are the differences between different types? How to choose? Let our nutritionist tell you how to distinguish them. 1. The vitamin B complex emphasizes on the active form. This type of B vitamins has the best efficacy in clinical trials, and it is also the most commonly used ingredient in European and American dietary supplement brands. The active B vitamin ingredients include active B12 (methylcobalamin), active folate (methyltetrahydrofolate glucosamine salt), and vitamin B6 in the form of P5P. The active form of B vitamins have been proven to have excellent absorption rate. For example, the bioavailability of active folate is 10 times better than common folic acid in the market; meanwhile, the power of active vitamin B12 (methylcobalamin) is 3 times more efficient than vitamin B12 (cyanocobalamin). Due to the higher price, these active ingredients are rarely used by the popular brands in the market, or may be added in lesser content level to lower the cost. However, the active form of B vitamins are the most effective ingredient that has been scientifically and clinically verified. Another key point of the active B vitamins (including the essential nutrient for humans – folic acid and vitamin B12) is its most special ability – provide methyl groups. The methyl groups have a decisive effect on the human body whereas other B vitamins don't have. Whether it is synthetic or natural, regardless of the absorption rate, the inactive vitamin Bs cannot provide methyl groups. As a result, they cannot regulate physiological functions. In fact, the effect that the active B vitamins can bring to the human body has greatly surpassed ordinary people's cognition that vitamin B complex only help boost energy levels. Active vitamin B complex supplement usually contains only one active ingredient, so the manufacturing of the formulation rely on the research and development capabilities of the brand. Many of the active vitamin B complex supplements are made by microbial fermentation, by doing so, the content is purer and the concentration is higher. It can be lower doses but have better results. 2. The vitamin B complex emphasizes on extracting from natural foods, such as yeast B-complex, buckwheat B-complex, or extracted from other food sources. This type of vitamin B group comes from natural food usually has lower concentration. As a result, you may have to take more capsules per day. Moreover, due to its low concentration, the odor/taste could be lighter. However, sourced from natural food is not equal to the active form! The effectiveness of vitamin B group is mainly determined by whether the form is active or not, even if it is derived from nature, its active content is low. The absorption rate of vitamin B complex extracted from natural foods is usually better than artificial chemical synthesis B complex, but it is still not as effective as the active type. Even though the concentration is low and the form is inactive, why do a bunch of supplements choose this natural yeast type of vitamin B complex? First of all, they are in it for the sake of the low price. Secondly, it’s less troublesome. Because the B group ingredients and content contained in the yeast B group are fixed and composed, the manufacturer only needs to purchase one raw material for processing and manufacturing whereas for the general B vitamins, you need to purchase a variety of different raw materials. In addition, because of the different content level, the raw materials purchased each time may not be used up at the same time. From the standpoint of the manufacturers, all of these increase the costs. Therefore, yeast or natural type of vitamin B complex supplements have become popular in recent years. 3. The inexpensive chemical synthesis type of vitamin B complex. This type is commonly found on the supplement market. Synthetic vitamins are not ineffective, but their component forms are not active forms, so the absorption rate is not as good. Besides, the quality of the raw materials varies greatly. Sometimes the synthesized type may have a very heavy odor/taste, so many manufacturers may use tablet form to avoid the unpleasant odor and prevent from moisture. In fact, the chemically synthesized type of B vitamins is the favorite raw material type for many manufacturers, because of its high stability, resistance to discoloration, and longer expiration time, which can extend sales and reduce overall costs. Next time when you want to buy vitamin B complex products, don't choose by price. Remember to go through the details on supplement label, so that you can choose wisely, and get the most benefit.  

Is Vitamin D Supplementation Beneficial For Women During Pregnancy?

