Buying Guide
Extract Source: Fruiting Body vs. Mycelium
The most critical factor in any mushroom supplement is whether it uses the fruiting body (the part you see above ground) or mycelium grown on grain. Fruiting bodies contain significantly higher levels of beta-glucans, the compounds linked to cognitive and immune benefits. Many brands use mycelium on grain to cut costs, which dilutes potency with starch. For lion’s mane for cognitive support, you want a product labeled as 100% fruiting body extract.
Products like the Real Mushrooms Lion’s Mane Capsules, Brain excel here, as they are made exclusively from organic fruiting bodies. Always check the label to avoid mycelium fillers.
Potency and Dosage Form
Lion’s mane supplements come in capsules, liquids, and powders. Capsules offer convenience and precise dosing, while liquid extracts may provide faster absorption. Look for a serving size that delivers at least 1,000 mg of extract. The Lions Mane Liquid – USDA Organic Lions Mane provides 1,200 mg per serving, making it a potent option for those who prefer a liquid. Consider your lifestyle: capsules are travel-friendly, while liquids can be added to drinks.
