The natural process of aging can take a toll on your skin, joints, hair, and even mental wellbeing. As we age, our bodies produce less and less collagen. But now, you can fight back! Collagen 4+ changes the game on how collagen is absorbed systemically to help restore and rebuild natural collagen production, making skin thicker, more resilient, less wrinkled and papery thin. This advanced formula combines premium bovine collagen peptides with four uniquely powerful cofactors to help you look and feel rejuvenated from the inside out.
Packed with essential amino acids, collagen supports stronger hair, glowing skin, and healthier joints, all while boosting your body’s natural vitality. Imagine firmer, more radiant skin, improved gut health, and the energy to move freely. With every dose, you’ll feel the difference from the inside out, fueling your confidence and supporting your overall well-being. Say hello to a stronger, healthier you—one scoop at a time with Collagen 4+!
Reduce wrinkles, improve elasticity, and hydrate your skin for a youthful glow.
Ease stiffness and support an active lifestyle.
Revitalize your natural beauty from the inside out.
Enhance muscle repair and rebuild strength for everyday activities.
Collagen 4+ is uniquely designed to target the effects of aging and wear by enhancing collagen production and absorption. Here’s how it works:
Made with bovine collagen, naturally rich in Type I and Type III collagen—the types that comprise 95% of your body’s natural collagen. Supports skin, hair, nails, joints, muscles, and more. Bovine collagen contains the super 3 aminos: Glycine, Proline, and Hydroxyproline, which make up 50% of collagen and are vital for tissue repair, joint ligament health and muscle strength.
AstraGin®, a plant-based nutraceutical, to increase amino acid absorption by up to 67%. Studies demonstrate when AstraGin is added to protein, it increases protein synthesis for optimum muscle growth and repair.
L-tryptophan to supply the “missing’ essential amino acid that makes our collagen a complete protein. The body uses tryptophan to produce serotonin and melatonin, which help regulate mood, sleep, and appetite.
Hyaluronic Acid to provide a moisture-binding matrix, that when combined with collagen boosting peptides, works synergistically to improve skin hydration and elasticity, joint lubrication, wound healing and even dry eyes.
Vitamin C to provide a powerful precursor to the production of collagen. As a crucial cofactor for collagen synthesis, this nutrient optimizes collagen efficacy by helping the body produce stronger, more stable collagen fibers.
The purest, most amino-complete collagen on the market that changes the game on how collagen is absorbed systemically. What I especially like is that it has no taste, mixes easily and I can throw it in soups, stews, sides and smoothies. I’ve waited ten years to perfect this product, and now I’m thrilled that it’s available to everybody with its four unique cofactors. Each of these unique additions guarantees stronger hair, thicker skin and more powerful muscles and bones with unmatched joint relief. “

UNI KEY Collagen 4+ has a very light pleasant flavor and neutral aroma. It mixes extremely well in water with no clumps. In apple juice it was completely undetectable. It also mixes well in hot water, and I enjoyed sipping it!

I like the fact that there is 10 grams of protein in each serving, which is one level scoop. I love that there are no “filler” ingredients in it!
I have used many UNI KEY products for well over 20 years. I trust them to always sell high quality products. I am so glad that they have come out with a Collagen product as I know how important it is for our joints, bones and skin, especially as we get older!

I’ve been enjoying the new UNI KEY Collagen supplement for 4 days and cannot wait to see long term results! It mixes well in either my morning cup of coffee or bone broth. I think the extra ingredients in it are amazing to make it more absorbable and to encourage what a collagen supplement is supposed to do. So far, so good!
