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.

Latest Supplement Recommendations
New draft recommendations on vitamin and mineral supplement use were published this week by the U.S. Preventive Services Task Force. The recommendations apply only to healthy adults without nutritional deficiencies. They focus only on the use of supplements for the prevention of cardiovascular disease and cancer at doses not exceeding tolerable upper intake levels. The recommendations are based on existing science and are generally consistent with information already presented in ConsumerLab.com's Product Reviews. We have summarized the recommendations below, with links to more information in ConsumerLab.com's reports:
- Beta-Carotene and Vitamin E: Supplementation with either does not provide a benefit. Vitamin E does not pose a risk of harm, but beta-carotene increases the risk of lung cancer in people at risk for lung cancer.
- Other Single Vitamins, Minerals, Pairs, and Multivitamins: There is inadequate evidence regarding a benefit or a risk of harm.

Vitamin D Effect on Body Fat and Cholesterol
As we have reported earlier, adequate intake of vitamin D may decrease the risk of cardiovascular disease. A new study may help explain why. A 12-week course of vitamin D given to overweight women lead to a boost in HDL ("good" cholesterol) as well as a decrease in body fat. However, total body weight did not change and there was an increase in LDL ("bad") cholesterol, although it appeared to be less plaque-forming in nature. For details, including the dose given, see the updated information in the Vitamin D Supplement Review. More >>

Does Taking Vitamin D Reduce the Risk of Heart Disease?
Earlier research has suggested an association between higher vitamin D levels in the blood and reduced risk of heart attack. But blood levels are affected by both sun exposure as well as intake of vitamin D. A new study shows that men with higher vitamin D intakes from foods and supplements have a 14% reduction in their risk of cardiovascular disease and stroke. However, the study found no reduction among women. The amount of vitamin D intake shown to be beneficial and possible reasons why a benefit was not found in women are provided in the updated "What It Does" section of our Product Review of Vitamin D Supplements.
