B Vitamins work together for energy and coping with stress
Many of the enzyme systems that manage energy generation, methyl group transfers, antioxidant defense, and numerous other metabolic pathways require more than one B vitamin in order to function. The methyl transfer enzyme that recycles homocysteine (methionine synthase) must have both fully active folate and fully active vitamin B12 available, in order to carry out its pivotal function. The mitochondria, which generate over 90 percent of our life energy, need all the B vitamins to make energy. The B vitamins’ fundamental importance to metabolism helps explain their importance to the body’s defenses against stress. Clinically, they can help the individual cope with emotional stress. Lifestyle stressors such as smoking and excessive alcohol consumption tend to deplete them from the body. So does physical work and intensive exercise.

  • Supplies only the best-utilized B vitamin forms. Most B vitamin supplements use cheap forms that are not optimally utilized in the body. This formulation does not compromise—it provides generous amounts of the most active B vitamers.
  • Substitutes naturally fully active folate instead of synthetic folic acid. Folic acid is an artificial folate that is difficult for the body to assimilate. This formulation instead provides the body’s most fully active folate, MTHF (methyl-tetra-hydro-folate).
  • Provides sufficient, fully active vitamin B12. Very few supplements provide sufficient amounts of active vitamin B12. This formulation provides 1000 micrograms of fully active B12 to help ensure excellent oral absorption.
