    Not so sure about this product, my normal mag glycinate seems to work as well, without causing some awful leg cramps at night. I understand this contrary to your intention, but I haven’t changed anything else in my routine.

    These capsules are very toxic for me. They caused a very rapid heartbeat, shortness of breath and I was up all night after taking one. My doctor convinced me to take one a week later trying to reassure me that my experience was not from these capsules. The same thing happened the second time. These are definitely not for me.

    Since taking MagnesiumER I’ve been sleeping full 7-8 hrs a night (which hasn’t happened in >5 yrs). I’ve tried several other forms of magnesium and haven’t had the overall feeling of well-being like with magnesiumER. Recommended dose is 2 capsules twice a day & sometimes I forget to take one but I still sleep soundly all night.

    It does help me sleep! I also take the ionic magnesium liquid product from Mother Earth. I take 4 Mag ER in evening and two droppers of the liquid ionic magnesium before bed. If I wake up at 3, I take 2 more droppers of the liquid and I can get back to sleep! The liquid works very quickly. Also, no leg cramps at night!

    I was surprised how well these magnesium capsules work for me. The effect is subtle and perhaps it is the combination of many types of magnesium and the slow release. Thank you for offering me an opportunity to try… thumps up!

In addition to better sleep, muscle building, recovery, brain health, migraines, the immune system, heart health, blood pressure regulation and even weight loss & metabolic health.1

But when you don’t get enough or the right types of magnesium, it can wreak havoc in just about every aspect of your health.

  • Time-released delivery of 7 forms of essential magnesium
  • Highly absorbable yet gentle on digestion
  • Promotes restful sleep, calming & reduces stress
  • Supports performance & energy
  • Aids in metabolism, weight management, muscle repair & recovery

Improve Sleep & Lower Stress With Nature’s Most Powerful Magnesium


Magnesium supports hundreds of different biochemical reactions in the body including sleep, energy production, metabolism, heart health and more.1 Magnesium recharges the body’s muscles and internal battery, but up to 80% of Americans are deficient in this nutrient.2,12,13

When the body lacks the full spectrum of magnesium it needs, the entire internal system slows to a trickle. Biochemical reactions that normally take milliseconds might take hours or days. You can experience poor sleep, anxiety, stress, panic attacks and total body exhaustion. Every potential health problem is far more dangerous, and the body begins a downward spiral that can feel impossible to recover from.

Magnesium ER is your all-in-one, complete solution! With 7 forms of essential magnesium, Magnesium ER is a full spectrum, extended release formula, so you can feel the benefits all day. It also contains fulvic acid for absorption support and faster results, without digestive upset.

Magnesium ER is the most potent, complete, natural, full-spectrum magnesium in extended-release form ever created.

Most magnesium supplements only offer one or two types of magnesium, but your body needs all seven to truly transform your health. 

Our complete formula includes all 7 types of magnesium that your body needs, and is highly absorbable and remarkably gentle.

Magnesium Glycinate – Supports long-lasting calm and relaxation. This form of magnesium promotes mental and emotional calm and enhances the quality of sleep. 3

Magnesium Malate – Nourishes and recharges the body’s muscles and internal battery and supports blood sugar control. 4

Magnesium Taurate – Supports your heart and blood sugar regulation and reduces anxiety and stress.5

Magnesium Orotate – While also helpful for the heart, this form of magnesium is best for metabolism, recovery and energy. 6

Ionic Magnesium – As the fastest absorbing form of all, you’ll feel immediate effects. It is effective for leg cramps, low magnesium levels and heartburn.7

Magnesium Citrate – One of the most bioavailable forms of magnesium. Helps with constipation and digestion.8

Magnesium Sucrosomial – This is a form of magnesium whereby the molecule is delivered via a liposomal-like structure made up of Sucrosome®. Sucrosome® acts as a protector, increasing absorption and bioavailability.9

Magnesium ER also includes vital cofactors, such as:

VitaShine Vitamin D3 (Vegan-friendly) – Magnesium and Vitamin D go hand in hand. Magnesium intake is essential for vitamin D production as it regulates key enzymes that convert vitamin D into an active form.

Vitamin B6 – Aids in delivering magnesium directly to cells, supporting absorption at the intracellular level. Helps relieve muscle cramps, insomnia, anxiety, heart palpitations, and speeds muscle recovery. 

Fulvic Acid and Zinc – These act as cellular absorption boosters, making all of the ingredients work better by enhancing bioavailability and utilization of every ingredient in Magnesium ER.

Take 4 capsules with water daily.

We suggest taking 2 capsules of Magnesium ER in the morning for all-day energy production, lasting calm, and stress support throughout the day, and 2 capsules in the evening to transition into a restful night of sleep.
