It is well established that low levels of vitamin D can result in bone disease, equivalent to rickets in children and osteoporosis in adults. But it may also increase the risks of heart attack and premature death.
The Endocrine Society defines vitamin D deficiency as a blood level of lower than 20 nanograms per milliliter (ng/mL), while vitamin D deficiency is 21 to 29 ng/mL. The optimal level is 30 to 100 ng/mL.
In a study published in October 2021 Journal of the Endocrine SocietyThe researchers identified 19,092 individuals who showed vitamin D deficiency on at the least two tests and who never had a heart attack. All were divided into three groups. People in group A weren't treated, and their blood levels remained below 20 ng/mL. Those in group B received vitamin D supplements that increased their levels from 21 to 29 ng/mL. Those in group C took enough supplements to lift their levels to 30 ng/mL or higher.
The researchers found that group C had a lower risk of heart attack than the opposite two groups. However, people in groups B and C (who took all supplements) had a lower risk of death from any cause than people in group A, who were vitamin D deficient. connection? Other evidence has linked low blood levels of vitamin D to cardiovascular risk aspects, equivalent to hypertension, diabetes, obesity, and chronic kidney disease.
