Summary
- Collagen makes up a large share of your body's protein, yet production drops every year with age, which contributes to wrinkles, weaker connective tissue, reduced strength, and slower recovery
- Researchers identified a specific pattern of collagen amino acids — glycine, proline, and hydroxyproline — that may signal your body to repair tissue, support physical function, and influence biological aging
- Human participants who consumed a collagen amino acid formulation showed measurable improvements in skin texture, hydration, and elasticity within one to three months
- After six months, biological age markers shifted younger on average, suggesting that targeted collagen amino acid supplementation may influence internal aging processes rather than appearance alone
- Supporting collagen at the root involves adequate protein with collagen-rich sources, vitamin C intake, protection against collagen breakdown, and high-quality collagen or gelatin sourced from properly raised animals

| 0:00.0 | Your body is made of more collagen than almost any other protein. |
| 0:03.7 | And it has been quietly disappearing since your mid-20s. |
| 0:06.8 | Research published in NPJ aging found that collagen production drops roughly 1 to 1.5% every single year once decline begins. |
| 0:14.1 | That means by the time most people notice sagging skin or aching joints, |
| 0:18.7 | they have already lost a significant portion of the structural protein |
| 0:21.5 | holding their body together. |

| 0:46.7 | Hello and welcome to Dr. Mercola cellular wisdom. Dr. Mercola explains that collagen accounts for 12 to 17 percent of all protein in mammals. It is the primary structural component |
| 0:53.7 | in skin, tendons, ligaments, cartilage, bones, and the lining of the gut. |
| 0:59.0 | When production slows, the effects cascade across multiple systems simultaneously. |
| 1:05.0 | Skin loses elasticity, joints lose their cushioning. |
| 1:09.0 | Bones become more brittle. Even the intestinal barrier |
| 1:12.9 | begins to weaken, opening the door to systemic inflammation. The recent research draws a critical |
| 1:17.7 | distinction that most supplement companies ignore, not all collagen is created equal. Generic collagen |
| 1:23.5 | supplements contain large protein fragments that the body struggles to absorb efficiently. |
| 1:29.3 | Specific low molecular weight collagen peptides, particularly tripeptides like glycine-hydroxyproline, |
| 1:35.7 | are dramatically more bioavailable. These smaller peptides survive digestion intact and reach |
| 1:41.0 | target tissues in measurable concentrations. Studies show these targeted tripeptides can stimulate fiberblasts, |
