Collagen; Hydrolyzed

Also known as: collagen peptides, collagen hydrolysate, gelatin hydrolysate, hydrolyzed gelatin, Hydrolyzed Collagen

Overview

Hydrolyzed collagen is a bioactive peptide derived from collagen-rich animal sources, such as bones, hides, and skin, through a process known as hydrolysis. This process breaks down collagen into smaller, more bioavailable peptides and amino acids, making it easier for the body to absorb. Hydrolyzed collagen is widely utilized in nutricosmetics and dietary formulations aimed at enhancing skin health, improving hydration, elasticity, and reducing signs of aging, particularly wrinkles. Its effectiveness is attributed to key bioactive peptides, including Pro-Hyp, Hyp-Gly, and Gly-Pro-Hyp. Supported by numerous randomized controlled trials and systematic reviews, hydrolyzed collagen is gaining popularity for its potential benefits in contemporary skincare regimens.

Benefits

Research shows that hydrolyzed collagen supplementation significantly enhances skin hydration and elasticity while reducing wrinkle visibility. Systematic reviews indicate that participants consuming hydrolyzed collagen report marked improvements in skin hydration compared to placebo groups. Particularly beneficial for women aged 20 to 70, clinical studies reveal that consistent users see noticeable improvements in skin quality within 12 to 24 weeks, with effect sizes ranging from moderate to large. This evidence-backed approach highlights hydrolyzed collagen as a viable intervention for combating aging skin and promoting overall skin health.

How it works

Upon ingestion, hydrolyzed collagen is absorbed in the gastrointestinal tract, where it is broken down into smaller bioactive peptides that enter systemic circulation. These peptides stimulate collagen synthesis in fibroblasts and engage with collagen-producing cells, thus supporting the extracellular matrix. This action enhances skin hydration and elasticity by promoting moisture retention and overall skin health.

Side effects

Hydrolyzed collagen is largely considered safe for the general population, with minimal documented adverse effects. Allergic reactions are rare, but individuals with sensitivities to bovine, marine, or related sources should exercise caution. Currently, no significant drug interactions have been reported, making it a low-risk supplement. However, pregnant and breastfeeding women should seek advice from healthcare professionals before starting supplementation. Overall, reported prevalence of side effects is low, with literature indicating no significant or severe adverse events associated with its intake.

Dosage

The recommended dosage of hydrolyzed collagen typically ranges from 2.5g to 10g per day, with the minimum effective dose cited at approximately 2.5g. Studies often assess dosages between 5g and 10g to evaluate optimal outcomes. While no specific upper limit has been firmly established, daily amounts exceeding 10g are seldom addressed in the literature. Consistent daily intake is essential for achieving potential benefits, and the timing of consumption is generally believed to have minimal influence on effectiveness. Hydrolyzed collagen is available in various forms such as powders, capsules, and tablets, all maintaining efficacy provided they deliver adequate amounts of bioactive peptides.
