Reishi Mushroom Capsules

Price varies
mushroomorganicmycelium-based

While a well-known brand, this product uses Reishi mycelium grown on brown rice rather than the 100% fruiting body extracts recommended in the category research. This results in a product that is high in starch filler (biomass) and lacks the dual-extraction and standardization for beta-glucans found in gold-standard mushroom adaptogens.
