Nutritional Benefits of Garlic Powder
Garlic powder has a very strong flavor, so most recipes use it in moderation. In general, you'll find that most recipes that call for garlic powder use just a teaspoon or so.
However, there are exceptions. For instance, our recipe for Parmesan Garlic Fries goes heavy on the garlic powder, using 2 tablespoons of garlic as well as garlic salt.
Garlic is very rich in nutrients. However, you won't usually obtain large amounts of them from garlic powder, as it's usually consumed in such small quantities.
However, if you were to eat those Parmesan Garlic Fries, the USDA says that this recipes's garlic powder content would provide you with 64 calories, 14.1 grams of carbohydrates (1.7 grams come from dietary fiber) and 3.2 grams of protein. You'll also find the following nutrients in every 2 tablespoons of garlic powder:
- 6 percent of the daily value (DV) for iron

Despite the many potential health benefits of garlic, you shouldn't assume that garlic powder benefits are all the same. Garlic powder, which is produced as both a supplement and as a cooking spice, can vary substantially.
According to the Linus Pauling Institute, garlic powder supplements are processed in a way that focuses on garlic's beneficial sulfuric compounds. These sulfur-based bioactive compounds are one of the main components behind garlic powder's benefits. However, varied compounds are likely to be present in garlic powder supplements and seasonings since these products are created in different ways.
Additionally, some of garlic's beneficial bioactive compounds won't benefit you if you're consuming plain garlic powder. This is because those compounds tend to be degraded by your stomach acid.
If you're planning to consume powdered garlic and want to maximize its benefits on your health, try to consume garlic powder supplements with enteric coatings. Otherwise, fresh garlic's benefits are likely to be better than garlic powder benefits for your health.
