The Heart Scan Blog: Food sources of vitamin K2 - 0 views

  •  
    Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.

Vitamin K2 and coronary plaque - Wellsphere - 0 views

  •  
    The vitamin K2 story, though still preliminary, is becoming increasingly interesting from the perspective of CT heart score reduction. The origin of this concept came from some unexpected observations. One, the observation that osteoporosis (lack of bone calcium that leads to fractures) arises from deficiency of vitamin K2. Two, deficiency of K2 leads to unrestrained calcium deposition in animal models, leading to heart attack in just weeks.

Too Little Vitamin D Puts Heart at Risk - 0 views

  •  
    Dec. 1, 2008 -- Getting too little vitamin D may be an underappreciated heart disease risk factor that's actually easy to fix.\n\nResearchers say a growing body of evidence suggests that vitamin D deficiency increases the risk of heart disease and is linked to other, well-known heart disease risk factors such as high blood pressure, obesity, and diabetes.

MedWire News - Oncology - Serum 25(OH)D levels linked to prostate cancer prognosis - 0 views

  • The researchers conclude: “This study shows a strong association between 25(OH)D levels and cause-specific mortality in patients with prostate cancer. The strength of the association indicates that prostate cancer patients can benefit from increasing the level of serum 25(OH)D if it is below 50 nmol/l.”

The Heart Scan Blog: "High-dose" Vitamin D - 0 views

  •  
    I stumbled on one of the growing number of local media stories on the power of vitamin D. \nIn one story, a purported "expert" was talking about the benefits of "high-dose" vitamin D, meaning up to 1000, even 2000 units per day. \nI regard this as high-dose---for an infant. \nJudging by my experiences, now numbering well over 1000 patients over three years time, I'd regard this dose range not as "high dose," nor moderate dose, perhaps not even low dose. I'd regard it as barely adequate.
