Forms Comparison

FormBioavailabilityBest For
Chromium PicolinateHighMost studied form for blood sugar and body composition — best overall choice
Chromium Polynicotinate (ChromeMate)Moderate-HighNiacin-bound chromium with good absorption — some prefer for lipid support
Chromium GTF (Glucose Tolerance Factor)ModerateDerived from yeast, contains the natural chromium complex — variable composition
Chromium ChlorideLowInorganic form used in some research — poorly absorbed compared to organic forms
