Aeternum: longevity supplements and skincare, priced in dollars

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

Aeternum, which also trades as The Aeternum Company, is an online brand built around the longevity supplement trend. The name is Latin for "forever", and the range covers ingredients you'll see discussed in longevity circles, such as NMN, fisetin, GlyNAC and urolithin A, alongside a small skincare line and products aimed at grey hair. It suits people who already know which of these ingredients they want and are happy to buy from a brand that prices in US dollars.

The company's returns address is in Florida, but it says it keeps stock in the UK as well as the US, Europe, Canada, Australia and Asia, so orders don't have to cross the Atlantic. Its shipping policy says orders go out within 24 hours, should arrive in two to five business days and don't carry customs or duty charges. Shipping is worked out at checkout. Bear in mind that your bank may add a fee for paying in dollars.

The site publishes regular articles on longevity research and says each batch comes with a certificate of analysis from third-party testing. As with any supplement, it's worth checking with your GP or pharmacist before adding something new, especially if you take other medication.
