Why your follicles are asleep

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.

Daily Vitality Boost

  • All-natural supplement offers nutritional support for cellular function, which results in healthier hair, skin, scalp, nails, and lashes.


  • Helps stimulate Hair growth, resilient younger-looking skin with fewer noticeable fine lines and wrinkles, strengthens and fortifies nails as it helps stimulates growth in the brows and lashes.

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.

Younger, Youthful Skin

The middle layer of the skin (stratum spongiosum), is a primary location of the ergothioneine transporter and improves the elasticity and hydration of your skin.

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.
