Kollagen dietary supplements: doctors’ reviews
Chapter 1: Collagen is the basis of health and beauty: what do experts say?
Collagen is a fibrillar protein, which is the main structural component of the connective tissue of the body. It provides the strength and elasticity of the skin, cartilage, bones, tendons and ligaments. With age, the production of collagen naturally decreases, leading to wrinkles, joint pain, weakening of bones and other signs of aging. In this regard, the additions of collagen (dietary supplements) have become popular, offering solutions to maintain health and beauty. Consider what doctors say about the additives of collagen, their effectiveness, safety and possible side effects.
1.1. The role of collagen in the body: medical prospect
Revumatologists, dermatologists, traumatologists and sports doctors emphasize the critical role of collagen in maintaining the health of various body systems:
- Leather: Collagen is about 70% of the skin protein. It provides its elasticity, elasticity and moisture. A decrease in the level of collagen leads to the formation of wrinkles, loss of tone and dryness. Dermatologists note that maintaining a sufficient level of collagen can slow down the aging process.
- Joints: Collagen is the main component of cartilaginous tissue, which amortizes the joints and ensures their mobility. Rheumatologists and traumatologists confirm that a decrease in the level of collagen leads to degenerative changes in cartilage, the development of osteoarthritis and joint pain.
- Bones: Collagen forms the basis of bone tissue, ensuring its strength and flexibility. Reducing the level of collagen increases the risk of osteoporosis and fractures.
- Muscles: Collagen plays a role in maintaining the integrity and function of muscle tissue. Sports doctors note that collagen additives can help restore muscles after training and reduce the risk of injuries.
- Digestive system: Collagen is an important component of the intestinal mucosa. Some gastroenterologists suggest that collagen supplements can help strengthen the mucous membrane and improve digestion.
1.2. Types of collagen: What is important to know when choosing dietary supplements?
There are many types of collagen, each of which plays a certain role in the body. The most common types of collagen used in dietary supplements:
- Type and: The most common type of collagen contained in the skin, bones, tendons and ligaments. Supports skin elasticity, bone strength and connective tissue health.
- Type II: The main component of cartilage fabric. Supports joint health and reduces inflammation.
- Type III: Contained in the skin, muscles and blood vessels. Provides tissue elasticity and supports the health of the cardiovascular system.
- Type IV: Contained in basal membranes that support the structure of organs and tissues.
- Type V: Contained in the hair, placenta and cell surfaces.
Doctors recommend choosing dietary supplements containing type I and III collagen to maintain skin health, and type II collagen for joint health.
1.3. Forms of collagen in dietary supplements: hydrolyzed collagen, peptides and gelatin
Collagen dietary supplements are available in various forms, including:
- Hydrolyzed collagen (collagen peptides): Collagen, split into small peptides, which are easier to absorb by the body. Doctors consider a hydrolyzed collagen the most effective form of collagen for oral administration.
- Gelatin: Partially hydrolyzed collagen. Less effective than a hydrolyzed collagen, but can also have a positive effect on the health of the joints and skin.
- Non-unauthorized collagen type II (UC-II): It retains its three -dimensional structure, which allows it to interact with the immune system and reduce inflammation in the joints.
Doctors often recommend hydrolyzed collagen due to its better digestibility and bioavailability.
Chapter 2: The opinions of doctors on the effectiveness of collagen dietary supplements: the results of clinical research
The effectiveness of collagen dietary supplements is the subject of numerous clinical studies. Doctors rely on the results of these studies in order to evaluate the benefits and risks of the use of collagen additives.

Many dermatologists recommend collagen supplements to improve skin condition. Clinical studies confirm that the intake of collagen can:
- Reduce the depth of wrinkles: Studies show that the intake of hydrolyzed collagen for several weeks or months can significantly reduce the depth of wrinkles and improve skin elasticity.
- Improve skin moisture: Collagen helps to keep moisture in the skin, making it more moisturized and smooth.
- Increase collagen density in the skin: Reception of collagen stimulates the production of its own collagen in the skin, increasing its density and elasticity.
In one study published in the journal Journal of Cosmetic Dermatology, it was shown that taking 2.5 grams of collagen peptides per day for 8 weeks significantly reduced the depth of wrinkles around the eyes and improved skin elasticity in women aged 45 to 65 years.
2.2. Collagen for joint health: rheumatological and traumatological studies
Rheumatologists and traumatologists often recommend collagen additives to relieve joint pain and improve their mobility. Clinical studies confirm that the intake of collagen can:
- Reduce joint pain: Studies show that the intake of type II collagen can reduce joint pain in patients with osteoarthritis.
- Improve joint mobility: Collagen helps restore cartilage and improve joint mobility.
- Reduce inflammation in the joints: Collagen has anti -inflammatory properties and can reduce inflammation in the joints.
In one of the research published in the journal Osteoarthritis and Cartilage, it was shown that taking 40 mg of non-aatured collagen type II (UC-II) per day for 6 months significantly reduced the pain in the joints and improved their mobility in patients with knee-controlal joint.
2.3. Bones collagen: research in the field of osteoporosis
Some studies show that collagen supplements can have a positive effect on bone health, especially in postmenopause women who are at risk of osteoporosis. Reception of collagen can:
- Increase bone density: Collagen helps to increase the density of bone tissue and reduce the risk of fractures.
