Vitamin D and omega-3 improve vessel health

  • Vitamin D reduces heart and circulatory issues in OA

Because vitamin D helps maintain bone calcium levels, it might also have broader health effects in osteoarthritis (OA). Doctors in this study evaluated vitamin D levels in 4,570 people with OA who had participated in the long-term National Health and Nutritional Examination Survey study.

Those whose vitamin D levels reached or exceeded 75 nanomoles per liter of blood (nmol/L), or 30 nanograms per milliliter (ng/ml), were less likely to have died from any cause except cancer, including all heart and circulatory issues, compared to those with lower normal levels, and to the 65 percent in the study who were low or deficient in vitamin D.


  • Optimal omega-3 dose for lowering BP

There is consistent evidence that omega-3 fatty acids, especially DHA and EPA, support lowering elevated blood pressure (BP). But studies to date have not identified an ideal dosage range. To answer the question, doctors reviewed 71 placebo-controlled BP trials covering 4,973 men and women, aged 18 to 86, some of whom had high BP and/or imbalanced lipids.

Overall, daily doses between 2 and 3 grams of omega-3 fish oil reduced systolic BP by an average of 2.61 mmHg, and diastolic BP by 1.64 mmHg. Doses above 3 grams per day did not lower BP further in those with normal BP, but those who were elderly, or those who had high blood pressure, or imbalanced lipids, saw a greater BP-lowering response to higher doses of omega-3s.
