Niacin Time-release with NiaXtend provides niacin in an 8-hour extended-release form that may help avoid the uncomfortable skin flushing that commonly accompanies other forms of niacin. Approximately 200 coenzymes are comprised as niacin that play pivotal roles in metabolism and energy production within the body. Additionally, research suggests that niacin, in combination with a well-balanced diet, may help maintain healthy cholesterol levels that are already within the normal range.

Suggested Use

Take 1 tablet with food, one to two times daily, or as recommended by a nutritionally-informed physician.

Other Ingredients

Vegetable waxes (rice bran and/or carnauba wax), stearic acid, magnesium stearate (vegetable source), silica.


Caution: Temporary flushing, itching or warming of the skin may occur upon initial use. If you are under medical supervision, have liver dysfunction, gout, or are pregnant or nursing, consult your physician before taking this product.

No Flushing here

No flushing here, seems fine. However time will tell as to if its making any difference. No side effects. All OK.

A good vitamin, although on the packaging state that it is flush-free, I can still feel the flushing of my skin. But other than that it is good to have everyday.

Thanks for your feedback!
