Key Benefits of B Complex Vitamin In Liquid

  1. Supports Healthy Energy Production

    Liquid B complex vitamins are important cofactors in cellular energy production. Thiamin, riboflavin, and pantothenic acid help convert food into energy.

  2. Supports Red Blood Cell Health

    Vitamins B6, B9 (folic acid or P-aminobutyric acid) and B12 are important for red blood cell formation. Therefore, the liquid b complex vitamins B9 and B12 in Primergen-V support healthy red blood cell formation and prevent macrocytic anemia.

  3. Brain and Neuronal Health

    The deficiency of many B vitamins result in brain fog, numbness or weakness, and neuropathy symptoms because these vitamins are important for neuronal function.

  4. Eyesight

    Vitamins A is crucial for eye health. Beta-carotene, vitamin C, and vitamin E are antioxidants that can protect the eyes from damaging oxidative stress. In addition, vitamins B6, B9, and B12 protect the eyes from oxidative stress that may increase the risk for age-related macular degeneration. 

  5. Immune Function

    Vitamin A and D are important for a strong and balanced immune function. Vitamin B6 supports biochemical reactions in the immune system. Lastly, antioxidants such as beta-carotene, vitamin C, and vitamin E counteract the harmful effects of oxidative stress and inflammation.

  6. Provides a Source of Methyl Group

    Methylation (one carbon metabolism) is important for epigenetics and the metabolism of neurotransmitters, hormones, homocysteine, folate, amino acids, and many more. Primergen-V contains methylated vitamin B12 (methylcobalamin) and methylsulfonylmethane, which are donors of methyl groups. It also contains dimethylglycine to counteract the effects of many much methyl donors.
