Affiliate Disclosure

SUPX is free to use. We help pay for it by earning commissions when you buy through some of our links.

We link to the best option we find for quality and price, even when we earn nothing from it. Many of our links pay us nothing at all. When you click a link to Amazon or another seller and make a purchase, we may receive a commission. You pay the same price either way.

As an Amazon Associate we earn from qualifying purchases.

We also participate in affiliate programs run by other retailers, supplement brands, and affiliate networks.

Commissions never affect how we rank or describe supplements or products. Research summaries, quality information, and rankings are produced the same way whether or not we earn a commission.
