Our mission

We want to spread the word about the significant role of vitamin D in the prevention, management and also the treatment of serious diseases, including: arthritis, diabetes, multiple sclerosis, osteoporosis and many cancers.

Taking a vitamin D supplement is one of the most important things we can do to improve our health. It is the only vitamin we cannot get enough of from a healthy balanced diet. A lot of people don’t know that.

The large majority of people in Europe need to take vitamin D regularly because for five or six months of the year the sun is not strong enough to make any in our skin. It does not have to be our brand.

Of course, we believe that our D Microgels are the best, easy to swallow and great value. But what matters is that you get more vitamin D somehow. If you can’t get enough vitamin D from exposure to the sun, please take a supplement!


Our Goal

Help eradicate vitamin D deficiency (and insufficiency):

  • Increase awareness of the extent and consequences of vitamin D deficiency
  • Educate the public on the advantages of sensible exposure to the sun
  • Provide an affordable and reliable source of vitamin D3, the natural human form, for those who do not get enough sunshine
  • Fund clinical trials with vitamin D3 so that benefits may be better understood and get greater recognition from the authorities and doctors

Serious about Science 

 Nigel Rulewski

Dr Nigel Rulewski established the company The Vitamin D Company (Natural Products Corp) and this website over a decade ago in collaboration with Oliver Gillie who spent much of this life spreading the word about Vitamin D3. Sadly, Oliver passed away in May 2021.

Nigel is a physician with experience in multiple specialties, who spent over 25 years in the pharmaceutical industry as a chief medical officer gaining unusually broad drug development experience, ranging from identifying and assessing promising drugs to developing novel clinical positioning, designing and leading clinical trials, achieving FDA approvals, directing regulatory affairs, and supporting successful fundraising initiatives.

His interest in the utilization of Vitamin D3 led to the development of a micro-capsule formulation of Vitamin D3, available here.
