Collagen - Benefits, Types and Market Analysis
In recent years, collagen has become an integral ingredient of skincare nutritional supplements and products. In 2020, U.S. consumers were estimated to spend $293 million on collagen products.[i] This blog explains everything you need to know about collagen including, its health benefits, functions, market analysis, and much more.
What Is Collagen?
Collagen is present in fibrous tissues, including skin, ligaments, and tendons. It’s abundantly present in blood vessels, bones, cornea, digestive tract, and cartilage. Collagen is the primary component of the endomysium (a thin layer of connective tissue) in muscle tissue.
What Does Collagen Do in Our Body?
Collagen provides strength to several body parts. It holds cells and tissues together in blood vessels, digestive tract, as well as all glands and organs. It protects the skin by helping prevent the absorption and spread of micro-organisms, environmental toxins, pathogenic substances, and cancerous cells.[v] Collagen is also a fundamental component of nails and hair and contributes to their maintenance.
What Is the Function of Collagen?
Collagen is an insoluble, and fibrous protein. Collagen’s primary function is to support structures and anchor cells to each other.[vi]
The function of collagen in the skin is to offer essential strength and elasticity. In the dermis (middle layer of the skin), collagen enables new cell formation and replaces dead skin cells.
Collagen protein function includes helping provide protective coverings for delicate body organs, such as the kidneys.
What Are the Different Types of Collagen?
Our body contains at least 16 types of collagens, with the following five being the primary ones:[vii]
- Collagen Type 1 – Contributing to around 90% of the total body collagen, these densely packed fibers are primarily responsible for providing structure to skin, tendons, bones, connective tissues, teeth, and fibrous cartilage.
- Collagen Type 2 – Mostly found in joint cushions and elastic cartilage, type II collagens are made of loosely packed fibers.
- Collagen Type 3 – The primary function of type 3 collagen is to support the structure of arteries, organs, and muscles.
- Collagen Type 4 – Type 4 collagen present in the skin layers helps with filtration.
- Collagen Type 5 – Type 5 collagen is critical for fibrillation of type 1 and 3 collagens.[viii]
Health Benefits of Collagen
Collagen is vital for many human body functions, and oral collagen supplements offer a wide range of health benefits.
Collagen Benefits for Skin
Several studies show that supplements containing collagen benefit skin by promoting elasticity, hydration and reducing dryness and wrinkles. Daily consumption of collagen supplements helps reduce visible signs of aging too.[ix] [x]
Collagen Benefits for Joints
Collagen supplementation can help promote joint comfort and flexibility. A study also revealed that collagen supplementation helped improve knee joint discomfort in athletes.
Collagen Benefits for Nails
Collagen intake helps strengthen nails. According to a study, oral supplementation of collagen promoted the growth of nails and reduced their brittleness.
Increased Muscle Mass
Collagen Benefits for Bones
Bones contain collagen as well as other proteins and minerals. Aging impacts collagen levels and bone mass in the human body. Collagen supplement studies show that supplementation helps promote healthy bone density.
A study also revealed that calcium and collagen supplement combination helped postmenopausal women maintain bone health. Another study shows that collagen supplements can help enhance bone mineral density and bone markers in women experiencing menopause.
Collagen Benefits for Heart
According to a study, collagen can significantly promote artery flexibility in healthy adults and support healthy HDL levels already within a healthy range.
Nutrients for Collagen Production
The human body combines proline and glycine using vitamin C to make procollagen which is further modified into collagen. Following are some of the nutrients that stimulate collagen production.[xii] [xiii]
- Glycine – Found in chicken skin, pork skin, gelatin, protein-containing foods.
- Proline – Found in dairy products, egg whites, wheat germ, mushrooms, asparagus, cabbage.
- Vitamin C – Found in citrus fruits, strawberries, bell peppers.
- Copper – Found in organ meats, lentils, cashews, cocoa powder, sesame seeds.
- Silicon – Found in oranges, beets, cherries, apples, figs, eggplants, almonds, grapes, tomatoes, strawberries.
- Lysine – Found in beans, tofu, cooked spinach, beets, peas, quinoa, sweet potatoes, pumpkin, and squash seeds.
- Zinc – Found in shellfish, meat, bread, cereals, dairy.
- Manganese – Found in nuts, tea, bread, cereals, green vegetables.
Collagen Market Analysis
The rise in preventive healthcare and the growing desire to prevent premature signs of aging among consumers primarily drive collagen market growth.
The market is segmented into collagen powder market, capsule and gummies, drinks, and shots, as well as other formats. Marine sourced collagen peptide derived from unused fish parts is becoming prevalent among manufacturers and is encouraging environmental sustainability. The Asia Pacific seems to be the most rapidly growing collagen supplement market.
