Collagen is an essential protein for our body, having fundamental roles in maintaining skin, bones and joints. It also contributes to their mobility and general tissue integrity.
However, as we get older, collagen production decreases significantly, which can lead to a number of visible and functional changes in the body, such as wrinkles, weakening bones and joints and a slower recovery. Collagen supplements have become more and more popular lately, but there are numerous myths. Dr. Sorina Chelaru, a specialist in diabetes, nutrition and metabolic diseases, clarifies the most common misconceptions about collagen supplements and their real health benefits.
Myth 1: Collagen is absorbed directly into the skin
One of the most common myths related to collagen supplements is that they are directly absorbed into the skin, giving it an almost instant young look. Many people expect the effects of collagen to be visible immediately after administration, but this is not real at all. In reality, ingested collagen does not reach the skin directly, as many believe. According to Dr. Sorina Chelaru: “He does not reach the skin directly, but is digested and decomposed into amino acids that are then distributed throughout the body.” These amino acids are absorbed by the body and transported where necessary, and the effects on the skin become visible gradually. Thus, it is important to have realistic expectations, and the results can vary from person to person.
It should also be mentioned that the process of absorption of collagen does not assume that it will reach exclusively or directly into the skin, but will be generally distributed to the body. The effects on skin elasticity and wrinkles reduce over time, and collagen administration can stimulate the production of natural collagen in the body.
Myth 2: Collagen instantly heals wounds
Another widespread myth is that collagen supplements can instantly cure wounds. Although it is true that it plays an essential role in the healing process, collagen does not offer immediate results; Helps regenerate tissues, but this process takes time. Dr. Sorina Chelaru explains: “I can help in the healing process, but the results can be visible after a few weeks or months of use.” Therefore, we do not have to expect a rapid healing of wounds, but collagen supplements can support tissue regeneration over time, stimulating natural collagen production and improving the structure of the skin.
As for wound recovery, it is essential to understand that collagen supplements cannot replace adequate medical treatment. Collagen can support the healing process, but it is not a “miraculous cure” that will solve any health problem.
Myth 3: Collagen supplements are sufficient for joint health
Many people believe that collagen supplements are sufficient to prevent and treat joint problems. This is a misconception, because collagen supplements should not be considered a unique treatment for joint health. “They do not represent a unique treatment, but can contribute to the health of the joints by reducing inflammation and pain”, warn Dr. Chelaru. Collagen can reduce inflammation and help protect cartilage, but cannot replace other essential measures, such as regular physical exercises, balanced diet and avoiding factors that can degrade joints, such as smoking and obesity.
It is important to understand that joint health depends on a holistic approach, which includes not only collagen supplements, but other interventions for protecting and maintaining cartilage and joints.

Myth 4: Collagen is useful only for skin and joints
Another common myth is that collagen supplements are only useful for skin and joints. In fact, collagen has multiple benefits for other body parts, such as hair and nails. “Collagen is not only useful for the skin and joints, but can also support the health of hair and nails.” emphasizes Dr. Chelaru. Studies show that collagen administration can help reduce hair loss, hair strengthening and accelerating nail growth, thus improving the overall appearance of the body. Collagen plays an essential role in the structure of tissues that compose hair and nails, and supplements can support their regeneration and health.
Myth 5: Collagen is effective only if administered on an empty stomach
Another common myth is that collagen supplements should be administered on an empty stomach to be effective. This is another unfounded mit, because there is no clear evidence to support this. “There is no clear evidence, it can be absorbed by the body effectively regardless of the time of day”, explains Dr. Chelaru. The body can absorb collagen regardless of the moment when it is administered, and its effects depend more on the dose and the regularity of its administration.
Also, collagen can be combined with other supplements or foods, and its efficiency is not significantly influenced by the fact that it is administered on an empty or full stomach. It is important to take into account the recommended dose and be consistent in administering supplements to achieve the best results.
Collagen supplements can have important benefits for the skin, joints, hair and nails, but it is not a magical solution. Dr. Sorina Chelaru recommends: “In order to maximize the benefits of collagen, it is essential to have a balanced diet, rich in vitamins and minerals, to make regular movement and to avoid factors that favor collagen degradation, such as smoking and excessive exposure.” Collagen supplements can help stimulate natural collagen production, but they must be used in combination with a healthy lifestyle to achieve the best results.
Listen to your body When you notice signs of dry skin, joint pain or fragile hair and adopt a lifestyle that supports natural collagen production. No supplement can replace a balanced diet and a healthy lifestyle, which are essential for maintaining skin and joints.
