Beetroot has long stood in the shadow of more popular supplements – until sports science re-evaluated it. Today, beetroot extract is among the best-studied natural ergogenics of all.
The reason is simple: its natural nitrate content, which the body converts into nitric oxide, which in turn dilates blood vessels, improves muscle blood flow, and reduces the oxygen cost of performance.
Pulse Performance Beet Root Extract provides 600 mg of nitrates per serving from an extract standardized to 10% nitrates. Clean formula – 100% beetroot extract, nothing more.
How it works
The journey of nitrates from extract to muscles involves several steps, but the body handles it naturally and effectively.
After ingestion, nitrates (NO₃⁻) are absorbed into the blood. Bacteria in the oral cavity convert them into nitrites (NO₂⁻), which are then reduced to nitric oxide (NO) – a signaling molecule that plays a fundamental role in the vascular system.
Nitric oxide causes vasodilation – the relaxation of smooth muscle in blood vessels. The result is:
- better blood flow to working muscles
- more efficient transport of oxygen and nutrients
- lower oxygen consumption at the same intensity of performance
- delayed muscle fatigue
In practice, this means that under the same load, the body works more efficiently – and you get a better result for the same effort.

What science says
- Endurance performance.Nitrate supplementation consistently improves performance in time trials and extends time to exhaustion in endurance activities. The effect is strongest in recreational and performance athletes – results are less consistent in elite athletes, likely because their bodies are already adapted to higher blood flow.

- Explosiveness and interval training.Beetroot extract is not just for marathon runners. Studies confirm a positive effect on performance during short bursts of high intensity – sprinting, interval training, strength exercises. Nitrates improve the function of type II muscle fibers, which are key to explosive movement.

- Blood pressure.Nitric oxide has a proven effect on lowering blood pressure. A 2022 meta-analysis confirmed that beetroot nitrate supplementation reduces systolic and diastolic blood pressure in adults with arterial hypertension.

- Antioxidant protection.In addition to nitrates, beetroot also contains betalains – natural pigments with proven antioxidant and anti-inflammatory effects. These substances complement the effect of NO and contribute to the overall protection of cells against oxidative stress during physical exertion.

Why extract, not juice
Beetroot juice works – but it is bulky, contains sugars, and its nitrate content varies from batch to batch. A concentrated extract standardized to a precise percentage of nitrates solves all three problems at once.
Standardization to 10% nitrates means that each dose contains exactly 600 mg of nitrates – regardless of season, origin, or harvest method. No guessing, no variability.
Who is Beet Root Extract for
- Endurance athletes– runners, cyclists, swimmers, triathletes. More efficient oxygen use = better performance at the same load.
- Interval training and CrossFit– nitrates improve performance even during short bursts of high intensity, not just during long efforts.
- Strength athletes– better muscle blood flow improves the pump, nutrient delivery, and metabolite clearance.
- People with high blood pressure– natural vascular support without drugs. Consult your doctor if you are on medication.
- Anyone before a demanding workout– beetroot extract works as a natural "pre-workout" without stimulants, without caffeine, without a crash effect.
Things you might have wondered
’’Isn’t it enough to just eat beetroot?’’Yes and no. Beetroot is an excellent source of nitrates – but the nitrate content in fresh vegetables varies significantly depending on soil, fertilization, and storage. For a consistent and measurable effect before performance, a concentrated standardized extract is a more reliable choice than relying on vegetables with an unknown content.
’’How do I know it’s working?’’A classic telltale sign of beetroot supplementation is red-colored urine or stool – beeturia. It is a completely harmless effect caused by the pigment betanin, which the body simply excretes. About 10–14% of the population does not experience this phenomenon at all. It is neither an indicator of efficacy nor a problem.
’’Is it a pre-workout or more of a daily supplement?’’Both make sense – it depends on the goal. For an acute performance boost before a specific workout or race, a single dose 2–3 hours beforehand is enough. For long-term benefits for blood pressure and vascular health, daily use makes sense.
How to use
Dose:1 leveled scoop (6 g) mixed in 200 ml of water.
When:2–3 hours before performance – nitric oxide levels in the blood reach their peak in this window. When used daily, any time of day.
Tip:Avoid mouthwash containing antibacterial agents before and after consumption – bacteria in the mouth are an essential part of converting nitrates into nitrites. Antibacterial mouthwash disrupts this process.
Duration of supplementation:The product is designed for intensive training blocks – short-term and longer-term use are both safe.
