What is L-methionine?

L-methionine is an essential sulfur-containing amino acid and the precursor of SAM-e and cysteine.

It’s sold here as a pharmaceutical-grade research powder or in capsules.

What studies say about L-methionine

Methionine restriction extends lifespan in rodents, a well-known aging finding.

It’s a standard reagent, so it’s useful as a control or a defined input in nutrition and metabolism studies.

The original papers are on PubMed if you’d like to read them in full.

Working with loose L-methionine powder

Loose powder is the most flexible way to buy L-methionine. You can weigh any amount you need, dissolve it in your own solvent, or fill your own capsules. It’s also the cheapest format per milligram.

For small amounts you’ll want a scale that reads to at least 0.01g, and ideally 0.001g. Our digital scale and micro scoops make it easier to get consistent measurements. Weigh onto clean weighing paper, and close the bag or jar straight after so the powder doesn’t pick up moisture.

Making a solution from L-methionine powder

To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of L-methionine, dissolve it in about 25mL of solvent, then top up to exactly 30mL.

Check the compound’s solubility in your chosen solvent before you start, and try a small test amount first. Store the finished solution in a labelled glass bottle.

L-methionine quality and testing

Every batch of L-methionine is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.

Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.

How to store L-methionine

Keep it in a cool, dry place away from direct sunlight. Use a clean, dry scoop each time, and reseal the container straight away. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.

Common questions about the L-methionine powder

What can I dissolve L-methionine powder in?

That depends on the compound’s solubility and your protocol. Check the solubility data for your solvent first, and test a small amount before making up a full batch.

What scale do I need?

One that reads to 0.01g at minimum, and 0.001g for very small amounts. Our pocket scale reads to 0.01g.
