Selenium
The selenium from Greatlife is the best selenium we have found. It is a high-quality, easily absorbed form of selenium that helps support the immune system, protect cells against oxidative stress, and maintain healthy thyroid function. Selenium is also important for normal energy metabolism and contributes to fertility and reproduction. It is gentle on the stomach and has high bioavailability, making it an excellent choice for all ages. This supplement is pure, free from additives, toxins, and GMOs.
Selenium supports the normal function of the immune system, normal energy metabolism, and protects cells from oxidative stress. It helps maintain normal thyroid function and plays an essential role in the body’s antioxidant defense. If you are not getting enough selenium from your diet, a supplement may be necessary.
The selenium in Greatlife's supplement is in the form of selenomethionine. It is an organic form of selenium, where selenium is bound to the amino acid methionine. This form is considered one of the most bioavailable and easily absorbed sources of selenium, meaning that the body can effectively absorb and utilize selenium from selenomethionine.
Benefits of Selenomethionine
- High bioavailability: Selenomethionine is better absorbed by the body than other forms of selenium, making it a great choice for those looking to optimize their intake of this mineral.
- Supports the immune system: Selenomethionine plays a vital role in supporting a normal immune system and protecting cells against oxidative stress.
- Thyroid function: Selenomethionine is also important for maintaining normal thyroid function, as selenium is an essential component in the production of thyroid hormones.
- Antioxidant properties: Selenium is a powerful antioxidant that helps protect cells from damage caused by free radicals, which can help reduce the effects of aging and the risk of chronic diseases.
- Because selenomethionine is an organic form of selenium, it is considered more effective than inorganic selenium forms, such as sodium selenite or sodium selenate, in raising selenium levels in the body.
- Selenomethionine is also gentle on the stomach and can be used by individuals who are sensitive to other forms of selenium.
Better Absorption
Selenomethionine is effectively absorbed by the body and has high bioavailability, making it a great choice for anyone looking to maximize their selenium intake.
Selenium SELECT®
The selenium in Greatlife's selenium supplement comes from Selenium SELECT®. Common "chelated" and "organically bound" selenium is not the same as Selenium SELECT®, as these forms release inorganic selenium in the body. Selenium SELECT® is a unique, single chemical compound where selenium is molecularly integrated into methionine instead of sulfur. This allows it to be directly absorbed by proteins in the body through the same metabolic processes as methionine.
Benefits of Selenium SELECT®:
- High safety and bioavailability: It has better absorption and safety compared to traditional mixtures of selenium and methionine.
- Supports the body’s detoxification processes: The organically bound form of selenium in Selenium SELECT® plays an important role in the body’s natural detox processes.
- Natural L-(+)-form of selenomethionine: This form is crucial for effectiveness, as amino acids in living cells primarily occur in the L-(+)-form.
Selenium SELECT® contains the biologically active L-(+)-form of selenomethionine. This distinguishes the product from others that simply mix inorganic selenium salts with methionine. Thanks to its high safety and scientifically proven superior bioavailability, Selenium SELECT® is the preferred form of selenium for selenium supplements.

Why is selenium important for the body?
Selenium is an essential trace element that plays a central role in the body's antioxidant defense, immune system, metabolism, and reproductive ability. It is part of a group of enzymes called selenoproteins, including glutathione peroxidase and thioredoxin reductase, which protect cells against oxidative stress and damage caused by free radicals. Selenium is also necessary for normal thyroid function, as it is involved in the conversion of the inactive hormone T4 to the active T3.
What are the signs of selenium deficiency?
Selenium deficiency is more common in Europe than in many other parts of the world because the soils here contain little selenium. Common signs of deficiency may include fatigue, reduced immune function, hair loss, weak nails, impaired fertility, and decreased thyroid function. Long-term deficiency has been linked in some studies to an increased risk of cardiovascular problems, cognitive decline, and impaired cell function.
What role does selenium play in the immune system and antioxidant protection?
Selenium contributes to the normal function of the immune system and helps the body defend against infections and oxidative stress. It enhances the activity of white blood cells and protects cell membranes from damage. Research shows that adequate selenium levels contribute to shorter illness duration and better resistance to viral infections, while also protecting cells from premature aging through its antioxidant effect.
How does selenium affect the thyroid?
Selenium is necessary for the thyroid to function normally as it is part of the enzymes that convert thyroxine (T4) into triiodothyronine (T3), the active form of thyroid hormone. Selenium also protects thyroid tissue from oxidative damage that can occur in autoimmune conditions, such as Hashimoto's thyroiditis. A deficiency in selenium can therefore contribute to fatigue, weight gain, coldness, and hormonal imbalance.
Why is L-selenomethionine used in dietary supplements?
L-selenomethionine is the naturally occurring organic form of selenium that the body can absorb most efficiently. This form is stored in the body's tissues and used as needed, providing a stable and consistent selenium uptake over time. Greatlife uses the patented form Selenium SELECT®, which is clinically documented and standardized for optimal bioavailability and safety. It is better absorbed than inorganic forms such as sodium selenite and is also gentle on the stomach.
How much selenium does the body need daily?
The daily reference intake (DRI) for adults is 55 micrograms per day, but optimal levels may be slightly higher depending on individual needs, stress levels, and dietary habits. One capsule of Greatlife Selen SELECT® contains 100 micrograms of selenium, which corresponds to 182% of the DRI, a safe and effective dose to support the immune system, thyroid function, and antioxidant protection.
Can you get too much selenium?
Selenium is a trace element that is needed in small amounts, but excess should be avoided. The dose in Greatlife Selen SELECT® is well within the safe range for long-term use. Toxic effects occur only at very high intakes, usually over 800–900 micrograms per day for extended periods, which is far above the amount found in a high-quality supplement.
When and how should Selen SELECT® be taken?
The recommended dose is 1 capsule daily with a meal, preferably in the morning. Since selenium interacts with other nutrients, such as zinc and vitamin E, it can be beneficial to take it as part of a balanced nutritional routine. If there are difficulties swallowing, the capsule can be opened and the contents mixed into food or drink.
Who can benefit from a selenium supplement?
Selen SELECT® may be particularly valuable for individuals looking to strengthen their immune system, support thyroid function, protect the body against oxidative stress, or promote fertility and cell health. It can also be beneficial for those living in areas with selenium-deficient soils, following a vegetarian diet, or having low intakes of fish and seafood, which are typically the main dietary sources of selenium.
