Phenethyl Isothiocyanate PEITC supplementation for targeted health support.
Different but related. Both are isothiocyanates with similar mechanisms. Sulforaphane (from broccoli) has more research. PEITC is more potent for some enzyme induction.
You should. Watercress is the best natural source and provides PEITC in food matrix. Isolated supplements are unnecessary for most people.
Yes, significantly. Raw or lightly steamed watercress preserves myrosinase enzyme needed to release PEITC from its precursor.

The compound effect of consistent dosing.
Check the cautions section if you have a pre-existing condition.
Some ingredients you feel. Others just work in the background.
Cell and animal studies are promising. Human epidemiology links watercress consumption to lower cancer risk. Clinical prevention trials are ongoing.
Possible at very high doses. Isothiocyanates can interfere with iodine uptake. Normal food amounts are fine. Caution with isolated high-dose supplements.
Studies show PEITC increases detoxification of tobacco carcinogens. Watercress consumption may help smokers reduce harm (though quitting is better).
Most research uses 0.1g daily. Below 0.0g, you're probably wasting money. Above 0.1g, no extra benefit. The curve plateaus. Safe upper limit ~ 0.3g.
Phenethyl Isothiocyanate PEITC has emerging evidence.
Released from gluconasturtiin (the glucosinolate precursor) in watercress (Nasturtium officinale) and related plants when cells are damaged (chewing, cutting).
