Low vitamin D even with supplementation

Did a lot of digging here on forums for low vitamin D levels and Lyme. So far the best I can sum it up is that 85% people in general have low vitamin D so I'm not exactly sure how this can be a Lyme symptom. Although, many people here have posted about this so it might either be solely a nutrition thing and/or a Lyme symptom. Also, Lyme can affect the liver's ability to manage the toxins which can affect vitamin D absorption (I believe).

Here's what may also be proof, why would I have 28 out of 100 (in range is 30 out of 100) for total vitamin D level if I've been taking a multivitamin with 100% vitamin D value for the past 10 years? I would figure I would be at around average level just purely on this fact. I also take 30 minute walks outside everyday so not quite sure how else low vitamin D could be explained except that it's from Lyme.

It isn't a Lyme symptom, it's just a needed nutrient that so many people are low on and it helps the immune system, among other things. Lyme can just mess up your body's ability to work with it sometimes, as can happen with any nutrient, causing you to have too much or too little.

My LLND recommends between 5,000 and 10,000 IU of Vitamin D daily, and the United States Government only recommends you take 400 IU's a day. That is what is typically in a multi-vitamin, 400 IU's daily which our governmnet calls 100% of your daily value! They are short on that by a long shot. You need to take 13 times that amount to just get 5000 IU which is what a lot of doctors recommend. I am taking 5000 IU's daily and I am still short on the level in my body my doctor said. Ask your LLMD what you can do to increase your level.
