Overview
•Magnesium at 150 mg per tablet (300 mg daily) is within safe limits for adults but may cause mild GI upset in sensitive individuals; heavy magnesium oxide has lower bioavailability.
•Feverfew extract (15 mg equiv. 150 mg leaf) may trigger oral ulcers or allergic reactions in Asteraceae-sensitive people; avoid if allergic to ragweed.
•Product contraindicated during pregnancy and breastfeeding due to potential uterine stimulant effects from cramp bark and feverfew; not suitable for children.
•Nicotinamide 20 mg and vitamin B5 18.3 mg are low doses with minimal side effect risk, but monitor for niacin flush at higher intakes.
•Rutin 250 mg is generally safe but may interact with blood thinners; contains sulfites, posing asthma exacerbation risk for sulfite-sensitive individuals.
•No major drug interactions for most ingredients, but feverfew may reduce effectiveness of blood clotting medications; consult healthcare provider if on anticoagulants.

Dosage & Bioavailability
How the active doses and forms in Nicotinamide, Magnesium, Feverfew Extract and Vitamin B5 compare to the research.
•Magnesium (as heavy Magnesium oxide) — 300 mg a day; within the 100-400 mg/day typically used in studies. The heavy magnesium oxide form is less well absorbed than others. This range is provisional until reviewed.
•Nicotinamide — 40 mg a day is over the 35 mg/day upper limit (IOM (NIH ODS)).
•Calcium pantothenate equiv. to Pantothenic acid (vitamin B5) — 40 mg a day; studies use 5-10 mg/day. Above studied amounts is not the same as unsafe.
