Pure Blue - Organic Blueberry Capsules (120 pcs)

Scientifically Supported Health Benefits

1. Cognitive Performance and Neuroprotection

Blueberry polyphenols cross the blood-brain barrier and reduce neuroinflammation. Clinical trials in older adults have shown improvements in memory, executive function, and mood after daily blueberry or juice intake. Blueberries also promote neuronal signaling and synaptic plasticity [3,4].

2. Cardiovascular and Circulatory Health

Blueberries improve endothelial function, reduce arterial stiffness, and lower blood pressure. A meta-analysis of randomized trials found blueberry supplementation significantly reduced systolic blood pressure and LDL cholesterol levels [5].

3. Vision and Eye Health

Anthocyanins in blueberries improve retinal circulation and protect against oxidative damage in photoreceptor cells. They may reduce eye fatigue, enhance night vision, and delay progression of age-related macular degeneration [6].

4. Anti-inflammatory and Antioxidant Defense

Blueberry juice increases endogenous antioxidant enzyme levels (SOD, CAT) and reduces markers like CRP and TNF-α. It helps combat systemic inflammation and supports immune resilience [1,7].

5. Glucose and Metabolic Regulation

Blueberries improve insulin sensitivity and modulate glucose transporters. In individuals with metabolic syndrome or prediabetes, blueberry juice reduced fasting glucose, HbA1c, and post-meal glycemic response [8].

6. Gut Microbiota and Digestive Support

Blueberry polyphenols act as prebiotics and support the growth of beneficial gut bacteria (Bifidobacterium, Akkermansia). This enhances short-chain fatty acid production and intestinal barrier integrity [9].
