Collagen: The Secret to Skin Health, Not a Wrinkle Cure
Regular intake of collagen supplements can enhance skin health by increasing its elasticity and moisture levels. However, it won't help in eradicating wrinkles, according to a recent scientific assessment.
Researchers, following an extensive analysis, are assured that collagen supplements, in the form of pills or powder, can result in visible skin improvements over a period of time, but they're not an immediate solution.
Collagen's Potential Health Benefits
These supplements have also been observed to alleviate symptoms associated with wear and tear, including joint pain and stiffness from arthritis. This conclusion is based on the findings from 113 tests involving almost 8,000 participants.
Collagen, a naturally occurring protein in the body, diminishes with age. It plays a crucial role in reinforcing and supporting skin, nails, bones, and connective tissues such as tendons and cartilage.
Women experience a further loss of collagen around menopause, when their menstrual cycle ceases - approximately one-third of the body's collagen content is lost, as per the scientists who shared these findings in a recognized scientific journal.
Types of Collagen Supplements
Several types of collagen supplements are available, including marine, bovine, and vegan collagen. However, the review could not determine whether one kind was more effective than the others.
Researchers, mainly from Anglia Ruskin University, emphasize that a significant number of studies on supplements have been financed by the supplement industry. They noted that extravagant promises about collagen's anti-aging benefits have been made. The review was conducted independently, without any industry funding.
Findings and Recommendations
One of the main researchers, Prof Lee Smith, stated: "Our study compiles the most robust evidence currently available on collagen supplementation.
Collagen isn't a panacea, but consistent use over time can yield credible benefits, especially for skin health and osteoarthritis. Our research reveals clear advantages in essential areas of healthy aging while also debunking certain misconceptions about its usage."
The researchers propose positioning collagen as a comprehensive maintenance tool for aging and sun-damaged skin, rather than an anti-wrinkle treatment.
Smith added: "If we consider anti-aging as a product or method devised to hinder the visible signs of aging, then our findings support this claim for some aspects. For instance, better skin tone and moisture are linked with a more youthful appearance."
Natural Collagen Sources
"Vitamin C assists collagen formation, so it's beneficial to consume foods rich in this nutrient, such as citrus fruits, berries, green vegetables, peppers, and tomatoes. Zinc, found in meat, poultry, cheese, certain shellfish, nuts, seeds, and whole grains, also aids the body in collagen production.
Many collagen supplements and dietary collagen sources are derived from animal products, making them unsuitable for those following a vegan diet. However, the body can produce its own collagen from the amino acids present in dietary protein. Thus, protein from beans and lentils can provide the necessary amino acids for collagen production. Vegan-friendly supplements are also available."
