Disclosure (affiliate & income)

This site plans to earn referral commissions from some product links in the future. Where it does, links will carry the sponsored attribute and will be labeled inside the article.

Independence of the grades

• Evidence grades are set from the literature, regardless of whether a product pays us.
• We will not raise a "D (weak evidence)" to a "B" because someone pays. Ingredients with weak evidence stay published as weak evidence — the magnesium-for-sleep page is the working example.
• Every recommendation page also lists options that pay nothing (such as improving your diet).
