This complex with active vitamin B6 and folate supports the body well during periods of fatigue and stress. I noticed that I have more energy, it is easier to concentrate, and there is less nervous tension. It has a positive effect on the nervous system, helping to cope better with emotional stress and mood swings. It also supports the liver and general cleansing processes in the body. Folate in this form is important for the health of blood vessels and blood, and B6 is involved in hormonal balance. I would like to separately note the effect on the skin and mucous membranes - faster healing, less dryness and cracks. The formulas are active, well absorbed

Excellent!

I have several proven complexes that include the entire B group, from various manufacturers. Please visit my reviews page to see options for a single B complex from various manufacturers whose supplement quality I trust. As a rule, when taking any B vitamin, other B vitamins are included to enhance its effectiveness. Therefore, if you are taking a B complex, rather than a single supplement, it is important to check the ingredients to ensure they are bioactive, coenzyme forms. B vitamins work best in their active forms. They do not require additional transformation in the body to provide their beneficial properties. BioActive B vitamin complex from Terry Naturally presents the vitamins in their metabolically active forms. For example, this means that vitamin B6 (pyridoxine) is in its active form, pyridoxal-5-phosphate, or P-5-P. Vitamin B9, known as folic acid, is in its metabolically active form, folate. Vitamin B12 without the toxic cyanide molecule—methylcobalamin—will better support your nervous system. The package contains 60 vegetarian capsules. B vitamins play an important role in metabolism and the production of energy from food. A B-complex vitamin was prescribed for a child. When the child was younger, tablets and capsules weren't an option, so we immediately chose the liquid form on the website. We ordered a similar complex from KAL, but in liquid form (droplets). You can see it on my reviews page. We tried Active B complex from Zahler. It has a very good composition! I highly recommend it. However, the tablet/caplet size was very difficult for our child to swallow. When BioActive from Terry Naturally appeared on the website, we ordered it. We have had positive experiences with supplements from Terry Naturally. We had one of the best options for Magnesium in combination with Glycine on the website for children from the time they can swallow a capsule, from this manufacturer. The child swallows the capsule size and dosage from this particular manufacturer without any problem. We're addressing our child's iron deficiency. Therefore, in addition to iron supplements, we ordered a complex of active forms of group B. The package is designed for two months of use. We, the adults, notice a surge of energy when taking it. Our child doesn't report any energy. The results will be evident after repeat testing. But we're already pleased that our child has no difficulty taking the supplement.

Super BIO ACTIVE vit.B
Verified purchase
I have been looking for such a super composition for a long time and also the most active forms of vit. B. The capsule ingredient contains 3 most necessary vitamins for the nervous system and the body as a whole vit. B 6, folic acid and B12 in therapeutic doses, which is quite rare in complexes. The capsule size is moderate. The taste is neutral. The packaging is intact. B vitamins are water-soluble, so they are very quickly excreted from the body.

We took these vitamins together for good absorption of iron, since iron is not absorbed with a deficiency of vitamin B12. I hope everything went well. And these vitamins are simply necessary for female beauty. P.S. I took tests after taking them and the results were good: B6 and B12 are normal. This means there is quality and effectiveness.
