Garlic powder has all the benefits of whole garlic because it is a powdered version of whole garlic. Food-grade powdered garlic, available in most grocery stores, makes a nutritious addition to your diet, while garlic powder supplements — tested to contain a significant amount of beneficial compounds — are available at pharmacies and health food stores. Before taking garlic as a supplement or increasing your normal intake, be sure to discuss it with your doctor to discuss an appropriate type of supplement, as well as a safe dosage.
One study, published in “Lipids in Health and Disease” in 2010, found that garlic powder creates small reductions in total blood cholesterol and low-density lipoproteins, or “bad” cholesterol. Studies are still being conducted regarding garlic and its affect on high-density lipoproteins, or “good” cholesterol. Discuss adding garlic to your diet with your physician if your goal is to reduce your cholesterol levels.
