EXCELLENT SOURCE OF B VITAMINS. The B vitamins support the health of the nerves, skin, eyes, hair, liver, mouth, muscles, gastrointestinal tract, cardiovascular system, and immune system. They also support proper brain function, energy production, metabolism and maintaining positive mood and stress levels.

When vitamins are ingested, they travel from the digestive tract through the peritoneum and on to the liver, where they are changed into their active “coenzyme” form. The body cannot use them until they are in this form. Coenzymate B Complex provides B vitamins in their coenzyme form, making active B vitamins available to the body immediately.

SUGGESTED USE. 2 lozenges daily. For best results, allow to dissolve in the mouth before swallowing.
