Quality Nutrition never Tasted So Delicious!

Collagen is a protein found in your body that is used to make connective tissue. It is the primary building block of your body’s skin, muscles, bones, tendons, ligaments, and other connective tissues. It’s also found in your organs, blood vessels and intestinal lining.

Your body produces less collagen as you age, and existing collagen breaks down at a faster rate. The collagen is also lower in quality than when you were younger. Women experience a significant reduction in collagen production after menopause.

Collagen can’t be measured — for instance, in a blood test — but there are signs that your collagen level is decreasing – wrinkled skin, hallowing in and around your eyes and face, weakening muscles, stiffer, less flexible tendons and ligaments, joint pain or osteoarthritis and more.

Here you can place an explanation or answer to the question.

Collagen in foods can’t be absorbed by your body in its whole form. Your body breaks down the collagen proteins you eat into amino acids. So eating collagen-rich foods doesn’t directly result in higher collagen levels in your body.

Collagen first appeared as an ingredient in skin creams and serums. However, its effectiveness as a topical application was doubted even by dermatologists, as collagen is not naturally found on the skin’s surface but in the deeper layers. Applied topically, collagen fibers are too large to permeate the skin’s outer layers. This is why oral collagen peptides supplements in the form of pills or powders are believed to be more effectively absorbed by the body.

Collagen peptides are small pieces of animal collagen. Collagen can’t be absorbed in a whole form and it has to be broken down into smaller pieces called peptides. Collagen peptides are absorbed through your gastrointestinal tract, then released in the blood and eventually reach the skin and other organs.

Yes. Some research on collagen supplements is related to skin, nails, joints health as well as overall body composition and body strength. Randomized controlled trials have found that collagen supplements improve skin elasticity. Other trials have found that supplementing with collagen peptides can improve joint mobility and decrease joint pain such as with osteoarthritis or in athletes. More information can be found below.

Some research shows that collagen peptide supplementation in combination with resistance training improved body composition and increased muscle strength. Resistance training alone has proven to do that, but the studies suggested that the effect is better pronounced in those who supplemented with collagen peptides.

Participants: female, age 35-55 years.

The objective of this research was to understand the effectiveness of collagen peptides on skin biophysical parameters related to cutaneous aging. In this clinical trial, 69 female ages 35-55 years received 2.5 grams or 5.0 grams of collagen peptides or placebo (a substance that has no therapeutic effect) once daily for 8 weeks, with 23 female being allocated to each treatment group. Skin elasticity, skin moisture, trans-epidermal water loss and skin roughness were objectively measured before the first oral product application and after 4 and 8 weeks of regular intake. Skin elasticity (primary interest) was also assessed at follow-up 4 weeks after the last intake of collagen peptides. At the end of the study, skin elasticity in both collagen peptides dosage groups showed a statistically significant improvement in comparison to placebo. After 4 weeks of follow-up treatment, a statistically significantly higher skin elasticity level was determined in elderly women. With regard to skin moisture and skin evaporation, a positive influence of collagen peptides treatment could be observed in a subgroup analysis, but the data failed to reach a level of statistical significance. No side effects were noted throughout the study.

Participants: Middle-age male, untrained.

Another study has shown that collagen peptides combined with resistance training improves body composition and muscle strength in middle-aged, untrained men. In the exploratory part of the study, these results were compared with another group that had received whey protein in addition to the resistance training. Ninety-seven men completed this study and participated in a 12-week resistance training program. All participants were split into 3 groups. The first group ingested 15 grams of collagen peptides per day, the second was given placebo (a substance that has no therapeutic effect) and the third ingested 15 grams of whey protein daily. Changes in fat free mass and fat mass were determined by dual-energy X-ray absorptiometry, and isometric leg strength was measured. All participants had statistically significantly improved levels in fat free mass, decreased fat mass and improved leg strength. The main analysis revealed a statistically significantly higher increase in fat free mass and decrease in fat mass in the group that was supplemented with collagen peptides compared with the placebo group.

Participants: young active adults.

The aim of the study was to evaluate the use of collagen peptides in reducing pain in athletes with functional knee problems during sport. One hundred thirty-nine athletes with functional knee pain ingested 5 grams of collagen peptides or a placebo (a substance that has no therapeutic effect) per day for 12 weeks. The primary outcome of the study was a change in pain intensity during activity, which was evaluated by the participants and the attending physicians using a visual analogue scale. As secondary endpoints, pain intensity under resting conditions, the range of motion of the knee joint, and the use of additional therapeutic options were assessed. The results revealed a statistically significant improvement in activity-related pain intensity in the group that was supplemented with collagen peptides compared with placebo. The results were confirmed by the physician’s assessment. Pain under resting conditions was also improved, but no significance compared with placebo was detected. Due to the high joint mobility at baseline, no significant changes of this parameter could be detected. The use of additional treatment options was significantly reduced after collagen peptides intake. The study demonstrated that the supplementation of collagen peptides in young adults with functional knee problems led to a statistically significant improvement of activity-related joint pain.
