Niacin

Niacin, also known as vitamin B3, is part of the B-complex family. It is a water-soluble nutrient. Vitamin B3 supports healthy brain function, mood regulation, cellular function, and blood flow.^†

Niacin (B3) supports vasodilation, which helps blood vessels relax.^†

 

If you take niacin supplements on an empty stomach, you could experience short-term side effects such as a flushed appearance or feelings of warmness or tingling because of these small blood vessels dilating. This common effect of niacin is referred to as niacin flushing.

 

This harmless response normally dissipates within an hour. It is related to niacin's role in vasodilation (widening of blood vessels). Vasodilation leads to better circulation, capillary flushing, and increased blood flow to the surface of the skin. To minimize or prevent niacin flushing, consider taking vitamin B3 supplements with food or in divided doses.

 

You can find niacin in foods like meat, poultry, seafood, nuts, and bananas. It is also available in dietary supplements. Niacin must come from the diet or niacin supplements since your body cannot make it.

 

Seeking Health’s Niacin capsules provide 50 mg of niacin as nicotinic acid.

 

Niacin is a building block of tryptophan, which helps the brain make the neurotransmitter serotonin. Niacin and other B vitamins are necessary for a healthy nervous system and mood balance.^†