    The importance of vitamin D supplementation during pregnancy is easily overlooked. Many people think that they can get enough vitamin D from the sun; however, they often neglect the factors influencing vitamin D via sun exposure. According to the analysis of the national nutrition and health data of the Ministry of Health and Welfare by professor Mei-Xuan Li from the School of Public Health, National Defense Medical Center, up to 98% of people have insufficient vitamin D concentration in the blood (the standard is 33μg/mL). The lowest vitamin D concentration was discovered among the age 19-44 group. The main reason is possibly due to the lack of the correct knowledge regarding vitamin D. The role of vitamin D in pregnancy is even more important, because the vitamin D level in mom-to-be would affect the vitamin D content of the fetus. Many studies have confirmed that vitamin D has different effects on women who are trying to conceive, in pregnancy and lactation. In 2009, an Australian study indicated that mothers with vitamin D deficiency had an average birth weight reduction of 200 grams in their neonates. Researches in the Netherlands also revealed that insufficient prenatal levels of vitamin D increases the risk of fetal underweight by 2.4 times. The importance of vitamin D in maternal and child health has been confirmed by more and more clinical studies. In addition, studies have found that the weight of pregnant women is very likely linked to the vitamin D deficiency. In another word, pregnancy overweight is related to low vitamin D content in the body. Compared with lean pregnant women (BMI < 25) – 36% of them lack of vitamin D, 61% of obese mothers (BMI > 30) suffer from a severe deficiency of prenatal levels of vitamin D. How much vitamin D should a pregnant woman take? It's generally recommended to take at least 400 to 600 IU of vitamin D3 daily. American Association of Clinical Endocrinology suggests to take 1500-2000 IU daily. If the pregnant woman is severely deficient, a higher dose should be supplemented under medical supervision. As for what is the safe dose range? A clinical study published in the journal “J Bone Miner Res” in 2011 indicated that a daily supplement of 4000 IU units of vitamin D3 is safe for pregnant women without side effects and can effectively increase vitamin D content in the body. The results from many other clinical trials also suggested that 2000-4000 IU per day for pregnant women is safe (Hollis BW, 2011; Hollis BW, 2013; Dawodu A, 2013; Grant CC, 2014). As for the Tolerable Upper Intake Level, the US National Institutes of Medicine (IOM) recommends an upper limit of 4000 IU per day.    

孕婦應該補充維生素 D3 嗎?

    維生素 D3 對於孕婦的重要性很容易被忽略,特別是許多人覺得日曬就可以獲得足夠的維生素 D,卻輕忽從日曬獲得維生素 D 的影響因素很多,反而不容易經由日曬獲得足夠的維生素 D 含量。據國防醫學院公共衛生學系李美璇教授分析衛福部國民營養健康資料發現,高達 98% 的人,血液中維生素 D 濃度不足(標準是 33μg/mL),尤以 19~44 歲年齡層濃度最低,主要是因為對維生素 D 的認知不足。 對於孕婦部分,維生素 D 更為重要,因為孕媽咪體內的維生素 D 也會影響到胎兒的含量,許多研究都證實維生素 D 對於備孕、孕期、及哺乳的女性各有不同的影響。在 2009 年澳洲的一項研究發現,維生素 D 缺乏的母親,其新生兒體重平均會降低 200 公克。在荷蘭的研究也發現,母親維生素 D 不足,胎兒體重不足的風險機率增加 2.4 倍,其他還有更多的臨床研究證實維生素 D 對於孕媽咪的重要性。 此外,研究發現孕媽咪的體重與肥胖程度也與維生素 D 是否缺乏有關連性。孕婦孕期間肥胖與體內維生素 D 含量過低有關,61% 的肥胖女性 (BMI>30) 其孕前的維生素 D 嚴重缺乏,而 BMI 小於 25 的女性相比,只有 36%。 至於孕媽咪應該補充多少維生素 D,一般每日建議至少 400 到 600 IU 的維生素 D3;美國內分泌醫學會則建議每日補充 1500-2000 IU。若孕媽咪嚴重缺乏,則應在醫事人員的監督與建議下補充較高劑量。至於多少是安全的範圍? 在一項 2011 年發表於期刊 J Bone Miner Res 的臨床研究證實,每日補充 4000 IU 單位的維生素 D3,對於孕婦是安全無副作用的,並且能有效的提高體內維生素 D 含量。其他多篇臨床研究的結果也建議孕婦每日 2000-4000 IU 是安全的 (Hollis BW, 2011; Hollis BW, 2013; Dawodu A, 2013; Grant CC, 2014)。至於每日食用上限,美國國家醫學院 (IOM) 建議上限值為每日 4000 IU。    

