Frequently asked questions.
Nitric Oxide (NO) is a vital molecule naturally produced in our body that enables "cellular communication". Its primary task is vasodilation, i.e., widening of blood vessels.
Beetroot in our formula contains high levels of natural Nitrate (NO₃). When ingested, these nitrates convert first to Nitrite (NO₂) and then to Nitric Oxide (NO) in the bloodstream, optimizing blood flow.
Nitric Oxide Conversion Pathway
SourceBeetrootNO₃ (Nitrate)
▼
Step 1SalivaryNO₂ (Nitrite)
▼
Step 2Blood StreamNO (Nitric Oxide)
▼
ResultVasodilationIncreased Blood Flow
Result: More oxygen, more nutrients, and higher performance for muscles and brain.
Beetroot is nature's richest and most bioavailable source of nitrates. Unlike synthetic "Pre-workout" products, beetroot supports the body's natural production mechanisms.
Natural Absorption
Recognized and processed by the body with zero risk of side effects.
Antioxidant Support
Contains betalains providing cellular protection in addition to nitrates.
This formula is not just for professional athletes, but for anyone looking to optimize their circulatory system:
- Athletes: To increase stamina and maximize the "pump" effect.
- Active Professionals: To support cognitive focus by increasing oxygen delivery to the brain.
- Circulation Seekers: For those wishing to naturally balance blood flow and pressure.
Nitric oxide levels in the blood peak 45-60 minutes after consumption. Therefore, taking it about an hour before workouts or intense mental activity provides maximum efficiency.
Being 100% natural, it has no known harmful side effects. However, due to beetroot's natural pigments (betalain), a pinkish/reddish discoloration in urine or stool (Beeturia) may occur.
This is completely harmless and is proof of the natural, high-concentration beetroot content. You can balance this by increasing your water intake.
Pure beetroot extract has a characteristic "earthy" taste. However, our formula is optimized with natural flavors to balance the taste and make it enjoyable to drink, with no artificial sweetness.
