The adverse effects of taurine on our microbiome and hydrogen sulfide production may be ameliorated by diets high in fiber and low in saturated fats.
That was a lot, I know, so let me try to break it down a bit. Taurine is turned into the “rotten egg” gas hydrogen sulfide. (You’ll smell it coming out of your rear should you decide to try it.) It doesn’t just stink, but it does damage DNA. However, the byproducts of fiber metabolism can counteract the damaged caused by hydrogen sulfide. That’s where a high-fiber diet comes in, so eat lots of legumes and whole grains. Then there’s the saturated fat that promotes the growth of the bad bacteria that generate hydrogen sulfide and more of the cancer-promoting secondary bile acids. So, just as you should not be doping with beet juice or nitrate supplements unless you’re eating plant-based, you probably shouldn’t supplement with taurine unless you’re on a plant-predominant diet. In fact, it might not be a good idea to supplement with taurine at all—unless the benefits seen in rodents and monkeys translate to humans, possibly making it a great idea. Recently, new research questioned a fundamental pillar of the taurine anti-aging narrative: Taurine levels don’t (pubmed.ncbi.nlm.nih.gov/40472098/) appear to decrease with age after all, challenging (pubmed.ncbi.nlm.nih.gov/40481202/) the underlying logic of supplementation.
