  • Odor-Free...

    ACTIV B-COMPLEX is a new generation of high strength vitamin B-Complex supplement for enhanced absorption and efficacy; it helps our body maintain normal energy metabolism. The unique formula in ACTIV B-COMPLEX not only reduce the strong and unpleasant odor of the general vitamin B-Complex supplement, but also prevent the aftereffect of nausea after consumption. It is a top-of-the-line vitamin B-Complex supplement that has been favored by many medical professionals and consumers.

    Real Promise has added the latest generation of “BODY-READY” methyltetrahydrofolate (6S)-5-MTHF – Quatrefolic® into 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. It surpasses the high absorption rate of the general synthetic folic acid, which allows you to intake less, but achieves better results.

  • high-efficiency Vitamin B12 - Methylcobalamin...

    ACTIV B-COMPLEX supplement also 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.

  • More Comprehensive by Choline and Inositol...

    In addition to contain the basic vitamin B group, Real Promise has upgraded ACTIV B-COMPLEX by adding the ingredients of Choline and Inositol. With the effect of Choline and Inositol, ACTIV B-COMPLEX becomes more comprehensive to the human body. Choline is known to play a key role in fetus’s development. Studies have suggested that pregnant and lactating women should ensure they get adequate Choline in their diet or supplementations. 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 has a lot of health-promoting effects on female’s well-being; it is an irreplaceable nutrient, especially for pregnancy women. Some professional studies from the Taiwan Maternal Fetal Medicine Society have shown how important this ingredient is to women. ACTIV B-COMPLEX is an advanced, well-balanced vitamin B-complex product. It contains more types of vitamin Bs than the general products on the market.

  • real promise on the best quality...

    In addition, as the commitment we have made to our customers, there is no artificial colors, artificial flavors, preservatives, and harmful chemicals added in ACTIV B-COMPLEX. Quality-wise, ACTIV B-COMPLEX chose 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.
