Affiliate policy
Last updated 20 October 2026
As an Amazon Associate, @ohdarlingitsbiology earns from qualifying purchases, at no extra cost to you.
- Affiliate links appear only on the supplement library page at the moment. Each one is labelled "Affiliate link".
- Affiliate links are never the main reason a page exists, and they never decide what we write.
- We don't accept payment from brands to feature a product.
- Listing a product isn't a recommendation to take it. Talk to your GP or pharmacist first, especially if you take prescribed medicines.
- Prices shown are approximate and can change. Check the listing for the current price.
