To supplement iron more effectively requires the group power. The combined formulation could double the efficacy of the main ingredient; it is beneficial to busy modern people. For iron, its best teammates include vitamin B6, vitamin B12, folate and vitamin C. These ingredients truly complement each other, improving the absorption.

FERROPRO is a highly efficient iron supplement; it is manufactured with the finest raw materials which are carefully selected by realpromise. FERROPRO is also perfect for vegetarians. The main ingredient is sourced from US Albion® Ferrochel® (Ferrous Bisglycinate Chelate) – an innovative patented Amino Acid chelate technology (U.S. Patent 6518240). The patented TRAACS (U.S. Patent 7144737) identification process ensures the quality of Ferrochel®; it is stable, safe, and highly absorbable in addition to good bioavailability and no side effects. The excellent nutritional efficiency of Ferrochel® has been proven by more than 20 published clinical studies in the U.S., and it is widely trusted and recommended by physicians and healthcare practitioners.

In order to improve the potency, activity, stability, solubility and bioavailability to the next level, realpromise added the patented active form of Folate – Quatrefolic® into FERROPRO. Quatrefolic® is a natural reduced folate, it has been shown higher bioavailability compared to 5-MTHF calcium salt and synthetic folic acid. Meanwhile, Quatrefolic® is 100 times more soluble in water than 5-MTHF calcium salt and its absorption rate is 10 times higher than the general synthetic folic acid. Quatrefolic® is the fourth generation folate, which has long lasting stability, super high water solubility, enhanced bioavailability as well as good safety. Folate is an indispensable nutrient in the body, which works closely with vitamin B12 in making red blood cells and helps iron function properly in the body.

FERROPRO also includes the high-efficiency, high-absorbency top-grade vitamin B12 – Methylcobalamin. Cyanocobalamin is the most commonly used form of vitamin B12, it is stable and cheap; however, it is a synthetic form of vitamin B12 that is not found in natural food. Unlike Cyanocobalamin, Methylcobalamin is the most bio-available form of Vitamin B12. It is a naturally occurring form of vitamin B12. Further researches have shown Methylcobalamin remains in the body for a longer period of time and at higher levels than Cyanocobalamin, which means that your body is supplied with vitamin B12 for longer if you use Methylcobalamin. Some studies comparing the two forms reported that about 3 times as much Cyanocobalamin was excreted through urine, indicating that Methylcobalamin is retained better within human body. Vitamin B12 could benefit your body in many ways, such as supporting the normal function of your nerve cells and promoting metabolism and energy.

Another important ingredient in FERROPRO is vitamin C. It has been well documented that vitamin C can assist with iron absorption and utilization; it also plays an essential role in collagen synthesis and antioxidant protection.


FERROPRO's main ingredient is sourced from US Albion® Ferrochel® (Ferrous Bisglycinate Chelate) , which has multiple patent certifications (US patent US 6518240, US patent US 7144737, US patent US 6716814, US patent US 7838042). Ferrochel® is proven to be 3.7 ~ 6 times better than the ordinary iron supplements on the market, and it has an extra advantage of preventing the discomfort that may occur after the general iron supplements are consumed.


Quality-wise, FERROPRO chose ultra-pure plant-based capsule form instead of the common tablet form. Tablets are known to have more shelf life and also retain its potential for a longer period than the capsules due to the film coatings. However, the materials used for the coatings often include some chemical additives, such as Titanium Dioxide and Talcum powder, which are potentially hazardous to human health. Besides, the design of micro capsules is meant to reduce any discomfort while swallowing, and is more suitable for Asian women's need.


Iron is one of the most important mineral nutrients and has multiple functions in the body. It is very important for the human body to have adequate and appropriate amounts of iron. If the body lacks iron, some related side effects may occur, which in turn would affect the operation of daily physiological functions. According to the nutritional status of iron and the prevalence of iron deficiency in Taiwan, the survey of 1993-1994 revealed that the total iron deficiency rate among Taiwanese people over 4 years old, 2.1% are men and 10.7% are women. In conclusion, iron deficiency is more common in women than in men. In terms of iron intake, the national dietary nutrient reference intake issued by the Ministry of Health and Welfare recommended 10 mg per day for adult men and 15 mg for adult women. As for pregnant women and breastfeeding moms, it is necessary to consume 45 mg of iron daily.

For women, after they begin to menstruate, the loss of blood will increase the loss of iron, which will continue until menopause. Even though pregnant women do not have menstrual blood loss, due to the increase in their body tissues and the need for fetal growth, their demand for iron will be greater than usual. If the mother-to-be does not increase iron supplements in time during pregnancy, it may cause iron deficiency. The lack of iron could make you feel tired easy and miserable over small things in life; it could be influential.

