Who should not take nicotinamide?

Who should not take nicotinamide? This is a common question as the supplement becomes increasingly popular for its skin and cellular health benefits. While nicotinamide, a form of vitamin B3, is generally safe for most people, there are certain cases where caution or medical consultation is necessary before use.

People with liver disease or a history of liver issues should be especially careful. High doses of nicotinamide have been associated with elevated liver enzymes, and prolonged use may exacerbate pre-existing liver conditions. Always consult your doctor if you have any liver-related concerns.

Individuals with diabetes should also be cautious. Nicotinamide may influence blood sugar levels and insulin sensitivity. While some studies suggest potential benefits, others warn of possible interference with glucose regulation, making medical advice essential before starting supplementation.

Pregnant or breastfeeding women should avoid high doses unless specifically advised by a healthcare provider. Although nicotinamide is found in prenatal vitamins at safe levels, therapeutic doses should be supervised by a professional.

In rare cases, people may experience allergic reactions, gastrointestinal discomfort, or skin flushing. If you experience any unusual side effects, discontinue use and consult your doctor immediately.

While generally beneficial, nicotinamide isn’t right for everyone. Understanding Who should not take nicotinamide? is key to using it safely and effectively.
