Most of the magnesium in your body is inside your bones and cells. Only 0.3% of your magnesium is in your blood serum. One of the biggest mistakes people make when assessing magnesium deficiency is relying on blood magnesium levels.
Over 300 medications can deplete your magnesium levels. Other factors that can cause magnesium deficiency include the following:
• Stress
• Sugar
• Caffeine
• Alcohol
• High insulin
• Low stomach acid
• Low salt
• Low vitamin D
Here are 9 of the most common magnesium deficiency symptoms:
1. Anxiety/panic attacks
2. Waking up at 2 AM
3. Eye twitching (tetany)
4. Heart pounding after eating
5. Exhausted from thinking
6. Random chest tightness
7. Sugar or carb cravings
8. Wired but tired
9. Feeling heavy
Restless legs syndrome can also result from a magnesium deficiency.
Magnesium oxide is one of the most common forms of magnesium available, but also the worst! It has a 3% absorption rate and can cause diarrhea at higher doses.
Magnesium glycinate combines magnesium with glycine, a protein that supports GABA in the brain, and has an absorption rate of 80%. The best time to take magnesium is late in the day. When taking more than 400 mg of magnesium, spread your doses throughout the day.
To avoid magnesium deficiency, follow a low-carb diet, increase your stomach acid, and ensure you’re getting enough vitamin D.

| 0:00.0 | A lot of people think they're tired, inflamed, and stressed for no reason, when in reality |
| 0:06.0 | they have one huge mineral deficiency, and that is magnesium. Today we're going to discuss |
| 0:11.6 | the nine hidden magnesium deficiency symptoms that most doctors don't even realize. Most of the |
| 0:17.7 | storage of magnesium is inside your bones, as well as inside your cells. |
| 0:23.6 | Only 1 third to 1%, that's 0.3% of your magnesium is in your blood serum. |
| 0:32.6 | And so the worst mistake that people make, especially doctors, when they're evaluating |
| 0:36.6 | magnesium, is to depend on this blood level of magnesium. That is a big mistake. Let's say you want to |
| 0:42.9 | determine someone's wealth by having them show you what they have in their wallet as far as their |
| 0:48.2 | coins. That is not a good place to determine their wealth. You want to look actually in their |
| 0:52.1 | bank account. You don't want to look in their pocket. Well, that's the exact mistake that a lot of people make when they're looking |
| 0:58.1 | into the blood for not just magnesium, but other nutrients as well. There's over 300 medications |
| 1:04.1 | that can deplete your magnesium. Let me also just show you all the other things that can deplete |

| 1:19.1 | population has insulin resistance. So they can't even absorb the normal amounts of magnesium. |
| 1:24.8 | Low hydrochloric acid in your stomach, chances are you don't have enough |
| 1:28.4 | hydrochloric acid. We've already covered the medication, low salt, and low vitamin D can all lower |
| 1:35.3 | your magnesium levels. Now let's go through the hidden magnesium deficiency symptoms. Number one, |
| 1:41.1 | anxiety. I'm talking about a sudden anxiety that comes out of nowhere. |
| 1:45.0 | There's no real reason to have anxiety and all of a sudden you feel anxious. |
| 1:49.0 | It could also be a panic attack as well. |
| 1:51.0 | You want to think about magnesium as your brakes, okay? |
