Studies have shown Cordyceps Mushrooms having potential health benefits for the immune system, cardiovascular system, cellular energy processes, athletic performance and general mood and focus (and, some studies indicate a role in longevity/anti-aging). So, this is one the mushrooms that I consume daily, in bulk powder form or capsule supplements. Each capsule contains 300mg of Cordyceps Mushroom Extract, using only 100% Fruiting Body (no mycelium). I am impressed that it’s only fruiting bodies and in extract form (which means it’s concentrated). Unfortunately, they do not provide the extract ration (which defines the concentration). Also appreciate that the capsules contain no fillers. So, it’s just pure Cordyceps Mushroom Extract, with more than 30% Beta D-Glucans. (Beta D-Glucans are the compounds in mushrooms that are key to the health benefits.) The product details notes that the supplement is: Organic, Vegan, Gluten-Free, Non-GMO, Certified Kosher. According to the product details page, the organic certification is USDA Organic, which inspires confidence in the purity and integrity of the ingredients. And, it seems that the USDA Organic is displayed on the new package label. Unfortunately, it's absent from the old label, which I received. As such, I cannot factor USDA Organic as being applicable. The Supplement Facts does note that the cordyceps is organic and 100% fruiting bodies. The lack of the USDA certification dings the ratings. I’m glad to have this mushroom supplement in my vitamin, supplement resources. I feel it’s a high quality product, and attains a 4.5 star rating, with a high level recommendation.
