Kyolic Aged Garlic Extract is in a class of its own. Unlike ordinary garlic supplements that can cause digestive upset and odor, Kyolic uses a unique cold-aging process developed over 60 years ago to convert raw garlic into a gentle, odor-free extract that is vastly more bioavailable. The aging process creates beneficial compounds — S-allylcysteine and S-allylmercaptocysteine — not found in ordinary garlic, which support cardiovascular health, immune function, and energy. Kyolic is backed by over 850 peer-reviewed scientific studies, making it one of the most thoroughly researched garlic supplements on the market. Cold-aged, odorless, and extraordinary in effect.
