Amazon's US Associates rate card puts Health & Personal Care at 1.00%. Supplements live there — the sports-nutrition aisle sits under the hpc node, and protein powder with it.
That is the number that circulates, and on its own it is misleading in three directions at once.
It is the floor, not the rate. Amazon Creator Connections lets a brand fund an additional commission that stacks on top of the base, with reported offers running 10–50%. A wellness creator promoting a participating supplement brand is not earning 1%. Anyone quoting 1% as what creators earn — including, very nearly, this page — is quoting the worst case as the case.
It is US-only. Amazon UK's fee statement puts Health & Personal Care at roughly 7%. A flat "Amazon pays 1%" is false for a British reader by a factor of seven.
Bounties dwarf it. The same card pays $25 for an Audible Premium Plus signup and $30 for Prime for Young Adults. One Audible signup outearns fifty $50 supplement sales.
What does survive is the shape of the thing. In April 2020 Amazon cut seventeen categories at once, and Health & Personal Care fell from 4.5% to 1% in that single change — a 78% cut to the base rate of the category wellness creators sell hardest. Furniture and Home went 8% to 3% in the same round. Across the decade to 2020 the average rate fell from about 9.25% to about 3.14%.
And the high rates sit where the content isn't. Luxury Beauty pays 10%. Amazon Games pays 20% — though that means Amazon's own published game titles, not video games, which pay 1% physical and 2% digital. The gaming creator reading this earns the same as the supplement creator.
