How Much Beetroot Juice Per Day For Athletes? | Best Intake

Most athletes use 70 to 140 mL of concentrated beet juice, or about 250 to 500 mL of regular juice, to get 6 to 8 mmol of nitrate.

Beetroot juice is popular with runners, cyclists, rowers, team-sport players, and lifters for one plain reason: it can make hard work feel a bit cheaper. The part that matters is nitrate. Your body turns nitrate into nitric oxide, which can help blood flow, muscle contraction, and the oxygen cost of exercise.

For most athletes, the sweet spot is not “drink as much as you can.” It is a measured dose that gives enough nitrate to matter, timed well before training or race start. That dose is usually 6 to 8 mmol of nitrate, which lines up with about 350 to 500 mg nitrate from a tested product.

If you want the short version in plain English, here it is: one concentrated shot is often enough, two shots are sometimes used for a loading plan, and random homemade beet juice is hit or miss because nitrate levels can swing a lot from batch to batch.

Beetroot Juice For Athletes: The Dose That Usually Works

The dose most often used in sports nutrition is 6 to 8 mmol of nitrate taken 2 to 3 hours before exercise. That usually means one 70 mL concentrated shot or a larger serving of standard beet juice. The Australian Institute of Sport nitrate guidance places that range right in the middle of current practice for performance use.

In food terms, that works out to this:

• Concentrated beetroot shot: about 70 mL for roughly 6 to 8 mmol nitrate in many sports products.
• Regular beetroot juice: about 250 to 500 mL, depending on how much nitrate the product contains.
• Powders and mixes: only useful if the label gives the nitrate amount, not just the beetroot weight.

That last point trips people up. “5000 mg beetroot powder” sounds hefty, but the useful number is the nitrate dose, not the beetroot headline on the front of the tub.

When Athletes Should Drink It

Timing matters. Nitrate needs time to move through the mouth-gut-blood route before exercise. Most studies and sports practice place the best window at about 2 to 3 hours before the session. The National Institutes of Health notes that many studies use beetroot juice once about 2.5 to 3 hours before exercise, or daily for a few days before an event, with typical nitrate intake around 5 to 11 mmol depending on the product, as outlined in the NIH exercise performance fact sheet.

That gives you two main ways to use it:

1. Single-dose plan: Take one serving 2 to 3 hours before a race, hard tempo, time trial, or repeated-sprint session.
2. Loading plan: Take the daily dose for 3 to 6 days before the event, then add the final pre-event serving on race day.

A loading plan is common when the target event is a big one and you want a steady routine rather than a one-off test. For many athletes, that means one shot per day in the lead-up, then one more shot before the start. Some race plans use more than that, but bigger intakes do not always beat the standard dose.

Who Tends To Get The Most From Beet Juice

Beetroot juice does not hit every athlete the same way. The best responses tend to show up in efforts that last about 4 to 30 minutes, along with some intermittent high-intensity work. That includes events such as a 5K run, a hard rowing piece, track cycling, or repeated hard bursts in field sports.

Recreational and well-trained athletes often get more from it than elite endurance athletes. At the top end, gains can be smaller or absent. That does not mean beet juice is useless for elite sport. It means expectations should stay grounded. A small edge can still matter, but it is not magic.

Team-sport players and power athletes may still find a place for it. Some data point to better sprint repeatability or muscle power. The return is just less steady than it is for classic endurance work.

How Much Beetroot Juice Per Day For Athletes In Real Terms

Labels, bottle sizes, and powder scoops can make this feel messy, so here is a practical chart. Use the nitrate number first when it is listed. Use the juice volume only as a rough backup.

Product Type	Usual Serving	Target Nitrate
Concentrated beetroot shot	70 mL	About 6 to 8 mmol
Two smaller concentrate shots	2 x 70 mL	Often 8 to 12 mmol total
Regular bottled beet juice	250 to 500 mL	Check label; varies a lot
Homemade beet juice	Varies	Hard to pin down
Beetroot powder	Brand-specific scoop	Only count it if nitrate is listed
Race-day single dose	1 serving 2 to 3 hours pre-event	6 to 8 mmol
Short loading plan	Daily for 3 to 6 days	6 to 8 mmol each day
High-dose plan	More than standard	May not beat 6 to 8 mmol

What To Avoid If You Want It To Work

One odd detail matters a lot: do not use antibacterial mouthwash right before nitrate loading. The bacteria in your mouth help turn nitrate into nitrite, which is part of the chain that leads to nitric oxide. Kill off that step and the whole plan can lose some punch.

Also, do not test beet juice for the first time on race day. Some athletes get stomach upset, bloating, or a sloshy feeling if they take a large volume too close to the start. Another harmless side effect is pink or red urine and stools. It can look alarming if you are not expecting it.

If you already eat a lot of high-nitrate vegetables, you may still get a lift from a measured pre-event dose, but the jump may feel smaller than it does for someone whose diet is low in nitrate-rich foods.

Regular Juice Vs Concentrated Shots

Concentrated shots win on convenience. You get the dose in a small volume, which is easier before hard training and far easier before racing. Regular juice can work too, but it may take a much bigger serving to hit the same nitrate target.

Homemade juice sounds nice and cheap, yet it has one weak spot: the nitrate content can swing due to growing conditions, storage time, and the beets themselves. If performance is the goal, a product with a declared nitrate amount is the safer bet.

Option	Main Plus	Main Catch
Concentrated shot	Small volume, easy to time	Costs more per serving
Regular beet juice	Easy to find in stores	You may need a lot more liquid
Homemade juice	Fresh and cheap	Nitrate level is a guess
Powder	Portable	Beetroot weight is not the same as nitrate dose

A Simple Dosing Plan For Training And Race Week

If you want a no-fuss routine, start here:

• For a hard session: 6 to 8 mmol nitrate 2 to 3 hours before training.
• For race day: the same single dose, tested in training first.
• For a target race: 6 to 8 mmol daily for 3 to 6 days, then your last dose 2 to 3 hours before the start.

That is enough for most athletes. More is not always better. In some trials, moving above the standard range did not add extra performance gain. If your product gives 8.4 mmol in one serving, you are already in a solid place.

When Beetroot Juice May Not Be Worth It

If your event is very short, very skill-heavy, or mostly low effort, the payoff may be tiny. The same goes for athletes who cannot tolerate the taste or the stomach feel. Beet juice is one tool, not a must-do habit.

It also should not crowd out the basics. Sleep, carbs, fluids, and a race plan still do more heavy lifting than any single supplement. Beetroot juice works best when those pieces are already in order.

The Daily Amount Most Athletes Can Start With

For most athletes, a smart starting point is one serving that provides 6 to 8 mmol nitrate per day. Use it 2 to 3 hours before the session when you want the effect, or take that same daily amount for a short loading block before a target event. In plain volume terms, that is often 70 mL of a concentrated shot or roughly 250 to 500 mL of regular beet juice, depending on the product.
