What is eggshell membrane?
When you crack an egg, there's a thin white film stuck to the inside of the shell. That's the eggshell membrane. This joint supplement is extracted from that film.
The membrane is similar in makeup to the cartilage in your joints. It contains small amounts of several cartilage components at once (glucosamine, chondroitin, hyaluronic acid, collagen and more).
Eggshell membrane benefits: where it may help
- Joint building blocks: It supplies several cartilage components together.
- Inflammation control: Research has looked at how it reduces excess release of the substances your body uses to send inflammation signals (cytokines).
- Pain and stiffness: In studies using 250 mg and 500 mg a day, pain, stiffness and walking ability all improved.
It's an ingredient with active recent research and a growing number of clinical trials (studies in people). However, there are still no head-to-head studies showing it works better than a high dose of a single ingredient like glucosamine.
Who it suits / who should try something else first
It's a good fit if:
- □ Your knees, fingers or ankles ache or hurt
- □ Your joints feel stiff when you wake up
- □ You can feel your joints weakening with age
- □ You're an older adult looking to pick one joint supplement
See a doctor first if you have:
- A herniated disc in your back: This is a structural problem where the cushion between the bones has slipped out, so a supplement is unlikely to fix it. Get medical care first.
Eggshell membrane daily dose
| Goal | Daily dose |
|---|---|
| Steady maintenance | 250 mg |
| More active support for pain | 500 mg |
Studies found benefits starting at 250 mg. Take it once a day, at the same time every day.
How to choose eggshell membrane: look for NEM
- Make sure the ingredient is "NEM" — It's the eggshell membrane ingredient with the most research behind it. It's also been officially recognized for joint function in some countries.
- Don't be fooled by similar names like DEM or PEM — The names look alike, but they're different ingredients.
- Check how many mg are in each capsule — See whether it's 250 mg or 500 mg and match your daily amount.
Good pairings
A common basic stack for joint support is eggshell membrane + omega-3 + MSM.
| Ingredient | What it does |
|---|---|
| Eggshell membrane | Cartilage building blocks + inflammation control |
| Omega-3 | Whole-body inflammation support |
| MSM | Joint pain and inflammation support |
| Curcumin, boswellia | When you want extra inflammation support |
Start with eggshell membrane alone, and if it's not enough, add one at a time.
Combinations
Works well with: Omega-3, MSM (Methylsulfonylmethane), Curcumin (Turmeric), Boswellia
Frequently asked questions
How much eggshell membrane should I take a day?
Studies used 250 mg or 500 mg a day. Take 250 mg for maintenance, or 500 mg if you have pain and want more active support.
Can I just eat the membrane from eggshells?
Don't expect much from it. The molecules are large, so eating it as-is means almost none gets absorbed. Take a hydrolyzed supplement instead.
What's the difference between NEM and DEM?
Both are names of eggshell membrane ingredients, but they're different ingredients. NEM has the most research behind it, so look for NEM on the label.
Which is better, eggshell membrane or glucosamine?
Eggshell membrane contains small amounts of several cartilage components and also aims to control inflammation. But no studies have compared the two directly yet. Pick one and take it consistently.
Does eggshell membrane help a herniated disc?
A herniated disc is a structural problem, so a supplement is unlikely to fix it. Get medical treatment first.