那種 B 群最有效? 營養師教你如何正確挑選 B 群

    維生素 B 群一直是市場的熱銷產品之一,但市售 B 群哪一種效果最好? 你知道各種不同形式差異在哪? 該怎麼挑選? 讓營養師來告訴你如何分辨。 1. 強調活性形式的 B 群。此種 B 群是在臨床研究上最有效的,也是歐美醫療通路品牌最常使用的成分。活性成分的 B 群例如所謂的活性 B12 (甲鈷胺)、活性葉酸(甲基四氫葉酸葡萄糖胺鹽)、或 P5P形式的維生素 B6 等。活性的維生素 B 群在研究上已經證實有著絕佳的吸收率,例如活性葉酸生物利用率是一般市售葉酸的 10 倍;活性維生素 B12 其成效也是一般市售維生素 B12 (氰鈷胺)的 3 倍。但由於其價格昂貴,所以市售品牌較少使用,或可能添加量較少。但活性形式的維生素 B 群是食用上經過科學研究與臨床驗證的最有效成分。 此外,活性 B 群的另一個重點,包括對人體最重要的葉酸與維生素 B12,其最特殊的能力是能提供甲基 (methyl group),甲基對於人體具有決定性的功效,這也是其他 B 群所無法提供的功能,無論是合成或是天然,無論吸收率多少,因為非活性 B 群本身就沒有帶有甲基,因此無法特定的調節生理機能。所以活性 B 群所能帶給人體的效用,已經大幅超越一般人對於只能幫助精神旺盛的認知。 活性維生素 B 群的原料通常是單方成分為主,所以在配方的製造與含量搭配上,就仰賴品牌商的研發能力。而活性的維生素 B 群許多是由微生物發酵所製成,所以含量較純,濃度較高,在食用也能滿足更少的食用顆數,但卻能帶來更好的效果。 2. 強調天然食物萃取的維生素 B 群,例如酵母 B 群、蕎麥 B 群、或是從其他食物中萃取的 B 群來源。這類 B 群通常在市面上販售主打就是天然,通常天然食物萃取的B群濃度低,因此可能要吃較為多顆,此外由於其濃度低,所以相對的 B 群味道較淡,但要注意的是天然食物萃取並不等於活性形式! B 群的效能主要決定在形式是否為活性,即使是天然萃取的 B 群,其所含的活性形式成分仍相當低。天然食物萃取的維生素 B 群吸收率通常已經較人工化學合成 B 群來的佳,但仍然不及活性形式 B 群來的效果好。 但濃度低,又非活性形式,為什麼市售一堆產品都要出天然酵母 B 群等產品? 主要是因為價格便宜,此外,可以省卻品牌商的麻煩。因為酵母 B 群內含的 B 群成分與含量是固定的,也已經搭配好,所以廠商只需要購買一種原料,即可加工製造。跟一般 B 群相比,需要採購多種不同原料,此外由於用量不同,每次採購的不同原料不一定能當次用完,對於品牌商而言,都是成本,所以酵母或食物萃取 B 群,成為這幾年的熱門產品,也是因為省卻了品牌商的麻煩。 3. 廉價的人工化學合成 B 群。這也是市售許多品牌所使用的維生素。人工合成的維生素並非沒有效用,只是其成分形式並非活性的形式,所以吸收率較差,此外,其原料好壞差異甚大,有時可能有著非常重的 B 群臭味,因此許多廠商可能用打錠的方式,並加上膜衣,除了可避免過重的臭味散發,也可以避免受潮。此外,化學合成的 B 群由於其穩定性高、不易變色、保存期限長可拉長販售時間,所以也是許多廠商愛用的原料,因為可以相對降低成本。 下次挑選 B 群時,別在單以價格去區分,記得多看產品上的標示,才能夠聰明挑選 B 群,食用有效益。  

The Key Factor Affects Supplements Efficacy

    Natural food or nutrients extracted from natural sources have been the popular keywords in search engines in recent years. There have been many dietary supplements indicated their ingredients coming from natural sources, including natural yeast B group, etc. It seems that as long as the word "natural" is marked, consumers will trust and buy. However, the effectiveness of a supplement is not only decided by the naturalness and purity, the key factor affects the efficacy is actually the structural form. Unfortunately, the information regarding the structural form is unable to be presented fully in Chinese, which makes it difficult for consumers to make smart choice when it comes to pick up right supplements. Why does structural form matter most? Here are a few clinical evidences would help you understand : 1. The active form of folic acid, also known as (6S)-5-methyltetrahydrofolate glucosamine salt, is 10 times higher absorption rate than ordinary folic acid. On the supplemental markets, “folic acid” is the most used form. Even the ones derived from natural yeast are also the general folic acid, which contains only a small amount of active folic acid. 2. The fish oil exists in natural fish meat is in the form of TG; however, TG form must be converted into EE form during concentration process. Many fish oil supplements are presented with EE form. In fact, the best concentrated fish oil must go through the process of re-esterification, by which it returns to TG form. This kind of concentrated fish oil is called re-esterified triglyceride (rTG). In many studies, the fish oil of rTG form has been proven that its effect is higher than the concentrated EE form. A study in September 2010 confirmed that the rTG concentrated omega-3 fish oil has the highest bioavailability, 124% higher than the general natural fish oil (non-concentrated TG form), while EE form fish oil has only 73% efficacy! 