Chipped, peeling, or brittle nails? We’ve all been there. While polish can cover up the damage, true nail strength starts from within. That’s where collagen shines. Beyond its glow-boosting benefits for skin and hair, collagen plays a major role in keeping your nails healthy and strong. But how, and why? Here’s what science says…
What Does Collagen Do for Nails?
Your nails are made primarily of keratin, a structural protein that relies on amino acids to grow and repair itself. Collagen is rich in those same amino acids (especially proline, glycine, and hydroxyproline), which serve as building blocks your body uses to form keratin. By supplying your body with these essential nutrients, collagen helps support nail thickness, hydration, and smoothness—all signs of stronger, healthier nails.
Scientifically, How Does Collagen Work for Nails?
As we age, our natural collagen production declines, meaning fewer amino acids are available to support nail growth. When you consume collagen, it’s broken down into peptides and amino acids that circulate through your bloodstream. These nutrients stimulate your body’s own production of keratin and can even enhance blood flow to the nail bed. Resulting in nails that grow faster, break less, and recover quicker from daily wear and tear.
What Studies Have Been Done to Verify Collagen’s Efficacy for Nail Health?
Collagen’s benefits for nail strength aren’t just anecdotal, they’re backed by science: in an open-label trial published in the Journal of Cosmetic Dermatology in 2017 (PubMed: 28786550), participants who took 2.5g of specific bioactive collagen peptides daily for 24 weeks experienced a 42% decrease in the frequency of broken nails and a 12% increase in nail growth rate. Overall, 80% of the participants also agreed that the supplementation improved their nails' appearance. Earlier research also shows collagen supplementation helps decrease nail brittleness and promote faster growth rates.
Takeaway: Consistency works, and collagen really can make a visible difference.
How Long Do I Have to Take Collagen to See Stronger Nails?
Most studies show noticeable results after 4–8 weeks of consistent collagen use, with continued improvements over time. Like any beauty routine, it’s all about consistency. So daily use is the key to maintaining stronger, smoother nails.
What is the Best Way to Take Collagen for Healthier Nails?
Collagen powders and capsules are fairly common, but they’re not always the most convenient (or enjoyable) option. When it comes to simplicity, collagen drinks will be the best way to get your daily dose. Yet, not all are made equal.
Unlike typical gritty and unpleasant collagen drinks, Pretty Tasty teas are refreshing, smooth, delicious and packed with premium bovine-sourced collagen in every sip. No mixing. Zero sugar. No mess. It’s the easiest (and prettiest) way to make collagen part of your daily ritual. We use hydrolysate collagen for better bioavailability and faster absorption—delivering visible results from within.
