Dr. Berg explains how daily collagen intake supports skin, joints, sleep, gut health, and more, especially after age 40.
Key Takeaways
- Daily collagen supplementation can significantly improve skin, joint, hair, sleep, and gut health after 40.
- Glycine is a critical amino acid in collagen that supports multiple body functions including detox and blood sugar control.
- Modern diets are deficient in collagen, making supplementation important especially with aging.
- Collagen peptides signal the body to repair connective tissues, not just provide raw material.
- Avoiding collagen-depleting factors like sugar and seed oils helps maintain collagen levels.
Summary
- Collagen makes up 30% of the body's protein but is underconsumed in modern diets, especially from tender meats.
- Aging leads to collagen loss, affecting skin elasticity, joint health, hair, sleep quality, and gut integrity.
- Glycine, a key amino acid in collagen, supports deep sleep, gut repair, detoxification, blood sugar regulation, and anti-inflammatory effects.
- Collagen peptides act as signaling molecules to stimulate fibroblasts for tissue repair.
- Dietary collagen is best supplemented via powders or bone broth, ideally with vitamin C to enhance absorption.
- Collagen destruction is accelerated by sugar, seed oils, stress, and aging.
- Recommended glycine intake is 4-10 grams daily, achievable with one scoop of collagen powder.
- Glycine also supports liver detoxification through glutathione production and may slow premature hair graying.
- Collagen benefits extend to reducing gout risk, kidney stones, and supporting blood protein (heme) and gum health.
- Modern diets lack nose-to-tail consumption, reducing natural collagen intake compared to ancestors.
