Olive Leaf Herbal Supplements

Olive leaf extract is a concentrated supplement made from the leaves of the olive tree, standardized for compounds like oleuropein; it is commonly taken to support immune function, antioxidant protection, and cardiovascular wellness based on traditional use and some clinical studies

Choose products standardized for active compounds (for example, oleuropein percentage) and follow manufacturer dosing; typical adult doses range from 500 mg to 1,000 mg daily of extract or as directed by a healthcare provider, who can adjust for age, weight, and health conditions

Olive leaf supplements come as capsules, tablets, liquid extracts/tinctures, and powders; bioavailability and convenience vary by form—capsules and tablets offer measured dosing and longer shelf life, while tinctures allow flexible dosing but may require more careful storage

Olive leaf is generally well tolerated but can lower blood pressure and blood sugar, so consult a healthcare provider if you take antihypertensive or diabetes medications; also check for allergy risks, pregnancy or breastfeeding contraindications, and potential interactions with blood thinners

Look for third-party testing or certificates of analysis, clear labeling of active compound concentrations (e.g., oleuropein), GMP manufacturing statements, and short ingredient lists without unnecessary fillers or artificial additives

Prices vary by concentration, brand, and form; expect budget options under $25 and mainstream quality supplements commonly in the $25–$75 range, with higher-cost specialized formulas above that

Store in a cool, dry place away from direct sunlight and moisture; follow the product expiration or best-by date—most sealed supplements remain stable for 1–3 years, but liquids and tinctures may have shorter shelf lives once opened
