Skin secrets

Jennifer Aniston, Sofia Vergara and Kourtney Kardashian add this secret ingredient to their smoothies for a beauty boost

Celebrities are powering up their smoothies with collagen for radiant skin and healthy nails

Ever since she stepped into Rachel's shoes, Jennifer Aniston has been a beauty icon across the globe. It's been 15 years since the series ended, and the 51-year-old actress is just as radiant as her days spent in Central Perk. But how does she do it? Well, it’s a secret that also has fans in fellow stars Sofia Vergara and Kourtney Kardashian: collagen.

No, we’re not talking about facial fillers! Instead, these stars prefer adding collagen to their drinks and smoothies. Jennifer is reportedly a fan of Vital Proteins Pasture-Raised, Grass-Fed Collagen Peptides ($25), a supplement powder.

The Friends star has a basic smoothie recipe – some sort of pure protein, plus bananas, blueberries, frozen cherries, stevia, a mix of greens, maca powder, and a little cacao. “I've been seeing a difference! 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,” the actress told Byrdie.

Collagen is a protein that gives the skin resilience and elasticity to help fight the appearance of wrinkles. It's also ideal for maintaining healthy hair, joints, cartilage, tendons and bones.

But she's not the only one who swears by collagen. Sofía Vergara divulged to Health Magazine that–unlike Jennifer, who has it in the morning, she adds a spoonful of powdered collagen to her chamomile tea every night.

Kourtney Kardashian also can't resist the huge benefits of collagen. In one of her articles for Poosh–the website where she shares her beauty secrets– she explains the changes she's seen in her body since consuming collagen (she even created her own formula for Vital Proteins).

“I've been drinking collagen... every morning for years, and it's made such a difference in my body: I notice a glow in my skin, my hair is healthy, and my nails are so much stronger. It also helps my body recover more quickly from my intense workouts by supporting my bones and joints,” she explained. “Collagen has unique properties that can't be found in other protein sources, which is why I add it into my routine.”