3. Vitamin E is a common ingredient in multivitamin, but it is also divided into natural and synthetic form. Natural vitamin E is generally labelled d-alpha tocopherol, its common extract source is soybeans. On the other hand, the synthetic vitamin E is labeled as dl-alpha-tocopherol. The difference between the two forms is obvious in English, but not in Chinese (in which collectively referred to as vitamin E). However, due to the difference in its structure, the efficacy of synthetic vitamin E is only about 12% of natural vitamin E. 4. Compare the vitamin D2 from natural foods (generally sourced from mushrooms) with the vitamin D3 from natural foods (generally sourced from lanolin), vitamin D3 has also been proven to be more effective than vitamin D2 in many studies. 5. Vitamin K, which is common seen in calcium supplements, also comes in different forms. Vitamin K2 is considered better than vitamin K1. In fact, vitamin K2 is divided into the form of MK-4 and MK-7, and MK-7 has been proven to be more effective than MK-4 and Vitamin K1 by clinical studies. 6. Vitamin B12 is a common ingredient in B-Complex products, the Methylcobalamin form has a higher bioavailability and utilization in human than the Cyanocobalamin form. Methylcobalamin can remains in the body for a longer period of time and at higher levels than Cyanocobalamin. Even the vitamin B12 in natural yeast B group uses the form of cyanocobalamin. The price between the two raw materials is 130 times difference. Methylcobalamin is measured in grams and is priced in ten thousand NT dollars per gram, while cyanocobalamin is about 2000-3000 NT dollars per kilogram. Although the active form is expensive, it’s the guarantee of the efficacy. The similar examples listed above are too many to mention. Basically, the lower the cost of the ingredients, the lower the price of the products, which is the reason the price difference of dietary supplements ranging from hundreds to thousands of NT dollars on the market. However, the effectiveness is relatively obvious. The truth is even the ingredients come from natural sources, the efficacy may not be the optimal. Therefore, focusing on the essence of nutrient – its structural form can ensure the best results. That is the mainstream in terms of choosing supplementation. Next time, when you are up to buying some nutritional products, in addition to get product recommendations/reviews online or by some advertisements, please remember to look closely the forms of ingredients of the supplements you want to buy. By doing so, you can buy with a peace of mind and then really benefit from the products. For the sake of health, it is important to spend money wisely on the effective products. No matter how cheaper the product is, if it has low potency, it doesn’t worth it at all.    


