Host Defense MyCommunity Review
MyCommunity® Capsules are presented by Host Defense as the brand's most comprehensive immune support formula, often used to promote year-round immune support. The page states that evidence from third-party, peer-reviewed research suggests that MyCommunity may support the immune response in healthy individuals. The product was the 2021 winner of the Taste for Life Immunity Essentials Award. The Benefits section lists comprehensive immune support, saying the product promotes the immune system's natural ability to communicate and react, encourages a healthy and balanced immune response, and supports the body's innate defense and repair systems. The page describes the formula as scientifically researched and links to a press release about immune activating properties of the MyCommunity mushroom blend. The Description section explains that a peer-reviewed, in vitro, human immune cell and immune cytokine response study looked at this multi-species mushroom blend. According to the page, the research on the 17-species blend indicated that immune cell signaling molecules were strongly engaged, that the formula assisted in a post-response return to a balanced state of homeostasis, and that it triggered the release of growth factors that help support daily tissue generative activity. The page also describes unique and complementary effects from using a multi-species blend of mushroom mycelium, with the compounds from each species said to work together to engage a wider range of immune cells. The page states the product is powered by mushroom mycelium and contains no fillers. It explains that a filler is an additive that adds bulk or weight without discernible health benefit, and says both the mushroom mycelium and the fermented rice substrate are researched and tested for health-supporting benefits. Directions state that adults take one half teaspoon one to three times per day. Despite the capsule product listing, the directions and description refer to a bioavailable powder with a mild flavor that can be mixed into a beverage, smoothie, or food recipe. The page includes a caution to consult a healthcare professional if you have a medical condition, take medications, or are pregnant or breastfeeding, and to keep out of reach of children. The product is offered in 30, 60, and 120 capsule bottles, with the 30 count listed as the selected size at a price of $20.95. The page notes that selecting a larger size qualifies for Subscribe and Save 20 percent. Bulk discounts of 20 percent on four or more items and 25 percent on twelve or more items are available with specific codes, and these cannot be combined with other offers. Shipping is calculated at checkout. The page includes standard disclaimers stating that the statements have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure, or prevent any disease. The page notes that product reviews reflect the views of contributors and that the brand has not verified their accuracy.
