Could My Proximal Muscle Weakness Be a Result of Very Low Vitamin D Levels?

by Lenny

For the past 23 years I've been in and out of doctors' offices in order to determine the cause of the muscle weakness that I have in my shoulders/upper arms and upper thigh areas, all to no avail. I even had a muscle biopsy done when I was 14, but doctors found absolutely nothing wrong with me.

I am now 38, and only recently began to consider whether my condition may be due to low vitamin d levels. I recently had the VITAMIN D 25 HYDROXY - VITD25 test done, and my levels were <4 , which my doctor informed me is "VERY Low." She has now put me on 50,000 IU for the next 8 weeks; I've been on it for 2 weeks now, and I don't feel much of a difference yet, but I imagine that if this has been the problem tormenting me for the past 25 years, it's going to take more than 2 weeks to feel better.

I usually have difficulty walking up stairs, running, and occasionally falling down; are these possible symptoms of a vitamin d deficiency?

I'm so glad that I came across your website; thank you for sharing all of this information.

Hi Lenny,

The short answer is a resounding YES. And it could take up to 6 months to resolve. A level of 4 is not just 'very low', but 'virtually undetectable'. That's why it says 'less than 4' and not '4', because it does not detect it that low.

Please read my page on Vitamin D Therapy. With a level that low and for so long, I suspect you will regret taking such high dosages, and using the wrong kind of vitamin d, if you continue without taking the Vitamin D cofactors, and get on the right kind of vitamin d.
