Sometimes you may get B vitamin powder residue on the capsules, usually yellow in color. Again, this is a normal occurrence. There is often a small amount of powder that escapes during the encapsulation process, and it sometimes coats the outside of the capsules.

 

 

The enteric coating does slow the release of the nutrients somewhat by allowing them to pass through the stomach intact but no this does not create a time release product. It is tested to readily disintegrate in simulated intestinal conditions.
 

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.
