I wish I could give you a simple answer. I started Resistant starch about 16 months ago. I started with the potato starch and then added several others. I am continually adding and changing the supplements that I take, so it is really difficult to attribute any improvements to any one specific action.
The best way for me to compare is to look back at the way I felt before I started the RS, and compare that to the way I feel now. I actually hit my low point back in 2008, and have been slowly improving ever since. Back then, I was very nearly bed bound, my blood pressure was down to 80/50, and I had severe headaches on a continuous basis. My fist big step was Valcyte which I took back in 2008. Since then I have tried methylation, LDN, and pretty much every supplement that I have heard about. I have stopped some due to ineffectiveness or cost, but have stuck with most of them.
I have made significant improvements to my health with these steps. Today, I watch a grandchild three days a week, have begun to spend considerable time with my hobbies, keep up with the chores around the house, and have much less headache pain. I still need to rest for a while after lunch, but don't necessarily sleep. This alone is a big change for me. I am clearly not at 100%, but at least I feel that I am heading in the right direction.
Just about every thing that has resulted in an improvement has been difficult to start, but has been worth it in the long run. I have had to start with minute quantities of LDN for example. Over time I slowly increased the dose until I am able to tolerate several milligrams a day. I did the same with LAG. The first dose was pretty nasty for me. I reduced the dose to a very tiny amount and slowly built it up over many weeks. The improvement has been small. but if you add up all the small improvements, the results are clearly worthwhile.
