Peptide Fortified Collagen Original Body Boost Blend
Also known as: Hydrolyzed Collagen, Collagen Hydrolysate, CP, HC, Collagen Peptides
Overview
Collagen peptides are short chains of amino acids derived from the enzymatic hydrolysis of collagen, primarily from animal connective tissues (e.g., bovine, porcine, fish). This process makes them more bioavailable than native collagen. They are rich in glycine, proline, and hydroxyproline, which are crucial amino acids for endogenous collagen synthesis in the body. As a nutraceutical supplement, collagen peptides are primarily used to support skin health by improving hydration and elasticity, and to enhance musculoskeletal health, including joint support, muscle adaptation, and recovery from exercise. While there is strong evidence for skin benefits, their impact on musculoskeletal performance is less consistent. Research on collagen peptides is extensive, with numerous randomized controlled trials (RCTs) and systematic reviews available, indicating a moderate to high level of research maturity.
Benefits
Collagen peptide supplementation offers several evidence-based benefits, with varying strengths of evidence. For skin health, systematic reviews of 26 RCTs involving over 1700 participants consistently demonstrate significant improvements in skin hydration and elasticity after at least 8 weeks of daily supplementation (p < 0.00001). These benefits are statistically significant with moderate effect sizes, making collagen peptides a valuable supplement for individuals concerned with skin aging. For musculoskeletal health, meta-analyses suggest that collagen peptide supplementation, particularly when combined with resistance training, may improve muscle mass and tendon adaptation. However, effects on maximal strength are often inconsistent and statistically non-significant (SMD=0.079, p=0.445). Some evidence also points to improved recovery from exercise-induced damage and enhanced functional recovery. These musculoskeletal benefits are most relevant for healthy adults, including recreational athletes, and require concurrent exercise and longer durations (≥8 weeks) to manifest. While skin benefits are well-established, the evidence for significant performance-enhancing effects in muscle strength is weaker.
How it works
Collagen peptides exert their effects primarily by providing a readily available source of specific amino acids—glycine, proline, and hydroxyproline—which serve as essential building blocks for endogenous collagen synthesis. Once ingested, hydrolyzed collagen is rapidly absorbed into the bloodstream as di- and tri-peptides, detectable within two hours. These peptides then stimulate fibroblasts and other cells to produce new collagen in various tissues, including skin, muscles, tendons, and ligaments. In the context of musculoskeletal health, collagen peptides interact with body systems by enhancing extracellular matrix remodeling and stimulating anabolic signaling pathways (such as PI3K-Akt, MAPK, and mTOR) when combined with resistance training. This promotes myofibrillar protein synthesis and supports connective tissue repair mechanisms, contributing to tissue integrity and recovery.
Side effects
Collagen peptides are generally regarded as safe, with a low incidence of adverse effects reported in clinical trials. The most commonly reported side effect, though rare, is mild gastrointestinal discomfort, which may include bloating or a feeling of fullness. No serious adverse effects have been consistently documented. Allergic reactions are possible but rare, primarily occurring in individuals with pre-existing allergies to the specific animal source of the collagen (e.g., fish or bovine). There are no significant drug interactions documented with collagen peptide supplementation. Contraindications are limited to individuals with a known allergy to collagen or its source. Data on the safety of collagen peptides in special populations, such as pregnant or lactating women, are limited, and caution is advised in these groups. Overall, collagen peptides have a favorable safety profile for most healthy individuals.
Dosage
The recommended dosage for collagen peptides varies depending on the desired outcome. For skin benefits, a minimum effective dose of approximately 2.5 grams per day has been shown to be effective. For musculoskeletal health, including muscle and tendon adaptation, studies typically use higher doses, ranging from 10 to 15 grams per day. The optimal dosage range generally falls between 2.5 and 15 grams per day. Doses up to 15 grams per day have been well-tolerated in studies, with insufficient data to establish a maximum safe dose beyond this range. Collagen peptides are typically taken daily, often with or after meals. For musculoskeletal benefits, some protocols suggest combining intake with exercise. Hydrolyzed collagen peptides are the preferred form due to their enhanced bioavailability. While vitamin C is a cofactor for collagen synthesis, its co-ingestion is not always necessary as part of the supplement, and evidence for enhanced absorption with it is limited.
FAQs
Is collagen peptide supplementation effective for skin aging?
Yes, strong evidence from multiple studies supports that daily collagen peptide supplementation significantly improves skin hydration and elasticity after 8 weeks of consistent use.
Does collagen peptide supplementation improve muscle strength?
Current research indicates that collagen peptides do not significantly improve muscle strength beyond the effects of exercise alone, although they may aid muscle and tendon adaptation.
How long does it take to see effects from collagen peptides?
Skin benefits typically become noticeable after 6-8 weeks of daily supplementation. Musculoskeletal effects, if any, usually require longer durations and concurrent exercise.
Is collagen peptide supplementation safe?
Yes, collagen peptides are generally considered safe with a very low incidence of mild side effects, primarily rare gastrointestinal discomfort. Allergic reactions are uncommon.
Can collagen peptides replace dietary protein intake?
No, collagen peptides are not a complete protein as they lack some essential amino acids. They should be considered a supplement to, not a replacement for, adequate dietary protein.

The findings suggest that while other musculoskeletal benefits might exist, strength gains are not consistently supported.
- https://ciss-journal.org/article/view/11516 – This meta-analysis indicated that collagen peptides combined with resistance training can activate anabolic pathways and potentially increase muscle mass. However, it noted that the effects on strength were equivocal, highlighting the complexity of its mechanisms.
