Dear Friends,
If you’ve ever hard-boiled an egg and peeled away the shell, you may have noticed a thin film lining the inside of the shell.
That film is called the eggshell membrane.
And although most of us would never think to eat it, this membrane is actually a nutritional powerhouse that your joints — and even your skin — can really benefit from.
So today, I want to review the Natural Eggshell Membrane ingredient known as NEM®, and why I think it is one of the most interesting and underappreciated ingredients in the joint health category.
Because when many people think about joint supplements, they think about things like glucosamine or chondroitin. But eggshell membrane is different.
It’s not just one isolated compound.
It’s a naturally occurring matrix that contains many of the same compounds found in the body’s own connective tissue — including collagen, hyaluronic acid, chondroitin sulfate, and other glycosaminoglycans, including a small amount of glucosamine, and proteins important for healthy joints.
That’s a big reason why joints love it.
Turning Waste into Joint Support
Now, before we get into the science, there’s also a great origin story here.
In the United States, we consume an enormous number of eggs every year, and a large amount of the shells and membranes typically end up as waste.
A significant percentage of eggs are cracked at commercial facilities, and traditionally much of that material went to landfills.
The founders of Stratum Nutrition saw an opportunity in that waste stream.
They developed a patented process using steam and vibration to separate the eggshell from the delicate membrane and turn it into a useful nutritional ingredient.
The shell could be upcycled into calcium, and the membrane could be concentrated into a powder for joint health.
That’s how NEM® was born.
So it’s a very unusual ingredient. It’s natural. It’s food-sourced. It’s upcycled. And it’s backed by real human research.
Strong Research Backing
One of the things I like most about NEM® is that it combines a compelling nutritional profile with unusually strong scientific support.
To date, 16 research studies with NEM® have been published investigating both safety and efficacy, including trials in people with joint discomfort, as well as in healthy people dealing with exercise-related joint stress.
And importantly, the effective dose is very practical - just 500mg a day.
Study after study has shown meaningful benefits for joint discomfort, stiffness, flexibility, and cartilage protection.
Now let’s talk about what makes NEM® so appealing in the real world. One big advantage is that it can start helping relatively quickly.
Research studies with NEM® have shown improvements in joint comfort and flexibility in as little as 7 to 10 days.
That’s important because many joint ingredients ask people to wait much longer.
With NEM®, there’s evidence that it can start making a difference in how your joints feel within days — especially when it comes to joint discomfort and stiffness.
And with continued use, the benefits can continue to improve over time.
So this is not just about fast support. It’s also about sustained support.
Works in Multiple Ways
Now, one reason NEM® may work so well is because it appears to help in more than one way.
First, it provides many of the building blocks and bioactive compounds naturally found in joint tissue.
As I mentioned, it contains collagen, hyaluronic acid, chondroitin sulfate, and related compounds.
These are the types of substances found in cartilage, synovial tissue, ligaments, and tendons.
Second, NEM® can help support a healthy inflammatory response.
That matters because a lot of joint discomfort and stiffness are tied to how the body responds to daily wear and tear.
The NEM® research materials include studies showing that eggshell membrane may help reduce pro-inflammatory mediators and support healthy levels of markers associated with inflammation, including C-reactive protein (or CRP) in certain research settings.
And third, NEM® has been shown to help protect healthy joint cartilage.
This is one of the most interesting parts of the science.
Researchers have looked at a marker called CTX-II, which is a biomarker of type II collagen degradation.
Type II collagen is the predominant collagen found in cartilage. When cartilage breaks down, fragments of this collagen can be released and later detected in urine.
A reduction in urinary CTX-II is considered a sign that cartilage breakdown is being reduced.
That means NEM® is not just about how your joints feel. It may also help support the structural integrity of healthy cartilage over time.
And to me, that’s a very important distinction. Because ideally, a joint ingredient should do more than just make you feel a little better temporarily.
It should also help support the tissues your joints depend on.
That’s where NEM® really stands out.
Helps You Stay Active
One of the newer and more interesting areas of research involves exercise-induced joint discomfort and stiffness.
This is important because joint support is not just for older adults with worn joints. It also matters for active adults.
In healthy postmenopausal women, NEM was shown to reduce exercise-induced stiffness, improve recovery, and have a beneficial effect on CTX-II, suggesting protection against exercise-related cartilage breakdown.
The NEM research literature also highlights that healthy-person trials are especially valuable because they show how an ingredient may help support joint health and maintain mobility before a person necessarily has a significant joint problem.
I like that a lot because the smartest joint strategy is not to wait until everything hurts.
It’s to support your joints proactively — whether you’re aging, staying active, exercising regularly, or just trying to keep moving comfortably.
And this is exactly why we include NEM® in TrueJoint FLX.
TrueJoint FLX is our most powerful joint formula, and NEM® is one of the key research-backed ingredients in it.
It fits beautifully because it helps address some of the main things people care about most: joint comfort, stiffness, mobility, flexibility, and support for healthy cartilage, collagen, and connective tissue.
That’s a very strong foundation for a joint formula. And I also love the environmental side of the story.
Millions of Eggshells Upcycled
NEM® is made from eggshell membranes that would otherwise have been discarded.
If you’re curious, it takes the eggshell membranes from about 12 eggs to make a single 500mg daily dose of NEM®.
To date, over 250 million pounds of eggshells have been diverted from landfills to make the NEM® powder.
So this is an example of taking something that once went to waste and turning it into a meaningful health ingredient.
That’s good for the environment. And good for our joints.
So to summarize:
Natural Eggshell Membrane, or NEM®, is a unique ingredient derived from the thin membrane inside eggshells.
It naturally contains compounds like collagen, hyaluronic acid, and chondroitin sulfate that are also found in healthy joint tissue.
At a practical dose of 500mg a day, it has been shown in research to help reduce joint discomfort and stiffness, improve flexibility, and help protect healthy cartilage.
And it may begin making a difference in as little as 7 to 10 days.
That’s why your joints love eggshell membrane.
It’s not just a nice story. It’s a naturally complete, research-backed ingredient that supports your joints from multiple angles.
Yours for Good Health,
