Methionine
What is methionine?
Methionine is an essential amino acid, so your body can't make it and it has to come from your diet. You'll usually get it from protein foods like meat, fish or eggs.

Is Methionine right for you?
Common questions
Is methionine the same thing as SAMe?
No, even though the names sound related. SAMe (S-adenosylmethionine) is a different substance with its own separate listing under Australian rules. This page covers plain methionine, the free amino acid, which is a permitted ingredient in its own right. If it's SAMe you're after, ask us, as that's a different product.
Is methionine regulated as a medicine in Australia?
Methionine, the free amino acid, is a permitted ingredient in listed medicines (item 3283 on Australia's permitted ingredients list), with no dose cap or warning statement attached. No permitted health claim specific to methionine has been confirmed yet, so there's no set wording for what a product can say it does. It's also an everyday amino acid in food, so it can appear in foods with no medicine listing at all.
