I have been trying to follow along with Dr Jack Kruse (although he makes it difficult!) but from what I have read, I have to agree with him that supplementing Vit D is a Very Bad Idea.
In a nutshell, humans were not meant to get Vit D orally, we are meant to get it through our skin. It doesn't work the same to take it orally.
Simply, it seems like Vit D is how we absorb the energy from the sun. This energy is crucial for driving our circadian rhythms and our biology in totality.
When we take Vit D orally, it seems like we short circuit this system entirely...we get the increase on our lab reports but the oral Vit D lacks the photons of the sun's energy. It's knocking but no one is actually there. It looks like Vit D, fits some of the receptors, but has little to none of the actual power of real sun driven Vit D.
And when we supplement, we stop ourselves from getting the real thing too because we break our negative feedback mechanism. Then we have the knock on effects to other vits...mainly A and K2 and calcium becomes dysregulated too.
It's just like empty calories...yes, those Doritos are technically "food" but they don't contain the power of real food like kale or good farm raised grass fed beef.
We have low D because we are disconnected from the light of the sun and spend too much time looking at artificial suns like our LED light bulbs, TVs, computers, tablets, phones, etc. Our bodies literally have no idea what time it is anymore and they do NOT like it. It's adding insult to injury to our chronically ill population that is then exacerbated when doctors start piling on the oral D supplements.

My real concern: They also suffer from a more serious subclinical problem. They can never reverse their leaky gut due to chronic inflammation from a subclinical infection. Often they see a short improvement with the pill but it lasts 6-8 weeks. The reason for both of these clinical features is that they likely have a co morbid lack of Vitamin A in the diet (especially in winter) to offset the raised supplemental Vitamin D3. This rarely happens in subtropical areas but happens more frequently at latitudes above Atlanta in winter in the US. Each cell in our body has 2 vitamin A receptors for every Vitamin D receptor. We also have VDR's in our gut. So as our vitamin D level rises because we take the supplement orally we give our gut VDR's a falsely elevated signal. This changes optical signaling in the GALT and its T cells. The cells sense the D3 chemical signal but the tissues do not have the photon energy or momentum. and therefore there is not enough UV photon power within the tissues. As a result of feedback loops our endogenous Vitamin A source is used up even quicker and an imbalance results. We need to make sure we are getting enough of the fat soluble Vitamin A too as Vitamin D3 goes up from pills. rarely does this get spoken about in people outside the subtropics in autumn or winter. These two vitamins are metabolically coupled but one is made from UVB light and the other is made by the photoperiod of the day. This is probably the most common reason people have persistent bloating and cannot clear H Pylori or Candida infections from their guts when they are not getting a full spectrum sun signal to support the D3 chemical. I've seen this develop in people when they transition to a meat laden paleo template while supplementing Vitamin D3. It is rare in an epi-paleo Rx because seafood and mushrooms have a lot flesh that contain enough of the photonic power embedded in the food stuff. We are designed to make D3 from sunlight and not a pill. So if you have IBS be aware of this unusual possibility of you live further from the equator.

Low vitamin D levels associated with IBS
People with IBS have been found to have low levels of vitamin D, and those who have taken a supplement have found that it helped to improve their condition.
