These deals are worth sharing with your “Friends.”

Jennifer Aniston is a longtime fan of collagen peptides brand Vital Proteins, having raved about the company long before becoming its chief creative officer (and collaborating on products) in 2020.

And right now, during Amazon Prime Big Deal Days, select Vital Proteins products are over 30% off — along with a bevy of other celebrity fitness and beauty favorites.

“Collagen is the glue that holds everything together. I’ve always been an advocate for nourishing your wellness from within, which is why I started using Vital Proteins so many years ago,” Aniston said in a press release in 2020.

Among her go-tos? The bestselling Vital Proteins Collagen Peptides Powder Advanced, which has racked up over 193,000 largely glowing customer reviews.

It’s also scored a spot in Aniston’s daily routine, as she once told the brand she adds the “easy to use” formula, featuring 20g of collagen peptides per serving, to her smoothie or coffee.

For something on the more flavorful side, the on-sale options also include lemon ($20, originally $28) and chocolate versions ($19, originally $27), the latter of which the star praised for adding “a flavor boost to [her] smoothie.”

“There’s a collagen peptide that I’ve been loving — I’ve been seeing a difference,” she raved of the product in a 2018 interview with Well + Good. “My nails are stronger and there’s a healthier … how do you explain it? A glow. It’s sort of that working from the inside-out thing.”

She’s not the only star who’s a fan, as Kourtney Kardashian teamed up with Vital Proteins on a line of Poosh-branded products in 2019.

“I’ve been drinking collagen (the main protein found in the body: think hair, skin, bones, muscles, joints, and tendons) every morning for years, and it’s made such a difference in my body,” she told the brand at the time.

Vital Proteins is hardly the only celeb-approved brand on sale right now; be sure to shop the best beauty and tech deals on offer, too, before Amazon’s two-day bargain blowout ends on Oct. 11, 2023.
