I take this form of Selenium supplement alongside my J. Crowe’s Lugol’s solution drops because the 2 elements work harmoniously together to support & nourish the thyroid, I chose this particular selenium due to the body’s ability to absorb it better than any other form of selenium, at a whopping 90% compared to 50%. Another thing I do that works well for me, since I don’t need more than 50-100mg of selenium at a time, is open up the capsules & divide each one up by pouring similar amounts of the 200mcg of the Se-Methyl L-Selenocysteine powder into a couple of empty gel caps I purchased separately, by doing so, I can get another 2 or 3 extra doses out of a 1 capsule dose & this not only gives me the corrected lesser amount I’m wanting, but also stretches the bottle out for a longer period of time, not only securing my health, since I don’t want too high a dose of selenium in my system at a time, but also saving me money in the long run, you just have to have the time, be meticulous & have a steady hand :)

Excellent

I’m taking this supplement for about a year, Life extension brand is only using high quality ingredients. This form of selenium mineral is very close to the one we get from food. SeML-SC encourages healthy cell function and division. Aid the protection of cells and tissues from oxidative damage. Promote immune function and health. Its benefits - most ingested selenium is converted into selenoproteins (i.e.,proteins that have a selenocysteine)—selenoproteins are a member of the selenol class of organoselenium compounds. The selenoproteins are needed for antioxidant enzymes (e.g., glutathione peroxidase). So, I would definitely recommend taking this one😊

I love this product because it helps you with increasing your testosterone levels and I haven't found any other brand that is making this kind of selenium. My only beef with the quality of the product is that it has microcrystalline cellulose but other than that its pretty good. The size of the packaging is well worth the price and the benefits you get for boosting your testosterone are immense.

Great!

Life Extension’s Se-Methyl L-Selenocysteine is a dietary supplement that provides a bioactive form of selenium, a trace mineral that plays a crucial role in supporting overall health, particularly in antioxidant defense, thyroid function, and immune health. This product is unique because it uses Se-Methyl L-Selenocysteine, a form of selenium that is more readily absorbed and utilized by the body compared to other forms, such as selenomethionine. 1. Antioxidant Support: Selenium is known for its antioxidant properties, which help protect cells from oxidative damage caused by free radicals. This can reduce the risk of chronic diseases and promote general wellness. 2. Supports Thyroid Health: Selenium plays a key role in the conversion of thyroid hormones, which are essential for regulating metabolism, energy levels, and overall hormonal balance. 3. Boosts Immune Function: Selenium is essential for optimal immune function, helping to enhance the body’s ability to fight off infections and illnesses. 4. Promotes Heart Health: There is some evidence to suggest that selenium helps protect against cardiovascular disease by reducing oxidative stress, improving blood vessel health, and supporting healthy cholesterol levels. 5. Bioavailability: The Se-Methyl L-Selenocysteine form is highly bioavailable, meaning it is efficiently absorbed and utilized by the body. This can potentially lead to better outcomes compared to other forms of selenium.
