It’s easy to focus on the specifics of a health problem but lose sight of the big picture. Components of the body’s systems are best understood in the context of relationships with each other, rather than in isolation. Improvement in one area of a system can adversely affect another.  With a systems approach, we help you avoid the silo effect by treating the parts in relation to the whole. And treating the systemic problem can help prevent a host of other health issues related to the very same problem. Read more about our systems approach based on allostatic load theory.

Laser Focus versus Hit or Miss

You don’t need an arsenal of products—one for each symptom—but rather a small, calculated set of supplements, laser focused on treating the underlying cause.  That makes treatment simpler and patient compliance easier.


All of our products are backed by a body of published research, as well as reports from top, highly experienced clinicians to ensure they truly assist in the optimization of health. For example, our SarcoSelect formula is directly based on an important study regarding sarcopenia and building muscle mass in cancer patients. Please contact us to learn more about the research behind our product formulations.


Our strict adherence to every aspect of Good Manufacturing Practices (GMP’s) outlined by the FDA is just one example of our commitment to the highest standards of quality, from ingredient procurement to packaging. Learn more about our quality.


Don’t just take our word for it—see for yourself. We encourage you to compare Moss Nutrition with other supplements, and if you don’t see significantly improved results, simply return any unsold inventory from your initial purchase within 60 days and we’ll refund the price of that inventory.

Don't compete with online retailers. You can’t win—unless you’re selling supplements that aren’t sold there. Our promise to you is that you’ll never see our products on retail websites or in pharmacies.

Let’s look at this from another angle

That’s how Dr. Jeffrey Moss has approached nutritional and functional medicine for more than a quarter century. The breakthrough came with the realization that you don’t need separate products for every complaint.  There’s a common thread among most health conditions that allows you to treat them all with a strict set of products focused on the underlying cause.  It all fits into a unique paradigm where everything is interrelated.  And by treating the system as a whole, you can also prevent other complaints related to the very same cause.

Thus, the Systems Approach to Functional Medicine was born.  And that seismic shift in thinking has been brought to life with the Moss Nutrition Select product line.
