B vitamins are essential to life. These nutrients play a critical role in numerous biochemical reactions throughout the body. They are especially important for metabolism, energy production, and the maintenance of a healthy nervous system. B vitamins are water-soluble nutrients that are poorly stored in the body and readily eliminated after a short period of time. Therefore, in order to maintain optimum levels, B vitamins must be replenished daily. Mega B-Complex is a balanced blend of high-potency B-vitamins that can help you meet or exceed your daily requirements. This formula provides all of the essential B's, including a full 1,000 mcg of methylcobalamin - the biologically active form of vitamin B12. ‡This advanced formulation also includes Medium Chain Triglycerides (MCTs) as the foundation of our Liquid Soft-Gel delivery system.
