An egg by-product supplement built from the same materials as cartilage and skin. Its strongest claim is modest relief of knee pain and stiffness, appearing unusually fast at a small once-daily dose. How well it is tolerated is the clearest finding; egg allergy is the one real hazard. Almost every trial was funded by a seller. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Ovomucoid-specific immunoglobulin E | Undetectable (<0.35 kU/L) | Identifies the one population at real risk |
| High-sensitivity C-reactive protein | <1.0 mg/L | Tracks whether systemic inflammation contributes to joint pain |
| Urinary CTX-II | No established target; track change from the individual's own baseline | Only available readout of cartilage breakdown rate |
| Serum uric acid | 3.5–5.5 mg/dL | Separates gout from osteoarthritis as the pain source |
| 25-hydroxyvitamin D | 40–60 ng/mL | Deficiency independently causes diffuse joint and muscle pain |
| Comprehensive metabolic panel with eGFR | Alanine aminotransferase <25 U/L; eGFR >90 mL/min/1.73 m² | Confirms no organ signal over long use |
Cadence: Symptom scores at 2, 4 and 8 weeks, then every 3–6 months if use continues; laboratory testing repeated only at 6–12 months or if symptoms change
