I am a little more than 3 months post-op and I just got blood work back from the doc. She recommends taking 2000iu of Vitamin D3 daily. What is this and is it going to help me not feel tired all the time?

D3 is vital to your immune system, and yes you will feel MUCH better. Our bodies naturally produce D3 from sun exposure, I live near Seattle Washington and Washington has the highest rates of multiple scelrosis in yhe nation, which is directly linked D3 deficiency. I've taken it for awhile (even before surgery) and have niticed a boost in my energy and overall feel better.

I was feeling a little "low", got my D tested and it was very low... started taking large doses (prescribed by my Dr) then regular over the counter D3. It made me feel much better. I use a lot of sun screen, this can cause low D.

Most people are deficient in Vit D 3. It's something doctors only recently started testing for.

I take 50,000 units once per week. That seems to be the best way it's absorbed.
