Advanced Absorption Mega B-Complex
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 oil for the Liquid Soft-Gel delivery system in this product.* MCTs are a preferred source of quick cellular energy.* MCTs are rapidly absorbed into the bloodstream and immediately converted into energy at the cellular level.*
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.*
High Potency B-Vitamins:
- Biotin B7
- B12
- Folate B9
- B1
- B2
- B3
- B5
- B6
Liquid Soft Gel Delivery
The nutrients in our Liquid Soft Gel supplements are released fast. Other forms of delivery contain binders and fillers that may cause stomach upset and offer no nutritional value. Advanced Liquid Soft Gels provide a premium easy-to-swallow delivery system that allows us to combine our nutritious oils such as Flaxseed Oil, and MCT Oil for additional nutritional benefits. But wait! We didn’t stop there. Every Liquid Soft Gel includes our special Bioperine Complex which enhances the bioavailability, absorption and potency of many nutrients.
