Combination of B-vitamins in their most active forms

• Includes the body’s preferred active forms of vitamins B₆, and B₁₂, riboflavin and folate
• Helps in energy metabolism and in tissue formation. 
• Helps to form red blood cells.
• Helps in the normal function of the immune system.
• Helps to prevent thiamine, riboflavin, niacin, vitamin B₆, folate, vitamin B₁₂, biotin and pantothenic acid deficiency

Each single-capsule serving of Active B Complex provides the adult Recommended Dietary Allowance (RDA) for the entire B-vitamin family, including thiamine, riboflavin, niacinamide, pantothenic acid, vitamin B6, biotin, folate and vitamin B₁₂. Active B Complex uses the preferred active forms of vitamins B₂ (riboflavin-5’-phosphate), B₆ (pyridoxal-5’-phosphate), folate (Metafolin^®), and B₁₂ (methylcobalamin). Metafolin^® is a calcium salt of L-methylfolate, the primary active form of folate within the body. In comparison with folic acid, L-methylfolate appears to have a significantly higher bioavailability. For example, in healthy women supplemented with an equivalent amount (~400 mcg) of either L-methylfolate or folic acid for 24 weeks, red blood cell folate concentrations were significantly higher in women that received the L-methylfolate supplmement.¹
