What Is Collagen?
Collagen is the most abundant protein in the body, making up about 30% of the total protein content. It is the essential “glue” that helps to hold connective tissues together. Collagen can be found in muscles, bones, skin, ligaments, and tendons. The body naturally produces collagen by breaking down dietary proteins into amino acids, which are then used to build collagen. This process requires certain nutrients, including vitamin C, zinc, and copper. However, collagen production starts to decline as you age, leading to signs of aging such as wrinkles, sagging skin, and weaker joints. Collagen in full length cannot be absorbed in the digestive tract because of its length and spatial conformation.
Exploring Collagen Peptides & Supplements
Collagen peptides, also known as hydrolyzed collagen, are shorter chains of collagen that have been broken down for easier absorption by the body. When we refer to collagen supplements, we are specifically talking about collagen peptides supplements.
In recent years, various forms of collagen supplements have gained popularity, such as hydrolyzed collagen pills, collagen powder, and collagen drinks. Collagen supplements are made of the bones of animals, the skins of cow and fish scales. Most of them are hydrolyzed and could be absorbed by our bodies easily.
Advertising taglines often claim that consuming collagen can enhance skin health, improve elasticity, and alleviate joint pain. But do collagen supplements really work? 🤔
Benefits of Collagen Supplements
1. Improve Skin Health
Collagen can strengthen our skin to prevent the formation of wrinkles. It can also enhance the skin elasticity and hydration to soothe dry and broken skin. According to the research results, daily intake 2.5–5 grams collagen supplement for 8 weeks (about 2 months) can help the skin cells keep renewing and repairing. Skin elasticity and skin moisture can be improved significantly.
2. Improve Joint Health
Collagen helps to protect the integrity of cartilage to enhance the flexibility of joints and reduce joint pain. Based on some studies, you are suggested to consume 8–12 grams of collagen supplement daily to relieve joint pain and slow down age-related joint deterioration.
3. Improve Bone Health and Prevent Bone Loss
Bones are mainly made of collagen. That’s why collagen is good for the formation of new bone. It can also strengthen the bones. With reference to the study result, women who took 5 grams of collagen daily for 12 months increased around 7% in the bone mineral density.
4. Improve Appearance of Hair & Nails
Hair and nails are composed of a protein called keratin, supported by collagen fibers in the hair follicles. Collagen helps to provide structure and support to the hair follicles, promoting healthy hair growth and preventing breakage. A sufficient intake of collagen reduces nails brittleness and improves their overall appearance.
