3 Types of Magnesium, One Powerful Formula*
Unlike most magnesium supplements that rely on a single form, MagTech® combines three highly bioavailable types: each chosen to support a specific area of health.*
Magnesium L-Threonate (Magtein)
This clinically-tested form of magnesium is shown to cross the blood-brain barrier to support brain health.* Studied for its role in cognitive function and memory support, it also helps improve REM sleep and relaxation.*
Magnesium Glycinate
We include magnesium glycinate because it helps support brain health, relaxation, and cognitive function.*
Magnesium Taurate
This form of magnesium is combined with taurate, an amino acid that’s involved in hundreds of chemical reactions within the brain and body.* Magnesium even contributes to improved sleep quality and helps sustain natural sleep rhythms.*
Together, these forms create a comprehensive MagTech® formula designed to support your sleep, relaxation, and brain health: all in one effective capsule.*

Frequently Asked Questions
What makes MagTech better than other magnesium supplements?
MagTech™ is a magnesium complex that combines the 3 most bioavailable forms of magnesium in their science-proven doses to provide you the most potent benefits from this super mineral. It enhances brain function, aids relaxation and improves sleep quality.
What is MagTech made out of?
Magtech™ contains the most bioavailable forms of magnesium: Magtein Magnesium L-Threonate, Magnesium Taurate, and Magnesium Glycinate. Magtech improves brain function, aids relaxation, decreases anxiety, and sleep quality.
When should I take my MagTech?
Take up to 2 servings a day, preferably 3 capsules in the afternoon and 3 capsules in the evening, or as directed by your healthcare provider. This will help you have a deeper REM sleep, and your muscles will be able relax during sleep. Warning: If you are pregnant, nursing, or taking medications, consult a healthcare practitioner before use.
What does elemental vs actual Magnesium mean?
The supplement facts panels of dietary supplements state the amount of elemental magnesium in the product, not the weight of the entire magnesium compound. There are many different types of magnesium compounds. Each compound provides a different amount of elemental magnesium and varies in bio-availability (ability to be absorbed by the body). Bio-availability is most important thing to consider when evaluating the effectiveness of a dietary supplement. For example, Magnesium Oxide is the most dense magnesium compound available. It contains 300 mg of elemental magnesium per 500 mg of material, but it's bio-availability is extremely poor. Studies have shown that only about 4% of its elemental magnesium is actually absorbed by the body. Natural Stacks MagTech contains the three magnesium compounds that are known to have the highest absorbtion; Magnesium L-Threonate, Magnesium Taurate, and Magnesium Glycinate. These compounds are not as dense as other forms of magnesium(less elemental magnesium by weight) but they are significantly more bio-available.
What natural stacks work well with MagTech?
You can add GABA Brain Food and SLEEPBIOTIC for ultimate relaxation and sleep support.
Can Magnesium supplements help with deficiency?
Yes. Magnesium deficiency is the second most common nutrient deficiency in developed countries. Obtaining adequate magnesium through diet alone has become difficult due in part to our highly processed, modern diets and mineral depletion in soil. Supplementation is a safe, reliable, and effective means to improve magnesium levels and overcome deficiency.
What is Magnesium L-Threonate?
Magnesium L-Threonate is a unique form of magnesium known to boost cognitive abilities including learning, memory, and brain aging. Natural Stacks MagTech uses MagTein, a chelated magnesium l-threonate developed by neuroscientists at MIT.
Are there any side effects using a Magnesium supplement?
Side effects are uncommon when supplementing magnesium at the standard dosage level. In some people, exceeding doses of 350mg might cause stomach upset, nausea, vomiting, or diarrhea. If you are experiencing those side effects, consider taking a lesser amount.
How long does it take for Magnesium to work?
The sooner you take action to improve your magnesium levels, the sooner you'll start experiencing the mineral's benefits. In the near term, a fully bioavailable magnesium works almost immediately after ingesting your first dose. The effects compound over time with continued magnesium use, contributing to greater overall health and wellness. Since most people are deficient in magnesium it may take up to a few weeks of consistent use before you notice the benefit of magnesium supplementation.
What does chelated magnesium mean?
Chelation occurs when an amino acid “grabs” and holds onto a mineral molecule, (magnesium glycinate for example glycine is the amino acid) usually making a ring formation that doesn’t break down in the digestive process.This is why chelated minerals are more bioavailable - by “surviving digestion” the minerals can get carried to your cells bound to the amino acid. Any mineral (magnesium, zinc, etc) should always be taken in a chelated form for increased absorption and bioavailability rates. These superior chelated minerals are rare, expensive, and take a long time to produce. In fact, there are only few mineral suppliers in the world that actually make 100% reacted magnesium chelates. Most magnesium supplements on the market that claim to contain chelated magnesium actually do not and are mis-labeled. The problem starts with the ingredient suppliers. Many suppliers claim to make chelated magnesium (like magnesium glycinate) because it's a superior form and it allows them to charge a higher price. However the magnesium they sell is actually only partially chelated and is blended with an unknown percentage of unbound inorganic magnesium (like magnesium oxide). The result is an unbound inorganic magnesium that is very poorly absorbed, thus causing the bowel intolerance symptoms caused by most magnesium supplements. Albion Laboratories has been selling magnesium glycinate chelate to supplement companies that is NOT fully chelated, containing undisclosed amounts of magnesium oxide. Affected supplement brands include Bluebonnet Nutrition, Vitacost, and Nature’s Lab. So far there have been two class-action suits brought against them. It's no surprise that Labdoor's magnesium rankings have some of the most respected magnesium products like Natural Calm scoring the worst --> https://labdoor.com/rankings/magnesium At Natural Stacks we're changing the industry with our open-source full-label disclosure policy and meticulous ingredient sourcing.
