At 1,000 mg per serving, you're at the entry point of the 1,000–3,000 mg range studied for **Lion's Mane** and cognitive support. The one RCT that showed meaningful results in mild cognitive impairment (Mori 2009) used 3,000 mg daily — so if you're chasing that benchmark, you'd need to triple the serving.

The extract quality here is notable. Organic fruiting body with hot water extraction, standardized to over 25% beta-glucans — the bioactive compounds believed to drive nerve growth factor production. That's a meaningful quality marker for a mushroom supplement.

Be realistic about what the science supports, though. Human clinical data on Lion's Mane is still thin — a handful of small trials, the largest with just 30 participants, and the cognitive benefits disappeared when participants stopped taking it.
