Also see our Top Picks for niacin and other B vitamin supplements.
 NAD+ and Cancer? (06/19/2019)
NAD+ and Cancer?
Supplements that raise NAD+ levels in the body have been promoted for anti-aging effects. But there is a theoretical risk that they could stimulate cancerous cells, and a CL member reported this week that a supplement containing such an ingredient, nicotinamide riboside, appeared to increase his PSA level. Learn more in the Niacin section of the B Vitamin Supplements Review.

2017 Niacinamide for Alzheimer's Disease? (09/19/2017)
Niacinamide for Alzheimer's Disease?
Niacinamide (a form of niacin) has been promoted as a way to protect against memory loss associated with Alzheimer's disease – a claim based on studies in mice. A recent study put this to the test in people. See the results in the "Niacin" section of the B Vitamin Supplements Review >>
 Niacin & Skin Cancer (04/19/2017)
Niacin & Skin Cancer
People who don't get enough niacin each day may be able to lower their risk of developing squamous cell skin cancer by getting a bit more niacin from their food or supplements suggests a recent analysis. However, this doesn't mean you should overdo it. For details, see the "Niacin" section of the B Vitamin Supplements Review. You can also find foods high in niacin using the food table in the report.
2016 Niagen Form of Niacin May Cause Flushing (10/11/2016)
Niagen Form of Niacin May Cause Flushing
Niacin is known to cause flushing (redness) and skin tingling at moderate doses. Other forms of niacin are said cause less flushing. One of these is Niagen. However, results of a recently published study suggest that it can cause flushing and "hotness" after just a single dose. More details are in the "Niacin" section of the B Vitamin Supplements Review >>
2015 Niacin Helps Prevent Skin Cancers (10/24/2015)
Niacin Helps Prevent Skin Cancers

 Niacin Reduces Skin Cancer (05/16/2015)
Niacin Reduces Skin Cancer
A recent study suggests that high-dose niacin (vitamin B-3) may reduce the risk of developing certain types of skin cancer. A closer look at the study, however, raises questions about its relevance to people in North America. Get the details, as well as more information about niacin and our product test results & comparisons, in the B Vitamin Supplements Review >> 
2014 High-Dose Niacin with Statins Not Worth It (07/19/2014)
High-Dose Niacin with Statins Not Worth It
Further evidence was published this week showing that the addition of high-dose niacin (vitamin B-3) to cholesterol-lowering treatment with statin drugs provides no worthwhile benefit and appears to increase the risk of adverse side events. For details, see the Review of B Vitamin Supplements and Energy Drinks >> 
2013 B Vitamin Supplements for Stroke? (09/21/2013)
B Vitamin Supplements for Stroke?
A review of 14 clinical studies suggests that B vitamins may help prevent stroke. However, a deep reading of the report shows the benefit to be slight, at best.  For details about the study, other uses of B vitamins (including B6, B-12, folic acid, niacin and complexes), and tests of these supplements, see the B Vitamin Supplements Review>>  
 Concern Over Niacin (03/17/2013)
Concern Over Niacin
You may have heard that a recent study suggests that supplementing with niacin at high doses does more harm than good. This appears to be true in only certain situations. Get the facts in the update to the B Vitamin Supplements Review >>
2011 No Benefit of Niacin with Statins (11/20/2011)
No Benefit of Niacin with Statins
According to a recently published study, high dose niacin added to statin drug treatment does not further reduce the risk of heart attacks and stroke despite improvements in levels of HDL cholesterol and triglycerides. In fact, there was a small increase in strokes among those taking niacin. However, a role remains for high dose niacin in lipid treatment. For details, see the update to the B Vitamin Supplements Review.
 Niacin Concern Stops Cardiovascular Study (05/31/2011)
Niacin Concern Stops Cardiovascular Study
A clinical trial using high dose niacin (vitamin B3) was recently stopped by the National Institutes of Health due to lack of benefit and a small increase in strokes. Patients in the study had cardiovascular disease and were already taking a statin drug to keep LDL ("bad") cholesterol levels low. The addition of high dose niacin was intended to increase HDL ("good") cholesterol, reduce elevated triglycerides, and, most importantly, reduce the risk of heart attacks and stoke. For more information, including the amount and type of niacin used in the study and additional information about niacin and niacin supplements, see the B Vitamin Supplements ReviewMore >>
