Detailed Description
Collagen is characterized by its high content of glycine, proline and hydroxyproline, and it is found to exert beneficial effects on several health benefits. Recent evidence suggests that the consumption of amino acids and/or peptides abundantly present in collagen may have the capacity to influence the synthesis of new collagen in the body. Indeed, it has been found that collagen supplements improve skin moisture, elasticity, and hydration when orally administered. Additionally, collagen reduces the wrinkling and roughness of the skin, and existing studies have not found any side effects of its oral supplements. Thus, to exert any beneficial effects, it is essential that hydrolyzed collagen is optimally absorbed. This study aimed to investigate the postprandial absorption of collagen and elucidate the absorption rate and bioavailability after oral intake.
The study personnel will prepare the drinkable solutions containing the study products in a room accessible to site staff only. Drinkable solutions will be provided to subjects just before consumption. Product ingestion will be early in the morning after overnight fasting for 12 h. On the morning of the experiment, subjects will fast and each subject will take the products orally. Dosage (Quantity of product to consume orally): This is calculated depending on the body weight; 400 mg/kg of body weight with 20 w/v % water. Collagen products (fine powder) will be diluted in water prior consumption. Control group ingest approximately same amount of plain water. Participants cannot drink water within 4 hours before and after the product consumption.
The assessment of the bioavailability of the four collagen-based treatments (CP1, CP2, CP3, CP4) will be evaluated by quantifying 8 di/tri-peptides and the amino acid profile in the blood of 25 volunteers by LC-MS.

Upon oral intake, blood samples will be obtained by digital puncture at time 0 minutes (before consuming the product), and 15 minutes, 30 minutes, 120 minutes and 240 minutes after consuming the product. The digital puncture will be performed with Verifine Safety Lancets, and the blood will be collected in MiniCollect tubes. Blood samples will be centrifuged (1000 rpm, 5 minutes, 4ºC) and plasma will be collected. The profile of single amino acids and selected di- and tripeptides will be determined in the plasma samples by mass spectrometry (LC-MS) and the change in the levels of these molecules will be assessed in the specified time points. The following molecules will be analyzed:
