How are we different?

Most nutritional supplements contain synthetic, inorganic forms of selenium. However, chemically organic selenium can be found in natural food products. The majority of dietary selenium comes in the form of selenomethionine. Selenomethionine has an absorption rate equal to approximately 90% and is better absorbed than inorganic forms. It can be stored in bodily proteins and therefore has a long retention time within the body.

Selenomethionine is a pure substance without unnecessary additives or hidden carrier materials. The filler, which is made of premium acacia fibre grown without pesticides, is the only additive. Our acacia fibre comes from sustainable, climate-neutral, resource-conserving and fair cultivation. This filler provides various nutrients and thus positively contributes to the overall benefits of this product.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass jars.

Selenium is a vital essential trace element and an integral component of more than 25 enzymes. It is involved in several important bodily functions including maintaining normal immune system function, protecting cells from oxidative damage, thyroid function and keeping hair and nails healthy.


Most selenium in natural food products comes in the form of selenomethionine. Selenomethionine has an absorption rate of approximately 90% and is better absorbed than inorganic forms.In the body, selenomethionine can be incorporated into proteins such as the amino acid methionine.

Health Benefits of Selenium According to the European Food Safety Authority (EFSA)

Selenium contributes to:

  • Protection of cells against oxidative stress
  • Normal function of the immune system (physical defense)
  • Normal thyroid function
  • Normal spermatogenesis (formation of sperm cells)
  • Maintenance of normal hair
  • Maintenance of normal nails


Recommended Dosage

Take 1 capsule (200µg selenium) daily with 200ml water.

Daily Requirements

To avoid developing a deficiency, the official daily requirement for selenium according to the German Nutrition Society (DGE) corresponds to 30µg-70µg (NRV: 55µg).


Due to its depot properties, selenomethionine can accumulate in the body. Closely monitor selenium blood levels during long term high dosages of this product. Selenomethionine can reduce histamine levels.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat.
