In conjunction with a team from the Department of Epidemiology at Harvard School of Public Health, Edward Giovannucci, M.D., Sc.D., analyzed medical records and blood samples of 454 men, aged 40-75, all of whom have suffered from fatal heart diseases or had previously suffered non-fatal heart attacks.Researchers compared it with the medical records and blood samples of 900 men, still living, who never had any of the same heart complications.
What they found was that males with Vitamin D deficiency or those who merely meet the “intermediate” levels of Vitamin D, were more at risk of heart attack, compared to those with a healthy amount of Vitamin D in their diet. Researchers concluded that their results supported the idea that Vitamin D deficiency increases the risk of heart attack, and possibly death.
They added that their findings support the need to enhance Vitamin D levels in the body to reduce this problem.

Where Do We Get Vitamin D?
Vitamin D is an essential vitamin and is referred to as the “sunshine vitamin.” Sun exposure prompts our bodies produce vitamin D naturally. Sun exposure for as little as 10 to 15 minutes, 3 times a week is enough time to produce sufficient quantities of vitamin D. Unless you get very little “sun time,” there’s really no need to get vitamin D from your diet or Vitamin D supplements.
When vitamin D is manufactured in the body, the excess can remain in the body for months. During sunny months, you can increase your vitamin D levels by increasing your time in the sun.
Vitamin D plays a very important role in your body’s health by promoting the absorption of magnesium and calcium. These substances are vital to the healthy development of bones and teeth. Vitamin D also helps to keep adequate levels of phosphorus and calcium in the blood.
The Difference Between Vitamin D2 and Vitamin D3
Vitamin D2, named ergocalciferol, is produced by irradiating plants to produce yeasts. Vitamin D3 comes from animal sources. Its manufacturing base can come from cattle brains, sheep wool, hides and fish.
