Selenium Methionine Capsules give you selenium in the form found in food, bound to the amino acid methionine as it is in Brazil nuts and grains. Each capsule provides 200mcg of selenium, which is 364% of the daily reference value. You take one a day with food. One pot holds 60 capsules, which is a 60 day supply.
Selenium is a trace mineral your thyroid and immune system both rely on, while intake from UK food is often below the reference value. The methionine form is stored in the body's proteins and released as needed, which is why it is the form used in most of the research and the usual choice for building a selenium store.
Selenium Methionine Capsules are most useful for:
For the form found in garlic, onions and broccoli, which is not stored the same way, choose Selenium SeMSC Capsules.
Each capsule provides 200mcg of selenium as selenium methionine, which is 364% of the daily reference value. The other ingredients are cellulose, calcium phosphate and the vegetable capsule shell. Selenomethionine and L-selenomethionine are other names for it.
Take one capsule a day with food. Keep to one a day and do not combine it with another selenium product, because selenium is a mineral where more is not better.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
How is selenium methionine different from SeMSC?
Selenium methionine is built into body proteins as a selenium store and is the form used in most research. Methylselenocysteine is not stored that way, because it is converted directly and cleared. Both give 200mcg of selenium per capsule, so you choose one or the other rather than both.
How much selenium should I take a day?
Take one capsule a day, which gives you 200mcg. Selenium is a mineral where more is not better, so do not add another selenium product on top.
When is the best time to take it?
With food, at any time of day. Taking it at the same meal each day makes it easy to remember.
Can I take it with a multivitamin?
Only if the multivitamin does not already carry a full selenium amount, because the two add up. Check the label before you combine them.
Does selenium have side effects?
Not at one capsule a day. Problems come from too much selenium over time, which is why the label amount is the limit.
Why capsules rather than tablets?
A capsule is a cellulose shell around the powder, so it needs none of the binders or coating that hold a tablet together.

Selenium Methionine provides an essential mineral supporting multiple body functions.
Take with food for best absorption. Be aware of interactions.
200 mcg, which is 364 percent of the reference value. Keep to one capsule a day.
Not if the multivitamin already carries a full selenium dose. Selenium is a mineral where more is not better.
People who want the store-building, most-researched form of selenium, and anyone who wants a single-ingredient capsule at a stated dose. 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 of the research. Methylselenocysteine (SeMSC) is not stored and is converted directly to methylselenol. Both give 200 mcg of selenium per capsule.
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.
