The Divided Opinion on Amino Acid Supplements

L-carnitine supplements, derived from amino acids, are popular for their potential benefits in boosting energy, improving heart health, aiding weight loss, and supporting conditions like PCOS, especially for those with lower dietary intake such as vegans. While generally safe up to 2,000 mg daily, they may cause side effects like nausea or fishy odor, and are not recommended for everyone, particularly pregnant women or those on certain medications. Consulting a healthcare provider before starting supplementation is advised.
