vitamin C
New research says that men who take vitamin C with high doses can face double the risk of kidney stones. Although these findings do not directly prove that vitamin C causing kidney stones, but these findings raise the question of whether large doses of vitamins is harmful to the body.
“It’s important for people to realize that there may be risks associated with taking high doses of vitamin C,” explains researcher Agneta Akesson, a professor of the Karolinska Institute in Stockholm, Sweden.
“Those who have a history of kidney stones should consult their doctor before taking supplements to choose high doses of vitamin C,” he added, as reported from Health24.
The researchers suspect that large amounts of vitamin C can increase the risk of kidney stones as the body break down into a substance called vitamin oxelate, which is a component of the stone.
In the new study, published online in the journal JAMA Internal Medicine, researchers tracked more than 23,000 Swedish men aged between 45 and 79 years in 1997. The researchers followed the men who had not previously been diagnosed with kidney stones until 2009.
Approximately 900 of the men who regularly consume 1,000 milligrams of vitamin C dose and 31 of them (approximately 3 percent) developed a kidney stone condition. Of the remaining larger group, less than 2 percent of kidney stones.
After the researchers adjusted statistics so they would not be influenced by factors such as high or low amounts of vitamin C than men with a certain age, educational level and body weight, the researchers found that those who took high doses of vitamin C supplements have increased risk of stone kidney between 1.7 and 2.2 times.
