Sorry, I don't know of any single supplements that combine the ones I mentioned but I'm sure there are some. I take some of them but I buy them individually because I'm so sensitive to most supplements.
Results should be pretty quick, I'd say within a week. But many of us are sensitive to supplements and get adverse reactions. So we have to start with very low doses and slowly work our way up, to avoid this.
Yes, as I mentioned above. Glutathione is a very powerful supplement and can be very helpful for liver detoxing and general inflammation. But, because it's so powerful it can cause detox symptoms.
