                                Methionine is an essential amino acid, but excessive intake or supplementation can lead to a range of adverse effects on multiple organs, including the liver, brain, and cardiovascular system. As a precursor to homocysteine, too much methionine can disrupt delicate biochemical balances within the body, leading to potentially serious health issues.
