I know for some time that my vitamin D levels aren't optimal (with 20 nmol/L or even below that during chilly seasons) and I recently found out that this condition runs in my family (my mum wasn't at all surprised and told me that she's taking D3 supplements for years now).
The last gastro. who took my vit. D levels acted rather strange ("well that's low but vitamin D is overrated" - something along those lines). That was 2 years ago and all my bloodtests since then showed low levels. I was on and off with vit. d3 tablets because often times I simply saw now change taking them and they didn't go down well for me for longer periods of time (because of all those added chemicals I suppose).
Fast forward to a week ago when my latest internal specialist acted totally different to that gastro. (whom I mentioned above) after she saw my current 20 nmol/L Vit D level. She told me to supplement asap and use liquid drops this time.
So this time I did my research and what I found was crazy for me:
a) Vit. D in liquid form is absorbed by the muccous barrier in your mouth and (according to studies) in doing so bypassing the tablets way through your stomach/intestines and gets absorbed much faster and - more importantly - is divided much better through your entire body. Researchers found out that liquid supplementation works for the body more like vit. D produced by sun-exposure whereas tablets are distributed less equally throughout the body.
b) This is actually important because almost all people with IBS symptoms that were tested for Vit D3 actually had a defiency (probably because of our rather bad fat absorption) and a lot of studies have now shown that supplementation in D3 indeed relieves IBS symptoms for a lot of people. Why is that you ask? I delved in deeper and aside from all the commonly known benefits of good vit D levels (bone/skin) this vitamine actually fights inflammation and supports the intestinal muccous barrier (screw that stupid gastro 2 years ago, doctors in Germany are seriously the worst).
and now the kicker:
c) Depending on Vit. D levels, it takes 4-6+ weeks (and even up to months) to see ANY benefits (because the body can only slowly raise nmol/L Vit D-levels) so eventhough I started taking D3 a few times, it couldn't have worked anyways because I was never taking them for long enough.
This is all really interesting I think. I'm now supplementing with drops (3000 units D3+added K2) every morning and will let you guys and gals know if I notice any difference (roughly 5 days in as of today). Worst case scenario: My skin might becomes less dry. But who knows? Maybe this change can actually help with some of my discomfort in the long run.
