Vitamin B3 - Niacin
Niacin is a keystone B vitamin that does a little bit of everything. It’s fundamental in energy metabolism, protects against oxidative stress, balances blood lipids, and may play a role in longevity. It supports the brain, skin, and gut. Most people likely get enough from diet (with good sources being meat, fish, nutritional yeast, and sprouted or fermented seeds, grains, and legumes), though some groups are at risk for deficiency. High doses can be used to treat high lipid levels, though side effects are common at high doses. The best way to know how you are doing with niacin is to check your levels. What are yours?
