Too long in the sun could be deadly as scientists reveal that too much vitamin D can lead to strokes or a heart attack.
While the health dangers of having too little of the sunshine vitamin are well known, the first ever study by the University of Copenhagen warned of the connection between high levels of vitamin D and cardiovascular deaths. Vitamin D is made by the skin in reaction to sunlight or found in oily fish, eggs, fortified cereals and spreads or supplements. It helps to regulate the amount of calcium and phosphate in the body keeping bones and teeth healthy.
A deficiency can lead to bone deformities, such as rickets or bone pain, and tenderness as a result of a condition called osteomalacia in adults. People taking too many vitamin D supplements over a long period can cause more calcium to be absorbed than can be excreted, with the excess deposited in and damage the kidneys. Excessive vitamin D can also encourage calcium to be removed from bones, which can soften and weaken them.
The new study published in the Journal of Endocrinology and Metabolism warned for the first time of the effect on heart health.
