Reviewers Swear By This Supplement For Stronger Nails & Hair Health (& It's 30% Off)*

Collagen boasts a slew of benefits, and the science backs it up. It supports skin's elasticity1, nurtures bone health2, and contributes to muscle growth3, to name a few.* But not all collagen powders are created equal, and the quality of a given formula can determine what benefits it delivers and to what extent.

If a clean ingredient list is a nonnegotiable for you, you'll love what's inside mindbodygreen's beauty & gut collagen+. Sourced from grass-fed, pasture-raised Brazilian cows, the formula combines 17.7 grams of premium collagen peptides (types I & III) with hyaluronic acid, biotin, L-glutamine, turmeric, SGS from broccoli, and vitamins C and E.

Available in both chocolate and an unflavored variety, this collagen powder can be combined with your morning cup of joe (bonus points if it's brewed with clean coffee+) or added to your favorite smoothie, soup, or other favorite recipe for an easy nutrient boost. What's more, the powder is currently up to 30% off (when you spend $200 or more) with promo code BESTSALE30 at checkout, as part of mbg's Black Friday sale. The sitewide discount is our biggest savings of the year and extends to our entire lineup of bestsellers and personal care items. And until Sunday, you'll also get a free bottle of vitamin C potency+ for extra antioxidant support.*

Naturally, we recommend bundling up to take full advantage of the deal. But you'll still save 20% on orders $49+ and 25% off orders $98+. (Again, just use codes BESTSALE20 or BESTSALE25.)

If a steep discount isn't enough to convince you to give this collagen powder a go, the reviews should be. This blend earned glowing praise from experts—including functional medicine practitioners, fitness trainers, and nutrition experts—and now, real customers are seeing the results for themselves.

"I haven't missed a day taking my collagen since trying MBG. It tastes amazing and I could really feel a difference in my gut health, and I love how my skin looks and feels."* —Jennifer S.

"I love how easy this is to use. I personally put it in my morning coffee and blend it with other good stuff for a bulletproof coffee. I have noticed a big difference in my skin since I have been using this. Less dryness and fine lines seem fuller. Also, my joints are not as stiff. Very happy with MBG products!"* —Fran P.

"Within a month of using it, I got compliments that I was glowing and specifically my skin is glowing! Going on month 2. Can't wait to see more positive changes!"* —Giovanna H.

"I've struggled with weak, short nails for YEARS. This has made my nails grow so long and thick. I am so happy."* —Sara K.

What the science says: Research shows collagen may help with improved growth rates and breakage of nails. One study found that taking collagen daily for 24 weeks helped support participants' nail health7.*

"Love this product. I use it in my coffee everyday. I have lost track of the day I started. I am on my second or third package. (Guess it has not helped my memory yet?) I noticed within weeks, my nails are stronger and best of all I have more hair! I feel good using this product."* —Peggy M.

What the science says: Amino acids are essential for the body to build keratin, which is the primary material in hair. Collagen peptides8 have many of these essential amino acids, including proline.*
