| Concern | Details | |---------|----------| | | No caffeine or other strong sympathomimetics, making it a safer option for those sensitive to caffeine. | | Huperzine A | At 200 µg it is within the typical safe range, but prolonged high‑dose use (> 1 mg/day) may cause nausea, dizziness, or cholinergic excess. Recommended cycling (e.g., 5 days on / 2 days off) is prudent. | | Bacopa | Can cause mild GI upset or dry mouth in sensitive individuals; best taken with food. | | Drug Interactions | • Anticholinergic meds (e.g., atropine, certain antihistamines) – may blunt efficacy. • Blood thinners (e.g., warfarin) – Bacopa and green‑tea catechins have mild antiplatelet activity; monitor INR if you’re on coumadin. • MAO‑I or SSRI antidepressants – Rhodiola can theoretically increase serotonin; caution advised. | | Pregnancy / Breastfeeding | Not enough safety data; manufacturer recommends avoiding use. | | Allergies | No common allergens (gluten, dairy, soy) listed, but check for cross‑contamination if you have severe sensitivities. |
