Not All Collagen Is Created Equal: Here’s Why

Our new Collagen 4+ isn’t just another collagen powder—it’s a groundbreaking formula designed to deliver maximum results. With carefully selected cofactors like L-tryptophan and AstraGin®, UNI KEY Collagen 4+ outshines industry heavyweights like Vital Proteins, Ancient Nutrition, and Thorne. Let’s break down what makes Collagen 4+ the superior choice.

The UNI KEY Advantage

Collagen 4+ contains bovine collagen peptides plus four key cofactors that changes the game on how collagen is absorbed for maximum benefit: AstraGin®, L-Tryptophan, Hyaluronic Acid and Vitamin C.

Key Ingredients

Bovine Collagen Peptides:
Made with grass-fed 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.

Four Cofactors:

1. A Complete Protein with L-Tryptophan
Unlike most collagen supplements on the market, UNI KEY Collagen 4+ is a complete protein thanks to the addition of L-tryptophan—the “missing” essential amino acid. Tryptophan supports the production of serotonin and melatonin, which regulate mood, sleep, and appetite. While other brands like Vital Proteins, Ancient Nutrition, and Thorne provide high-quality collagen, they don’t address the gap of an incomplete amino acid profile. Collagen 4+ bridges this gap, giving your body what it truly needs for optimal wellness.

2. Superior Absorption with AstraGin®
UNI KEY Collagen 4+ incorporates AstraGin®, a plant-based nutraceutical proven to increase amino acid absorption by up to 67%. This innovative addition ensures that every scoop of Collagen 4+ works harder for your body, maximizing protein synthesis for muscle growth and repair. While Vital Proteins and Ancient Nutrition boast high-quality peptides, they lack this innovative delivery system. Thorne, known for its rigorous standards, also does not include a comparable ingredient for enhanced bioavailability.

3. Hyaluronic Acid for Skin and Joint Health
Collagen 4+ features Hyaluronic Acid, a moisture-binding matrix that enhances skin hydration, elasticity, and joint lubrication. This ingredient works synergistically with collagen peptides to deliver visible improvements in skin health and comfort for joints. Though many competitors focus solely on collagen peptides, UNI KEY takes a holistic approach by combining Hyaluronic Acid for comprehensive results.

4. Vitamin C for Collagen Synthesis
Collagen production depends on adequate levels of Vitamin C, a critical cofactor for collagen synthesis. UNI KEY Collagen 4+ includes Vitamin C to optimize your body’s ability to produce strong, stable collagen fibers. While some competitors like Thorne and Ancient Nutrition include Vitamin C, UNI KEY combines it with its other cofactors for a more synergistic effect.