    天然食物或萃取自天然來源的營養素,是這幾年熱門的關鍵字。市面上一窩蜂的出現號稱天然來源的營養品,包括天然酵母 B 群等,似乎只要打上天然兩字,消費者就會買單,但其實營養品的成效好壞,除了天然與純度等因素之外,最具有決定性的影響是其成分的結構形式,而這形式在一般中文上部分資訊並無法完整呈現,也導致消費者無法清楚選擇。 為什麼我們說 "形式" 是影響一個保健營養品最具有決定性的因素? 舉幾項臨床實證,你就會明瞭 : 1. 活性形式的葉酸,又稱為 (6S)-5-甲基四氫葉酸葡萄糖胺鹽 [(6s)-5-Methyltetrahydrofolic Acid Glucosamine Salt],與一般的葉酸 (Folic Acid) 相比較,身體利用率高出十倍。一般葉酸 (Folic Acid) 就是市面上絕大多數營養品的形式,即使是天然酵母來源的葉酸,也幾乎都是一般葉酸 (Folic Acid),只含有很微量的活性葉酸。 2. 魚油,天然魚肉中的魚油是 TG 形式,但要經過濃縮,必須轉變為 EE 形式,不少濃縮魚油商會直接以此形式販售,但最好的濃縮魚油,則必須再經過重新酯化的過程,將其重新變回 TG 形式,而此種濃縮魚油又稱為 rTG 形式魚油,rTG 的魚油在許多的研究中也證實其效果比濃縮EE形式魚油來的更高。在 2010 年 9 月份的研究證實,重新酯化型三酸甘油酯(rTG)型式的濃縮 omega-3 魚油的生物利用率最高,比一般天然魚油 (非濃縮 TG 形式) 高出 124%,而 EE 型式 (濃縮 EE 形式魚油) 只有 73% 的效力! 3. 維生素 E 是綜合維他命中常見的成分,但其同樣有分天然與合成形式,天然的維生素 E 是 d-form (d-alpha-tocopherol),常見萃取來源為大豆,人工合成的維生素 E 則是 dl- form (dl-alpha-tocopherol),在英文上可以看出明顯差異,但中文則沒有區分,統稱為維生素 E。但由於其結構上的差異,人工合成維生素E其效力大概只有天然的維生素E12% 左右。 4. 同樣來自天然食物的維生素 D2 (一般來源為蘑菇),以及同樣來自天然的維生素 D3 (一般來源為羊毛脂),維生素 D3 在許多研究也證實效果比維生素 D2 更好。 5. 鈣質產品中常見的維生素 K,有不同的形式來源。維生素 K2 比維生素 K1 好。而維生素 K2 又分為 MK-4 和 MK-7 形式,而 MK-7 在臨床研究上證實效果比 MK-4 和維生素 K1 都要來的好得多。 6. B 群成分中常見的維生素 B12,甲鈷胺形式 (Methylcobalamin) 比氰鈷胺 (Cyanocobalamin) 形式人體利用率更高,氰鈷胺食用後的流失速度也更快,但即使天然酵母 B 群也幾乎都是氰鈷胺形式的維生素 B12,兩者在原料上的差異價格差了 130 倍,甲鈷胺是用公克為單位,以萬元計價,氰鈷胺則是一公斤 2000-3000 元左右,活性形式的成分雖然貴,但才是食用後成效的保證。 這些例子不勝枚舉,但基本上效力越差的原料,其成本非常低廉,這也為什麼市面上你可以看到營養品價差從數百元到數千元都有,但食用後的成效相對的差異也很明顯。即使打著天然來源的營養品,其效果也不一定是最佳的,所以購買營養品還是回歸到營養素的本質,也就是其結構形式,才能夠確保食用後的成效,這也是國外營養品的趨勢主流。 下次當您購買營養品時,除了看五花八門的網路行銷與推薦文外,記得多回頭研究一下您購買的營養品形式,當個聰明的消費者,才能買得安心,食用有成效。為了身體健康,花錢購買營養品,選擇有效的成分才是重點;若是效能低落的營養品,無論價格多便宜,其實都是太貴。  

What's UC-II/UC2? Is It Better Than Glucosamine + Chondroitin?

