Se-100 - Selenium (100 vegetable capsules)
Product Overview
Se-100 is a pure, highly bioavailable selenium supplement providing 100 mcg of elemental selenium per capsule in the form of L-selenomethionine. This organic amino-acid form of selenium occurs naturally in foods and is recognised for superior absorption compared with inorganic salts such as sodium selenite or sodium selenate.
Selenium is an essential trace mineral required for the production of selenoproteins. These proteins support normal thyroid hormone metabolism and the activity of key antioxidant enzymes that help protect cells from oxidative stress.
Suggested use: Take one capsule daily, or as directed by a healthcare professional.
Free from: Dairy, egg, fish, shellfish, nuts, wheat, gluten, soy, sugar, yeast, artificial colours and preservatives. Suitable for most dietary preferences. Se-100 is suitable for vegetarians.
Key Information
Type of supplement
Essential trace mineral (selenium), supplied as the organic compound L-selenomethionine.
Half-life in the body
L-selenomethionine has a relatively long whole-body residence time. Once absorbed it can be incorporated into body proteins in place of methionine and is reutilised, giving an approximate whole-body half-life of around 250 days. Plasma levels rise within a few hours of intake and remain elevated longer than with inorganic forms.
Best time of day to take it
Selenium can be taken at any consistent time of day. Taking it with a meal is generally preferred: food supports absorption of the organic form and may reduce the chance of mild digestive discomfort. Many people find morning with breakfast convenient for routine.
Optimum dose
- The UK/EU Nutrient Reference Value and US Recommended Dietary Allowance for adults is 55 mcg selenium per day (slightly higher in pregnancy and lactation).
- Many people obtain adequate selenium from food (Brazil nuts, seafood, organ meats, grains, etc.).
- A 100 mcg supplemental dose is a common amount used when dietary intake is low or when higher status is desired under professional guidance.
- Total daily intake from food + supplements should remain well below the upper limit.
Long-term safety
Selenium is safe for long-term use when total daily intake stays within established limits. The US Tolerable Upper Intake Level is 400 mcg per day for adults; the European Food Safety Authority has more recently set a lower adult UL of 255 mcg per day.
Chronic excess can lead to selenosis, characterised by brittle hair and nails, skin changes, garlic-like breath odour, gastrointestinal upset, fatigue or neurological symptoms. Individuals with already high selenium status, those at risk of type 2 diabetes, or people taking multiple selenium-containing products should seek advice before supplementing. Regular monitoring of selenium status is advisable with prolonged higher-dose use.
Quality Notes
Se-100 uses L-selenomethionine, the form found in natural food sources, chosen for its high bioavailability. The product is manufactured to pharmaceutical-grade standards and is yeast-free.
