An essential trace mineral that supports thyroid health, optimal immune function, and healthy aging*
Selenium supports the body’s natural antioxidant capabilities and promotes healthy endocrine and immune function, with benefits for cellular energy levels, metabolism, mood, and healthy hair and skin.
Selenium is an important trace mineral and an essential nutrient that your body needs. Low levels of selenium can impact the heart, joints, eyes, and the immune, endocrine, and reproductive systems. Because the body cannot make selenium on its own, selenium must come from the diet or supplementation.
Thorne uses one of the most bioavailable forms of selenium – L-selenomethionine – to help the body maintain an optimal selenium level. Supplementing selenium supports normal cell function and differentiation, and healthy heart, connective tissue, eye, liver, and thyroid function.*
Benefits of Thorne’s Selenium
- Supports healthy thyroid function, which benefits energy levels, metabolism, mood, and healthy hair and skin*
- Supports the conversion of T4 thyroid hormone (thyroxine) to active T3 (triiodothyronine)*
- Supports healthy aging with antioxidant benefits throughout the body to promote healthy skin, hair, and cognitive function*
- Acts as a cofactor for numerous enzymes in the body including the important glutathione and superoxide dismutase systems*
- Protects the body and brain from the effects of excess free radicals from environmental toxins, stress, and poor diet and lifestyle choices*
- Promotes optimal immune function*

What is Thorne Selenium?
It's a single-ingredient mineral supplement providing 200 mcg of selenium per capsule in the form of L-selenomethionine, an amino-acid-bound form of selenium chosen for its absorption.
What does selenium do in the body?
Selenium is an essential trace mineral incorporated into selenoproteins such as glutathione peroxidase and superoxide dismutase (antioxidant enzymes) and thyroid deiodinases, which convert inactive thyroid hormone (T4) into its active form (T3). This supports antioxidant defenses, healthy thyroid function, immune function, and normal cell development.
Why is selenomethionine used instead of other forms of selenium (like sodium selenite)?
Selenomethionine is an organic, amino-acid-bound form that is generally well absorbed and well tolerated compared to inorganic forms.
What's the suggested dose?
Take 1 capsule daily, or as recommended by a healthcare practitioner. Some product listings note that taking it with food may be more comfortable for certain individuals.
How much of the Daily Value does one capsule provide?
200 mcg of selenium provides about 364% of the Daily Value.
Who might benefit from taking this product?
It's generally positioned for adults with low dietary selenium intake, or those seeking general antioxidant and thyroid support. As with any supplement, it's worth discussing individual needs with a healthcare provider.
What are the other ingredients (fillers, binders, etc.)?
Just microcrystalline cellulose and a hypromellose (plant-derived) capsule. Thorne's products are formulated without magnesium stearate or other common binders/fillers.
Is it free of common allergens?
Yes, it's free of gluten, dairy, soy, eggs, tree nuts, peanuts, fish, shellfish, corn, and yeast, and contains no GMOs or artificial preservatives.
Is it third-party tested/certified?
Yes, it's NSF Certified for Sport / NSF Contents Certified, meaning it's tested for label accuracy and banned substances, which is why it's used by many professional sports teams and organizations.
Are there any precautions or side effects to be aware of?
High selenium intake can cause unwanted effects such as hair or nail changes, so it's important not to exceed the suggested use. People who already get significant selenium from diet (e.g., Brazil nuts, seafood) should be cautious about additive intake. Anyone with a known hypersensitivity to the ingredients shouldn't use it, and it's advisable to consult a healthcare professional before use if pregnant, nursing, or managing a medical condition.
Can it help protect against heavy metals?
Some sources note selenium supplementation may exert a protective effect against toxic heavy metals like mercury and cadmium, though this is a supportive/adjunctive role rather than a treatment.
How should it be stored?
Store tightly sealed in a cool, dry place; use only if the tamper-evident seal is intact.
Is this a doctor-formulated or clinically backed product?
Thorne is a science-based supplement company founded in 1984, and its products (including this one) are widely used and dispensed by healthcare practitioners.
