Does l-glutamine expire

Answer 1

L-glutamine, like many dietary supplements, does have an expiration date, which is typically printed on the packaging. While the compound may not become harmful after that date, its potency and effectiveness can diminish over time. For best results, it's advisable to use it before the expiration date and store it in a cool, dry place to maintain its stability. If it looks or smells off, it's best to discard it.