      What is UC-II/UC2?How Much Should You Take Per Day? What Is The Effect of UC-II/UC2? Who Need To Take UC-II/UC2? The Ideal Time of The Day To Take UC-II/UC2? The Four Tips To Select UC-II/UC2     What is UC-II/UC2?How Much Should You Take Per Day? The traditional notion of taking glucosamine and chondroitin supplements has been questioned by some clinical studies because the effect is not obvious. Among the latest formulas for the maintenance regarding our flexibility and movement, UC-II/UC2 (Undenatured Collagen Type II) is a frequently used supplement ingredient. UC2/UC-II (Undenatured Collagen Type II) refers to "Undenatured Collagen Type II". It is mainly extracted from chicken breast cartilage at low temperature and has high safety. In recent years, it has been commonly used for supporting the maintenance of body flexibility and movement. Due to the low temperature manufacturing processes, UC2/UC-II can retain the original three-strand spiral structure. To achieve significant results, 1500 mg/day of glucosamine + 1200 mg/day of chondroitin is required by clinical trial whereas a small daily dose of 40 mg on an empty stomach is what needed if you use UC-II. This is a sufficient dose suggested by the original factory and academic publications, which has been proven for the best results. Before you purchase, you should pay attention to check if the original authorized LOGO of UC2/UC-II is provided on the label, to make sure the source of the raw material. What Is The Effect of UC-II/UC2? The raw material of UC2/UC-II comes from Lonza, a major American manufacturer. Taking UC-II/UC2 could help regulate the function of specific parts in our body. There are a large number of clinical research data could support and prove that after taking UC2/UC-II supplements, the results regarding mobility, flexibility, comfort and other functions are more effective than "glucosamine + chondroitin". Besides, no serious side effects have been found. Therefore, UC-II/UC2 has been recommended by many medical professionals and professional health care personnel. Who Need To Take UC-II/UC2? 1. Elders 2. Sports lovers or athletes 3. People who work long hours 4. People who like climbing or walking The Ideal Time of The Day To Take UC-II/UC2? It is recommended to take UC-II/UC2 supplements on an empty stomach, between meals or before going to bed. The low amount of gastric acid during fasting can reduce the possibility of destroying the structure of UC-II/UC2 to ensure the effect after consumption. The Four Tips To Select UC-II/UC2: 1. Check if the original authorized LOGO of UC2/UC-II is provided on the packaging of the supplement. 2. Supplement 40mg UC-II / UC2 daily. Sufficient dose is required to see the results. 3. Pair with other ingredients to have better efficacy. 4. Choose capsule form, which is convenient and easy to swallow. Plus, the transparent capsule is the best. Avoid to take colored/white pigments, which will burden the body. The white capsule shell uses titanium dioxide as a colorant; however, studies have linked titanium dioxide to cancer risk. France has taken the lead in the EU to ban titanium dioxide as an additive in food since 2020. Moreover, capsule can eliminate the adhesive and film coating used on the tablet.

備孕期 And, after boasting this way of my tolerance, I come to the admission that it has a limit. Conduct may be founded on the hard rock or the wet marshes, but after a certain point I don't care what it's founded on. When I came back from the East last autumn I felt that I wanted the world to be in uniform and at a sort of moral attention forever; I wanted no more riotous excursions with privileged glimpses into the human heart. Only Gatsby, the man who gives his name to this book, was exempt from my reaction-Gatsby, who represented everything for which I have an unaffected scorn. If personality is an unbroken series of successful gestures, then there was something gorgeous about him, some heightened sensitivity to the promises of life, as if he were related to one of those intricate machines that register earthquakes ten thousand miles away. This responsiveness had nothing to do with that flabby impressionability which is dignified under the name of the "creative temperament"-it was an extraordinary gift for hope, a romantic readiness such as I have never found in any other person and which it is not likely I shall ever find again. No-Gatsby turned out all right at the end; it is what preyed on Gatsby, what foul dust floated in the wake of his dreams that temporarily closed out my interest in the abortive sorrows and short-winded elations of men. 備孕期 HTML link code generator And, after boasting this way of my tolerance, I come to the admission that it has a limit.

