B Complex in Portugal: Vitamin B12, Folate, Biotin, B6 and Complete B Formulas

What the B complex is. The B complex brings together 8 water-soluble vitamins: B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B7 (biotin), B9 (folate) and B12. In this collection you will find complete B formulas from Life Extension, Swanson and Osavi, vitamin B12 from NOW Foods, Life Extension and Osavi, folate, biotin and vitamin B6.

What the authorised claims say. Thiamin, riboflavin, niacin, pantothenic acid, vitamin B6, vitamin B12 and biotin contribute to normal energy-yielding metabolism. Vitamin B6, vitamin B12 and folate contribute to the reduction of tiredness and fatigue and to normal psychological function. Thiamin contributes to the normal function of the heart and vitamin B6 to the regulation of hormonal activity. These claims apply to products providing at least 15% of the nutrient reference value (NRV) per daily dose.

Vitamin B12 in several forms. Vitamin B12 occurs naturally mainly in foods of animal origin, so people following a vegetarian or vegan diet should make sure they have a reliable source, such as fortified foods or supplements. You will find cyanocobalamin and methylcobalamin as lozenges, capsules and oral spray. Vitamin B12 contributes to normal red blood cell formation.

Folate and biotin. Folate contributes to maternal tissue growth during pregnancy and to normal blood formation; you will find folic acid and methylfolate. Biotin contributes to the maintenance of normal hair and skin. If you are pregnant or planning a pregnancy, talk to your doctor about the right dose.

Dosage and safety. Some products provide amounts far above the NRV: vitamin B6 100 mg exceeds the 12 mg/day upper level set by EFSA for adults, and folic acid has an upper level of 1000 mcg/day. High doses of biotin can interfere with laboratory tests. Do not exceed the recommended dose and add these vitamins up if you also take a multivitamin.
