We are MgBRIGHT LLC, and our only product is Cramp Defense™. We were founded in January 2011, and after a period of research and development, began selling the product in February 2012. Our team is based in Houston, TX and the product ships from a warehouse in Dallas, TX. The company is a member of the Better Business Bureau. If you ever need to reach us, please email us at support@crampdefense.com . For more information about the company, visit About Us.

The product is safe as long as it doesn't interact with your medications. Talk to your doctor or pharmacist. The product works for over 80% of people, but every person is different, so we cannot predict whether it will work for you. That's why we have the 100% guarantee for 120 days -- so you have plenty of time to try it.

In our experience, about 80% of people get substantial results from Cramp Defense®. By fixing their magnesium deficiency, some have become totally free of their muscle cramps; others have seen a significant decrease in the pain and/or frequency of their symptoms. This could mean that the pain is cut in half, or they only get cramps once a week instead of every night. Everyone is different. About 20% of people do not see results from Cramp Defense™, even after increasing their dose and taking it for more than a month. This usually means that magnesium deficiency is not causing their problems. This is why we offer the 100% Guarantee -- to give you plenty of time to see if it works for you. 

Most people see results immediately. But we recommend trying it for 2 weeks to give it a full chance of working.

The smallest dose necessary to get relief. Experiment with the dose to see what works best for you. Take it with food for best absorption.  

70mg of magnesium is all that is possible for a small capsule. 

Let us explain. There is 583mg of magnesium malate in a capsule. 12% of that is elemental magnesium (70mg), the rest is malate (513mg).

There are no magnesium supplements that are 100% magnesium, since pure magnesium does not exist in nature -- it is always bound to another molecule.  

Although Cramp Defense™ is only magnesium and malate, natural parts of a healthy diet, please talk to your doctor before starting any new dietary supplement. Certain conditions and medications can affect how the body processes and excretes magnesium.

We are not allowed to give medical advice. Talk to your doctor or pharmacist!

Magnesium stearate helps in the encapsulation process of our product. There is no evidence that it is harmful. Please read the following articles for more information;

Some people have reported improvement upon taking our product.

Other products are manufactured all over the world by the lowest bidder. Cramp Defense™ is made in the USA, in a multi-million dollar, 80,000 square foot facility. This facility is inspected by the FDA. Furthermore, our facility has voluntarily adopted a standard even higher than FDA inspection requirements, which requires the strictest levels of purity, precision and sanitation.

We do not provide Vegan/halal/kosher capsules. The only capsule we provide is made with gelatin.

However, our product is just as effective diluted in water or taken with yogurt. The capsule is easily openable.

QUESTIONS REGARDING YOUR MEDICATION, DRUG INTERACTIONS, OR MEDICAL CONDITIONS WILL NOT BE ANSWERED. WE ARE NOT PERMITTED TO GIVE MEDICAL ADVICE. TALK TO YOUR PHARMACIST OR DOCTOR.

The blood test that your doctor performed is called a SERUM magnesium test, which is part of any normal blood chemistry panel. Unfortunately, this test is not an accurate indicator of your body's storage of magnesium. Here's why: in order for your heart to beat (and for you to be alive) your body has to maintain a steady amount of magnesium in your blood at all times. It accomplishes this by pulling magnesium from your bones and tissues as needed -- including your muscles. So you can have a perfectly normal magnesium blood test and be LOW in magnesium in your muscles -- causing your cramps.

Many doctors know that magnesium is important for muscle cramps, but they don't realize how important, and they don't know which magnesium forms actually work. Many believe that magnesium is just another medication, able to help you control your symptoms. In reality, lack of magnesium is the hidden reason why most people get muscle cramps.

There are a variety of forms and each has pros and cons:

• Magnesium oxide and hydroxide: Supplement companies love this stuff because it is cheap as dirt. Unfortunately dirt is more effective. It is very poorly absorbed (only 8%), and is highly laxative. But nonetheless, it is what you find in most common multi-vitamins. It also happens to be the active ingredient in Milk of Magnesia. 
• Magnesium citrate: It is well absorbed, but is also highly laxative. It is the main ingredient in those glass bottles of laxative at the drug store.  If you have ever had a colonoscopy, this is what they gave you to "clean you out". It is the main ingredient in those canisters of fizzy magnesium powder found in vitamin stores.  
• Magnesium sulfate: Also known as Epsom Salt.  It is also very laxative -- that's partly what they sell it for.  But it is great for soaking! 
• Magnesium glycinate: This is magnesium bound to the amino acid glycine. This form is not ideal, because... well, this gets a bit technical: Glycine acts as a "co-agonist of the NMDA receptor" where magnesium is an antagonist. What does that mean? Basically, magnesium tells your neurons to slow down, and glycine tells them to speed up.  So to a certain extent, magnesium and glycine cancel each other out. Mixing these two ingredients does not make sense, especially if relaxation is a goal of yours.  
• Magnesium chelate or glutamate: Both are the same thing. Glutamate, like glycine, is also "NMDA agonist", with all the same problems. Plus, these products are super-cheap, in part because they frequently have substantial amounts of "unbound magnesium", i.e. the problematic magnesium oxide, as a byproduct of its manufacturing process. 
• Magnesium chloride: Also known as road de-icer.  In supplement form, is very well absorbed, non-laxative, and free of all other side effects -- but it turns to liquid when exposed to air, making it prohibitive to deliver via capsule or tablet.  It is extremely bitter, so makes a lousy drink, too.  
• Magnesium taurinate:  This is magnesium bound to the amino acid Taurine. It has the side effect of causing extreme drowsiness, which makes it difficult to take during the day. It is also very expensive.  
• Cramp Defense™: High absorbing, non laxative, no weird side effects. It's an organic form found in fruits and vegetables, not some crushed up rock.

Although magnesium deficiency is a very common cause of cramps, there are other causes too. Please see this list:
