How much vit D?

I just had another appointment with my LLND and finally my vit D is on the low side of normal at 26. It has literally taken me a few years to get it to this, as a side note I also have osteoporosis. At times I have had prescription vit D and if I don't take over the counter supplement it drops. Usually I have to take 2-500Iu's/day just to maintain it on the low end of normal. Then you read things like on Dr. Mercola's site saying you should never be below 35, most adults need 8000 iu's/day and that optimal levels are be between 50-70.
I am asking because my Dr. thinks a lot of my remaining symptoms are mycoplasma based and I have read that one of the best things you can do for that and viruses is to keep your vit D up. Also due to a lesion in my brain I recently lost my job that the regular Dr.s think it could be MS, that is a different discussion. However one natural thing that helps "MS" both with treatment and prevention is keeping a high vit D level so I have many reasons to keep it up but how high?
You guys know the rest of the story having been to countless Dr.s including endocrinologist and none of them know why it is so low. I think that it is either Lyme and friends or that I have a genetic defect.
Either way I am going to start taking 10,000/ day and will get tested in a month or so. Also I have never noticed any negative side effects from the vit d and as far as I know I don't have sarcoidosis.

Yes, you need to get tested to see where your levels are.

What did your Western Blot show when you tested for Lyme? Any positive bands?

okay - thanks for the clarification.

I test periodically - just to make sure the levels are where they should be.

I haven't got my test results in front of me....I think the lab I use - has a different unit of measurement.
If I'm remembering correctly - the bottom level of sufficient is 70 - I will have to check.

As a Caucasian I can produce as much as 15,000 IU's with 20 minutes of sunshine. It is best if you take some sunshine and combine Vit D. You should also consider oily fish such as salmon, cod liver oil, etc.

The darker skin color requires longer exposure to sunlight to get enough Vit D.

A friend of mine who has red hair and could pass for a vampire was having bone degeneration. We put him on 2,000 IU's per day. He reported that after taking a daily dose of Vit D he went for his first winter (midwest) without coming down with a cold or flu!

The people who live near the artic circle get their Vit D from fish, etc. No fresh fruit or veggies!

So, if you can combine sunlight with a daily supplement.

My level was a very healthy 78 without supplemenation before I developed thyroid disease in 2007 and well before I got bit by the tick last year.

Since then, I've found the need to start supplementing....and in increasing doses because I try to maintain my level between 70-80.

As of right now, I'm taking 5000 IU per day.

Nature Made Vitamin D3 in 1000 IU tablets works very well for me. I've read that the larger dose tablets/capsules aren't absorbed as well.

And, without a doubt, no one should be taking D2 that is often erroneously prescribed in mega doses by clueless doctors.

I take 15,000 IU of vit D3 in winter (north state), 10,000 IU in summer. This gets me in the 60-70 range in tests, I was at 35 naturally. So it satisfies the labs, but I FEEL NO DIFFERENT. Ya, weird.

I am outside a lot in the summer, but still need to supplement. Causation with some native, so kind of naturally tan, and dont burn much. 10,000 IU is a lot in the summer from what you guys use.
