Blackberry extract is a concentrated fruit preparation standardized for higher anthocyanins and polyphenols. These compounds neutralize free radicals in the body.
Many people take blackberry extract for immune health and cardiovascular function. Evidence for heart-specific benefits is still emerging. Take it in capsule or powdered form, ideally with a meal to help digestion.
Because of its polyphenol content, blackberry extract might slightly thin the blood. This could interact with anticoagulant medications. Check with a healthcare provider before use if you are pregnant, breastfeeding, or scheduled for surgery.
