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.
Strengthen the Immune System
Garlic powder and whole garlic have been shown to strengthen the immune system and help fight cancer. The University of Maryland Medical Center says that, although longer trials need to be conducted, some studies suggest that people who have more garlic in their diet are less likely to develop certain types of cancer, particularly colon and stomach cancers. For patients who already have cancer -- or are going through chemotherapy -- garlic may help the immune system function more effectively and reduce the side effects of chemotherapy. Talk with your doctor about strengthening your immune system with garlic, along with its potential anti-cancer benefits.
Garlic powder and raw garlic have a blood-thinning benefit -- which can help people who suffer from high blood pressure and heart disease. The National Institutes of Health says the effects of garlic on platelet aggregation have been assessed in several human trials. However because garlic has been associated with several cases of bleeding, using this for blood-thinning benefits should be done with caution. Speak with your family physician regarding using garlic powder as a blood thinner.
