Niacin Flush: Why Some Supplements Make Your Skin Warm
Niacin (vitamin B3) can cause a brief warm, red skin flush. Learn why it happens, how long it lasts and when to talk to a doctor.
If you have ever taken a supplement and felt your face and chest go warm and pink, niacin was probably the reason. Nitric Boost Ultra lists niacin (vitamin B3), so here is what to know.
What niacin does
Niacin is one of the B vitamins. It is essential for normal energy metabolism, helping your cells turn food into usable energy. You get it from meat, fish, whole grains, peanuts and fortified foods.
What the flush is
Certain forms of niacin cause small blood vessels near the skin to widen temporarily. This can cause:
- Warmth or redness, usually on the face, neck and chest
- A mild tingling or itching feeling
It usually starts within about 15 to 30 minutes and fades within an hour or so. For most people it is uncomfortable rather than harmful, and many find it lessens with regular use.
Tips that may help
- Take your serving with food rather than on an empty stomach.
- Avoid hot drinks and alcohol around the time you take it.
- Stay consistent, since flushing often eases over time.
When to get help: if you have dizziness, a racing heart, swelling, trouble breathing or a severe rash, stop taking the product and seek medical help. People with liver disease, gout, diabetes or stomach ulcers should talk to a doctor before taking niacin supplements.
The bottom line
Niacin flush is a well-known, usually harmless reaction. Knowing what it is means it won't take you by surprise. Follow the directions on your jar. Read the safety FAQ or see how to take Nitric Boost Ultra.
