Why are tinctures the best way to take Lion's Mane? Most Lion’s Mane extract powders and Lion’s Mane capsules miss the mark. Lion’s Mane’s most potent compounds, like hericenones and erinacines, require alcohol extraction—something that powders made from hot water extractions can’t unlock. On top of that, many bulk powders are padded with fillers and imported from questionable supply chains. While hot water extracts have some benefits, a properly made double-extracted tincture (alcohol and hot water) is the most effective preparation.
How to Use Lion's Mane Tincture

Take tinctures straight or add them to beverages like coffee or smoothies at a comfortable drinking temperature. If you're already taking other mushroom tinctures, you can safely add up to 4mL of Lion's Mane without needing to change your other dosages.

Why Alcohol?
Lion’s Mane requires alcohol to properly extract and unlock its beneficial compounds. Without it, the full range of Lion's Mane’s potential benefits, especially those for cognitive support, may not be accessible. Our double extraction process ensures you get the most out of every drop.
Frequently asked question
There’s no set “maximum dose” of Lion’s Mane, but most research supports staying under about 3,000 mg per day. Our tincture provides 417 mg per 4 ml serving. It’s safe to gradually work up beyond the suggested 4 ml serving, but exceeding 3,000 mg (or 6 servings) may increase the chance of Lion’s Mane side effects. Those with mushroom allergies, underlying conditions, or who are pregnant or nursing should consult a healthcare professional before higher intake.
Our tincture provides 417 mg per 4 ml serving, so many people start with one serving and adjust as needed. Some take 2–3 servings (8–12 ml) daily for ongoing use. Staying under about 3,000 mg helps minimize the chance of mild digestive discomfort. Extracted preparations are more potent than whole mushroom powder, so keep that in mind when moving up.
