What is Selenium?
Selenium is an essential trace mineral. The body builds it into selenoproteins like glutathione peroxidase and thyroid hormone deiodinases.
Both too little and too much are harmful.

The SELECT trial reported in JAMA (2009) that selenium didn’t prevent prostate cancer.
It’s a standard reagent in redox research.

Powder or capsules: choosing your Selenium
This listing covers Selenium in more than one form. The loose powder is the flexible, lower-cost option if you’re weighing your own amounts. The capsules hold a fixed amount each, which saves time when every sample has to be the same.
If you pick the powder, a scale that reads to 0.01g or better is worth having. Our digital scale and micro scoops are made for this kind of work. Either way, keep the container closed tight so moisture stays out.
Making a solution from Selenium powder
To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of Selenium, 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.
Purity testing for Selenium
Every batch of Selenium 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 Selenium
Keep it in a cool, dry place away from direct sunlight. Use a clean, dry scoop for the powder, and keep both forms sealed between uses. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the Selenium powder and capsules
What can I dissolve Selenium 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.
