Tag: Methionine side effects

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.

Methionine is an essential amino acid, meaning the body cannot produce it, and it must be obtained from the diet. While generally safe when consumed in foods like meat, fish, and eggs, high-dose supplements of methionine carry specific risks and are not suitable for everyone and require a doctor's supervision.

According to research published in the journal *Molecular Neurodegeneration*, excessive methionine intake was shown to have neurotoxic effects and induce memory impairment in animal models. This highlights the complex safety profile of the essential amino acid L-methionine, which is vital for health in appropriate amounts but potentially harmful in excess.

According to research published in the journal Headache, high doses of the amino acid methionine may lead to neurological side effects, including headaches. While a vital nutrient, excessive intake, especially from supplements, could potentially trigger or exacerbate headaches in some sensitive individuals.
