One of the strongest evidence bases in all of nutritional science — backed by meta-analyses and systematic reviews
If there's one juice ingredient with undeniable clinical evidence, it's beetroot. The research on beetroot is so strong that it's used in clinical nutrition protocols and sports science programs worldwide.
The mechanism is well-understood: beetroot is exceptionally rich in dietary nitrates. When you consume beetroot juice, bacteria on your tongue convert nitrates to nitrites, which are then converted to nitric oxide (NO) in your body. Nitric oxide is a critical signaling molecule that dilates blood vessels, improving blood flow and reducing blood pressure.
Blood Pressure: A 2008 study published in Hypertension found that dietary nitrate from beetroot juice significantly reduced blood pressure within 3 hours of consumption, with effects lasting up to 24 hours. A subsequent meta-analysis published in the Journal of Nutrition, analyzing multiple clinical trials, confirmed that beetroot juice supplementation reduces systolic blood pressure by an average of 4.4 mmHg. To put that in perspective — a 4.4 mmHg reduction in systolic blood pressure is associated with approximately 10% reduction in cardiovascular mortality at a population level.
Athletic Performance: A systematic review in Nutrients found that beetroot juice supplementation improved cardiorespiratory endurance in athletes by increasing efficiency, improving performance at anaerobic threshold, and increasing time to exhaustion. This is why beetroot juice has become a staple supplement in professional sports nutrition.
Skin Benefits: Beetroot's betalains (the pigments responsible for its deep red-purple color) are potent antioxidants. A review in Phytomedicine found betalains eliminate oxidative and nitrative stress by scavenging free radicals and preventing DNA damage. The combination of antioxidant protection and improved blood flow (more oxygen and nutrients to skin cells) contributes to healthier, more radiant skin — which is why beetroot is a key ingredient in our Skin Glow shot.

Research shows effects within 3 hours of consumption, peaking at 6-8 hours and lasting up to 24 hours (Webb et al., 2008).
Yes, this is called beeturia and is completely harmless. About 10-14% of people experience it. It's just the betalain pigments passing through your system.
