High Vitamin A Consumption May Increase Risks of Bone Fractures, According To A Recent Study

Overconsumption of vitamin A can boost the risks of bone fractures, states a study carried out on lab mice by scientists at the University of Gothenburg, in Sweden, and issued in the Journal of Endocrinology.

Vitamin A is essential for the human organism, but it might also be harmful in large doses

Vitamin A is vital for numerous biological functions, such as growth, sight, immune system and organs functionality. The human body is not able to make it on its own, so we have to take the required Vitamin A from the meat, dairy products, and vegetable consumption.

Some of the evidence has implied that those individuals taking vitamin A supplements might present a higher risk of bone fractures. Furthermore, earlier studies carried out in mice have demonstrated that a short-term vitamin A overdose causes a decrease in bone density and an elevated risk of fracture within the first or second week after intake.

But this study is the first to investigate the long-term health effects of doses commonly consumed by people who take vitamin A supplements. The scientists gave the mice doses 4.5 times as high as those prescribed for humans, observing that within eight days after administration the bone density decreased.

“Excessive consumption of vitamin A can be a growing problem as many more people now take vitamin A supplements. Vitamin A overdose may increase the risk of weakening bone disorders in humans, but more studies are needed to investigate this. In most cases, a balanced diet is perfectly sufficient to maintain the body’s nutritional needs for vitamin A,” the researchers have concluded in their study’s report.

In conclusion, the researchers at the University of Gothenburg revealed that high Vitamin A consumption increases the risks of bone fractures.
