Not all vitamin forms are the same, nor are they utilized by the body in the same way. Many must first be converted into active coenzyme forms before they can actually go to work in the body. Source Naturals® provides these in coenzymated™ forms to provide you with optimal amounts of active ingredients. Vitamin B-12, also known as cobalamin, is a perfect example. Vitamin B-12 is an important multi-purpose nutrient supporting healthy red blood cell formation, homocysteine levels, nerves, and DNA. Methylcobalamin is a more biologically active form of cobalamin (B-12) than the commonly used cyanocobalamin form. This coenzyme form eliminates intermediate metabolic conversion steps, supporting easy assimilation by the body. Time and again, Source Naturals® will choose the preferred form of the nutrient for you, because not all forms are the same.
