Vitamin D sensitivity

You mean over the course of 5 weeks? What was your daily dosage?

Daily dosage starting with 5,000 and upping to 40,000 at some point.
UnFortunately I did not notice the side effects that strongly and could not relate to it until I took this high dosage, when my body was full of vitamin D :(

Ps: This was following the Coimbra protocol

Yeah, that's the problem with supplements, you can overdose. And vitamin D accumulates, it's not water soluble as the Bs and Vit C.

As @aaron_c suggested using an UVB lamp can help you with a vit D deficiency without the risk of overdose, and if you take a bit of sun, even better! 20-30 minutes every day in the good season can do a lot.

I have used a mix of sun + UVB lamp to recover a total Vit D deficiency back in 2015 and it worked just fine, in 5 months I went from 0 to 45. No side effects, besides a tan :)

If you want to read about it see this post:

Although I guess at this point, you don't really need any more vit D in your system!

good luck

Thought I'd bump this as I have an issue and wondered if any further info on this had come to light. A year or two ago I was diagnosed with vitamin D deficiency and given a megadose treatment to fix it, which it did. I was worried about taking it as previous experiences with supplements had left me feeling more ill, but for some reason that didn't happen with the megadoses.

Recently I decided to start supplementing with D3 again (small dose) but unfortunately suffered the same old reaction. I've tried different brands, I've tried tablets and capsules, every time the result is the same - I feel a new and quite unpleasant fatigue and worsening of symptoms.

Why would I get this from low dose over-the-counter D3 but not prescribed megadoses? Doesn't make sense to me.

I don't have an answer, but I also took vitamin D in the past without any (obvious) problems. These days, however, I am very sensitive and get a worsening of symptoms from a single dose that can last a couple weeks.

The only explanation for my experience is that my nutritional status has improved over the years, so my immune system may be stronger and better able to respond to vitamin D. But that's really just a guess...

My experience with Vitamin D is pretty weird, it also might chime with other members on this forum.

I was diagnosed with Mast Cell Activation Syndrome (MCAS) last Xmas and my doctor put me on a course of 1000iu daily Vitamin D (as well as 2 antihistamines).

Initially the Vitamin D started to do something positive - it seemed to be reducing my brain fog and has improved my tolerances to medications - but at the same time was worsening my CFS and achiness.

This doesn't make much sense to me - if the CFS and sensitivities are all being caused by MCAS, why would Vitamin D help some aspects of it while worsening others?

Part of me had hoped the Vitamin D might have been fixing an underlying issue (say mould or other infections) and that the "die off" was triggering my Mast Cells, but I feel this is unlikely.

My doctor (MCAS specialist) in our most recent consultation said the Vitamin D was intended to directly reduce my Mast Cell reactions (rather than anything underlying) and advised I keep taking it at 1000iu. But I literally cannot tolerate it now at all, it gives me really intense back pain and definitely worsens my symptoms, if feels like it's directly triggering my MCAS, so I've had to stop entirely.

I'm now at a loss as to what to make of it, and what if anything the Vitamin D helped while I was able to take it. And why I no longer can. If anyone has any insight here I would be massively grateful.

Recently I read something about the interaction between Vit D and DHEA, I suspect Vit D might require more adrenal energy than we can produce

I feel worse from all forms of Vitamin D supplements and the Sperti Vit D UVB sun lamp but I feel great from the sun. I just can't get enough sun in the winter where I live unfortunately so my D levels are low in the winter. I get lots of inflammation and fatigue from Vit D in any form other than the sun.
