Every vendor on this page was checked on September 25, 2026 against its own website and the AKA's published vendor list. Prices, policies and AKA status change, so each review shows a last-verified date. If a vendor adds 7-OH products, drops off the AKA list or starts publishing batch COAs, its score changes under the same published method and the ranking above is updated.
Scores follow the method on our About page. Head-to-heads: Kats Botanicals vs Golden Monk, Golden Monk vs Happy Hippo, Kats Botanicals vs Happy Hippo.
The FDA has not approved kratom for any medical use and warns consumers not to use it. Kratom is banned in several states and some cities, and most vendors sell only to adults 21+.
