What Are Kidney Stones?
The main function of the kidneys is to clean blood and expel urine. When the blood is filtered, urine is generated, and it passes down into the ureters and is stored in the bladder before it leaves the body through the urethra. Kidney stones can develop if the urine holds more crystal-making substances than they can be diluted by the urine.
Vitamins and Supplements for Kidney Stones
Vitamins and supplements such as vitamin C, vitamin D, magnesium, potassium citrate, and calcium are used to help with kidney stones.
1. Vitamin C
Vitamin C is metabolized into oxalate, and it augments the risk of kidney stones. Thus, it is normally advised that those in danger of kidney stones should shun vitamin C doses higher than 1,000 mg per day.
On the other hand, a 1999 study in which 85,557 people were prospectively examined concluded that routine restriction of vitamin C in preventing stone formation seemed unwarranted.
Cautious advice would be to maintain vitamin C intake to less than 1,000 mg per day if you are in danger of kidney stones.
2. Vitamin D
Vitamin D deficiency is common. There is also an indication that those who are in danger of kidney stones are more liable to be deficient in vitamin D than others. Some are apprehensive that vitamin D supplementation may augment the danger of kidney stones.
However, most evidence suggests otherwise. A 2013 study indicated that short-term nutritional vitamin D filling in stone formers with vitamin D deficiency too does not seem to augment urinary calcium excretion. Likewise, a 2016 study revealed that supplementation with vitamin D did not augment the hazard of kidney stones.
A 2019 study allotted patients 50,000 IU weekly and discovered that patients lacking in vitamin D who supplemented with usual doses, did not unavoidably undergo an upsurge of kidney stones.
It is concluded that a person who is lacking in vitamin D but in danger of kidney stones may care about taking vitamin D but should also catch on to dietary precautions.
Magnesium hinders calcium oxalate crystal formation in the urine. A 1982 study stated that taking magnesium caused a ten-fold decrease in stone formation in afflicted people.
Moreover, a 1988 study demonstrated that lesser levels of magnesium in the urine augmented the danger of developing kidney stones. This was repeated by a 2020 study, which exhibited that low blood levels of magnesium were linked to an augmented danger of kidney stones.
4. Potassium Citrate
Potassium citrate combines with urinary calcium and prevents the formation of calcium stones. Furthermore, the citrate connects to calcium-oxalate and prevents calcium stones, if present, from expanding.
A 2009 study in Pediatrics showed that potassium citrate was a successful treatment in the avoidance of kidney stones. A 2010 study too displayed the efficacy of potassium citrate in thwarting kidney stones.
Usually, a low-calcium diet was advised to help stop kidney stones. Superficially, this would seem to make sense, but research does not confirm this.
Because a low-calcium diet causes an upsurge in the intestinal absorption of oxalate, bringing about more kidney stones. In real life, diets elevated in calcium-rich foods essentially seem to stop the formation of kidney stones.
