No, typically high dietary salt (sodium chloride) intake tends to deplete magnesium levels by increasing its excretion, but soaking in magnesium salts (like Epsom salts) can increase body magnesium, though scientific evidence on skin absorption effectiveness is mixed. Certain mineral salts, like Celtic salt, naturally contain magnesium, but the primary interaction with regular salt is depletion.
“There is evidence that eating too much salt can lead to depletion of other ions, such as magnesium,” Kirabo said. “In this new study, we deliberately caused magnesium depletion in mice, activating this inflammatory pathway, and the result was hypertension.”
For pregnancy, the best magnesium supplements are easily absorbed forms like Magnesium Glycinate (great for sleep/relaxation, gentle) or Magnesium Citrate (good absorption, helps constipation), while Magnesium Oxide is poorly absorbed. Always consult your doctor before starting any supplement, as they can advise on the right type and dosage (around 350-400mg daily), often finding it helps with leg cramps, sleep, and blood sugar, but dietary sources are key.
Health Risks from Excessive Magnesium
Although the risk of acquiring too much magnesium from food is low among healthy people, high doses of magnesium from dietary supplements or medications can cause diarrhea, nausea, and abdominal cramping.
Mild hypermagnesemia (less than 7 mg/dL) - Asymptomatic or paucisymptomatic: weakness, nausea, dizziness, and confusion. Moderate hypermagnesemia (7 to 12 mg/dL) - Decreased reflexes, worsening of the confusional state and sleepiness, bladder paralysis, flushing, headache, and constipation.
Common causes of low magnesium include:
Effects of Magnesium on the Fetus
Magnesium supplementation has a positive impact on fetal development, promoting healthy growth. Oral magnesium intake helps enhance fetal blood circulation, ensuring better oxygen and nutrient supply to the baby.
If you want to take magnesium for anxiety, magnesium glycinate and magnesium L-threonate are good options. They're easily absorbed into the bloodstream, and they include amino acids that help with relaxation.
With Magnesium L-Threonate
Scientists from top-tier universities developed Magnesium L-Threonate, aka “the brain magnesium”, to specifically cross the blood-brain barrier.
Even though Biel didn't specify the reason for the bath, epsom salt is known to ease stress, relax the body, help muscles and nerves function properly and eliminate toxins.
Your body needs magnesium to function normally. Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms.
When consuming salt during pregnancy (or anytime), it's best to limit processed foods and reach for natural salts, such as Celtic sea salt or Himalayan pink salt. So, which one is better? Either of these natural salts is suitable to consume during pregnancy.
Epsom Salt, rich in magnesium sulfate, provides essential minerals that promote muscle relaxation, stress relief, and detoxification.
To promote optimal absorption, it's important to be mindful of what you eat and drink alongside magnesium supplements. Foods and drinks high in fiber, phytic acid, phosphoric acid, alcohol, and caffeine can interfere with how well your body uses magnesium.
The amount of calcium that your body loses via urination increases with the amount of salt you eat. If calcium is in short supply in the blood, it can leach out of bones. So a diet high in sodium could have an additional unwanted effect—the bone-thinning disease known as osteoporosis.
Studies have indicated that magnesium supplementation can lower cortisol levels in individuals experiencing chronic stress. This reduction can lead to improved mental clarity and emotional resilience, allowing individuals to face daily challenges with a calmer mindset.
Magnesium supports focus, calm, and better sleep in children with ADHD. The best forms for kids include magnesium glycinate, citrate, and chloride.
However, if you ingest high doses of any magnesium supplement, you might experience side effects, such as diarrhea, gastrointestinal irritation, nausea, vomiting and worse. If too much magnesium builds up in your body, as can happen if you have kidney disease, you can have serious side effects.
This is because when you have kidney problems, your body might not be able to get rid of magnesium as well. As a result, magnesium can build up in the blood and cause dangerous side effects, like dizziness, low energy, nausea vomiting, and muscle weakness.
DBL Magnesium Sulfate Concentrated Injection may cause blurred or double vision in some people. If you have any of these symptoms, do not drive or operate machinery. Tell your doctor if you drink alcohol.
The good news is that with a little careful planning, you should be able to get the magnesium your body needs — 400 to 420 milligrams per day for adult men and 310 to 320 milligrams for women (more if pregnant or breastfeeding).
Symptoms of magnesium deficiency may include:
But some foods and drinks can make it harder for your body to absorb magnesium or even increase magnesium loss, so timing and pairing matter.
The causes of magnesium deficiency include: Chronic diarrhea. Frequent vomiting. Malabsorption, due to a digestive condition, such as inflammatory bowel disease (IBD), or a procedure that removes part of the small intestine, namely weight loss surgery.
