What It Does

Formulated by Dr. Kevin Passero, Durable MAGNESIUM features 300 mg of the superior magnesium glycinate form, which is a highly effective, chelated version of this essential mineral. Unlike other common forms, it's gentle on the digestive system and much better absorbed into the bloodstream, providing maximum cellular benefits and helping to quickly resolve deficiencies. This is critically important because many magnesium supplements are not properly absorbed by the body, providing little to no benefit.*

Why It Works

After 20+ years seeing patients in his clinic, Dr. Passero has analyzed the results of thousands of blood tests. When he reviews these results with his patients, many of them are surprised to learn they are deficient in magnesium. In fact, studies show that up to 45% of Americans are deficient in magnesium.*

This is unfortunate because every cell in your body needs magnesium to thrive and it is involved in over 300 essential biochemical processes, including energy production, DNA and protein synthesis and cell signaling. Magnesium also plays a critical role in maintaining heart rhythm, blood pressure balance, strong muscles, brain and nervous system health, bone density, circulatory health and more.*

Are You Magnesium Deficient? Here Are Some Common Signs
While a blood test is the very best way to find out if you are deficient, you may be able to get an early indication by understanding the symptoms of a deficiency. Muscle aches or spasms, mental tension, anxiety, headaches, brain fog, difficulty sleeping and suboptimal cardiovascular health are some of the most common signs your cells aren’t getting enough magnesium.*

The Unique Benefits of Magnesium Glycinate
Made with 300 mg of highly absorbable magnesium glycinate, Durable MAGNESIUM delivers magnesium to your cells in a form they can use—without the laxative effect other magnesium supplements are known for.*

Magnesium glycinate is chelated, meaning that the mineral is molecularly bound to the amino acid glycine, which makes it significantly more absorbable—and more effective.*

Glycine also provides some unique benefits. It helps maintain neurotransmitter balance in your brain and supports a healthy, relaxed nervous system. This makes magnesium glycinate the magnesium form of choice for reducing anxiety and promoting a calm, yet energized mental state. Taken before bed, magnesium glycinate will help you enjoy a more restful sleep.*

Concerned About Heart Health? Then Magnesium Is a Must!
Durable MAGNESIUM also provides powerful support for a healthy cardiovascular system. Magnesium helps relax the smooth muscles within blood vessels, which encourages healthy arterial function and normal blood pressure.*

Fast Acting and Truly Effective Results
Delivering a research-backed dose of the most effective, absorbable form of magnesium makes Durable MAGNESIUM the best product of its kind on the market. Whether you are taking it to support a healthy brain and nervous system, a strong cardiovascular system or to promote relaxation and better sleep, you are guaranteed fast-acting and truly effective results.*

Infuse Your Cells With Highly Absorbable Magnesium

Magnesium Glycinate

An essential mineral, magnesium is needed for over 300 biochemical reactions in the body. The glycinate form is gentle on the digestive system and readily absorbed into the bloodstream.*

Chelated for Maximum Bioavailability

The magnesium in magnesium glycinate is chelated, or bound, to the amino acid glycine, which makes it significantly easier for the body to absorb. Glycine also supports brain and nervous system health.*

Frequently Asked Questions

Dr. Kevin Passero Answers

Functional medicine expert, licensed naturopathic physician
and Durable co-founder Dr. Kevin Passero answers your top questions.

What’s the difference between the glycinate, citrate and other forms of magnesium?


Magnesium comes in various forms typically attached to another molecule in a structure called a chelate. Differing chelates of magnesium lend themselves to different therapeutic actions due to changes in absorbability and based on the biological properties of the attached molecule.*

Magnesium glycinate is a chelate structure where magnesium is attached to the amino acid glycine. It and magnesium citrate are considered the most highly absorbable forms of magnesium. However, unlike magnesium citrate, magnesium glycinate does not produce a laxative effect in the large intestine, making it gentler and often more tolerable than magnesium citrate.*

Magnesium glycinate has other unique and beneficial effects due to the action of the amino acid glycine. This amino acid plays an important role in the neurotransmitter balance in your brain and supports the health of the nervous system.*

How long will it take to feel the effects?


Like most nutritional supplements, Durable MAGNESIUM will take time and consistent use to build up in your system in order to achieve maximum effectiveness. However, depending on your current magnesium levels, you can expect to feel some benefits more quickly—often beginning the first time you take it. You might notice that you feel calmer and less stressed or tense. Take Durable MAGNESIUM before bed for better, more restful sleep.*

What causes magnesium deficiency?


Due to modern farming practices and soil depletion, magnesium levels in our food supplies have fallen dramatically over the last 50 or so years. As a result, most of us aren’t getting the magnesium we need from our diets—even if we make an effort to include healthy, magnesium-rich foods—which makes supplementation a must.*

Stress can also contribute to magnesium deficiency. When we’re under stress, the body moves magnesium out of the cells for protection and regulation.*

Are there any side effects?


There are no significant known side effects associated with taking magnesium glycinate. Notably, unlike other forms of magnesium, it will not cause digestive distress or have a laxative effect. However, pregnant or nursing women should always consult with their healthcare provider prior to using any supplements. Additionally, if you a have any medical conditions or are taking any type of medication, it’s best to check with your healthcare provider before taking any supplements.*

What is the Nuflow Complex that is listed in your Other Ingredients?


Nuflow is a natural flowing agent. Flowing agents are used in the production of all encapsulated or tableted supplements to help prevent the ingredients from clumping as they flow through the encapsulating machinery. Most companies use synthetic flowing agents like silicon dioxide, magnesium stearate, talc or steric acid, which can potentially inhibit the absorption of the active ingredients or may be potentially harmful.*

Nuflow is a revolutionary flowing agent naturally derived from the outer hulls of rice which, has a high concentration of naturally occurring silica. This works very effectively to help the ingredients flow smoothly and evenly through the machinery. It represents a breakthrough in the world of nutritional supplements, being the first completely natural flowing agent derived from food.*
