It is a key component of selenoproteins like glutathione peroxidase, which help protect your cells from oxidative damage. Selenium also contributes to normal thyroid function, immune system performance, and cognitive function. Whilst you can get selenium from dietary sources such as Brazil nuts, tuna, sardines, eggs, and sunflower seeds, many people choose to supplement to ensure they meet their needs. A 200 mcg dose, as provided by this NOW Foods supplement, offers a convenient way to maintain optimal levels, especially for those with dietary restrictions or limited access to selenium-rich foods.\u003c\/p\u003e\u003cp\u003eSelenium works alongside vitamin E to neutralise free radicals, and its antioxidant properties are essential for long-term wellbeing. Because your body cannot produce selenium, it must be obtained through diet or supplementation.\u003c\/p\u003e\u003ch2\u003eHow Much Selenium Do You Need?\u003c\/h2\u003e\u003cp\u003eThe UK reference nutrient intake (RNI) for selenium is 60 mcg per day for adult men and 55 mcg for adult women. Pregnant and breastfeeding women require slightly more: 60 mcg and 70 mcg respectively. The safe upper limit is 400 mcg per day. With 200 mcg per capsule, this supplement provides a substantial but safe amount. However, if you regularly consume selenium-rich foods, consider your total intake. It is always advisable to consult a health care professional before starting any new supplement, especially if you take medication or have pre-existing health conditions. Selenium toxicity is rare but can occur at very high doses, so do not exceed the recommended serving.\u003c\/p\u003e\u003ch2\u003eKey Benefits of Selenium\u003c\/h2\u003e\u003ch3\u003eContributes to Normal Thyroid Function\u003c\/h3\u003e\u003cp\u003eThe thyroid gland contains the highest concentration of selenium in the body. Selenium is required for the conversion of thyroxine (T4) to the active triiodothyronine (T3) and helps protect the thyroid from oxidative damage. Adequate intake contributes to normal thyroid hormone production and metabolism.\u003c\/p\u003e\u003ch3\u003eContributes to Normal Immune System Function\u003c\/h3\u003e\u003cp\u003eSelenium supports the proper functioning of immune cells, including natural killer cells and macrophages. It helps regulate inflammation and supports the body's defence against infections. A well-functioning immune system relies on adequate selenium status.\u003c\/p\u003e\u003ch3\u003eContributes to Protection of Cells from Oxidative Stress\u003c\/h3\u003e\u003cp\u003eAs part of glutathione peroxidase, selenium helps neutralise harmful free radicals, reducing oxidative stress and supporting cellular health. This antioxidant activity is essential for protecting tissues throughout the body.\u003c\/p\u003e\u003ch3\u003eContributes to Normal Cognitive Function\u003c\/h3\u003e\u003cp\u003eSelenium's antioxidant properties extend to the brain, where it helps protect neurones from oxidative stress. Maintaining adequate selenium levels may support normal cognitive function as part of a healthy ageing process.\u003c\/p\u003e\u003ch3\u003eContributes to Maintenance of Normal Hair and Nails\u003c\/h3\u003e\u003cp\u003eSelenium is involved in the formation of selenoproteins that contribute to the health of hair and nails. Adequate intake helps maintain the structural integrity of these tissues.\u003c\/p\u003e\u003ch2\u003eChoosing the Right Selenium Supplement\u003c\/h2\u003e\u003cp\u003eNot all selenium supplements are created equal. The form of selenium matters for bioavailability and absorption. NOW Foods uses L-selenomethionine, a highly bio-available organic form that closely resembles the selenium found in foods. This form is efficiently incorporated into selenoproteins, making it a preferred choice for supplementation.\u003c\/p\u003e\u003cp\u003eThis product is non-GMO, gluten-free, and free from wheat, yeast, and other major allergens. It is also vegetarian and vegan-friendly, containing no animal-derived ingredients. Each vegetarian capsule delivers 200 mcg of selenium—a potent yet safe dose within the recommended range for adults. When choosing a supplement, look for third-party testing or certifications that ensure purity and potency. NOW Foods is a trusted brand known for quality control.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eCan I take selenium with other supplements?\u003c\/h3\u003e\u003cp\u003eYes, selenium pairs well with vitamin E and other antioxidants.
