Buying Guide: How to Choose the Best Lion’s Mane Supplement
1. Fruiting Body vs. Mycelium: What Matters?
Lion’s mane supplements are made from either the fruiting body (the part you see) or mycelium grown on grain. Fruiting body extracts typically contain higher beta-glucans and less starch. Brands like Real Mushrooms emphasize 100% fruiting body. If purity is your priority, look for “fruiting body only” on the label.
