Key Ingredients

Bovine Collagen Peptides

Sourced from grass-fed cows in the USA, these peptides are rich in Type I and Type III collagen—the most abundant types in your body, essential for youthful skin, strong joints, and healthy hair.

L-Tryptophan

Supplies the "missing" essential amino acid that makes collagen a complete protein. The body also uses tryptophan to produce serotonin and melatonin, which help regulate mood, sleep, and appetite.

AstraGin®

A plant-based powerhouse that increases amino acid absorption by up to 67%, maximizing your body’s ability to repair and rebuild tissue.

Hyaluronic Acid

A moisture-binding matrix that hydrates skin, lubricates joints, and promotes elasticity, working synergistically with collagen peptides for optimal results.

Vitamin C

A crucial cofactor for collagen synthesis, this nutrient optimizes collagen efficacy by helping the body produce stronger, more stable collagen fibers.

portrait of Ann Louise Gittleman

"As we age, collagen production naturally declines, affecting everything from our skin's elasticity to our joint comfort. After witnessing thousands struggle with premature aging and structural health issues, I knew we needed more than just basic collagen—we needed the purest, most amino-complete collagen solution possible.

10 years in the making, I've spent the last year perfecting this formula before bringing it to the market, meticulously selecting each ingredient and testing countless combinations until we achieved something truly extraordinary. What makes me especially proud is how versatile and easy to use it is—with no taste, it mixes effortlessly into soups, stews, sides, and smoothies, making it a seamless addition to any daily routine.

The four unique cofactors we've included work synergistically to guarantee real, visible results: stronger hair, thicker skin, more powerful muscles and bones, and unmatched joint relief. Having used it personally and witnessed its transformative effects in my practice, I can confidently say this formula delivers results you can feel and see. I'm thrilled to finally make this breakthrough formula available to everyone who wants to experience the difference that properly formulated, complete collagen can make."

Collagen

I have been taking it for about a month. I like that it has protein with the collagen, as that helps my overall daily protein intake. I can see results in the strength of my nails. I have two dislikes. One is the tast, but mixing it in my morning smoothie with yoghurt and fruit takes care of it. I do not like it in my tea or coffee because it ruins it. I still need to find another way to take it if I did not get around to my smoothie for one reason or another. The other dislike is the packaging. The canister is too big for my hands--the circumference is too large-, and my hands actually hurt trying to open it. My hands are actually larger than average for a woman.

The Jury is still out

I'd been hearing about Collagen for a long time, but was always reluctant to give it a try knowing it contained animal products. So when Uni-key came out with their own collagen and after reading Ann Louise’s testament of its qualities I decided to try it. Ive now been using it 1x/day for a month and am not entirely sure of the benefit. I take it mainly for cracking nails and dry/limp hair. My nails do seem maybe a bit better and hoping for better hair may have been a pipe dream anyway. So I'll keep using it for another month and will then make up my mind whether to continue or not. What I can say is if I do continue it will definitely be with Uni-key as I trust the quality of their products completely.

Helps my joint pain

I have to say that I have been taking it for less than a month, and yesterday when it was pouring rain, my knees felt just fine! Thank you for this great product. It does, however, have a small taste. So I put it in a cup of hot tea.🥰

I love Collagen 4+!

Finally! A collagen that ticks all the boxes. At 66 I can use all the extra support I can get for my skin, hair and nails. I love Collagen 4+! It mixes easily in water, soup, broth, yogurt - you name it. I always feel an extra burst of gentle energy after taking it. I know and trust Unikey products for their purity, efficacy and 3rd party tested formulas. This product is a win win for me!
