NOW Foods Niacin 500 mg Flush-Free (90 & 180 vegetarian capsules) contains double the amount of niacin (vitamin B3) per capsule compared to the regular variant. This supplement contains inositol hexanicotinate, a form of vitamin B3 that is broken down slowly in the body. This form is suitable for people who are sensitive to the typical ‘flush’ effect of niacin supplements. With 500 mg per capsule, this is a high-dosed supplement of vitamin B3.
A "flush-free formula" means that the supplement contains vitamin B3 in a form that does not cause a "flush." Flush is the warmth and redness of the skin that some people experience with ordinary vitamin B3 in the form of niacin.
Yes, this is considered a high dosage of vitamin B3. It is well above the RDA, but below the acceptable upper limit. Consult a doctor or therapist for advice or prolonged use.
This supplement is suitable for adults who want to use niacin without the typical feeling of warmth from standard niacin.
