Irwin Naturals® Mega B-Complex™ is a balanced blend of high-potency B-vitamins which are essential to life. B-vitamins are water-soluble and are poorly stored. They are eliminated after a short amount of time, and thus need to be replenished daily. All you need is 1 soft-gel per day, and you are good to go. Mega B-Complex™ also includes Medium Chain Triglycerides (MCTs) as the foundation of Irwin Naturals'® Liquid Soft-Gel delivery system. 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.
