Blackcurrant Visual Performance Randomized TrialThis systematic review aimed to evaluate randomized controlled trial (RCT) evidence on the effects of carotenoids, anthocyanins, polyunsaturated fatty acids, and combined nutraceutical formulations on refractive outcomes, axial length, macular pigment optical density (MPOD), visual function, and symptoms of visual fatigue.1Martinez-Perez C (2025)Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials.
Blackcurrant Visual Performance Randomized TrialEligible studies were RCTs involving individuals with myopia or at risk of myopia, comparing nutritional supplementation with placebo or active controls.1Martinez-Perez C (2025)Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials.
Blackcurrant Visual Performance Randomized TrialTwo reviewers independently screened studies, extracted data, and assessed risk of bias using the Cochrane RoB 2 tool.1Martinez-Perez C (2025)Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials.
Blackcurrant Visual Performance Randomized TrialBackground/objectives Nutritional supplementation has been proposed as a potential adjunct strategy in myopia prevention and control through antioxidative, anti-inflammatory, and extracellular matrix-regulating mechanisms.1Martinez-Perez C (2025)Nutritional Supplementation for Myopia Prevention and Control: A Systematic Review of Randomized Controlled Trials.
Blackcurrant Visual Performance Randomized TrialPurpose Despite equivocal human study data, anthocyanin-rich blueberries are associated with positive glycaemic effects which could benefit satiety and other cardiometabolic outcomes.2Ellis LR (2026)A randomised, double-blind, placebo-controlled trial to assess the postprandial dose-dependent effects of wild blueberries on metabolic and cognitive outcomes following a high-carbohydrate breakfast.
Blackcurrant Visual Performance Randomized TrialConclusion Wild blueberry effects on postprandial glucose and appetite hormone responses were evident at anthocyanin doses of 300 mg and above but did not impact other outcomes in healthy adults.2Ellis LR (2026)A randomised, double-blind, placebo-controlled trial to assess the postprandial dose-dependent effects of wild blueberries on metabolic and cognitive outcomes following a high-carbohydrate breakfast.
Blackcurrant Visual Performance Randomized TrialThe objective of this study was to examine the dose-dependent effects of freeze-dried wild blueberries on postprandial glucose response simultaneously with changes in satiety, blood pressure and cognitive function.2Ellis LR (2026)A randomised, double-blind, placebo-controlled trial to assess the postprandial dose-dependent effects of wild blueberries on metabolic and cognitive outcomes following a high-carbohydrate breakfast.
