Consumer advice
- • If you want mushroom supplements for immune support, look for products that:.
- • use fruiting body extracts rather than mycelium-on-grain,.
- • disclose beta-glucan content (aim for >20% beta-glucans), and.
- • list actual mg doses per species. Brands like Real Mushrooms or Nammex-sourced products are more transparent. If you already use this product and feel it helps, it's not harmful — but you're paying a premium without dose transparency. At $22.89 for 30 servings (~$0.76/serving), the price is reasonable for the category, but the lack of label disclosure is a real concern.
