Vitamin D is a nutrient that helps the physique take up and regulate calcium within the blood. So when an individual has an excessive amount of, it will probably result in dangerously excessive ranges of blood calcium, a situation referred to as hypercalcemia.
Vitamin D toxicity is uncommon and will typically go unrecognized, in response to Catharine Ross, a professor of diet and physiology and head of Dietary Sciences at Pennsylvania State College. Here is methods to spot vitamin D toxicity and what to do about it.
Signs and analysis
Signs of vitamin D toxicity are instantly associated to extra calcium within the blood, which might trigger nausea, vomiting, lack of urge for food, frequent urination, weak spot, and bone ache.
Over time, the additional calcium can type deposits within the arteries and smooth tissue as a substitute of within the bones. Finally, this may trigger kidney stones and will contribute to coronary heart injury.
“This is the major impact of acute vitamin D toxicity, and it may be occurring slowly in people taking high vitamin D for years,” says Paul Worth, Distinguished Professor Emeritus of Molecular Biology at College of California San Diego.
To diagnose vitamin D toxicity, a doctor will administer a blood check that may present how a lot calcium is within the blood. If an individual has vitamin D toxicity, then calcium ranges can be abnormally excessive.
Ross notes that taking constantly excessive ranges of vitamin D over lengthy intervals of time could not trigger obvious toxicity within the short-term, however could contribute to greater threat of frequent signs additional down the road.
Therapy
If an individual exhibits indicators of vitamin D toxicity, step one towards treating it’s to right away cease taking any and all vitamin D and calcium dietary supplements, in addition to lowering consumption of meals wealthy in vitamin D like salmon and cod liver oil.
Medical doctors might also administer medicines to assist the physique metabolize much less vitamin D and go extra calcium.
You may additionally be prescribed bone resorption inhibitors. These medicines are often used to deal with osteoporosis as a result of they forestall the discharge of calcium into the bloodstream. Nonetheless, Worth’s analysis has proven that bone resorption inhibitors might also forestall acute episodes of vitamin D toxicity.
These inhibitors, he says, could possibly be helpful to forestall calcification of sentimental tissue in sufferers who, for well being causes, cannot cut back their consumption of vitamin D.
For most individuals, although, the reply can be to easily cease your dietary supplements, which can enable your physique to course of the surplus calcium and, over weeks or months, return to regular.
Each day advisable worth

Our our bodies get vitamin D in two methods: by way of solar publicity and from sure meals. How a lot you want will depend on your age, in response to the Nationwide Institutes of Well being. For instance, adults require lower than individuals over 70, who produce much less vitamin D by way of their pores and skin.
The Nationwide Institutes of Well being suggest that almost all adults want 600 worldwide models (IU) every day to cowl their fundamental wants for bone well being. Nonetheless, for general well being, it is best to get someplace between 600 IU to 4,000 IU per day.
Fish is a good way to cowl your bases, whereas vegans and vegetarians can look to almond milk and mushrooms. Three ounces of fatty fish, like salmon, or a cup of portobello mushrooms will deal with your day by day vitamin D wants.
Ross says that in the event you sometimes devour the utmost advisable quantity — 4,000 IU — it will not damage you. However in case you are constantly reaching or exceeding this restrict for months or years on-end, that is when it could result in signs of toxicity.
Causes
Ross says that the vitamin D your pores and skin produces by way of solar publicity is difficult to quantify however normally, it is dietary supplements — not daylight — that ideas the scales in direction of toxicity.
When you get a extreme sunburn, for instance, you have to be extra involved about pores and skin injury than vitamin D toxicity. Furthermore, vitamin D deficiency is extra of a priority than toxicity.
That is very true for kids, who can develop rickets in the event that they’re vitamin D-deficient, resulting in smooth and poorly developed bones. The American Academy of Pediatrics recommends dietary supplements for infants who’re breast-feeding, or not getting ample vitamin D by way of components.
Finally, primarily based in your age, your way of life, and different elements, your physician will let you know whether or not you must take into account a complement.
Vitamin D supplementation on the rise – “vitamin d overload”
Between 2006 and 2014, the variety of individuals taking on 4,000 IUs day by day rose from lower than 0.5% to over 3%. That was in response to a 2017 examine within the Journal of American Medication, which pulled information from 39,000 members within the Nationwide Well being and Vitamin Examination Survey.
The examine additionally discovered that over the identical interval, these taking greater than 1,000 IUs per day jumped from lower than 1% to over 18%. This quantity isn’t identified to trigger quick well being issues, however the findings point out that extra individuals than ever are looking for out further vitamin D and could also be prone to overdoing it.
This doesn’t suggest that nobody ought to take a vitamin D complement. Aside from infants and people over 70 who seemingly require dietary supplements, individuals ought to get their blood ranges checked routinely to find out if dietary supplements are suggested.
When contemplating a vitamin D complement
When you determine you are eager about taking a vitamin D complement, learn the label, purchase from a good model, and examine to ensure that the product has been third-party examined for security and efficiency. Dietary supplements are solely loosely regulated by the Meals and Drug Administration.
“There are purified vitamin D3 supplements on the market at 10,000 IU per capsule,” Ross says, “so some manufacturers are, knowingly, not playing safe with the public.” Once more, it’s inadvisable to take greater than 4,000 IU per day for lengthy intervals of time.
She provides that the few research finished on consumption ranges this excessive had been short-term, lasting lower than a yr, so the results of taking 10,000 IU over the very long time is unknown. However, as with many issues in life, consuming something to extra might be not a terrific concept in your long-term well being.
Vitamin D analysis has obtained plenty of consideration lately, and plenty of potential advantages are rising. Dietary supplements are usually not essentially off the desk, however do not go in pondering extra is healthier — until you like kidney stones.
