Niacin is converted to the coenzymes NAD and NADP, which help enzymes turn nutrients into energy and support normal cellular metabolism.
Caution: High amounts may cause flushing in some people and can affect liver enzymes; take with food and follow label directions.
Inositol serves as a component of cell signaling molecules that help regulate normal cellular communication and membrane function.
Caution: May affect blood sugar balance in sensitive individuals; monitor how you feel when starting.
Inositol hexanicotinate gradually releases niacin and inositol, allowing niacin’s coenzyme roles to occur with fewer flushing effects. The inositol component supports cell signaling while helping modulate the release of free niacin.
Label Warning: For adults only. Consult a physician if pregnant or nursing, taking medication, or have a medical condition such as liver problems, stomach ulcers, diabetes, or gout.
Who should be cautious: People with liver concerns, stomach ulcers, diabetes, or gout may need extra caution. Those on medications should discuss use with a healthcare provider before starting.

Niacin (Vitamin B-3) is an essential B-complex vitamin. Flush-free niacin contains inositol hexanicotinate, a form of niacin that consists of six molecules of niacin linked to a single inositol molecule. It is slowly broken down in the body to yield free niacin and inositol. This gradual release of niacin allows for true niacin activity without the characteristic niacin flush that many people cannot tolerate.
Inositol hexanicotinate is a stable, non-flushing source of niacin. This superior source of niacin works to reduce the common "niacin-flush" problems associated with high doses of niacin supplements.
This product has twice the niacin (500 mg per capsule) as in our regular strength product (250 mg per capsule).
Take 1 capsule daily as needed, with a meal.
