Most bergamot supplements use the peel oil, or a “citrus blend.” That's the cheap part of the plant, the same oil that goes into perfume and Earl Grey tea. It also carries bergamottin, the compound that makes grapefruit dangerous with heart and blood pressure medications. These bottles are unverified, underdosed, and the label almost never tells you how much of the real compound is inside.
Teravia uses 100% real Citrus bergamia fruit from Calabria, Italy. It's standardized to 50% polyphenols, with the number printed on the label, and tested by an outside lab. You get the actual compounds your liver needs, safe for daily use, long term. That's why it supports healthy cholesterol instead of just smelling like bergamot.
