Overview

Olive Leaf Extract shows some potential for antioxidant and anti-inflammatory effects based on in vitro evidence and studies on animals. Some human trials suggest it may have cardio-metabolic benefits, but these results are not consistent, with many recent studies showing no effect. The product is standardized to a minimum of 6% oleuropein, but the optimal dosage for efficacy is unclear. Overall, claims of effectiveness should be interpreted cautiously due to the low quality of available research.

The Good

Standardized to 6% oleuropein, a primary bioactive compound.

Vegetarian/vegan friendly and free from common allergens.

The Bad

Limited research on long-term effects.

Some research indicates no benefit on primary outcome measures.

Potential for mild side effects such as stomachache and headache.

Is it for you?
