Alpha Lipoic Acid (ALA) is an antioxidant that plays a vital role in the body. It helps to protect cells from damage caused by free radicals, which are molecules that can cause oxidative stress and lead to cell death. ALA also helps to convert glucose into energy, which is essential for proper functioning of the body. Additionally, ALA has been shown to reduce inflammation, improve insulin sensitivity, and protect against certain types of cancer. ALA supplements may be beneficial for those who are deficient in this nutrient or who want to increase their intake of it.
