How to take it
- General Cognitive Support: 500–1,000 mg daily of standardised extract, typically divided into 2–3 doses.
- Mild Cognitive Impairment: 1,050–3,000 mg daily, divided into 3–4 doses. Clinical studies have used 3 g/day for 16 weeks with positive results.
- Neuroprotection: 1,050 mg daily (three 350 mg capsules of erinacine A-enriched extract), based on Alzheimer's disease research protocols.
- Acute Cognitive Enhancement: Single doses of 1,000–1,800 mg have been studied for immediate effects on cognition and mood.
Watch out for
- Common Side Effects: Generally well-tolerated. Mild stomach discomfort or digestive upset may occur at higher doses. Rare cases of skin rashes or itching.
- Allergic Reactions: Individuals with mushroom allergies should avoid Lion's Mane. Severe allergic reactions are rare but can include difficulty breathing.
- Blood Thinning: May slow blood clotting. Avoid combining with anticoagulant or antiplatelet medications without medical supervision.
- Diabetes Medications: May lower blood sugar levels. Monitor blood glucose closely if taking diabetes medications.
- Autoimmune Conditions: May increase immune system activity. Those with autoimmune diseases should avoid use or consult a healthcare provider.