The Pregnancy Vitamins and Nutrients Advice from Nutritionist of Obstetrics & Gynecology

    In addition to a healthy diet during pregnancy, many pregnant women are curious about how to supplement their nutrition during pregnancy, because vitamins and minerals play a key role in maternal and fetal growth. Most moms-to-be care about their dietary intake. However, do you understand the nutritional needs at different stages of pregnancy? The Pregnancy Vitamins and Nutrients Advice :   Trying To Conceive Period: The most important nutrient for women who are trying to conceive is folate. The recommended daily intake of folate is 600-800 μg. Some people have a genetic mutation that hinders their body from properly and efficiently converting supplemental folic acid (a synthetic version of folate) to its usable form. Therefore, an activated form of folate is the best choice at this stage. Studies have confirmed that the absorption rate of active folate is 98% higher than the synthetic folic acid. For the same intake of folate, the efficiency of active folate is much better. The key points for pregnant women to choose folate : ❯ Choose the active coenzyme form of folate (Methyltetrahydrofolate Glucosamine Salt). Differed from artificially synthesized folic acid, the active coenzyme form of folate can be used directly in the body. ❯ Choose the easy-to-swallow capsule form, which is more natural and no additives. ❯ The recommended daily amount of folate for women who are planning pregnancy is 600-800 μg a day, and should not exceed the upper limit of 1,000 μg. First Trimester : The first trimester is when the mom-to-be enters the first stage of welcoming a new life. It’s a very important time for the development of the fetus. During these first few months of pregnancy, your body would go through a lot of changes and might feel uncomfortable. Taking right dietary supplements could effectively help moms-to-be to pass the difficult period of time. In the first trimester, in addition to supplement folate, vitamin B-complex is also recommended by American Pregnancy Association. Here are some tips for selecting vitamin B-complex : The key points for pregnant women to choose vitamin B-complex : ❯ Choose the vitamin B-complex contains active folate, which can support the healthy development and growth of fetus. ❯ Choose the vitamin B-complex contains vitamin B12 (Methylcobalamin) in the form of an active coenzyme, which can improve the health of the nervous system. ❯ Choose the vitamin B-complex includes a higher amount of vitamin B6, which can help pregnant women to get through the tough stage of the first trimester better. American Pregnancy Association recommends to supplement 25-50 mg of vitamin B6 daily. As for the upper limit of vitamin B6, do not exceed 100 mg per day. ❯ Choose the vitamin B-complex includes Choline. Choline has been confirmed by many researches that plays an essential role in supporting the development of fetus. Choline exists in many foods, but studies have found that the daily supplement of it is still not enough via diet. Thus, moms-to-be can take a choline supplement alone, or choose the vitamin B-complex containing choline, which should be more convenient. Normally during the first trimester, iron supplementation is not recommended. Because iron might worsen the symptoms of discomfortness to some pregnant women. You can have iron-rich diet instead, including red meat such as beef, lamb or spinach. Unless you don’t like to eat meat, especially if you don’t eat red meat at all, it is suggested to take iron supplement in an appropriate amount. Second Trimester : At the beginning of the second trimester, the fetus begins to grow up, and the weight of the mom-to-be starts to rise slowly at the same time. It is recommended to increase the weight by 5 kg during the second trimester. During this trimester, in addition to continuing to supplement the vitamin B group, calcium and vitamin D3 should be added as well. Many pregnant women may suffer from gastrointestinal discomfort; in this case, some of them may easily have gas or other conditions if calcium carbonate are taken. Hence, calcium carbonate is generally not recommended. Although seaweed calcium is from natural source, it is also the same form as calcium carbonate. Pregnant women should choose according to their personal conditions. The calcium intake is recommended to be more than 1000 mg per day. However, we recommend that only 2/3 of your calcium supplementation is supplemented by dietary supplements (approximately 600 mg). And the other 1/3 should be taken via food sources, including 1-2 cups of milk daily or eat foods rich in calcium, such as cheese, tofu or dried fish. Moreover, it should be paid attention that calcium intake should not exceed 500 mg at one time. When it exceeds 500 mg, the absorption rate will be reduced. In short, calcium is best absorbed when it’s taken in smaller doses; it’s better to split it into two or more doses over the day. The key points for pregnant women to choose calcium : ❯ Choose New Zealand bovine bone calcium. The form of bovine bone calcium is the same as the structure of human bones; as a result, the absorption rate is better. Bovine bone calcium also contains type 1 collagen, various minerals, bone protein