Collagen is a protein naturally produced in our body, with a critical role in maintaining our skin, joints, bones and connective tissue. It contains all 11 of the non-essential amino acids which our bodies can synthesize, and 8 of the 9 ‘essential’ amino acids, which we need have in our diet.
From the Greek word “kólla,” meaning glue, Collagen's strong fibres work like glue to hold things together in our body, muscles, bones, tendons, ligaments, organs, and skin.
Natural production of Collagen in the body declines with age, starting from early adulthood, contributing to the various signs of aging, particularly in skin health and overall bodily function.
Inadequate intake of essential amino acids will impair collagen production, which can lead to weaker skin, bones and connective tissue and can also impact things such as wound healing and immune function.
Supplementing with collagen offers several benefits like:
· Skin elasticity, hydration and firmness, potentially reducing wrinkles and dryness as we age. Studies have shown improvements in skin hydration, elasticity and density after 12 weeks of consistent use.
· Joint health, helping to maintain cartilage and may also relieve pain associated with conditions like osteoarthritis, whilst also improving mobility.
· Bone density and strength, and may help to prevent age related bone loss.
· Muscle mass, as an important component of skeletal muscle, collagen may help to increase or maintain muscle when combined with exercise.
· Heart health, providing structure to arteries. Supplementation has been associated with reduced artery stiffness and improved cholesterol levels.
· Hair and nail strength, and may promote thicker hair and stronger nails by supporting the production of keratin and other proteins essential for growth.
Collagen supplements have unique characteristics, differing from protein supplements in their amino acid profile and a higher content of specific aminos.
Many options are available in collagen supplements, derived from beef, marine or vegan sources, some with added minerals or vitamins for more specific uses. The amino acids are often hydrolysed, meaning they are broken into smaller chains to make them easy to dissolve and absorb.
Since collagen production begins to decline around the age of 25-30, beginning supplementation in your late 20s to early 30s can help maintain optimal collagen levels and potentially slow the visible and functional signs of aging.
