Vitamin D repairs damage to the heart caused by diabetes

Vitamin D is an ‘inexpensive solution’ to drugs as scientists discover the sunshine supplement repairs and prevents damage to the heart caused by diabetes and high blood pressure.

The sunshine supplement stimulates the production of nitric acid, which is involved in regulating blood flow and preventing the formation of blood clots, according to the first study of its kind.


It also reduces ‘internal stress’ in the cardiovascular system, which could avoid heart-related incidents, the research adds.

Study author Dr Tadeusz Malinski from Ohio University, said: ‘There are not many, if any, known systems which can be used to restore cardiovascular cells which are already damaged, and vitamin D can do it. 

‘This is a very inexpensive solution to repair the cardiovascular system. We don’t have to develop a new drug. We already have it.’

Heart disease, which is any disorder affecting the organ or blood vessels, is the leading cause of death in adults in the US, resulting in one in four fatalities.

How the research was carried out 

The researchers analyzed heart cells taken from a group of Caucasian and African Americans.

They used special sensors to track the impact of vitamin D in these cells. 

‘This is a very inexpensive solution’  

Dr Malinski said: ‘Generally, vitamin D is associated with the bones. However, in recent years, in clinical settings people recognize that many patients who have a heart attack will have a deficiency. 

‘It doesn’t mean the deficiency caused the heart attack, but it increased the risk.

‘There are not many, if any, known systems which can be used to restore cardiovascular cells which are already damaged, and vitamin D can do it. 

‘This is a very inexpensive solution to repair the cardiovascular system. We don’t have to develop a new drug. We already have it.’

The researchers believe vitamin D may also be able to repair damage to other types of cells, such as those found in the brain after a stroke.  

The findings were published in the journal Nanomedicine.
