Selenium SeMSC is selenium as methylselenocysteine, the form found in garlic, onions and broccoli. Unlike selenium methionine it is not stored in body proteins, so it is used more directly.
Selenium contributes to normal thyroid function, to the immune system, to the maintenance of normal hair and nails, and to the protection of cells from oxidative stress. Intake from UK food is often below the reference value.
Each capsule provides methylselenocysteine with cellulose and calcium phosphate, in a vegetable capsule suitable for vegans. It is often chosen by people who have been advised to take this particular form.
| Each capsule contains: | %NRV* | |

Selenium SeMSC provides an essential mineral supporting multiple body functions.
Take with food for best absorption. Be aware of interactions.
A blood test is the most reliable way to assess status.
Yes, many minerals affect medication absorption. Space supplements from medications by 2-4 hours.
People who want the methylselenocysteine form of selenium specifically, usually on a practitioner's suggestion, people already taking selenomethionine who want to alternate forms rather than combine them, and anyone who wants selenium from the form found in garlic, onions and broccoli rather than a yeast or inorganic source. Keep to one capsule a day and do not combine it with another selenium product.
Selenomethionine is built into body proteins as a selenium store and is the form used in most thyroid research. Methylselenocysteine is not stored that way; it is converted directly to methylselenol and cleared. Both give 200 mcg of selenium per capsule. Selenium contributes to normal thyroid function, normal immune function and the protection of cells from oxidative stress.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
