Hydrolyzed collagen is a processed form of collagen protein derived from animal sources, designed for improved absorption. It is marketed for various health benefits, including skin health, joint pain relief, bone health, and muscle support. While research suggests potential benefits in these areas, further investigation is needed to confirm these effects definitively. Common side effects are mild, primarily involving gastrointestinal discomfort, but allergic reactions are possible. Individuals with known allergies to animal products should exercise caution.
Key Information
Outside Body Harmful Score
Common Dosage
2.5-15g daily
Source Type
natural
Production Process
Collagen is extracted from animal sources (bovine, porcine, or marine) and then broken down via hydrolysis, using enzymes or acids, into smaller peptides. This process makes the collagen more bioavailable for absorption.
Use Type
Outside BodyPotential Benefits
Enhances bone density, strength, and integrity by supporting bone formation, calcium absorption, and reducing age-related bone loss. Improves overall skeletal health and function, ultimately reducing the risk of fractures.
This benefit aims to improve overall skin health and appearance through increased hydration, reduced inflammation, improved elasticity, and protection from environmental damage. Healthy skin exhibits a smooth texture, even tone, and strong barrier function.
Reduces joint pain by targeting inflammation, supporting cartilage, and modulating pain signals, leading to improved mobility and quality of life. This can be achieved through a variety of methods.
Hydrolyzed collagen may improve skin elasticity, hydration, and reduce the appearance of wrinkles by stimulating collagen production in the skin. It works by providing building blocks that encourage fibroblasts to create more collagen, elastin, and hyaluronic acid.
Hydrolyzed collagen, combined with resistance training, supports muscle protein synthesis, leading to increased muscle mass and strength. Its bioavailability enhances absorption and potentially accelerates muscle recovery.
Possible Side Effects
Allergic reactions are hypersensitivity responses to allergens, ranging from mild skin irritation to life-threatening anaphylaxis. Symptoms vary widely and are caused by an immune response.
Gastrointestinal issues include nausea, diarrhea, abdominal discomfort, and vomiting, potentially stemming from altered gut motility, microbiota changes, or irritation. While often mild, persistent symptoms necessitate evaluation, and contributing factors like pre-existing conditions should be considered.
Collagen peptide consumption can sometimes result in an unpleasant taste or odor, varying in intensity and type depending on the source and individual sensitivity. This taste is generally harmless but may be bothersome to some users.
Mild gastrointestinal issues may involve bloating, heartburn, or diarrhea. These side effects are generally not severe but can cause discomfort.
Certain supplements, like fish oil, can cause a fishy or metallic aftertaste due to oxidation or compound breakdown. This taste usually resolves on its own and can be minimized by proper storage.
