I started taking high doses of Boswellia about two months ago (I take 1200 mg three times per day with meals) and my fatigue and digestive problems have cleared up almost completely. I am a convert! I looked around on the forum to find out if anyone else was doing this, but I couldn't find anything . . . so glad there are more of us!
I had been taking Boswellia for six or nine months at a lower dose (500 mg one time per day), but it didn't seem to do anything at all - my colonoscopy showed worsening inflammation. Everything changed for me (praise God!) when I re-read
the study that showed Boswellia being as effective as mesalamine (only without the side effects) - they used 1200 mg three times per day with meals. So I did the same and WOW! I feel truly transformed - I honestly didn't realize how sick I was until I started getting better. I noticed a difference overnight. I still don't eat my trigger foods (onions, coffee, watermelon, oatmeal, quinoa, and some others), and I still am gluten-free, but I am now a healthy person rather than a sick person. I also noticed that my joints don't hurt, my skin isn't as irritable (I got itchy rashes pretty regularly when I was sick), my mood is elevated (perky, even!), I want to have sex again finally, I HAVE to be active because I have energy! My dental hygienist told me Friday that she can tell I'm healthier just by looking at the state and color of my gums. Inflammation was causing problems all over my body and now it isn't. Boswellia has been an amazing miracle for me. Obviously, I can't say it will do that for everyone, but I do wish everyone would at least give it a try.
I also take L-Glutamine and turmeric/curcumin as per the same studies you found. I don't take any prescription medications except hormones to replace those I lost when my ovaries were removed (estrogen, testosterone) and thyroid hormone. I am working towards a plant-based diet with less sugar and refined foods. I don't seem to have trouble with most foods (other than my known triggers above) now that the inflammation is down.
