The Feed

What's in the box: You choose your own order from energy gels, chews, electrolyte powders, protein, supplements and gear, including mixed gel packs you build across brands.

The Feed is an online sports nutrition store rather than a classic curated subscription box. It stocks fuel, hydration, protein, supplements, superfoods and training gear from brands such as Maurten, Skratch Labs, UCAN, Science in Sport, Momentous and LMNT. It also sells its own Feed Lab creatine. For cyclists, the most useful feature is the build-your-own gel pack, which lets you mix gels across brands instead of committing to a full box of one product. That makes it a practical way to test what your stomach tolerates before a long ride or race. The site also publishes Top 10 lists for hydration, energy gels, recovery shakes and other categories, which help narrow down a crowded market. Shipping is listed as free on all orders. The catalog leans heavily into wellness and recovery products such as sleep shots, magnesium, stress supplements and longevity items, so riders who only want on-bike fuel will have to look past a lot of extras. The site does not clearly explain whether recurring deliveries are available or how they work, so check the account and checkout options if you want an automatic refill. Overall, it is a strong one-stop shop for endurance nutrition, but it works more like a specialist retailer than a surprise box.
