For a measurable boost in power and endurance, the best time to drink beetroot juice is 2 to 3 hours before exercise. This isn't an assumption. It's the precise window where blood nitrite levels peak, according to research in the Journal of Applied Physiology.
Whether you're chasing a personal best or supporting healthy blood pressure, timing is the single most important variable. This guide breaks down the science, the protocols, and the one mistake that can nullify your results.
The 2 to 3 Hour Golden Window
Beetroot doesn't work like caffeine. It requires a multi-stage conversion process before your body can use it.
Dietary Nitrate (NO₃⁻) → Oral Bacteria Convert to Nitrite (NO₂⁻) → Nitric Oxide (NO) Production → Vasodilation → ↑ Oxygen Delivery to Muscles
Plasma nitrite levels peak between 2 and 3 hours post-ingestion. Starting your workout inside this window ensures your blood vessels are fully dilated and oxygen delivery is maximised.
The research is consistent. Bailey et al. (2009) found that dietary nitrate reduced the oxygen cost of exercise and extended time-to-exhaustion by up to 16% — but only when timed correctly. Peak plasma nitrite occurs 2–3 hours after consumption.
Why not earlier? The conversion isn't instant. Your body needs time to process the compounds.
Why not later? You'd miss the peak window. Your muscles would start the session without full oxygen efficiency.

The Absorption Timeline
Here is exactly what happens after you take Stamox:
| Time After Taking | What Happens |
| 0–30 min | Compounds enter the stomach. Absorption begins. |
| 1 hour | Nitric oxide levels start rising. Blood vessels begin to relax. |
| 2–3 hours | Peak vasodilation. Peak oxygen delivery. This is your window. |
| 4–6 hours | Effect gradually declines. |
The window is narrow. Miss it, and you leave most of the benefit on the table.
What Athletes Measure
Timing isn't theoretical. Athletes measure it. Here's what they report when they get it right:
"380 watts at 145 bpm with Stamox. Without: 153 bpm. That's 8 beats lower at the same power."
— Arvid Johannesen, Norwegian & Nordic Champion Cyclist
"166 bpm on 3:03/km reps. The data doesn't lie."
— Connor Rogers, Runner, 5K 14:27 · 10K 30:29
"The predictable effect — peak performance 2–3 hours after taking it — lets me plan every session with precision."
— Maciek Maślanko, Polish Champion & World Championship Medalist
"My heart rate is 5 to 6 bpm lower at the same pace with Stamox. Same intensity, less strain."
— Maicol Petta, Ironman Italy AG Champion
These results depend on one thing: taking it at the right time.
The 4 Ways to Time Your Intake
1. The Morning Ritual
Best for: Blood pressure support and all-day vitality.
Mix ½ to 1 tablespoon of Stamox into water first thing in the morning. Continuous, low-dose nitric oxide production relaxes arterial walls and increases cerebral oxygen delivery — without the jitters or crash of caffeine.
| What It Does | How It Works |
| Supports healthy blood pressure | Nitric oxide relaxes and widens blood vessels |
| Provides steady energy | Clean, stimulant-free vitality throughout the day |
| Sharpens mental clarity | Increased cerebral blood flow to the brain |
| No caffeine crash | Nitrates work without stimulating the central nervous system |
Smoothie Recipe: Mix 1 tablespoon of Stamox, frozen banana, frozen berries (add anything extra you like).
Yoghurt Endurance Bowl Recipe: Mix 1 tablespoon of Stamox, Greek yoghurt (add berries, fruit, granola).
2. The Pre-Workout Window
Best for: Athletic performance, power output, and VO₂ max optimisation.
| Timing | Action |
| 2–3 hours before exercise | 1 tbsp of Stamox mixed with 300ml water |
| During efforts over 90 minutes | 1 additional tbsp mid-session |
This timing allows peak vasodilation to coincide with the highest intensity of your workout. The result: your mitochondria produce more ATP using less oxygen. You hold a higher pace or power output at a lower heart rate.
What to expect:
- Lower perceived effort — your target pace feels easier
- Sustained power output — more watts at the same heart rate
- Improved oxygen efficiency — muscles conserve glycogen
One critical rule: Avoid antibacterial mouthwash for at least 2 hours after taking Stamox. The oral bacteria required to convert nitrate into nitrite are essential. Kill them, and you lose the performance benefit.
3. Post-Workout Recovery
Best for: Reducing muscle soreness and accelerating repair.
Take 1 tablespoon of Stamox within 30–60 minutes after a hard session.
