Collagen Explained: Your Body’s Invisible Support System
Collagen is the structural protein that supports your joints, strengthens your bones, and holds your connective tissues together. It also plays a key role in maintaining healthy skin, hair, and nails. From movement to appearance, collagen helps keep your body functioning and feeling its best.
Why Collagen Is Essential—Head to Toe
Collagen isn't just about beauty—it's about structure, strength, and movement. This protein forms the foundation of your body's connective tissue network. It cushions joints, strengthens bones, supports muscles, and reinforces everything from ligaments to blood vessels.
And yes—it also helps maintain smooth skin, healthy hair, and strong nails. When collagen is abundant, you feel the difference from the inside out.
How Collagen Declines as You Age
Your body produces less collagen every year after your mid-20s. By age 40, collagen levels may drop by 1% or more annually—leading to visible and physical changes that only accelerate with time.
Increase your collagen, protein, and amino acid intake—especially for supporting joint comfort, mobility, and muscle recovery. It also helps support healthy skin, stronger nails, and resilient hair. With high-quality powders, you always know exactly how much collagen you're getting in every scoop.
