Introduction
Hydrolyzed collagen is a dietary supplement that has received a lot of attention in recent years. Presented as a miracle solution to slow aging, improve the appearance of the skin, strengthen joints or increase bone density, this product raises many questions about its real effectiveness and the arguments put forward by its promoters. In this article, we’ll decipher the marketing surrounding hydrolyzed collagen and examine the scientific evidence presented by its sellers.
What is collagen?
Collagen is a protein present in abundance in our body. It plays an essential role in the structure of connective tissues (skin, tendons, ligaments) and contributes to their mechanical resistance. With age, the natural production of collagen gradually decreases, leading to a weakening of the tissues concerned and favoring the appearance of wrinkles or osteoarthritis.
The promises of hydrolyzed collagen
In the form of powder or capsules to be ingested daily, hydrolyzed collagen is presented as a simple solution to compensate for this natural decrease in protein levels in our body. Manufacturers and sellers of collagen supplements tout beneficial effects on skin, joints and bone density, often relying on scientific studies to support their arguments.
Efficiency called into question
However, it is important to note that these studies are often conducted by the companies themselves or financed by them. Furthermore, some of them present significant methodological weaknesses which limit their scope. For example, the use of small samples or the absence of a control group makes it difficult to generalize the results obtained.
Many medical experts and scientists have expressed reservations about the effectiveness of hydrolyzed collagen as a dietary supplement. Indeed, ingesting collagen does not necessarily guarantee that it will be assimilated and used by our body to strengthen our connective tissues. The digestive process can break down ingested collagen into individual amino acids which are then reused according to the body’s specific needs.
Expert Testimonials
“There is no strong evidence that taking collagen in supplement form will directly improve the health of your skin,” says Dr. Rajani Katta, a board-certified dermatologist and clinical professor at Baylor College of Medicine.
“Studies that show benefit are typically small, low quality and industry-funded,” says Dr Pieter Cohen, a GP at Cambridge Health Alliance and assistant professor of medicine at Harvard Medical School.
Deceptive advertising practices
Faced with these criticisms, some manufacturers do not hesitate to use aggressive marketing strategies to promote their products. For example, doctored before/after photos or embellished user testimonials can be used to give a false positive image of hydrolyzed collagen.
In addition, it is common for sellers to promote certifications or labels which do not actually guarantee any particular quality. Some products are even presented as “approved” by official organizations even though no independent evaluation process has been carried out.
Conclusion
In summary, while hydrolyzed collagen may seem appealing to those looking to slow the effects of aging on their skin and joints, it is important to keep a critical eye on the promises made by sellers and the scientific studies presented. Medical experts instead recommend focusing on a balanced and varied diet as well as good hydration to maintain the health of our skin and connective tissues.