Beetroot contains betalains — nitrogen-rich pigments with anti-inflammatory properties. These compounds are highly sensitive to heat and pasteurisation. Stamox's cold-processed extraction preserves them, supporting faster recovery between sessions.
4. The Loading Phase for Competition
Best for: Maximising tissue saturation before an A-race or intense training block.
| Phase | Duration | Protocol |
| Pre-event loading | 5–7 days before race day | 1–2 tbsp daily |
| Race day | 2–3 hours before start | 2–3 tbsp |
Daily loading saturates muscle tissue with the full beetroot matrix, creating a reservoir of performance potential. This chronic strategy is more effective than a single pre-race dose.
"My loading protocol before racing this season was 2–3 tablespoons of Stamox 3–7 days before racing. I used it when winning AG Ironman South Africa."
— Gilberto Neirotti, IRONMAN & Finalist Masterchef Italia
The 5 Most Common Mistakes
1. Taking it 30 minutes before training.
You're starting your session before the compounds peak. You're leaving most of the benefit on the table.
2. Using mouthwash after taking it.
Mouthwash kills the oral bacteria that convert nitrate into nitrite. Skip it for at least 2 hours.
3. Taking it with hot liquid.
Use cold or room temperature water. Heat degrades some of the beneficial compounds.
4. Taking generic beetroot powder.
Active compound content varies widely between brands and batches. One scoop might work. The next might not. Stamox is measurable and consistent per scoop — the full whole-root matrix in every dose.
5. Only taking it on race day.
The biggest adaptations — VO₂ max improvements, mitochondrial efficiency — come from consistent use over 4–12 weeks.
Summary
| Your Goal | Best Time | Dosage |
| Blood Pressure & Vitality | Morning | ½–1 tbsp daily |
| Athletic Performance | 2–3 hours pre-workout | 1–2 tbsp |
| Post-Workout Recovery | Within 30–60 min after | 1 tbsp |
| Competition Loading | Daily for 5–7 days before | 2–3 tbsp daily |
| Mid-Session Top-Up | Every 2–3 hours during long efforts | 1 tbsp |
Can I just drink regular beetroot juice?
You would have to drink a lot of "regular" beetroot juice to achieve a good effect, and the amount you need to drink will vary enormously.
There are many types of beetroot juice available for purchase. But the "strength" of these is not further described, defined and tested. You can use beetroot or beetroot juice, but the effect will be unpredictable and usually less effective, or have zero effect. It is simply not possible to create a predictable training program with regular beetroot juice.
When should I drink Stamox beetroot juice?
Timing is critical for maximum effect. Nitric oxide levels peak 2-3 hours after consumption.
STANDARD TRAINING DOSE
1-2 tablespoons mixed with water. Take 2-3 hours before your session.
COMPETITION / RACE DAY
2-3 tablespoons. For endurance events (more than 1 hour), take an additional 1 tablespoon closer to start time.
LOADING PHASE (3-7 days before key event)
Take competition dose daily for 3-7 days leading up to maximize nitrate stores and performance.
DAILY HEALTH DOSE
1 teaspoon to 1 tablespoon daily. Supports circulation, energy, and antioxidant defense.
Mixing Instructions:
• Add powder to water. Let sit 2-3 minutes. Stir.
• For smoothest texture, use a frother or blender.
• Can be added to smoothies, yogurt, or oatmeal.
PRO TIP:
Mix with citrus: Lemon or lime improves taste and absorption. Vitamin C keeps nitric oxide active longer — research confirms the combo works better than beetroot alone.
Skip mouthwash after Stamox.
Mouthwash kills the oral bacteria that make nitric oxide. Research shows up to a 12% drop in vascular function. Brush? Fine. Mouthwash? Wait 6 hours.
What does Stamox taste like?
Stamox has a slightly sweet and earthy flavour, just as nature intended it to be. There are no added flavours or sweeteners.
It has a versatile flavour that can be mixed with water, citrus (will hide the beetroot taste), yoghourt, oats, smoothies, in electrolytes, carb drink, etc.
"I've used beetroot powder from another supplement company before but Stamox is significantly better as it is has better solubility and lighter taste and consistency. The other company's product is heavier in texture and taste and also harder to digest. In fact, they contain a higher fiber content (which is harmful pre-workout)." Says Italian cyclist Marco Valerio Ciminelli
Why do I need to avoid mouthwash?
This is a critical biological step. The "Nitrate-Nitrite-NO" pathway relies on commensal bacteria on the back of your tongue to convert nitrate into nitrite. Antibacterial mouthwash kills these bacteria, effectively "breaking" the chain and preventing the performance benefits.
