Bests & Worsts Reviews from Amazon

Absolutely the only company I trust for medicinal mushrooms. Sure, they are expensive, but that is because they source from Nammex. Nammex uses the fruiting body - NOT the mycelium - and that's what you want. Think of the mycelium as the roots of a tree and the mushroom as the trunk and leaves. Mushroom companies that tout high levels of polysaccharides are really indicating that there is a lot of starch in their product. This is because the mycelium (the easiest to grow, but least potent, part of the mushroom) is grown in grain and full of starch. What you want in a medicinal mushroom is beta-glucans, and REAL Mushrooms provides this. Nammex tests for beta-glucans. As far as this Lions Mane product, I do notice increased focus. I take it mostly to keep my brain healthy, not for any short term benefits, really.
