Blackcurrant Extract

What Does Blackcurrant Extract Do?

Blackcurrant extract is a potent source of anthocyanins, specifically delphinidin-3-glucoside and cyanidin-3-glucoside, which act as powerful antioxidants and vasodilators. These compounds work together to optimize your cardiovascular response to intense physical stress and improve overall performance.

• Nitric Oxide Support: It stimulates nitric oxide synthase (eNOS), leading to improved vasodilation and more pronounced muscle pumps during your workout.
• Enhanced Blood Flow: By relaxing the endothelial lining of blood vessels, it increases oxygen and nutrient delivery to working muscles, which can help you push through high-volume sets.
• Post-Workout Recovery: The high antioxidant content helps neutralize reactive oxygen species (ROS) produced during training, potentially reducing delayed onset muscle soreness (DOMS).
• Metabolic Efficiency: Research indicates it may enhance fat oxidation rates during exercise by improving peripheral circulation and metabolic flexibility.

Clinical vs. Gym Bro Dosing

Key Insight: Always look for the standardization on the label. A 200mg dose of an extract standardized to 25% anthocyanins is significantly more effective than 500mg of simple blackcurrant fruit powder, which lacks the concentrated active compounds needed for a real pump.

Side Effects & Warnings

• Gastrointestinal Distress: Some users may experience mild bloating or loose stools when taking high doses on an empty stomach.
• Blood Pressure Interaction: Because it promotes vasodilation, it may cause a slight drop in blood pressure, which could lead to lightheadedness in those already prone to hypotension.

Contraindications: If you are currently taking anticoagulant or antiplatelet medications, speak with a doctor before use, as blackcurrant extract may further increase blood flow and potentially slow clotting.
