Aeternum: longevity supplements, skincare kits and test kits in dollars

Shopping at Aeternum? See all current Aeternum discount codes and deals, checked regularly.

Aeternum (the name is Latin for "forever") is an online store built around what it calls longevity formulas: capsules and powders such as NMN, fisetin, marine elastin and GlyNAC, a Silver Reverse range for gray hair, a small skincare line and an at-home DNA test kit. The US version of the site prices everything in dollars, and the company says it holds stock in the USA as well as the UK, Europe, Canada, Australia, Hong Kong and Japan, so US orders ship from local stock. It suits shoppers who already know which ingredients they want and like to buy in bundles.

The site says every batch is third-party tested and comes with a Certificate of Analysis, which is worth reading on the product page before you buy. As with any supplement, it isn't a substitute for advice from your own doctor, and we make no claims about what these products do.

What's worth a look

Most of the range is shown with a crossed-out list price next to a lower everyday price; here are six from across the store.

The NMN capsules are the cheapest way into the range at $29.90 for the smallest option, while the Silver Reverse Complete System pairs the hair capsules with the serum for $99.90, less than buying the two separately at $49.90 and $69.90. Fisetin 500mg capsules are another popular line at $45.00 (list price $79.00).

Beyond the shop, Aeternum runs a news section and podcast on longevity research, a points-based rewards program for account holders, and a retail partners program. You can also browse by product type (bundles, hair care, skin care, supplements and test kits) to narrow the range quickly.

How to save more

• Codes usually can't be stacked, so compare: for two different products LONGEVITY50 halves the cheaper one, while the bundle builder's 15-18% off may work out better if you're buying three or more.
• The ready-made kits (the Skin Care Day & Night Bundle, the Silver Reverse system) are already priced below their parts, so check the kit before adding items one by one.
• If you reorder the same formula every month, compare the subscription price with a one-off order plus a code.

Delivery is quoted at 2-5 business days from local stock, shipping is calculated at checkout, and the store says no customs or duty charges apply.
