About this item

THE LONGEVITY MINERAL – Selenium is a trace mineral that is essential for living a long, healthy life. Selenium promotes healthy immune function as well as heart and brain health. But what selenium is best known for its involvement in forming selenoproteins: powerful antioxidant enzymes your body uses to defend itself at the cellular level.
ANTIOXIDANT DEFENSE – Free radicals can take their toll on your health, whether you’re encountering them from your diet, the environment, or other factors. Selenium helps your body fight back at the cellular level.
MORE ABSORBABLE THAN OTHER SELENIUM FORMULAS – The selenocysteine in our formula is the specific form of selenium chiefly involved in thyroid, brain and metabolic health. Plus, it’s also easier to absorb than the inorganic selenium salts used in most supplements.
INGREDIENTS MATTER - Sourced using only the finest raw ingredients with the purity and potency your body deserves. This product is certified non-GMO and gluten-free. Manufactured in the USA and a Certificate of Analysis is available for every product we produce.
LIVE YOUR HEALTHIEST LIFE - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach and that rigorous scientific research is the path to get us there. Or formulations are created using the exact ingredients and dosages used in the studies that inspired them, ensuring that maximum bioavailability and efficacy is achieved.

Product Description

Selenium is an essential micronutrient for human health. In the body, it is incorporated into enzymes and other proteins to make vital compounds known as selenoproteins. Perhaps the best-known selenoprotein is the antioxidant enzyme glutathione peroxidase. Each molecule of glutathione peroxidase requires four selenocysteine units and catalyzes a reaction in which a free radical is scavenged by glutathione. By balancing cellular oxidation and reduction reactions, glutathione peroxidase and other selenoproteins protect cells and tissues from oxidative damage and support healthy cell function and cell division.

I take thyroid medication, but it's useless without being converted to it's active form, which requires both selenium and cystine for the enzyme to carry this out. I've been using the methionine form, but was curious when I came across this compound, if it would be more efficient. So far, so good.😆👍🏼

Taking supplements can expensive, but being healthy is worth the cost. I am not a doctor so I can't prescribe anything, but this substance is necessary for our bodies to fight off disease... most notably cancer. This product was not expensive and it does have a slight odor that I don't find objectionable as I feel that it indicates that it is indeed what it claims to be.
Do I feel healthier because of this product? That's hard to say as I've recently included other important substances in my diet, I do feel better than I have in years as I have fewer aches and pains.

Excellent For My Celiac, Hypothyroid Symptoms

Reviewed in the United States on October 1, 2016

Verified Purchase

If you are someone who has digestive health issues caused by Celiac or Crohn's disease, I trust you will find this product very helpful. As one who is intolerant to wheat accompanied by likely nutrient absorption issues, I find this highly bioavailable form of selenium to be an excellent safeguard against the pitfalls of deficiency. I was beginning to have several symptoms of hypothyroidism (constant lethargy, constipation, etc.), but after using this product for several weeks, I've noticed that my energy levels have risen, and several other symptoms have disappeared entirely. Love it!

Taking this as part of my transition into Bulletproof living. Have tossed out the multivitamins, and therefore needed a good source of selenium - a critical precursor for your antioxidants. This brand is a blend of many forms, which will ensure that the widest range of individual body chemistries will be able to absorb and incorporate it. Easy to swallow and small in size.

Excellent Selenium formulation

Se-Methyl L-Selenocysteine 200 mcg is an easily absorbable form on selenium. Good to take because, depending on farming methods, could be low to nonexisitant in foods.
