Ingredient and preparation
Olive-leaf products may list Olea europaea leaf and sometimes an oleuropein amount, but extraction and standardisation vary.
Sources: National Library of Medicine, PubMed
Evidence and limits
The 2024 review included 12 short adult RCTs. Results across glucose, blood pressure, lipids and inflammatory markers were mixed, and the authors called for more consistent human trials; it is not a substitute for blood-pressure or glucose care.
Sources: National Library of Medicine, PubMed
Safety and a useful record
Discuss medicine context, especially where blood pressure or glucose medicines are involved, before treating a botanical extract as routine self-care.
