Why is the methylcobalamin form of Vitamin B-12 a better form overall than regular B-12? Also, is it safe and where does it come from?
Most B vitamins function in the body only in their coenzyme (or active) forms, and the regular forms as found in our B-12 or certain B-complex products have to be converted into the coenzyme forms before they can do their job. These coenzyme forms, though, are usually much more expensive and are considered more potent than standard vitamin forms. Methylcobalamin is one of these coenzyme forms. It is derived via microbial fermentation, and since it is water soluble has a large safety margin.
