NordVital Wellness is an independent publication about supplements, cold and heat therapy and light therapy. Every guide is researched and written by the NordVital editorial team.
Who reviews our guides
We are not a medical practice. Our guides are not written or reviewed by physicians or registered dietitians, so they are educational and are not medical advice. Talk to your doctor before starting a supplement, especially if you are pregnant, take medication or have a health condition.
How we research a guide
- We start from the original studies and link to them, mostly on PubMed.
- Doses and safety limits are checked against official sources such as the NIH Office of Dietary Supplements and the European Food Safety Authority (EFSA).
- We do not lab-test products. For product picks we compare labels, doses, third-party certificates and manufacturer specifications.
- When the evidence changes, we update the guide and the date at the top.
Editorial Standards
Brands cannot pay for a better position. Some links earn us a commission (Amazon, iHerb, Life Extension and a few direct brand programs), and commission rates never decide our rankings. If you spot an error, contact us with a source and we will check it. See also our methodology and affiliate disclosure.
