In Addition to Supporting Hair Growth & Skin Health -Groh® Daily Vitality Boost Also Provides Major Support to Your Immune System.

ErgoD2® is a unique natural combination of the amino acid ergothioneine & vitamin D2, a combination that cannot be manufactured by the human body 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 supplement - Daily Vitality Boost. This signature component is one of the most potent antioxidants known to date.

Cellular studies have demonstrated the antioxidant and cell protective capabilities of ergothioneine (3). Vitamin D2 has been shown to have a positive regulatory effect on immune function (4). ErgoD2® contains both of these critically needed nutrients.



The Ergothioneine that’s packed into our Daily Vitality Boost capsules delivers both antioxidant and immune support, due to its naturally occurring free radical defenders and our proprietary method of packing in a super high concentration of Vitamin D2. Both play an important role in maintaining a healthy immune system.


Groh® Daily Vitality Boost capsules are a convenient way to include the beneficial ingredient EgroD2® along with essential immune-supportive nutrients. For optimal protection, consume Groh® Daily Vitality Boost twice a day, and throughout the year. You can also start immediately at the onset of those nagging signs such as an itchy throat, sneezing & sniffles.


Groh® Daily Vitality Boost is a natural whole food. All ingredients are non-GMO and is safe to take with all foods. Additionally, Groh® Daily Vitality Boost is vegan and does not contain animal by-products.


Groh® Daily Vitality Boost contains NO preservatives, NO artificial colors or flavorings, so you can trust that you are using a natural immune system boosting supplement without ingredients your body doesn’t need!
