Suggested use: As a dietary supplement, take 200 mg (about 1/10 tsp) once daily, or as directed by a physician. Use an accurate milligram scale to measure. R-ALA has a low melting temperature that may cause your product to clump together. No loss of potency or efficacy occurs if it melts, but it may become a semi-solid rubbery mass. R-ALA may also have an unpleasant chemical flavor. This is normal and does not affect the quality of the product.
