It is already known that vitamin D deficiency weakens bones, but when it comes to heart health the role that vitamin D can play remains unclear. Vitamin D deficiency can be linked to heart disease and an increased risk of high blood pressure (hypertension).
However it is too early to say whether vitamin D deficiency causes high blood pressure or whether vitamin D supplements may have a role in treating high blood pressure. Much research is still needed on this.
What remains certain is that vitamin D is a very important nutrient for human health.
Doctors advise that a person between the ages of 19 and 70 should take about 15 micrograms of vitamin D a day, while an elderly person over the age of 70 should consume about 20 micrograms a day. But some doctors raise the question of whether these levels are enough and think that taking a higher dose would help more people.
But scientists in the field of medicine recommend that adults avoid taking more than 15 micrograms per day, as it can have toxic effects. If you are concerned that you are taking more or less vitamin D, contact your doctor. He may recommend a test to check the level of vitamin D in the blood.
Controlling for vitamin D deficiency is also important in people with dark skin. Dark skin has higher levels of melanin, the pigment that gives skin its color. The more melanin you have, the harder it is for your skin to produce vitamin D from sunlight.
People who can benefit from testing for vitamin D in their blood are:
-People who do not spend much time in the sun.
-The elderly.
-People with certain health conditions, who have difficulty absorbing vitamin D./AgroWeb
