Eden or Science & Co?
Eden is the cheaper way to start, at $129 a month against $141 for Science & Co, and since both charge one price whatever the dose, that gap of $12 holds all the way up. Judged by the headline prices you would pick Science & Co, advertised at $125 against Eden's $129, and that is the wrong way round once each bill is restated as a calendar month. Only Science & Co reaches District of Columbia, going by where each says it ships. Eden received an FDA warning letter in June 2026; Science & Co has none on record.

Where they actually differ
- They bill on different clocks. Eden charges every calendar month and Science & Co charges every 30 days. That alone changes what a “month” costs, which is the whole reason this index recomputes every price.
- What they advertise is not what they bill. Science & Co advertises $125 and bills $141.
How we know
Both figures were read on the seller’s own site and recomputed over a 30.4375-day calendar month from the charge and the billing period it covers. Neither is a seller’s own “/mo”. The full working for each — the charge, the period, the arithmetic and the date it was read — is on its own page: Eden and Science & Co. The method is set out in how we verify.
