Analysis

This is the same high-potency Solgar B-100 formula but in a more economical size. It is designed to support your body's energy production by providing the cofactors needed for the Krebs cycle. It is particularly good for anyone wanting to support their skin health and metabolic rate through the winter or during busy work seasons.

The formula includes choline bitartrate and inositol, which help support your brain cell membranes and signaling. Because it comes in a vegetable capsule, it dissolves quickly and is easy for your system to handle. This is a great choice if you prefer capsules over tablets and want a brand with high purity standards.
