What is known

Each outcome with its grade (how strong the evidence is, A to D), the size of the effect where the entry records one, and how often studies agree.

What is uncertain

Read off the same rows as above. Nothing here is added that the entry does not itself record.

  • Thin evidence: Joint pain / stiffness (grade C).

The evidence in words

What it is

Natural eggshell membrane (NEM) supplies collagen, hyaluronic acid, and glycosaminoglycans for joints.

How it works

It provides connective-tissue substrates and may have anti-inflammatory effects.

What the evidence shows

Small trials (often manufacturer-linked) show reduced joint pain and stiffness at 500 mg/day within weeks; independent replication is limited. Modest and low-risk.

Safety & interactions

Safe; egg-allergy caution.

Bottom line

A convenient once-daily joint option with modest, mostly industry evidence. Reasonable to trial for OA.
