Peppermint is clinically shown to enhance respiratory function by relaxing bronchial smooth muscles and increasing airflow, making it easier to breathe during intense training. It supports oxygen intake and CO₂ clearance, which improves VO₂ max and aerobic capacity. By promoting efficient breathing patterns, it helps reduce perceived effort, delays fatigue, and improves pacing—especially in endurance and high-output workouts. Perfect for athletes who want to stay composed, powerful, and in rhythm under pressure.

Arjuna Bark—known as the “Heart Bark”—is the hero ingredient in both Flow and Flow Pro. It’s the only herb clinically known to improve stroke volume (the amount of blood pumped per heartbeat), helping boost VO₂ max, endurance, and cardiac efficiency. Used for centuries in Ayurvedic medicine, Arjuna strengthens heart function and circulation without spiking heart rate or blood pressure. It’s also proven to reduce markers of cardiac fatigue, supporting faster recovery between intense training efforts. Think of it as heart armor—built for the unstoppable.

Beetroot is a natural nitric oxide booster that improves oxygen delivery by dilating blood vessels, enhancing blood flow, and reducing the oxygen cost of exercise. Studies show it can significantly increase VO₂ max, delay time to exhaustion, and improve work capacity—especially in endurance-based training. It also supports recovery by reducing inflammation and oxidative stress. Perfect for athletes looking to breathe easier, push longer, and recover faster.

Cayenne activates thermogenesis and improves blood circulation, helping shuttle oxygen and nutrients more efficiently during intense training. It supports cardiovascular function and metabolism, enhancing time to exhaustion and total work output. Cayenne’s natural capsaicin content helps reduce inflammation and muscle soreness, accelerating recovery between sessions. It’s the engine heat that helps your body run cleaner and harder—without the crash.

Ashwagandha is a powerful adaptogen that helps regulate cortisol, reduce fatigue, and enhance aerobic performance. When paired with Arjuna, studies show it can significantly increase VO₂ max and improve time to exhaustion. It supports hormonal balance, stress resilience, and post-exercise recovery—allowing athletes to maintain steady output even under intense training loads. Together, these effects make Ashwagandha a cornerstone for building long-term stamina, strength, and consistency.
