Dear Dr Cannell: Vitamin D, fatigue, and quality of life

Posted on: May 24, 2013   by  John Cannell, MD


Dear Dr. Cannell:

Is there any concrete research that suggests that vitamin deficiency is related to fatigue and tiredness?

My vitamin D levels are at 13 ng/ml (33 nmol/L), which is deficient, could you provide me with links that shows that vitamin can help with fatigue and well-being?

I’m from the UK, we hardly get any sunshine.

Thank you

    My love affair with vitamin D began in 2010 when I started taking 5,000 IU of D per day and my bone pain, low energy, and chronic blah feeling disappeared. That is not to say that all people who have these problems and start taking D will experience the same relief, but I am certain there are many others out there whose fatigue and depressed mood are directly caused by a vitamin D deficiency.
