Overview

•Niacin: 500 mg a day is over the 35 mg/day upper limit (ods.od.nih.gov) (about 14.3 times the limit). Suppie lowered this product's safety rating by one level for this reason.
•Active liver disease: high-dose nicotinic acid stresses hepatic tissue and can worsen liver damage
•Active peptic ulcer disease: nicotinic acid stimulates gastric acid production and can aggravate ulcers
•Active gout: high-dose niacin impairs uric acid clearance and can trigger acute flares
•At 500 mg, this serving substantially exceeds the EFSA (10 mg) and US (35 mg) daily upper limits for nicotinic acid.
•Stop and get advice if: severe dizziness, fainting, shortness of breath, or sudden severe joint pain
