Think flush-free niacins are the right choice?

Get the facts:

  • Flush-free niacins may not cause flushing, but they also have not been clinically proven to support good cholesterol (HDL)1
  • Among the different forms of dietary supplement niacin (including flush-free niacin), only nicotinic acid, the key ingredient in SLO-NIACIN®, is clinically proven to support good cholesterol (HDL) within the normal range*1,2
  • SLO-NIACIN® Tablets have a unique polygel® system that ensures the gradual and measured release of nicotinic acid and is designed to reduce the incidence of flushing3

SLO-NIACIN® Tablets can help maintain good cholesterol (HDL) within the normal range.*2 With a unique polygel® controlled-release system, SLO-NIACIN® Tablets gradually deliver nicotinic acid into the body and are designed to help reduce the incidence of flushing that is sometimes associated with niacin use.


Do not use SLO-NIACIN® Tablets if you have a known sensitivity or allergy to niacin. Do not take niacin unless under your doctor's supervision if you have heart disease (particularly, recurrent chest pain or recent heart attack), gallbladder disease, gout, arterial bleeding, glaucoma, diabetes, impaired liver function, stomach ulcers, or are pregnant or lactating. Before taking 500 mg/day or more, call your doctor. If you are taking high blood pressure or cholesterol-lowering drugs, call your doctor before taking niacin due to possible interactions. Case reports of unexplained muscle-related complaints, including discomfort, weakness, or tenderness, have been documented with HMG-CoA Reductase Inhibitors in combination with niacin. Increased uric acid, glucose, and abnormal liver function tests have been reported in persons taking 500 mg/day or more. Discontinue use and call your doctor immediately if you experience persistent flu-like symptoms (nausea, vomiting, not feeling well), loss of appetite, decreased and dark-colored urine, muscle discomfort or weakness, irregular heartbeat or vision problems. Niacin may cause temporary flushing, itching and tingling, feelings of warmth and headache, particularly when beginning, increasing dosage, or changing brands.
