🧬 What Are Collagen Peptides?
Collagen, the structural protein found in skin, bones, cartilage, and connective tissue, is broken down into smaller units called peptides for easier digestion and uptake. The most commonly supplemented forms are Types I, II, and III:
-
Type I & III: Ideal for skin, hair, nails, and connective tissue health
-
Type II: Targeted toward joint cartilage and osteoarthritis relief
🌟 Potential Benefits
Skin, Hair & Nails
-
Enhances skin hydration, elasticity, firmness, and may reduce wrinkle appearance after ~4–8 weeks of daily use
-
Best results often seen with marine collagen for skin benefits
Joints & Bones
-
May reduce joint pain, including for osteoarthritis, and support cartilage repair
-
Evidence suggests improvement in bone mineral density in postmenopausal individuals
Muscle Mass & Recovery
-
When paired with resistance training, collagen peptides may help increase fat‑free mass and strength, especially in older adults
Gut, Heart & Anti-inflammatory Effects
-
Emerging research (e.g. from fish-cod collagen) suggests potential anti-inflammatory and gut-lining support, even for ulcerative colitis
“Significantly reduced colonic tissue damage… restored microbial balance.”
-
In animal models, collagen peptides may help lower blood pressure, improve vascular function, and regulate blood sugar
🧰 Choosing a Collagen Peptide Supplement
Key features to look for:
-
Clearly labeled collagen type (I, II or combo) to match your goal
-
Low molecular weight peptides (<2,000 Da, e.g. tripeptides) for optimal absorption
-
Reputable third‑party certifications (e.g., NSF, USP, ConsumerLab, Halal, GMP)
