What it does: Collagen supports the structure, strength, and flexibility of skin, joints, and bones. It is involved in tissue repair, skin elasticity, and maintaining the integrity of cartilage and bones.
How it is used: Collagen is commonly used in supplements for joint health, skin appearance, hair and nail strength, and overall structural support as people age or experience increased physical stress.
Natural sources and supplement forms: Collagen naturally occurs in animal connective tissues (such as chicken, beef, and fish skin or bones). Supplement forms include hydrolyzed collagen peptides, gelatin, and occasionally undenatured collagen, usually available as powders, capsules, or drinks.
Why it appears in supplement formulas: Supplement brands use collagen to support skin hydration and elasticity, promote healthy joints, and help counter the body’s natural collagen decline with age—features valued by those seeking to maintain active lifestyles or youthful skin.
What to know before use: Most collagen supplements are derived from animal sources and are not suitable for vegetarians or vegans. Individuals with specific allergies (such as fish or egg) should check collagen source information to avoid adverse reactions.
Interesting Fact
Collagen: Your Body’s Most Abundant Protein
Collagen is the most plentiful protein in the human body, making up about one-third of total protein content. It forms a crucial part of connective tissues, such as skin, tendons, and bones. While your body naturally produces collagen, this supply gradually decreases with age, which is why collagen is commonly added to supplement formulas.
