Fantasy: Getting magnesium by way of your pores and skin is more practical than oral dietary supplements

Yep, magnesium sprays, flakes, and salt baths exist—however they “aren’t the reply,” says Kelsey Costa, MS, RDN, a registered dietitian and vitamin guide for the Nationwide Coalition on Healthcare.

“The declare that magnesium absorbed by way of the pores and skin (transdermal) surpasses oral dietary supplements in effectiveness isn’t backed by stable, scientific proof,” Costa says, pointing to a 2017 research in Vitamins that additionally “can not but advocate the appliance of transdermal magnesium.” Additional, she believes the hype round this pattern is pushed by advertising campaigns, not science.

Fantasy: Oral dietary supplements are the most effective route for getting extra magnesium

Whereas oral dietary supplements may be useful, they’re additionally not essentially the finest route. “A number of the finest magnesium-rich meals are nuts and seeds reminiscent of almonds and cashews, cooked spinach, and baked potatoes with pores and skin,” says Sarah Schlichter, MPH, RDN, a registered dietitian with Diet for Operating.

Fantasy: Everyone seems to be in danger for magnesium deficiency, so we must always all take dietary supplements

To be clear, magnesium is an important mineral, and almost half of Individuals eat lower than the estimated common requirement, Costa shares. On the similar time, she believes “it’s not correct to say that everybody is universally poor and requires supplementation.”

Facet word: Those that have sure persistent sicknesses, take sure drugs, don’t eat many magnesium-rich meals (like darkish leafy greens, complete grains, nuts, and legumes), and who drink closely are at a better threat of deficiency, Costa provides, referencing the research linked above in addition to one in Open Coronary heart. Some examples of these drugs embody diuretics, chemotherapy medication, and aminoglycoside antibiotics.

Sadly, testing may not at all times provide the proper reply on whether or not you’re poor, both. “Routine blood exams might not at all times mirror an correct magnesium standing because the mineral is especially saved in tissues and bones, and sure kinds of deficiency should present regular blood ranges,” Costa explains.

Fantasy: Physique odor is an indication of magnesium deficiency

These two merely shouldn’t be equated, in keeping with Schlichter.

Jaclyn London, RD, a registered dietitian, agrees. She posted a duet on TikTok with one other creator who claimed her physique odor signaled she was poor in magnesium. Additional, the creator made a magnesium water spray to make use of as a substitute of “cancer-causing deodorant” (*cough cough* one other fantasy!).

@jaclynlondon #duet with @Ali is Toxin Free #magnesium PLEASE DON’T fall for loopy 💩like this!! (And should you don’t odor nice at the moment, nicely…perhaps let’s simply begin with a smart bathe & see the place we land.???) Right here’s the deal: You’re most likely NOT magnesium poor. Right here’s why 👇 •Insufficient consumption of magnesium is quite common— >50% of U.S. adults aren’t getting sufficient (PMID: 29387426)… •…however signs of acute magnesium DEFICIENCY are literally fairly uncommon. That’s b/c our our bodies retailer magnesium in bones & tender tissue cells (about 25g), & &lt1% of complete physique magnesium is saved in blood serum ranges which can be tightly regulated by your kidneys. In different phrases: Even if in case you have low magnesium ranges on a blood take a look at, that doesn’t inform you a lot about your physique’s personal complete magnesium standing (since a blood take a look at is simply measuring that 1% serum magnesium). •For many typically wholesome individuals: Sustaining magnesium homeostasis=your kidneys will naturally excrete much less urine if/when serum magnesium is tremendous low, as they do in response to low ranges of all electrolytes (together with sodium, potassium, & chloride). •Signs of precise, acute magnesium deficiency are extraordinarily severe, & embody lack of urge for food, nausea, vomiting, fatigue, & weak spot, & can progress into numbness, tingling, muscle cramps/contractions, & irregular coronary heart rhythms.

Backside line: Regardless of what’s everywhere in the web, I’m actually not involved you’re in danger for extreme magnesium deficiency— it’s unlikely at finest. HOWEVER… •It’s possible you’ll be in danger for magnesium inadequacy on account of not consuming sufficient magnesium-rich meals.

Fantasy: Consuming an excessive amount of magnesium-rich meals can result in toxicity and severe well being issues

This fantasy has a caveat, like among the others. “Whereas it’s attainable to eat an excessive amount of magnesium, it’s extremely unlikely by way of food plan alone,” Costa says. “The kidneys are environment friendly at regulating ranges of magnesium within the physique, and extra quantities are excreted in urine.”

That stated, should you do take dietary supplements, watch out—and at all times seek the advice of a medical skilled previous to beginning any new complement routine. “Massive doses of magnesium, particularly in quantities exceeding 350 milligrams per day, can doubtlessly result in dangerous penalties,” Costa provides. A number of the penalties she notes are irregular heartbeat, low blood stress, confusion, and different circumstances that may be deadly.