and growth factors. Proven by clinical studies, it is the optimal calcium choice with best efficacy. ❯ A good calcium supplement should contain the ingredients of vitamin D3 and K2. Vitamin K2 can promote bone calcification. The key of selecting K2 is to choose the MK-7 form of vitamin K2 instead of vitamin K1, because vitamin K1 is less effective. As for the content of vitamin K2, by Dietary Reference Intakes announced by Health Promotion Administration, it is recommended that women and pregnant women should take at least 90 μg per day. As for the beginning of the second trimester, vitamin D3 is also recommended to supplement daily. It is recommended to supplement 600 IU daily. In addition to helping calcium absorption, vitamin D3 also has many effects on pregnant women. Therefore, some experts or doctors even suggest mom-to-be who is at risk of vitamin D3 deficiency can supplement 1000-2000 IU a day. However, it’s better to consult professional medical professionals beforehand. According to the information from American Pregnancy Association and the National Institutes of Health (NIH), the daily nutrient upper limit (UL) of vitamin D is recommended to be relatively safe within 4000 IU daily. Third Trimester : In addition to calcium, the most important nutrient added during the third trimester is iron. Iron plays very important role in the third trimester and breastfeeding period. Therefore, the recommended intake will be higher than that in the first and second trimesters. Studies have shown that iron supplementation during the second and third trimesters of pregnant women is often overlooked. The Dietary Nutrient Reference Intakes (DRIs) in China suggest that 45 mg of iron should be supplemented a day during the third trimester and lactation. However, regarding iron supplementation, its form and intake amount at a time will have a great impact. If a high dose is taken at one time, it may cause conditions such as gastrointestinal discomfort, and can also lead to a lower absorption rate. In terms of the form of the iron, Ferrous Bisglycinate is often recommends. Ferrous Bisglycinate is an amino acid chelate iron, especially the US Albion® patented Ferrochel® is considered as the best source of raw materials for iron supplement. Its effect is better than the general ferrous fumarate and ferrous citrate; it will not cause constipation. The key points for pregnant women to choose iron : ❯ Ferrous Bisglycinate is the top choice because it is less likely to cause constipation and other conditions. ❯ The recommendation of iron supplement is low-dose at a time and divide into several times a day, 15 mg of Ferrous Bisglycinate at one time, plus a day can be supplemented with iron of about 30-45 mg. You could adjust according to individual conditions, or suggestion from your obstetricians or medical professionals. ❯ The optimal formulation of iron is recommended to also contain ingredients of vitamin C, B6, folate and vitamin B12. Vitamin C can promote iron absorption. Meanwhile, it is advised to contain vitamin B12 and folate to help the formation of red blood cells. Moreover, vitamin B6 can contribute to the formation of porphyrin in red blood cells and helps red blood cells to maintain healthy form. Including these ingredients in the iron formula can enhance the efficacy greatly. In terms of Omega-3, it is advised to supplement throughout the whole pregnancy. As for the choice of Omega-3, it is recommended to take the kind contains more than 200-300 mg of DHA and also a small amount of EPA daily. Many doctors and experts have confirmed EPA is a safe ingredient for pregnant women; EPA is especially important for older pregnant women. EPA can support the delivery and absorption of DHA. However, it is generally not recommended to consume fish oil with too high EPA content. It’s better to control within 200 mg per day. All in all, DHA is the main focus regarding Omega-3 supplementation in pregnancy. During the lactation period, postpartum moms must continue to pay attention to the supplementation of calcium, iron, and fish oil. The supplement of vitamin B complex can enrich nutrients in breast milk. Moreover, taking care of newborns is not an easy task, vitamin B-complex can help strengthen the physical strength, energy and nutrition after childbirth. Lecithin is also an ingredient that many women use to supplement in postpartum period. Although there is no direct clinical evidence to prove that it is helpful, many new moms do feel its effect. A small amount of 1000 mg lecithin can be supplemented daily during the third trimester and 3000 mg daily after delivery. However, lecithin is a selective nutrient. If you feel like to take or wonder how much to take, it is recommended that you consult your obstetrician, gynecologist, nutritionist, medical professionals or pharmacists. By the way, one of the most important nutrient supplements for infants and young children is vitamin D3. Both Taiwan and the American Academy of Pediatrics recommend that breastfed babies or the babies mixing formula with breast milk are suggested to supplement vitamin D3 400 IU daily to help developmental needs. As for the daily upper limit of vitamin D supplementation for infants and young children, it is recommended not to exceed 1000 IU a day.
