"But what is it, and how does it work? What causes muscle and leg cramps to begin with?"
📚(*Learn the facts below: watch the video, then read about the two main causes of cramps, how the product works, what results to expect, and an FAQ at the end. 5–10 minute read.)
2 Minute Video, Explains Everything
There are Two Hidden Causes of Severe Cramps, and the #1 Most Common is a Deficiency of the Vital Mineral, Magnesium. (People Age 60+ are Especially Vulnerable to Low Magnesium, Even if Their Blood Tests Are "Normal"!) But Don't Bother with Standard Cheap Magnesium Supplements — They Don't Absorb and Have Laxative Side-Effects (& are Often Jammed With Fillers / Made Overseas with No Transparency.)
According to medical experts at the famous Mayo Clinic, the #1 major cause of muscle cramps everywhere in the body is a serious magnesium deficiency. (this includes leg and foot cramps, both day and night.) (References 1-3).
It's very common: 78% of Americans have a severe lack of magnesium (4). This is a big red flag -- because magnesium is a necessary nutrient vital for all aspects of health. Your body needs magnesium to make your muscles relax -- as well as to decrease pain, swelling, and inflammation throughout the body (6-7). Studies show that by fixing a magnesium deficiency, it is possible to end leg cramps and stop them from ever coming back (5, 8-12).
But most people don't eat enough magnesium-containing foods (like fruit and green vegetables, nuts and seeds, dark chocolate, magnesium-rich mineral water). And they LOSE too much magnesium from stress, aging, caffeine and alcohol, soda, sweating, and certain medications. (As we get older, we are unable to absorb and retain magnesium like we could when we were younger, due to weaker digestion.)
Unfortunately, most magnesium supplements are low quality and the wrong formulation for cramps -- so they don't help much. They are also hard to absorb and cause digestive upset -- especially in older people. (And, many manufacturers make their magnesium overseas as cheaply as they can, without adequate transparency.)(All Scientific References)
The blood test that you received is called a SERUM test, which is part of any normal blood chemistry panel. Unfortunately, this blood test does not accurately portray your body's supplies of magnesium. Here's why: in order for your heart to beat, your body has to maintain a steady amount of magnesium in your blood at all times. It does this by pulling magnesium from your bones and tissues as needed -- including your muscles. So, you can have a perfectly normal serum test and still be low in magnesium in your muscles -- causing your cramps. The gold standard test for true magnesium levels is called an RBC magnesium test, NOT serum. This test is a special request, it is not normally administered by most doctors.

The #2 Cause of Cramps: Excess Calcium — and Magnesium Balances It.
We love calcium in America. Milk, cheese, yogurt - and calcium supplements - they are all supposed to be good for us, right?
It's not always true. Excess calcium is a bad thing, it is called calcification, and is a process associated with aging. Your joints, organs, and muscles collect excess calcium, making them stiff and rigid.
Americans ingest more calcium than any group in the world -- on top of that, we are told to take Vitamin D, which accelerates calcium absorption. But excess calcium is a major cause of muscle cramps.
Calcium tells muscles to contract, and magnesium tells them to relax. They are "antagonists" of one another, meaning they can block each other's activity. This means that muscle cramps are a story of magnesium-calcium imbalance. So -- to help stop muscle cramps, we recommend:
1) Decreasing calcium ingestion, especially at night
2) Decreasing Vitamin D temporarily (it's very important for health, but there is also too much of a good thing) Never take vitamin D at night either!
3)Taking high-absorbing magnesium daily to balance the calcium.
Now you understand the two main causes — and both require more magnesium! Cramp Defense® is proven to restore your levels fast and long-term, fixing your cramps for good. (Why does it work so well when “regular” magnesiums fail? The answer: it absorbs the best, even for people with weak or sensitive digestion.) Why does it absorb so much better?
✅ We Based the Formula on Fruit & Vegetables: The chemical structure of our magnesium (fully-reacted, triple-milled magnesium malate trihydrate complex, aka Truemag® - only found in Cramp Defense®) copies what's found in healthy plants, meaning our bodies recognize it, allowing it to absorb easily. (Other magnesium types, like magnesium oxide, are made from crushed rocks and many people's bodies reject it.)
✅ We Made it Pure, with No Extras: We make our product 100% free of impurities, with our patented process -- and, we use no binders, coatings or fillers that slow down absorption and cause irritation. (We 100% manufacture in the USA and lab-test in an FDA-inspected facility; many other companies manufacture overseas, with no transparency.)
✅ We Made it Without Side-Effects: Due to it's high purity and unique formula, it causes no stomach upset/laxative effects. No running to the toilet. Other magnesiums such as magnesium citrate and chloride are literally used as laxatives before colonoscopies. If it's in the toilet, its not being absorbed. This is key for long-term cramp prevention!
✅ We Used Capsules not Tablets: Capsules dissolve and absorb much better and faster than tablets, especially for people with slow or weak digestion.
✅ End Result = Long-Term Cramp Relief: Due to all these factors, it starts working immediately and becomes more effective with time as your reserves of magnesium are restored.
Results, What to Expect
Based on our 15 years of customer data:
🟢 80% of people get total relief - no more cramps, as long as they keep taking their daily dose.
🟡 10% of people get partial relief - their cramps are lower in severity and less frequent.
🚫 10% of people get no results - their cramps are caused by something else, or they have other complicating factors. That's why we have a 100% risk free return policy.
How to Get Started: (In Consultation with Your Doctor)
1. Start small: Take 1 capsule daily with food for optimal absorption.
2. Take more ONLY if needed: Increase gradually and split between morning and night.
3. Most users feel great with just 1–2 capsules daily.
4. Give it a chance to build up: Starts working immediately, but keep taking for at least 2 weeks before you make up your mind.
5. Stay consistent: Your body loses magnesium daily, so you need to replace it to keep cramps away.

Frequently Asked Questions
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 to produce. Unfortunately 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".
- 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 it tends to be expensive and only found in large, difficult to swallow tablets.
- Magnesium chelate or glutamate:This product is low quality, because it has large amounts of "unbound magnesium" in the form of oxides. This poor form of magnesium causes laxative effects.
- Magnesium chloride: This turns to liquid when exposed to air, making it difficult to deliver via capsule. It is not naturally found in food.
- 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 a purified organic form called Truemag®, found in fruits and vegetables, not some crushed up rock.

In our experience, most people get significant results from our product. Some people have become totally free of leg 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 muscle cramps every night. Everyone is different. However, some people do not see results, 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 Money Back Guarantee -- to give you plenty of time to see if it works for you .
Although everyone responds differently, many people see results with their first dose. But we recommend trying it for 2 weeks to give it a full chance of working.

Many doctors know that magnesium is important, but they don't realize how important. Even then, they rarely know which magnesium forms actually work. Many doctors believe that magnesium is just another medication which decreases muscle cramps. In reality, lack of magnesium is the hidden reason WHY most people get muscle cramps.

Our magnesium is designed to maximize results, not milligrams. It simply absorbs better than other products, so you need less of it. A lower dose per capsule also makes it easier to "dial in" the exact dose you need to get results.

Take the smallest dose that works for you. It absorbs best when you take it with food. Experiment to see what dose works best for you. Below is the size of the capsule compared to a dime. You can also open up the capsules and mix the powder with a food like applesauce or yogurt -- the powder has no flavor.
