Beloved,
I wish above all things that thou mayest ...be in health...

"Cholecalciferol, also known as vitamin D3, can significantly restore the damage to the cardiovascular system caused by several diseases, including hypertension, diabetes and atherosclerosis, according to new research from Ohio University.
“Generally, vitamin D3 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 of D3,” said Ohio University’s Professor Tadeusz Malinski.
Professor Malinski and his colleagues, Alamzeb Khan and Hazem Dawoud, have developed unique methods and systems of measurements using nanosensors to track the impacts of vitamin D3 on single endothelial cells, a vital regulatory component of the cardiovascular system.
A major discovery from these studies is that D3 is a powerful stimulator of nitric oxide, which is a major signaling molecule in the regulation of blood flow and the prevention of the formation of clots in the cardiovasculature. Additionally, D3 significantly reduced the level of oxidative stress in the cardiovascular system.
Most importantly, these studies show that treatment with D3 can significantly restore the damage to the cardiovascular system caused by several diseases, including hypertension, atherosclerosis, and diabetes, while also reducing the risk of heart attack." SciNews
little as 5 to 30 minutes in direct sunlight with your face, arms, legs or back exposed two times a week between 10 a.m. and 3 p.m. in the summer, fall and spring can synthesize enough vitamin D3 to supply your needs, the Office of Dietary Supplements reports." SFgate
"Vitamin D is commonly referred to as the "sunshine vitamin" because it's the only vitamin that can be made by the human body from sun exposure. It plays a very important role in health. The active form of vitamin D is known as vitamin D3 or cholecalciferol. The recommended adequate intake (AI) level for vitamin D3 is 5mcg daily for adults 31 to 50 years old. After age 50, the AI increases to 10mcg daily. Very good food sources of vitamin D include include seafood, fortified milk, cereals and soy products." LS
“It doesn’t mean that the deficiency caused the heart attack, but it increased the risk of heart attack.”
“We use nanosensors to see why D3 can be beneficial, especially for the function and restoration of the cardiovascular system.”

"Spending time in sunlight is one of the most effective ways of raising your D3 levels. Awareness of the potential dangers of skin cancer, less time spent working outside and liberal use of sunscreen have decreased sun exposure in industrialized countries such as the United States. Spending as
