ACTIV B-COMPLEX is a new generation of high strength vitamin B-complex supplement for enhanced absorption and efficacy. The formulation is advanced and well-balanced. In addition to the basic vitamin Bs, realpromise also added ingredient "choline" and "inositol", which have a more comprehensive effect on the human body but usually ignored by the general B-complex supplements. Each of the ten vitamin Bs has different responsibility, they help "convert" the ingested nutrients into the energy needed by the body. In other words, B vitamins cannot provide energy "directly”; rather, they help convert dietary energy into ATP (adenosine triphosphate), the form of energy that our body uses.

realpromise chose the latest generation of “Body-Ready” methyltetrahydrofolate (6S)-5-MTHF – Quatrefolic® for ACTIV B-COMPLEX. Quatrefolic® is a natural reduced folate, it has been proven to be more active and stored in the body. It has long lasting stability, super high water solubility, enhanced bioavailability as well as good safety. In fact, Quatrefolic® is 100 times more soluble in water than 5-MTHF calcium salt and it surpasses the high absorption rate of the general synthetic folic acid, which allows you to intake less, but achieves better results. After a long period of evaluation and review, the US FDA has officially approved Quatrefolic® as a safe [New Dietary Ingredient (NDI)].

ACTIV B-COMPLEX includes the high-efficiency, high-absorption and 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.

ACTIV B-COMPLEX also contains "Choline", an essential nutrient for the human body, which is also known to play a key role in fetus’s development. American Pregnancy Association (APA) has suggested that pregnant and lactating women should ensure they get adequate choline in their diet or supplementations, which can help your baby win at the starting point. Meanwhile, as our age increases, the amount of synthesis in the body is relatively decreased, choline is also a necessary nutrient for improving the quality of our later life.

"Inositol" is added to ACTIV B-COMPLEX as well, which has proven to have a lot of health-promoting effects on female’s well-being. It is an irreplaceable nutrient, especially for pregnancy women. Inositol is often referred to as vitamin B8; some professional studies from the Taiwan Maternal Fetal Medicine Society have shown how important this ingredient is to women. It can support metabolism, regulate physiological functions and adjust physical condition. The confirmation has medical professionals placed high hopes on the use of this nutrient for women in need.


ACTIV B-COMPLEX is a rare, high concentration, top-grade B-complex supplement. Compared with the same products on the market, ACTIV B-COMPLEX is more advanced and well-balanced, which could fully support the daily nutritional needs of adult men and women. 


The unique formula in ACTIV B-COMPLEX not only greatly reduces the strong and unpleasant odor, but also prevents the aftereffect of nausea and hiccups after consumption. It is a top-of-the-line vitamin B-complex supplement that has been favored by many medical professionals and consumers.


The vitamin B groups used in ACTIV B-COMPLEX are long-efficiency, activated superior form and high absorption. It reminds in the body for a longer period of time, which could benefit our body in many ways.

Vitamin B-complex is necessary for the human body, but with a balanced diet , vitamin B-complex can turn into a key supporting role for promoting metabolism, and enhancing physical strength. Whether you need to supplement vitamin Bs, or what kind of people may develop B vitamin deficiencies, you can use the following information as the reference :

People with unbalanced diet are prone to lack of B vitamins. There are many foods containing B vitamins. All kinds of vegetables, fruits, milk, eggs, beans, fish, meat and nuts contain different vitamin B. If your life is too busy to have variety of foods in a balanced manner, you should take additional B-complex dietary supplements.

For vegetarians and elders, it is better to add B vitamins supplementation. Vitamin B12 is mainly found in animal foods. Vegetarians who do not consume eggs, dairy, or fish are thought to be at particular risk of vitamin B deficiency. Meanwhile, for elders, they are very likely limited in their ability to absorb vitamin B12. Under these circumstances, to increase the supplementation of vitamin B12 is strongly recommended.

For drinkers, because their body consumes a large amount of vitamin B, the demand for B vitamin gets higher. B vitamins can help metabolism, so it is good to supplement more B vitamins for people who drink alcohol a lot.

For pregnant women and breastfeeding moms, their body requires even more nutrients. It is important to make sure the supplementation of vitamins is sufficient. In particular, folate can help the normal development and growth of the fetus; moreover, vitamins B6, B12 and choline have specific effects for both mother and baby as well.

For those who love sweets, they need to take more vitamin Bs. Excessive sugar intake could make the body's vitamin Bs lack due to excessive consumption. That leaves you feeling less energized, as a result. The solution is to reduce sweet food intake and supplement vitamin Bs.

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.

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.
