🧪 Formulation Notes

1,000 mcg B12 Methylcobalamin! with 'Quick Energy" MCT's High Potency B-Vitamins: Biotin B7 B12 Folate B9 B1 B2 B3 B5 B6

Why supplement with B-vitamins? 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. Advanced Absorption 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 (MCT's) as the foundation of our Liquid Soft-Gel delivery system. MCT's are a preferred source of quick cellular energy. MCT's are rapidly absorbed into the bloodstream and immediately converted into energy at the cellular level.

What makes us different: Liquid Soft-Gels - The nutrients in these easy-to-swallow Liquid Soft-Gels are released fast. Other forms of delivery can contain binders and fillers that may cause stomach upset and offer no nutritional value. Advanced Liquid Soft- Gels provide an optimum delivery system.

No preservatives added.
