I take vitiam D in pill form and I take one pill in the morning and two at night time and I have never felt stronger, energetic or happier in my life.
One pill contains 1000 IU and I am gradually and slowly going to 5000 IU a day, so that my body can gets use to it.

Things that D3 can help with:

It can reduce inflammation that contributes to MS symptoms. It is also the vitamin, when activated by your kidney, that sends a message to your gut to absorb Calcium [Ca]. This is what is used to send a nerve impulse from one nerve to the next. It is also what is used to allow for myosin to connect with actin....aka muscle movement to happen.

So is D3 going to regrow the myelin? No
If you are low on Calcium it can help increase the calcium and thus will help nerve conduction and muscle movement. This is IF you take fat soluble D with fat and get your HDL numbers up so you can store it.

It is kinda like you have engine problems {myelin in MS} and then you are also low on oil {low Ca}. If you add D3 you are not fixing the engine but you are increasing the oil level which, if not addressed, will contribute to your problems.

I take Vitamin D and Fish oil along with my regular megadose vitamin and my stress B complex. I don't know if it's helping, but it certainly isn't hurting anything.

I've been on as much as 100,000 IU a week of vitamin D for over a year. It was just reduced to 50,000 IU a week after my level got up to 35. I cannot say I notice any difference. Oh well ...

*sigh*

One question for those that took the D3.

Did you bring your FAT numbers UP?
ie Palmitic acid, stearic acid, omega 3, 6 and 9 (aka oleic acid)

The fat is what you need to absorb and store D3, for later use. It is what is needed to make steroids, sex hormones and thyroid hormones (all have been looked at in connection with MS) not to mention the myelin itself which is primarily fat, some protein and B vitamins.

So where is your HDL Fat levels??
