You certainly can lay off the pills and get retested and see if your numbers improve. I think there is some concern about the large dose D3 pills and liver, but if you are taking D3, I assume it is OTC, and so then I also assume it is likely a lowish dose. Although, you can buy 10,000 IU pills in the drug store, I used to take them. I completely disagree with the dosage suggested by @gailcalled, for a significant percentage of the population that isn’t anywhere near enough, almost all doctors recommend at least 2,000 IU daily if a patient is low in D, and I am going to assume you actually know you are low in D and not just popping the pills. For some indivuals it is possible that one pill too many of anything can be just too much for their liver, so you need to figure out what might be harming yours. Hopefully, it just resolves on its own.
Once you stop the possible culprits, and if your liver enzymes improve, then you can reintroduce one at a time and get tested again and narrow down possibilities. That is if your doctor thinks that is a reasonable idea. You have to partner with him, because you have to get the blood tests, you can’t guess.
Some of the most obvious commonplace things that cause liver damage in many people are Tylenol and drinking alcohol. The drug Diflucan also is a culprit, and that is taken by many women at one time or another. I assume your doctor asked you what medications you have taken recently and if you drink.
I have no idea about the green superfood you mentioned. What’s in it? What are the nutritional values on the package? Keep in kind the stated nutritional values can be way off on vitamins and minerals, they aren’t really regulated like pharmaceuticals.
