Product Details

Water-soluble B vitamins are not stored in the body and must be replenished daily. NOW®’s B-100 is a multiple B-vitamin product designed to provide consumers with therapeutic quantities of B vitamins in one complete supplement.

NOW®’s B-100 Complex is a synergistic blend containing all of the important B vitamins needed to maintain good health. Each B vitamin has a unique role, but when combined they work together as coenzymes to metabolize proteins, carbohydrates and fats. B Complex Vitamins are needed for proper maintenance of the nervous system, proper functioning and growth of tissue cells and energy production. The body's need for B Complex vitamins greatly increases in case of mental or physical stress, as well as poor eating habits.


Adult Dosage: Take 1 capsule daily with meals.
