Progressive Laboratories Better B 90 Capsules

What the brand says

B vitamins are essential nutrients that participate in thousands of metabolic reactions within the body. B vitamins are needed to convert dietary fuels, such as carbohydrates and fats into energy, and for the synthesis of important biochemicals such as steroid hormones and DNA. Most vitamin supplements do not provide B vitamins in their active form. Instead, they use inactive precursors the body must first activate before the vitamins can become useful. Better B is the next step in B vitamin supplementation; it uses advanced, activated forms of B vitamins to achieve better nutritional results.
