🧪 Formulation Notes

Convenient vial delivery system with complete liquid B-complex

Vegetarian/Vegan

Energy boost

B Vitamins are essential components in most major metabolic reactions as they play an important role in energy production, including the metabolism of lipids, carbohydrates, and proteins. Vitamin B-12 facilitates energy production and is required for nucleic acid (DNA) synthesis, methionine synthesis from cysteine, and normal myelin synthesis in the nervous system. Along with vitamin B-6 and folic acid, adequate levels of vitamin B12 are required to maintain healthy plasma homocysteine levels. The elderly and strict vegetarians are often at risk for Vitamin B12 deficiency, either due to low dietary intake or decreased absorption. Nutri-Dose B-12 10,000 mcg is a convenient and palatable liquid formulation that is absorbed quickly by the body, delivering rapid, energizing nutrition.

These convenient liquid vials are perfect as an on-the-go, high-potency source of B12 energy. Quickly delivers 10,000 mcg of vitamin B12 Provides a full spectrum of B vitamins Sugar free, sweetened with xylitol Refreshing, Natural flavor blend of raspberry, strawberry and cherry
