The active ingredient within GROH® is ErgoD2®. Our proprietary, potent antioxidant has its own unique specific transporter system within the human body. This transporter is present in the outer cell wall membrane of human cells and is highly expressed in healthy skin, hair, scalp, nails, and lashes.

What Is Ergothioneine (ErgoD2®) & Why Is It Important?

ErgoD2® is a unique 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 oral supplements and external skin products. This signature component, powered by ErgoD2®, is one of the most potent antioxidants known to date.

How Does ErgoD2® Work?

GROH® beauty treatments, powered by ErgoD2®, work internally and externally with the body’s complex biological system to help support healthy skin, scalp, hair, nails, and lashes—from head to toe.

How GROH® Gives a Natural Boost in Energy

Use of ErgoD2® supplements has been associated with an increase in iron levels and hemoglobin within blood. Iron within hemoglobin carries oxygen molecules, which are needed for improved cell function and increased energy.

How Does ErgoD2® Help My Hair Grow? 

A hair follicle lives inside and anchors each hair into the skin. Living cells divide and grow to build and push out the hair shaft that one sees. There is no question that proper nutrition of a follicle has to start from within, and be delivered by blood to the hair follicle stem cells. 

Proprietary research has shown that one of the highest concentrations of the Ergothioneine transporter is found in the stem cells of hair follicles from which hair cells are produced. Groh® beauty treatments, powered by ErgoD2®, supply nutrients important in stem cell function, and promote restoration of normal hair growth.

The Link Between Vitamin D & Female Hair Loss

30% of women suffer from hair loss, often referred to as Telogen Effluvium (TE) and Female Pattern Hair Loss (FPHL). Hair loss can have devastating psychological consequences. Most current treatment options for TE and FPHL require the use of drugs and medications with associated side effects. Scientists have found lower Vitamin D2 levels in females studied with hair loss. Furthermore, the Vitamin D2 deficiency in those studied increases, as hair loss increases and with disease severity.

The supplement formulation found in GROH® beauty products, ErgoD2®, is an excellent source of Vitamin D2, which can help correct the vitamin deficiency that has been implicated in hair loss. Patented UV light technology is used during the ErgoD2® formulation process to increase vitamin D2 levels by more than 1,000 times the normal amounts found in nature.

How Does GROH® Help Make Skin More Vibrant & Youthful? 

An important sublayer of skin called the Stratum Spinosum creates the structural skeleton for skin and provides strength, elasticity, and flexibility to the outer layer of skin, making it a key component of the external physical appearance of a person’s skin.

The Ergo transporter protein is highly expressed in this layer, and Groh® beauty products, powered by ErgoD2®, actively and directly nourishes this important skin layer.

Within 3 to 4 weeks following Groh® treatment, users start seeing immediate improvement in their skin texture and turgor. The treatment helps to create a natural smoothing of facial wrinkles while refining the surfaces of the skin.

Our Signature Blend of Mushrooms 

Our hand-selected specialty mushroom blend is found in the Pacific Northwest, a perfect climate where mushrooms thrive naturally in forests and caves. 

We analyze and select mushrooms that have the highest levels of ergothioneine, selenomethioneine, selenium, polyphenols, beta-glucans, as well as glutathione. 

The key objective of Groh® beauty treatments is to nourish cells within the body, especially stem cells that divide and form new cells, as well as boost the body’s immune defense system. To be effective, a nutritional approach must start within the body and is integral to the maintenance, as well as development, of healthy skin, scalp, hair, nails, and lashes.

How Does GROH® Stimulate my Cells & Support my Immune Health?

Cellular studies have demonstrated the antioxidant and cell protective capabilities of ergothioneine, a key component of ErgoD2®. Vitamin D2 has been shown to have a positive regulatory effect on immune function. ErgoD2® contains both of these critically needed nutrients.

How Groh® Improves Naturally Fuller Brows & Lashes

Healthy hair follicles are needed for normal-appearing eyelashes and eyebrows. ErgoD2® is the answer to correct nutritional deficiencies that have developed over time within these hair follicles. 

How Groh® Helps Your Nails 

Building beauty from the inside out, ErgoD2® supplies nutrients to the cells that produce the tough protective protein which make up a nail, called alpha-keratin. The live portion of a nail is called the matrix, which produces cells that become the nail plate that one sees. Proper nutrition is needed to encourage nail growth and strength. 

Groh®, powered by ErgoD2®, decreases inflammation in the nail bed caused by oxidative stress. The ErgoD2® feeds the stem cells that are needed to divide and differentiate into the components that make up normal-appearing nails.
