Effects of vitamin D for heart failure far from 'stunning'

Conclusion This study showed that taking daily vitamin D3 supplements for a year did not improve the ability of people with chronic heart failure to walk further, but did improve elements of their heart function. The study was well designed, but larger studies are needed to confirm the findings more definitively. The main limitations of the research include the fact the main focus was on men, its relatively small size, and an absence of measures relating to the main symptoms of the condition. The study was not able to tell us whether the heart change improvements seen enhanced quality of life in terms of breathlessness, tiredness and swollen ankles. There were no improvements seen in walking distance. If you think you may be vitamin D deficient, talk to your doctor about whether supplements may help, or whether getting more sunlight may be an equally effective and more attractive approach. If you take vitamin D supplements, do not take more than 25 micrograms (0.025mg) a day, as it could be harmful, though taking less than this is unlikely to cause any harm.
