Eggshell membrane (NEM)

Tier 2 — promising · Joint · Connective tissue · Collagen

The translucent membrane lining the inside of chicken eggshells, supplied as a partially hydrolysed powder (Natural Eggshell Membrane, NEM). It supplies type I, V, and X collagen, glycosaminoglycans (hyaluronic acid, chondroitin), and elastin — a composition matching joint and connective-tissue ECM. Multiple RCTs show improvements in joint pain, stiffness, and flexibility within 7-10 days at 500 mg/day — faster than glucosamine/chondroitin. Shellfish-free alternative to marine-sourced joint supplements. Avoid with egg allergy.

Dose: 500 mg NEM daily (standardised Natural Eggshell Membrane)
