Niacin functions as a precursor to NAD and NADP coenzymes, which are central to energy metabolism and cellular redox reactions.
Caution: High doses may cause flushing or digestive discomfort in sensitive individuals, and those with liver concerns or gout should consult a healthcare professional due to potential effects on liver enzymes and uric acid.
Inositol acts as a component of cell membranes and signaling pathways that influence neurotransmission and metabolic processes.
Caution: May affect blood sugar regulation in some people, so those monitoring glucose should pay attention to how they feel.
Inositol hexanicotinate slowly releases niacin and inositol, providing niacin activity with reduced likelihood of flushing. Niacin supports cellular energy through NAD/NADP, while inositol contributes to membrane signaling, offering complementary roles in metabolic function.
Label Warning: For adults only. Consult a physician if you are 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.
Storage: Store in a cool, dry place after opening.
Reviewers commonly say they do not experience flushing and find the formula comfortable to take.
Users mention the capsules go down easily and have little to no taste.
Some comments suggest results vary, though many note positive effects like better daily energy.

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.
Take 1 capsule daily as needed, with a meal.
For adults only. Consult physician if pregnant/nursing, taking medication, or have a medical condition (liver problems, stomach ulcers, diabetes, gout, etc.). Keep out of reach of children.
Natural color variation may occur in this product.
Store in a cool, dry place after opening.
