HDL, which stands for high-density lipoprotein, is also known as the "good" form of cholesterol. Cholesterol is packaged into different kinds of lipoproteins by the liver. High-density lipoproteins are linked with a reduced risk of atherosclerosis and cardiovascular disease. Raising HDL levels is one way many people can protect their hearts. Although many supplements can increase HDL levels, patients should still talk to their doctors about their cholesterol levels as there is not enough evidence to support their use in treating cardiovascular disease.
Niacin
Of the supplements and medications commonly recommended by doctors to treat cholesterol problems, niacin is the most effective at raising HDL levels, MayoClinic.com reports. Niacin can be obtained over-the-counter or via a prescription. Both forms are theoretically equally effective, though there is less regulation and quality control of the over-the-counter forms. When taken regularly, niacin is able to increase HDL levels by between 15 and 35 percent. Niacin can also be found in many foods, including lean meats, dairy products, nuts, eggs and enriched breads and cereals. Because niacin can cause liver damage and other serious side effects when taken in high doses, patients should talk with their doctors before taking niacin supplements.
Omega-3 Fatty Acids
Omega-3 fatty acids are another type of supplement which can be used to raise HDL levels. Interest in these lipids began when it was noted that Eskimos and people who consume a Mediterranean diet typically have higher HDL levels and a lower risk of heart disease, the University of Maryland Medical Center explains. Both of these types of diets include foods which are rich in omega-3 fatty acids. Foods high in these fatty acids include walnuts, soy protein, canola oil, flaxseed and fatty fish such as cod, mackerel and herring. Fish oil supplements are often taken due to their high levels of omega-3 fatty acids. In addition to their effects on HDL levels, omega-3 fatty acids are sometimes used to treat or prevent diabetes, rheumatoid arthritis and lupus.
Chromium
Chromium is often touted as a supplement for weight loss, despite the fact that it has not been proven to be effective, InteliHealth states. On the other hand, chromium can be beneficial for people looking to raise their HDL levels. As InteliHealth explains, one study found that regular supplementation with a form of chromium increased HDL levels by 16 percent, though other studies have generated mixed results. Although chromium can be purchased in supplement form, many foods, such as whole grains, peanuts, legumes and brewer's yeast also contain chromium.
