Selenium is an essential trace element (mineral) of fundamental importance to human health

Selenium is a micronutrient vital for many processes in the body. This includes maintaining a healthy immune system and plays an important role in normal thryoid hormone metabolism. Selenium also helps maintain male fertility, by promoting sperm motility.

Most soils in the UK and Europe are deficient in selenium, which translates in low-selenium of farmed food and eventually, low selenium status of populations who consume local food.

Selenium is an essential component of the key antioxidant enzyme glutathione peroxidase which works with other antioxidants to protect the cells of the body.

Selenium in the agricultural soil is inorganic. Once it gets absorbed by plants (and ends up in animals) it gets converted to organic selenium. The selenium we get from our diet can be bound to amino acids such as methionine and cystein.

In contrast, selenium in supplements can either be organic or inorganic. It is known that organic selenium compounds have an easier time getting absorbed in the body and incorporated in the different selenium-dependent enzymes and selenoproteins.

Pharma Nord Bio-SelenoPrecise
Our selenium supplement is a patented* selenium preparation containing the organic selenium yeast SelenoPrecise.

More than 40 scientific studies have been published having dealt with the quality, the stable 81% selenium content, the high level of bioavailability, and the safety of SelenoPrecise. This is what makes the preparation an extremely well-documented selenium source. Also, it is the main reason why SelenoPrecise is used in scientific studies and research projects worldwide.

Relative to the food we eat, the size of individual nutrients are actually incredibly small. As a result, we need to use units other than grammes (g) to describe them. Here's what the common units for nutrients are:

Grammes (G)- often used to describe nutritional powders. Most teaspoons of powder weigh approximately 5g.

Milligrams (Mg)- 1000mg is equal to 1g

Micrograms (Mcg or μg)- 1000μg is equal to 1mg

International Units (IU)- Slightly more complex than milligrams (mg) and micrograms (μg), International Units measure differently from nutrient to nutrient. The most common nutrients that are likely to be measured in IU are vitamins D, E and A.

  • Vitamin D: 1 IU is the equivalent of 0.025 μg of D2 or D3
  • Vitamin A: 1 IU is the equivalent of 0.3 mcg retinol
  • Beta-carotene (provitamin A): 1 IU is the equivalent of 0.6 μg of beta carotene
  • Vitamin E: 1 IU is the equivalent of 0.67 mg d-alpha-tocopherol

I have been using and recommended Pharma Nord's selenium for over 20 years now. It is without equal on the market in terms of quality and bio-availability.

The KiSel-10 study goes to show that you need to pick good products. My own grandchildren and my 96 year old uncle all use this product with impressive results.
