Buying Guide

Check oleuropein concentration

Oleuropein is the primary active compound in olive leaf; compare percent or mg per serving to match desired potency

Choose the delivery form

Capsules, liquids, and combined leaf/fruit extracts offer different dosing flexibility and absorption profiles for your routine

Match dietary preferences

Look for vegan, vegetarian, organic, or non-GMO labels if those attributes matter for your regimen

Consider added actives

Some formulas include hydroxytyrosol, berberine, or other botanicals which target metabolic, heart, or immune support differently

Verify sourcing and extract standards

Products that list Spain-grown olives or percent polyphenols/oleuropein give clearer expectations of raw-material quality
