Five things you can do today
Most people with IBD who pick this up want to do something right now. Here are the five supplements I believe in most, each with the exact product and a link. Take these actions, then come back for the why, the evidence, and the other ninety-five.
The order matters: medical team first, then a diet and lifestyle strategy, then supplements and herbs. "Please read this first" says why. Get the foundation in place, then add these five, one at a time.

Curcumin
The most-studied anti-inflammatory plant compound in IBD, with trials in both UC and Crohn's. If you can only afford one thing here, this is it.

Quercetin
Calms mast cells and histamine reactions. Thin human IBD data, strong biology, and the one I've watched help the most people over a decade.

Omega-3 EPA/DHA
Fish oil in the triglyceride form. Mixed trial record, but the UC trial that measured calprotectin was positive.

Bovine immunoglobulins (SBI)
Antibodies that bind bacterial toxins in the gut before they reach the wall. Dairy-free. Strong case series in refractory IBD.

Vitamin D3
Low in most people with IBD; pooled Crohn's trials show fewer relapses. A cheap blood test tells you the right amount. Standalone D3.
Buy on FullscriptHow to start them
One at a time, ten to fourteen days apart, on a diet and a medical plan your team already knows about, so you can tell what each one is doing.
Track four things on paper: stools, energy, pain, sleep. Test vitamin D before you start and again after three months; the right amount is a lab value, not a guess.
The full three-page entry for each of these begins in Section A, with the trials, the doses as studied, and my notes.
