Antibacterial hand soap
This is the easiest swap on the list, and it comes straight from a regulator — no health claim from me required. In 2016 the FDA removed triclosan and 18 other active ingredients from consumer antibacterial soaps because manufacturers didn't show they were safe for long-term daily use or any better than plain soap and water.
Look for instead: a plain, plant-based hand soap. No "antibacterial" active ingredient needed.
How strong is the evidence? The firmest kind — a direct FDA regulatory action. I don't have to add a single claim of my own.
