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.

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 >> 

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.

2/23/2024

When Not to Take Selenium Cholesterol Lowering with Sterols/Stanols

A recent study using a popular supplement, CholestOff, showed a modest reduction in LDL ("bad") cholesterol and total cholesterol. The reductions were not as dramatic as in some other studies of sterols and stanols; possibly because participants in the study were already on a cholesterol-lowering diet. See the update to the Cholesterol-Lowering Supplements Review for details of the study, more information about the diet, and our tests of CholestOff and other cholesterol-lowering supplements. More >>

Concern Over Carnitine Causing Cardiovascular Disease

Intake of L-carnitine from supplements (and from red meat) may foster atherosclerosis (hardening of the arteries), according to new research. Once ingested, L-carnitine is converted in some people to a compound which reduces the normal clearing of cholesterol from arteries.

For more details, see the updated reviews of B Vitamin Supplements & Energy Drinks and Protein Powders, as some of these products contain L-carnitine. The Acetyl-L-Carnitine Supplements review has also been updated because acetyl-L-carnitine is chemically similar to L-carnitine, suggesting a potential concern.

Some Concern About Theobromine in Dark Chocolate

ConsumerLab's tests of dark chocolates show them to contain about as much theobromine (a caffeine-related stimulant) as heart-healthy flavanols. So is all this theobromine good or bad?

Get the details in the "Concerns and Cautions" section of the Cocoa Powders, Dark Chocolate, Extracts, Nibs, & Supplements Review, which includes comparisons of the amounts of theobromine in popular products, as well as amounts of flavanols, caffeine, and contaminants.

Can High-Dose Vitamin D Backfire?

Olive Oil Review Expanded: Many Do Not Make the Grade

We tested three new olive oils based on reader requests, and the results are in! Our new tests included two olive oils that claim to be high in polyphenols, and the results were surprising:

-- One olive oil was rated so poorly by our professional taster it was considered to be "lampante" -- i.e., not fit for human consumption.

-- The other high-polyphenol oil delivered a good amount of polyphenols, rated well for taste, and is now our new Top Pick for a very high-polyphenol olive oil.

We also tested California Olive Ranch Global Blend but were somewhat disappointed.

See the results now for 13 popular olive oils in our updated Extra Virgin Olive Oil Review.
