Hydrolyzed Chicken Collagen Eggshell Membrane Powder
Also known as: Hydrolyzed collagen, collagen peptides, natural eggshell membrane, NEM®, Hydrolyzed Chicken Collagen Eggshell Membrane Powder
Overview
Hydrolyzed Chicken Collagen Eggshell Membrane Powder is a joint health nutraceutical combining two distinct components: hydrolyzed chicken collagen and eggshell membrane (ESM) powder. Hydrolyzed chicken collagen is derived from chicken connective tissues and skin, enzymatically broken down into smaller peptides for enhanced absorption. Eggshell membrane powder is obtained from the thin layer lining the inside of chicken eggshells, primarily composed of collagen types I, V, and X, glycosaminoglycans, and other proteins, often partially hydrolyzed to improve bioavailability. This combination is primarily used to support joint health, reduce symptoms associated with osteoarthritis (OA) such as pain and stiffness, and improve overall joint function. The bioactive peptides and proteins present in this supplement are believed to stimulate cartilage repair and reduce inflammation. Research on both components, especially ESM, is moderately mature, with multiple randomized controlled trials (RCTs) and meta-analyses supporting their efficacy in managing knee OA symptoms. While individual components have strong evidence, emerging research supports the benefits of their combined use.
Benefits
The primary benefit of Hydrolyzed Chicken Collagen Eggshell Membrane Powder is its significant potential to reduce knee osteoarthritis (OA) pain and improve joint function. A 2024 systematic review and meta-analysis of 7 RCTs on eggshell membrane showed a moderate effect size for pain reduction (SMD −0.23) and improvement in total WOMAC score (effect size −0.34), indicating statistically significant and clinically meaningful symptom relief. Hydrolyzed collagen, while showing variable effects depending on its peptide composition, generally contributes positively to joint health by potentially improving cartilage metabolism and reducing OA symptoms. These benefits are most evident in adults with knee osteoarthritis. Secondary effects include potential anti-inflammatory properties. The effect sizes are generally small to moderate but are statistically significant, suggesting tangible relief for individuals. Benefits typically manifest after several weeks to months of consistent supplementation, with longer durations (e.g., over 10 months) potentially yielding greater improvements.
How it works
The mechanism of action for Hydrolyzed Chicken Collagen Eggshell Membrane Powder involves the synergistic effects of its bioactive components. Bioactive peptides from hydrolyzed collagen and eggshell membrane are absorbed in the small intestine and are believed to stimulate chondrocyte activity. Chondrocytes are the cells responsible for maintaining cartilage, and their activation promotes the synthesis of type II collagen and other extracellular matrix components, crucial for cartilage repair and regeneration. This supplement also modulates inflammatory pathways within the joints, leading to a reduction in pro-inflammatory cytokines, which are key contributors to pain and degradation in conditions like osteoarthritis. The glycosaminoglycans present in eggshell membrane further contribute to the integrity of the cartilage matrix. The effectiveness is influenced by the specific peptide composition and the degree of hydrolysis, which impacts absorption and bioavailability.
Side effects
Hydrolyzed Chicken Collagen Eggshell Membrane Powder is generally regarded as safe, with a low incidence of adverse effects reported in clinical trials. Common side effects are not consistently reported, and most individuals tolerate the supplement well. Uncommon side effects, occurring in 1-5% of users, may include mild gastrointestinal discomfort such as bloating or stomach upset. Rare side effects, occurring in less than 1% of users, are primarily allergic reactions, particularly in individuals with pre-existing allergies to eggs or chicken protein. These reactions could manifest as hives, swelling, or difficulty breathing. There are no significant drug interactions reported with this supplement. However, it is contraindicated for individuals with known allergies to eggs or chicken-derived products. Special caution should be exercised in egg-allergic individuals due to the eggshell membrane component. Overall, the safety profile is favorable when used within recommended dosages.
Dosage
For optimal benefits, the typical dosage for eggshell membrane (ESM) ranges from 300 mg to 500 mg daily. For the hydrolyzed chicken collagen component, doses often range from 5 to 10 grams daily. There is no established maximum safe dose, as doses used in clinical trials have generally been well tolerated without significant adverse effects. For best absorption and efficacy, it is recommended to take the supplement daily, potentially with meals. The form of the supplement can vary, with powder being common, but capsules and tablets are also available. The hydrolysis process is crucial as it enhances the bioavailability of the peptides, and the specific peptide composition significantly influences the supplement's bioactivity. While not always explicitly required, Vitamin C is known to enhance collagen synthesis and may be a beneficial cofactor.
FAQs
Is it safe for long-term use?
Yes, current evidence from clinical trials and reviews supports the safety of long-term use of hydrolyzed chicken collagen and eggshell membrane powder at recommended dosages.
How soon can I expect to see results?
Symptom improvement typically begins within 4 to 12 weeks of consistent daily supplementation, with more significant benefits potentially observed after several months.
Can this supplement replace my prescribed osteoarthritis medications?
No, this supplement is intended as an adjunct therapy to support joint health and manage symptoms, not as a replacement for prescribed medications for osteoarthritis.
Does eggshell membrane powder contain allergens?
Yes, individuals with allergies to eggs or chicken protein should exercise caution, as eggshell membrane powder is derived from eggs and may contain residual egg proteins.
Is hydrolyzed chicken collagen the same as bovine collagen?
No, while both are collagen, their peptide profiles differ based on the source. This means their specific effects and bioactivity can vary, making product standardization important.
Research Sources
- https://pmc.ncbi.nlm.nih.gov/articles/PMC11356944/ – This systematic review and meta-analysis from 2024, including 7 RCTs, found that eggshell membrane supplementation significantly reduced pain (SMD −0.23) and improved total WOMAC scores (effect size −0.34) in patients with knee osteoarthritis. The study concluded that eggshell membrane is a safe and well-tolerated option for managing OA symptoms, though it noted moderate heterogeneity among studies and a need for longer-term research.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10058045/ – This narrative review from 2023 discusses the biological activity of collagen supplementation, emphasizing that the efficacy of hydrolyzed collagen depends heavily on its specific peptide composition. It highlights that not all hydrolyzed collagens effectively stimulate type II collagen synthesis and stresses the need for better standardization of products to ensure consistent therapeutic effects.
- https://www.nature.com/articles/s41598-020-78075-x – This meta-analysis from 2020, which included 42 RCTs on various nutraceuticals for osteoarthritis, found that supplements including collagen showed modest improvements in WOMAC pain (SMD −0.36) and stiffness. It also suggested that longer supplementation durations (over 10 months) were associated with greater benefits, though the study was not specific to chicken collagen or eggshell membrane and included mixed supplement types.
