As magnesium competes with calcium at doses higher than 250mg, if your calcium levels are already low it might cause you to develop a calcium deficiency. Generally, taking both minerals in their daily recommended amounts is completely fine.
Calcium and magnesium work well together but if one is consumed in excess to the other it may lead to imbalances that can lead to health complications.
Magnesium is required for the production and release of parathyroid hormone, so when magnesium is too low, insufficient parathyroid hormone is produced and blood calcium levels are also reduced (hypocalcemia). The hypocalcemia is described as "secondary" because it occurs as a consequence of hypomagnesemia.
High doses of magnesium from supplements or medications can cause nausea, abdominal cramping and diarrhea. In addition, the magnesium in supplements can interact with some types of antibiotics and other medicines.
A tight control of magnesium homeostasis seems to be crucial for bone health. On the basis of experimental and epidemiological studies, both low and high magnesium have harmful effects on the bones.
"Adequate levels of magnesium in the body are essential for the absorption and metabolism not only of vitamin D but of calcium as well," Dean states. "Magnesium converts vitamin D into its active form so that it can help calcium absorption.
The benefits of magnesium supplementation in healthy individuals aren't clear, but Dr. Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.
UL: The Tolerable Upper Intake Level is the maximum daily intake unlikely to cause harmful effects on health. The UL for magnesium is 350 milligrams from supplements only. High-dose supplements can lead to diarrhea, nausea, and cramping in some people.
Magnesium has a direct impact on hair growth. It regulates hair follicle production and the overall hair growth cycle, making it an essential mineral for healthy hair growth. When magnesium levels are low, hair follicles go into a resting phase and stop producing new hair, leading to hair loss.
This mineral helps in maintaining function in our nerves and muscles and supports a healthy immune system. It also plays a role in keeping our heartbeat steady and bones strong. Current recommended daily requirements of magnesium for adults 51 and older is 420 milligrams for men and 320 milligrams for women.
Net absorption of dietary calcium is also reduced to a small extent by intakes of caffeine and phosphorus and to a greater extent by low status of vitamin D [9-11].
Magnesium frequently acts as natural antagonist of Calcium. The two cations compete in the modulation of muscular contraction, as well as in the regulation of several enzymatic reactions involved in energy metabolism, signal transduction and brain activity [13, 14].
Specific minerals are needed by the melanocytes to make pigment (a process called “melanogenesis”), such as copper, zinc, iron and calcium (R,R). Other important minerals for healthy hair are selenium and magnesium. People who are deficient in these important minerals have more risk of their hair turning gray.
Dr. Cheruki explained that "Magnesium plays an important role in energy production, helping to break down carbohydrates into energy for the body. This energy is essential for healthy hair growth as it helps to promote cell regeneration and circulation in the scalp, leading to thicker, healthier-looking hair.
Regulates Calcium Levels: Magnesium helps to regulate calcium levels in the body, which is important for healthy hair growth. Calcium buildup in the hair follicles can lead to hair breakage and hair loss, and magnesium helps to prevent this by ensuring that calcium is properly regulated.
Magnesium for sleep
Some studies have found that magnesium supplements can: Make it easier to fall asleep. Improve sleep quality. Reduce symptoms of restless legs syndrome, which can interfere with a good night's sleep.
Intravenous calcium, diuretics, or water pills may also be used to help the body get rid of excess magnesium. People with renal dysfunction or those who have had a severe magnesium overdose may require dialysis if they are experiencing kidney failure, or if magnesium levels are still rising after treatment.
Magnesium deficiency is diagnosed via a blood test and sometimes a urine test. Your doctor may order the blood test if you have symptoms such as weakness, irritability, abnormal heart rhythm, nausea and/or diarrhoea, or if you have abnormal calcium or potassium levels.
When taken in very large amounts (greater than 350 mg daily), magnesium is POSSIBLY UNSAFE. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
In general, magnesium seems to have minimal side effects, and taking low doses is unlikely to cause much harm. According to the Institute of Medicine, healthy adults can safely take up to 350 milligrams of supplemental magnesium daily. Anything at or below that level is unlikely to cause any adverse health effects.
In order for bones to grow and to be maintained, several nutrients are needed [2]. For the prevention of bone loss, and thus the development of osteoporosis, calcium and vitamin D are well known. Another nutrient that plays a role in bone health is magnesium.
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
