Amino acid supplement
Last reviewed June 2026
Who is this for?
Methionine is an amino acid (a building block of protein) that your body needs but cannot make on its own. It helps protect the liver, supports the body in removing toxins, and is used to make urine more acidic to prevent certain types of urinary tract problems.
Serves as a methyl donor in transmethylation reactions, supporting glutathione synthesis and hepatic detoxification pathways while promoting urinary acidification to inhibit bacterial adherence and crystal formation. Acts as a precursor for polyamine synthesis, facilitating cellular regeneration and supporting hepatoprotection against acetaminophen-induced toxicity through enhanced phase II conjugation capacity.

For adults, the usual dose is 250 mg capsules taken 1 to 2 capsules, 3 to 4 times daily depending on your doctor's instruction. You can take it with or without food, but taking it with food may reduce stomach upset.
If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take two doses at once to make up for it.
Always buy your Methionine 250 mg Capsules from a registered pharmacy — avoid roadside or unverified sellers. Do not use methionine as a substitute for proper medical treatment if you have liver or kidney problems. If you are taking it for urinary tract issues, drink plenty of water alongside it.
Levodopa (used for Parkinson's disease) — methionine may reduce its effectiveness. Paracetamol (Panadol) — methionine is sometimes used alongside it in overdose situations, but always follow doctor's advice. Avoid taking with other acidifying agents without your doctor's knowledge.
