Why these metrics matter
Active amount
Compare the actual active amount per serving before comparing brands.
Form
Form changes absorption, tolerance, dose practicality, and safety context.
Label clarity
Blends can hide whether the relevant ingredient is present at a useful amount.
Safety
Medication, pregnancy, condition, allergy, and high-dose context should be checked first.
