Eye Health & Antioxidant
To evaluate MaquiBright (maqui berry extract) effects on dry eye symptoms.
Study Type
Randomised, double-blind, placebo-controlled
Purpose
To evaluate MaquiBright (maqui berry extract) effects on dry eye symptoms.
Dose
Maqui berry extract 60mg standardised to delphinidins daily
Participants
40 adults with dry eye symptoms
Duration
8 weeks
Results
Maqui berry extract significantly increased tear secretion volume and improved tear film stability. OSDI symptom scores significantly improved. Delphinidins confirmed as key active compounds.
How They Measured It
