Uses: The Big One® with Iron provides essential vitamins and minerals to maintain good health. Iron is a component of blood hemoglobin, critical for oxygen transport, and myoglobin, the oxygen carrier in muscles. Inorganic iron supplements such as iron sulfate are poorly absorbed and can cause gastric distress.

Featuring the bioavailable methylated forms of folate (L-methylfolate) and B-12 (methylcobalamin), phosphorylated forms of riboflavin and B-6, chelated minerals, natural mixed carotenoids, and natural vitamin E, The Big One with Iron supports:


Cellular health: Antioxidants Vitamin A, Vitamin C, and Vitamin E and selenium reduce oxidative stress by scavenging free-radicals that can cause cellular damage.


Bone health: Vitamin D and vitamin K- especially K-2- maintain calcium homeostasis, allowing calcium to go from the bloodstream into bones. Zinc, copper, manganese and boron also support bone mineralization.


Immune system function: Vitamin A and Vitamin D are immunomodulators. Zinc is required for T-lymphocyte activity.


Energy production: The B vitamins thiamine, riboflavin, niacinamide, B-6, biotin and pantothenic acid are cofactors for enzymes needed for cellular energy production through metabolism of proteins, carbohydrates, and fats.


Nerve health: Thiamine, folate, B-12 are involved in neural development and neurotransmitter synthesis.


Cardio health: Methylfolate and B-6 are required for homocysteine metabolism. Thiamin is necessary for synthesis of D-ribose. High serum vitamin E levels have been associated with cardiovascular heath.


Glucose metabolism: Chromium and vanadium support normal insulin function and glycemic control.


Thyroid health: Iodine is a precursor in the formation of thyroid hormones.
