Collagen is the most abundant protein in your body—essential for firm skin, strong joints, healthy hair, and gut integrity. Levels drop with age, but certain foods (and bioactive peptides like GHK-Cu mimics) can stimulate natural production and provide building blocks.

Skip expensive powders—focus on whole-food sources rich in glycine, proline, vitamin C, and zinc for optimal collagen synthesis.

Top Collagen & Peptide-Supporting Foods

Bone Broth (Homemade) Glycine and proline in concentrated form—gold standard.
Chicken Skin & Cartilage Rich type II collagen for joints.
Fish Skin & Scales (Salmon, Sardines) Marine collagen peptides, highly bioavailable.
Egg Whites & Shell Membranes Proline and hyaluronic acid precursors.
Citrus Fruits (Oranges, Lemons) Vitamin C essential for collagen formation.
Berries & Kiwi More vitamin C + antioxidants to protect collagen.
Pumpkin Seeds & Oysters Highest zinc sources for synthesis.
Leafy Greens (Spinach, Kale) Vitamin C and magnesium.
Red Peppers Highest plant vitamin C.
Beef & Organ Meats Glycine-rich connective tissue.
