Selenium 200µg — 120 Capsules — Selenomethionine
Selenium is an essential trace mineral that your body cannot produce on its own. It has a well-documented role across several key biological processes — and with selenium contributing to the normal function of the immune system, normal thyroid function, and the protection of cells from oxidative stress, this is a nutrient worth getting right. This formulation delivers 200µg as selenomethionine — the naturally occurring form found in plant and animal proteins.

More Than a Basic Selenium Supplement
Not all selenium supplements are the same. The form of selenium matters. Inorganic forms — selenite and selenate — are absorbed differently to selenomethionine, the organically bound form that occurs naturally in Brazil nuts, grains and animal proteins. Selenomethionine is the form used in this formulation. The capsule is HPMC throughout, and the formula contains no Magnesium Stearate or Silicon Dioxide — both common flow agents omitted here to keep the product as clean as possible.
Making It Part of Your Daily Routine
One capsule a day, taken with food. Selenium fits quietly into any existing supplement routine — a morning capsule with breakfast or alongside other daily supplements works well for most people. At four months per bottle, stock management is straightforward.
Selenium in Nutritional Science
Selenium functions as a cofactor for a family of selenoprotein enzymes — molecules involved in thyroid hormone metabolism, antioxidant defence and several other processes in the body. The GB nutrition register recognises six well-established health effects for selenium, spanning immunity, thyroid function, antioxidant protection, and reproductive health. Selenomethionine is the form most consistently found in dietary selenium research.
Inside the Formula
Selenium 200µg (as Selenomethionine) — 364% of the NRV. Selenium contributes to normal spermatogenesis alongside its well-established roles in thyroid, immune and antioxidant function. Selenomethionine is the amino acid-bound form naturally present in selenium-rich foods.

Frequently Asked Questions
What form of selenium does this product contain?
Selenomethionine — the amino acid-bound form naturally present in plant and animal proteins, and the form used in the majority of dietary selenium research.
Why 200µg? Is that safe?
The EU/UK safe upper limit for selenium intake is 300µg per day from all sources combined, so 200µg from supplementation is within established safety guidance when dietary intake is considered. The tolerable upper intake level from the European Food Safety Authority is 300µg per day. As with any supplement, do not exceed the recommended intake.
Does this product contain allergens?
The Brown Rice Flour carrier in this formulation is processed with soy. If you have a soy allergy, consult your healthcare provider before use.
Is this product suitable for vegans?
Yes. The capsule shell is HPMC (hydroxypropyl methylcellulose) — a plant-derived material. The formula contains no animal-derived ingredients.
Can I take selenium alongside other supplements?
Selenium can be taken alongside most standard supplements. If you are taking thyroid medication or other medications affecting the thyroid or immune system, consult your GP before adding selenium to your routine.
