I wouldn't take any other selenium product, Pharma Nord selenium products are the best in the world and having read the literature, SelenoPrecise is a product I trust. Thanks Pharma Nord for the research you put into your products.
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.
