Overview

Source Naturals B-12 Fast Melt is a dietary supplement centered on methylcobalamin, the active coenzyme form of vitamin B-12. It is presented as a quick-dissolving tablet designed to support energy production and nerve health, while offering a form of B-12 that differs from the more common cyanocobalamin type.

The formula is intended to provide an easily absorbed source of vitamin B-12. This can be especially relevant for vegans and older adults, since vitamin B-12 is naturally found in foods such as meat, seafood, eggs, and dairy, and absorption can become less efficient with age. The fast-melt format is meant to make the tablet dissolve in the mouth before it is swallowed.

Beyond general B-12 support, the product is described as helping maintain healthy red blood cell function, normal homocysteine regulation, and the body’s production of SAMe, an important methyl donor. It is also suitable for vegetarians and vegans.
