Affiliate disclosure

Links from PerDose to retailers may be affiliate links. If you buy after following one, the retailer may pay us a commission. It costs you nothing extra.

It does not affect the ranking

• Tables are ordered purely by price per dose, calculated the same way for every product.
• Retailers and brands cannot pay for placement, and there are no sponsored or “featured” rows.
• Retailers that pay no commission are ranked exactly the same way as those that do.

The full method is on the how we compare page.
