In strength training practice, athletes and recreational trainers often wonder whether it is better to drink beetroot juice (a source of nitrates) or take creatine before training. Both preparations have their own mechanisms of action and can affect exercise capacity, performance, and key physiological responses, but their short-term effects differ significantly.
How do nitrates in beet juice work?
Beetroot juice provides nitrates (NO3−), which are partially converted into nitric oxide (NO) in the body. NO dilates blood vessels, can improve muscle perfusion, increase mitochondrial efficiency, and reduce the oxygen cost of muscle work. This effect occurs relatively quickly—usually 2–3 hours after consumption—and lasts for several hours.
How does creatine work?
Creatine increases phosphocreatine stores in muscles, which accelerates ATP resynthesis during short-term, intense, and repetitive efforts. The standard method of use is a loading phase (e.g., 20 g/day for 5–7 days) or a maintenance dose of 3–5 g/day. For this reason, the full benefits of creatine are usually observed after several days to weeks of use. The effects include greater strength and maximum power, improved ability to perform repetitions with heavy loads, and faster recovery between sets.
Which works faster: beetroot or creatine?
Beetroot juice works faster. You will feel the effect within a few hours after consumption. Nitrates affect blood flow and exercise tolerance. You will notice this during training. Creatine needs time to saturate the muscles. Therefore, a single dose will not be effective if you have not used creatine before.
Impact on performance and physiological parameters
- Beet juice: improved aerobic capacity, reduced oxygen cost at subthreshold loads, better muscle perfusion, and possible improvement in the number of repetitions in moderate-intensity sets.
- Creatine: increased power and strength during short, maximum efforts, higher number of repetitions with heavy weights after muscle saturation, improved recovery between sets.
When to use a given supplement?
Choose a supplement depending on your goal and timing. Beet juice is good when you need a quick effect before training. Drink it 2-3 hours beforehand. Creatine is better if you want to increase strength and power in the long term. Remember that it takes time to saturate the muscles.
Sample practical protocols
- Beetroot juice (acute): 300-500 ml of natural beetroot juice or an equivalent dose of nitrates (~6-8 mmol) 2-3 hours before training.
- Creatine (rapid saturation): 20 g/day divided into 4 doses for 5–7 days, then 3–5 g/day as a maintenance dose (historical method, no scientific basis for its use)
- Creatine (continuous use): 3–5 g/day without a saturation phase — effects will appear after 2–4 weeks.
- Combination: use creatine daily for long-term gains, and drink beet juice before selected workouts for an immediate performance boost.
Common mistakes and what to avoid
- Expecting beet juice to replace weeks of creatine supplementation in terms of maximum strength.
- Lack of consistency: creatine works after muscle saturation – sporadic doses will not be effective.
- Using poorly researched supplements or products with unknown nitrate/creatine content.
- Neglecting your diet: both supplements work best with a well-balanced protein and energy intake.
Safety and contraindications
Creatine is widely considered safe for healthy individuals, but if you have kidney disease or are taking medication, you should consult your doctor about supplementation. Beet juice is generally safe, but people taking blood pressure medication or nitrates for heart conditions should exercise caution. If you have any health concerns, talk to your doctor or dietitian before starting supplementation.
| Feature | Beet juice | Creatine |
|---|---|---|
| Mechanism | Increases NO → better perfusion, lower oxygen cost | More phosphocreatine → faster ATP resynthesis |
| Duration | 2–3 hours after consumption (acute) | Days/weeks needed for saturation; immediate effect after saturation |
| Best use | Improvement of performance and repeatability of efforts in the short term | Increased strength and power, better results in strength training in the long term |
| Sample dose | 300–500 ml of juice (6–8 mmol of nitrates) | 20 g/day (saturation) → 3–5 g/day (maintenance) |
FAQ
Will beet juice improve my maximum 1RM?
There is little evidence that beet juice directly increases 1RM. It works better for repetitive efforts and endurance elements of training.
Can I take creatine only before training?
A single dose before training without prior muscle saturation does not produce predictable results. It is better to take creatine regularly to keep your muscles saturated.
Can beet juice and creatine be used at the same time?
Yes, they complement each other: creatine builds energy reserves in the long term, while beet juice provides immediate improvement in perfusion and performance.
Are there any side effects of beet juice?
Sensitive individuals may experience mild stomach upset and discoloration of urine (known as bakuria). If in doubt, consult a specialist.

Define your goal: rapid improvement in performance (beet juice) or long-term increase in strength and power (creatine)? Choose a strategy that fits your training plan and goals.
Test the protocol: drink 300-400 ml of beet juice 2-3 hours before a heavy workout and see if you can do more reps or if you feel better. You can also start taking 3-5 g of creatine per day to steadily build strength.
