Why do we need magnesium?

Magnesium is responsible for over 300 biochemical reactions in the body and impacts blood pressure, metabolism, immune function and many other aspects of health. Some experts claim that magnesium deficiency is the single largest health problem in our world today. There are many reasons that deficiency is so widespread in modern times (even though it wasn’t in the past). Depleted soil conditions mean that plants (and meat from animals that feed on these plants) are lower in magnesium. Use of chemicals like fluoride and chlorine in the water supply make magnesium less available in water since these chemicals can bind to magnesium. Common substances that many of us consume daily, like caffeine and sugar, also deplete the body’s magnesium levels. So does stress. In other words, the lucky (but small) percentage of the population that lives near the ocean (a good source of magnesium) and eats foods grown in magnesium rich soil, drinks magnesium rich water, and doesn’t suffer from stress or consume sugar or caffeine might be ok… but the rest of us might need some additional magnesium.

Magnesium Deficiency Leads To:

1. Calcification of the Arteries – Though this is not (hopefully) the first symptom of magnesium deficiency, it can be one of the most dangerous. Calcification of arteries from low magnesium levels can lead to coronary problems like heart attack and heart disease. In fact, half of all heart attack patients receive injections of magnesium chloride to help stop the blood clotting and calcification.
2. Muscle Spasms and Cramps – Just as calcification causes stiffening of the arteries, it can cause stiffening of muscle tissue as well, leading to cramps and spasms. I had horrible leg cramps during one of my pregnancies. Potassium didn’t help at all, but magnesium fixed the problem almost instantly (which makes sense in light of the sodium:potassium pump).
3. Anxiety & Depression – There is a lot of research showing that magnesium deficiency can have a tremendous impact on mental health. Psychology Today explains one possible reason: Magnesium hangs out in the synapse between two neurons along with calcium and glutamate. If you recall, calcium and glutamate are excitatory, and in excess, toxic (link is external). They activate the NMDA receptor. Magnesium can sit on the NMDA receptor without activating it, like a guard at the gate. Therefore, if we are deficient in magnesium, there’s no guard. Calcium and glutamate can activate the receptor like there is no tomorrow. In the long term, this damages the neurons, eventually leading to cell death. In the brain, that is not an easy situation to reverse or remedy.
4. High Blood Pressure/Hypertension – This is perhaps one of the most well-studied areas of magnesium deficiency. A Harvard study of over 70,000 people found that those with the highest magnesium intake had the healthiest blood pressure numbers. A follow up meta-analysis of available studies showed a dose-dependent reduction of blood pressure with magnesium supplementation. A University of Minnesota study showed that the risk for hypertension was 70% lower in women with adequate/high magnesium levels.
5. Hormone Problems – I personally saw the effects of low magnesium in my hormone levels. The higher the estrogen or progesterone levels in a woman’s body, the lower the magnesium (pregnancy anyone?) This is also part of the reason why pregnant women experience more leg cramps and women notice more of these muscular type complaints and PMS in the second half of their cycles when progesterone/estrogen are higher and magnesium is depleted. Chocolate is a decent source of magnesium, and there is speculation that cravings for chocolate may be a sign of magnesium deficiency. Muscle cramps related to the menstrual cycle can also be related to magnesium levels. Dr. Carolyn Dean, author of the Magnesium Miracle, often recommends that women with bad PMS and cramps take magnesium early in their cycles before the symptoms begin.
6. Pregnancy Complaints – Related to the hormone problems above, magnesium levels can drastically affect pregnancy health and mood. I noticed this when my morning sickness was tremendously less in my pregnancy when I supplemented with transdermal magnesium. Magnesium is also often used to help with pregnancy related hypertension and muscle cramps, to help ward off preterm labor and to alleviate headaches.
7. Sleep Problems – With all of the above symptoms of deficiency, it makes sense that magnesium would have a drastic impact on sleep, but the impact is often immediately noticeable when a person starts taking magnesium. Dr. Mark Hyman calls it the ultimate relaxation mineral. Magnesium helps relax the body and the mind, which both contribute to restful sleep. Additionally, magnesium is needed for proper function of the GABA receptors in the brain, and GABA is the neurotransmitter that allows the brain to transition to a restful state.
8. Low Energy – Magnesium is required in the reactions that create ATP energy in the cells. Let’s flash back to freshman biology for a minute. ATP or adenosine triphosphate, is the main source of energy in the cells and it must bind to a magnesium ion in order to be active. In other words, without magnesium, you literally won’t have energy on a cellular level. This shows up as fatigue, low-energy, lack of drive and other problems.
9. Bone Health – Calcium is always considered the most important mineral for bone health, but it turns out that magnesium is just as important (or even more so!) In cases of magnesium deficiency, the bones suffer in multiple ways:
10. Vitamin D Absorption: Magnesium is needed for Vitamin D to turn on calcium absorption- this is why it is also important to get enough magnesium when taking Vitamin D (or magnesium levels can become even more depleted)
11. Proper Calcium Use: Magnesium is needed to stimulate the hormone calcitonin which draws calcium out of the muscles and soft tissues and into the bones. This helps explain why magnesium helps lower the risk of heart attack, osteoporosis, arthritis and kidney stones.
12. Other Mineral Deficiencies – Many vitamins and minerals work synergistically, and magnesium is a work horse on this list. It is needed for proper utilization of calcium, potassium, Vitamin K, Vitamin D and many other nutrients. By using magnesium externally, or transdermally (meaning “across the skin”) the body can absorb what is needed without absorbing to much. It is similar to soaking in an Epsom salt bath or in the ocean.

Where can we find magnesium?

Magnesium is widely distributed across nature, the human body, and the earth.

• Dietary Sources: Magnesium is naturally concentrated in plant and animal foods. The best sources include leafy green vegetables (like spinach), nuts (almonds, cashews), seeds (pumpkin, chia), whole grains, legumes (black beans, soybeans), and fish. You can explore more options using the Harvard T.H. Chan School of Public Health dietary guide.
• The Human Body: It is an essential mineral stored primarily in your bones, muscles, and soft tissues, where it supports more than 300 biochemical reactions, including muscle function and energy production.
• The Earth’s Crust: As the eighth most abundant element on Earth, it is never found in its pure, elemental form. Instead, it is extracted from minerals like dolomite and magnesite, which are mined in large quantities across mountain ranges like the Alps.
• Water: Magnesium is highly soluble and plentiful in the hydrosphere, making it a major component of seawater, mineral waters, and many tap water supplies.

Homemade Healing Bath Salts

INGREDIENTS:

• 3 cups Epsom salts
• 1 cup baking soda
• Water to fill bath (as hot as you can stand without burning yourself)
• 40 drops lavender essential oil (or use 20 drops lavender essential oil and 20 drops juniper berry essential oil)
• Large glass jar

Directions:

• Combine dry ingredients and store in a closed container
• At bath time, add 1 cup of dry ingredients and the essential oil to the water
• Soak for 20–40 minutes (the longer the better)
