NEW YORK (Reuters Health) - Consuming a large amount of vitamin A may reduce bone thickness, leading to bone weakness and increased fracture exposure, according to a recent scientific study published in the journal Endocrinology.
According to the website of the Daily Mail, the study found that eating vitamin A continuously, at levels equivalent to 13 times the recommended daily dose, causes significant bone weakness.
The researchers pointed out that people should be wary of excess supplements, especially vitamin A in their diets.
Vitamin A is an essential vitamin for many biological processes including growth, vision, immunity, and essential organ functions. Our bodies are not able to make vitamin A. But a healthy diet, including meat, dairy products and vegetables, Be sufficient to maintain the body's dietary needs.
Some evidence suggests that people who take vitamin A supplementation may increase the risk of bone damage. Previous studies have shown that a short dose of vitamin A leads to reduced bone thickness and increased risk of fracture after only 1-2 weeks .
In the study, Dr. Olfer Lerner and colleagues at the Sahelgrenska Academy at the University of Gothenburg reported that mice who were given high doses of vitamin A over a longer period of time experienced bone fragility only after 8 days.
Dr Ulf Lerner warned that excessive consumption of vitamin A as many people are now taking vitamin supplements, pointing out that a balanced diet is sufficient to maintain the body's nutritional needs of vitamin A.
