14. How Magnesium Deficiency Impacts Health
Magnesium is essential for various bodily functions, and a deficiency can lead to several health issues. It’s estimated that about 60% of adults in the United States don’t consume enough magnesium. Chronic magnesium deficiency can manifest in several symptoms.
- Fatigue
- Muscle cramping, spasms, or weakness
- Convulsions
- Abnormal eye movements (nystagmus)
Certain medical conditions and medications can reduce magnesium absorption, making it harder for the body to maintain adequate levels of the mineral. These include:
- Age (older adults)
- Gastrointestinal diseases, like Crohn’s and celiac disease
- Diabetes
- Alcohol dependence
- Hypertension (high blood pressure)
- Diuretic medications (water pills)
- Proton pump inhibitors (PPI) drugs to reduce stomach acid
Magnesium deficiency may also increase the risk of developing certain conditions. Adequate magnesium intake may offer health benefits and protect against medical conditions, including:
- High blood pressure
- Heart attack
- Stroke
- Type 2 diabetes
- Osteoporosis
- Migraine headaches
- Cancer
- Asthma (in children)
15. Too Much Magnesium: What You Need to Know
While magnesium deficiency is more common, consuming too much magnesium is rare and typically occurs with health conditions like kidney failure. It’s always best to consult with a healthcare provider before making significant changes to your diet or starting any new supplements.
16. Should You Consider Magnesium Supplements?
The best way to obtain magnesium varies depending on factors such as age, diet, and overall health. While most people can get enough magnesium through their diet, some may require a supplement to boost their nutrient levels.
Here are the U.S. Recommended Dietary Allowances for magnesium:
| Age | Male | Female | Pregnancy |
|---|---|---|---|
| 19-30 | 400 mg | 310 mg | 350 mg |
| 31-50 | 420 mg | 320 mg | 360 mg |
| 51 and older | 420 mg | 320 mg | N/A |
If you’re considering supplementation, it’s important to know that different forms of magnesium supplements exist. Common supplements to increase magnesium include magnesium citrate, magnesium oxide, and magnesium chloride.
Magnesium’s forms and uses include:
- Magnesium oxide: Used to help treat magnesium deficiency or issues like constipation.
- Magnesium citrate: A laxative that can help with occasional constipation.
- Magnesium chloride: Used to help boost magnesium levels and may be beneficial for other conditions like prediabetes.
The tolerable upper intake levels for magnesium from supplements vary by age but are the same for males, females, and pregnant people.
| Age | Tolerable Upper Intake Level |
|---|---|
| 1-3 years | 65 mg |
| 4-8 years | 110 mg |
| 9-18 years | 350 mg |
| Adults 19 and over | 350 mg |
Side effects of higher magnesium levels with supplement use can include digestive problems like diarrhea, and dizziness or fainting if your blood pressure drops. Toxicity at high doses (more than 5,000 mg a day) can also lead to heart arrhythmias, nausea, and dizziness.
17. Optimizing Magnesium Absorption
To improve your body’s ability to absorb magnesium, experts may recommend the following:
- Avoiding taking a zinc supplement at the same time as magnesium, as zinc may interfere with magnesium absorption.
- Choosing supplements containing magnesium citrate, magnesium lactate, or magnesium aspartate, as these forms are better absorbed in the small intestine.
- Choosing a time-release magnesium supplement, as it improves absorption.
