ACTIVE Chewable B12 supports red blood cell formation and macronutrient metabolism with a concentrated dose (1,000 mcg) of methylcobalamin, the body’s preferred active form of vitamin B12. B12-deficiency is one of the most common causes of nutrient-related anemia, especially among the elderly, with an estimated 11% of anemia cases in adults 65+ being B12-related. Vegan diets and metformin usage are also associated with increased risk of B12 deficiency.