Iron contributes to the formation of normal red blood cells; it's an essential component of heme and myoglobin, which also leads to the transportation and utilization of oxygen. Along with the progress of pregnancy, the body consumes more iron. In the lactation period, due to the secretion of milk, more iron is needed than usual. Under the condition of increased iron demand, the body will first use the stored iron to supply. However, if the iron supplement in the diet can not keep up with the consumption, it will make the iron stored in the body gradually reduced. When the iron stock is seriously depleted, it will have a significant negative impact. Therefore, pregnancy and lactation are the stages in which iron supplementation is particularly needed.


At realpromise, purity verification is the highest priority in every aspect. From the purity and safety of raw materials to quality control; to the finished product inspection, we choose to work with international third-party independent laboratory and certifiers to verify that each batch of our products meets our quality control requirements and production standards to ensure our quality can bring the greatest benefit to the customers. We inspect more than hundreds of items regarding safety, in order to ensure that you can have the highest purity products. Each batch of our products has passed at least 600 rigorous inspections and analyses, including four major heavy metal inspections, harmful microorganism inspections, 410 pesticide residue inspections and 233 qualitative screening test of chemicals for clinical use. In addition, some products will undergo activity monitoring, or do more purity testing for special ingredients. For example, Babe D3 has added 12 preservatives testing and 9 multi-mycotoxins testing. Furthermore, we additionally test for plasticizers on oil-based products. Our quality is worthy of your trust; please feel at ease to take the high-purity dietary supplements carefully designed by realpromise.


Our manufacturing factories have passed many certifications. Whether it is a manufacturing factory in Canada or Taiwan, we only choose the most stringent standard applicable for any process line to produce our carefully developed products.

The manufacturing factory in Taiwan is certified by a third-party organization - U.K. URS, which complies with HACCP and ISO 22000 safety regulations.

At realpromise, we make a conscious effort to avoid preservatives and harmful artificial chemical additives. When researching formulations and manufacturing, purity and safety are always our uncompromising principle. We insist on never using the following ingredients in our products, we will definitely keep a close eye out for you.


We are convinced that quality and efficacy are the cornerstones of nutritional supplements, which is also our guarantee to you. The use of inferior raw materials for the sake of cost will deeply affect the quality and effectiveness after consumption, so we only use the clinically-proven raw materials from well-known brands. In our opinion, the so-called high-quality dietary supplements must meet the following three standards :

Absorption Rate:For high-quality nutritional supplements, the efficacy after consumption depends on the absorption rate of the ingredients themselves. After all, the efficacy is highly related to the form of the ingredients. We insist on using the raw materials with highest-quality active form available to ensure our customers can achieve the best results after taking in our products.

Origin:The origin of the ingredients is the crucial point. Our principle in terms of choosing ingredients includes 1). The efficacy has been validated by a number of clinically trials. 2). The raw materials have to be from high-purity well-known brands. 3). The proof of high absorption rate and active form. Moreover, we never use inferior artificial chemicals to synthesize nutrients.

Form:Our products are mainly in the form of transparent capsules. Capsule formats are safer than tablets, because many additives have to add to tablets during molding process. Meanwhile, artificial colors and titanium dioxide are added to make colored capsules/tablets. All of these could cause potential harms to your body. Rejecting to use any risky substances in our products is our promise. In addition, realpromise is also extremely careful in the choice of capsule sizes. We understand the sizes of the capsules could affect the user acceptance and compliance. We intend to make the product easier to swallow, thus reducing the discomfort and rejection from the users. We always try to stand on the perspective of our consumers, and provide the best nutritional supplements without putting your feelings on the back burner.

Why does the color of FERROPRO capsule differ from general iron supplements on the market?

The iron supplements available on the market are usually in red color; they are actually artificial pigments on the capsule shell in order to show the effect of red replenishing heme. Artificial colors have been proven by many studies to have harmful effects. FERROPRO uses transparent capsule shell; it is natural and no other chemical additives are added. It presents the original color of the material; therefore, it is safer.

Does FERROPRO cause constipation?

The main ingredient of FERROPRO is sourced from US Albion® Ferrochel® (Ferrous Bisglycinate Chelate). It has been clinically proven to have no side effects, such as constipation or stomach discomfort. Besides, the common iron supplements on the market are generally high-dose. In fact, a single high dose is easier to cause side effects. Each FERROPRO capsule contains 15 mg of iron. The advantage is you could adjust the dose easily according to personal needs, and it does not cause the discomfort of constipation.

Why is the content level of vitamin B12 in FERRORPO that high?

According to the National Institutes of Health (NIH), the absorption rate of vitamin B12 in the body is only about 1/50 for normal people. The formula of FERROPRO is designed based on scientific researches; the content level is adjusted according to the influence of the absorption rate. Vitamin B12 can help the production of red blood cells, when it is supplemented with iron, the efficacy will be even better. 

FERROPRO is suggested to take one capsule one to two times daily. For convenience, can I take two capsules at the same time?

In terms of nutrients, excessive single dosing of some supplemental vitamins will affect the absorption, including vitamin C and calcium, they have the same characteristics. It is generally recommended to take a small amount in divided doses in order to provide a continuous supplementary effect in the human body for a day. Therefore, we would recommend not to take two capsules of FERROPRO at a time for better efficacy.
