The Secret Is ErgoD2®
ErgoD2® is a proprietary, natural combination of the amino acid Ergothioneine and Vitamin D2, a combination that cannot be manufactured by humans and can be obtained only through diet. This natural combination, found within specialty mushroom plants, and enriched through a patented process, is incorporated into our proprietary supplements and external skin products. This signature component, powered by ErgoD2®, is one of the most potent antioxidants known to date.

Understanding Hair Loss

Hair follicles live within the skin and not on its surface. ErgoD2® contained in the GROH® supplements and in all GROH® beauty products, supplies the key nutrients for stem cell survival and hair growth.

How GROH® Awakens Hair Follicles

The basic nutrients that feed hair follicles must come from within to allow cells to function. The highest concentration of the Ergothioneine transporter is found in the stem cell of the hair follicle.

Vitamin D & Female Hair Loss

30% of women suffer from hair loss. Vitamin D helps play an important role in stopping this occurrence. Our proprietary enhancement purification technology increases the vitamin D levels nearly 1,000 times the amount found in nature.
