I exercise regularly and eat a lot but my muscle is not that developed though I work out also. Maybe I lack vitamin D.

I had no ides about Vitamin D. Thank you for your kind article.

MFB - You should probably get another level done in a month or two to see if you're getting enough vitamin D. With a level that low, you can easily have more muscle weakness than you would otherwise.


So interesting. I just got my blood work done and my Vit D level is 15. I am active, but I'm tired all the time. When I exercise, my muscles shake, but I push myself to gain strength constantly. I tend to get injuries easily and my joints aches, sometimes severely. I usually soak in epsom salt and it helps temporarily. So, I'm hoping that this is the cause and that ill see some improvement. I look forward to the two-three week mark and look for noticeable change in energy level and the way my muscles/joints feel. I'm a raw vegan and live in cold climate - Pacific NW, so I have to watch it. It's just this is the first time I've checked my levels. This means I have to be more diligent about vit. D consumption, maybe taking 1000 u daily. I'm learning from this blog that I cant overdose to toxic levels even If taking them daily. BTW, I went out and bought a new bottle of 1000u of vit D with only 50 tabs, even though I have a bottle of liquid vit D after adding your blog. That way I can break open 2-3 a day and use them up in a few weeks.

Thanks for sharing your experience and insights.

Seasonal effective disorder and depression have all been linked to low vitamin D levels. Many physicians are now recommending supplementation to boost these levels, especially for those living in northern climates where winter sunlight levels is low.

In March end my blood level revealed Vitamin D level below 5.0.Medication plus UV rays from sun has given me relief. I am supposed to see the doctor after 3 months i.e. end of June.

Those pains which I thought will be carried to cemetary have now vanished.

Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement.


I use to be one of the millions suffering from vitamin D deficiency. My Dr. did blood work and over several months increased my vitamin D intake to 8000 I.U (international unit) per day. Don't increase to this much without Dr. approval. It has made all the difference in the world. My sluggish, tired muscle feeling is gone and I'm back to running mini-marathons. Thanks for the great article.

Very awesome information about Vitamin D. Should "normal" people who do not go to gyms take vitamin D as a daily requirement?


I just found this blog. Great place to improve my research on vitamin D deficiency.
