## Description

Selenium is an essential micronutrient. In the body, selenium gets incorporated into enzymes and other proteins to make vital compounds known as selenoproteins. These compounds promote cellular health. Se-Methyl L-Selenocysteine (SeMC) is an organic selenium compound that is more absorbable than the standard selenium that’s used in many supplements. Se-Methyl L-Selenocysteine from Life Extension contains 90 vegetarian capsules, enough for a 3-month supply. Non-GMO, gluten-free and manufactured in the USA.

## Features

- Healthy aging – High selenium levels are common among some of the world’s longest-living people. Se-Methyl L-Selenocysteine, a unique form of selenium, promotes healthy aging.
- Oxidative stress defense – Selenium is an important factor in protecting your body from oxidative stress because a group of powerful antioxidant enzymes need selenium to function.
- Highly absorbable – Se-Methyl L-Selenocysteine (SeMC) is a seleno-amino acid made by plants such as garlic and broccoli. In clinical studies, SeMC absorbs faster than standard selenium.
- Ingredients matter – We use only the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
- Live your healthiest life – We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
