This triple-mushroom blend combines **Reishi**, **Shiitake**, and **Maitake** for immune support, but two of the three are well below clinical doses. Reishi totals about 130mg per capsule (including a standardized extract with 4% triterpenoids and 7% beta-glucans), while research typically uses 1,000–3,000mg daily. Even at two capsules, you're getting only about 26% of the minimum studied Reishi dose.
**Maitake** is the best-dosed of the three — it comes as a 4:1 extract, bringing its equivalent to about 400mg per capsule. At two capsules daily, you'd reach roughly 800mg equivalent, within the 500–2,500mg clinical range. The standardized Reishi extract with defined triterpenoid and beta-glucan levels is a plus for quality.
The core tradeoff is that splitting capsule space three ways leaves Reishi and Shiitake underdosed. If immune support is your primary goal, you'd benefit from a higher daily capsule count or a formula focused on fewer mushrooms at full clinical doses.
