Buying advice

When choosing an alpha lipoic acid supplement, consider the form: R-ALA (stabilized) is more bioavailable but costlier, while racemic ALA (R+S) is cheaper and still effective for general antioxidant support. Check potency per serving and look for third-party testing or GMP certification to ensure quality. If you have specific health goals like blood sugar control, R-ALA may be worth the extra cost. Always consult with a healthcare professional before starting new supplements.
