Vitamin D protects against death from heart disease and stroke

The evidence connecting Vitamin D deficiency with chronic disease continues to mount. Vitamin D deficiency has been linked to osteoporosis, multiple cancers, musculoskeletal diseases, thyroid disease, depression, and Type II diabetes. This is especially troublesome since several studies have found that most Americans are Vitamin D deficient.

Now, a long-term study has examined the connection between blood Vitamin D levels and death from cardiovascular disease – and the results were dramatic:

Serum Vitamin D levels were measured at the beginning of the study, and subjects were followed for 26 years. The researches found that those individuals with the highest blood levels of Vitamin D were 24% less likely to die from any cardiovascular disease, and 52% less likely to die from stroke.1

This new data supports results from the Framingham Heart Study, in which subjects were followed for 5 years – even after 5 years, those with low blood levels of vitamin D had a 60% greater risk of heart disease.2

How might Vitamin D affect cardiovascular health? Vitamin D localizes to most tissues and cells in the human body and is involved in several vital processes – to name a few - insulin production, immune cell function, inflammation, and heart contractility. Vitamin D deficiency could possibly lead to a pro-inflammatory environment, which would promote cardiovascular disease.3

How can you get adequate Vitamin D? Food sources of Vitamin D are scarce, and it is almost impossible for your body to produce sufficient Vitamin D from a safe amount of sun exposure, especially if you work indoors and don’t live in the tropics. So a Vitamin D supplement is your best bet. Remember – the standard dose of Vitamin D found in most multivitamins is not enough to assure adequate blood Vitamin D levels. In order to support all of Vitamin D’s important actions in the body, additional supplementation is necessary. Be cautious of Vitamin D supplements geared toward bone health – they may also contain excessive amounts of calcium, which can result in poor absorption of other minerals.

But isn't it contradictory that Vitamin D is found in highest concentration in the very foods that Followhealthlife warns against?

There is very little Vitamin D available from food. Our predominant source of Vitamin D is what the body produces in response to sunshine, and unless you are spending a lot of time in the sun, supplements are required.

Other than cod liver oil, I don't know of any foods that contain Vitamin D. Milk is supplemented with vitamin D.

Mushrooms contain 4 percent of the recommended daily allowance of vitamin D per serving, and this can be increased to 100 percent simply by exposing the mushrooms to sunlight for just five minutes. Vitamin D: Most ppl are deficient:-causes serious health problems. Vit D myths, facts and statistics

My name is Bibiana and I just finished reading your book. I have only a small concern about vitamins; It is necessary to purchase the vitamins you offer on your web-side? My family is large, I'm not working so I can not afford the prices for those vitamins and now I scared of don't have those vitamins on our system. I have regular vitamins that o brought over the counter and they have vitamin A and folic acid. Do you have a suggestion of what I can do to replace yours for the ones I can afford?
