When to Take Beetroot Capsules, and Why.

The short answer: The well-known beet window, about 2.5 to 3 hours before exercise, comes from juice: the NIH says studies usually had people drink 2 cups of beet juice that far ahead. Our capsule label ties its serving to a meal instead, with two capsules once a day, 20-30 minutes before eating. So when to take beetroot capsules on a training day means picking the meal a few hours before you train.

Key takeaways

• The label on Betterly's Organic Beetroot Capsules directs two capsules once a day, 20-30 minutes before a meal, with an 8 oz (237 ml) glass of water.
• The 2.5-to-3-hour pre-exercise timing traces back to beet juice, not capsules, according to the NIH Office of Dietary Supplements.
• On training days, you can stay on the label and still plan around a workout by choosing which meal the capsules go before.
• The beetroot capsule panel lists no caffeine source, so there's no buzz to wait for and evening use adds no caffeine to your day.
• The label sets one 2-capsule serving a day and says not to exceed it, so a race or a hard session doesn't call for extra.

Betterly sells the three products named in this guide: these capsules, a beet and hibiscus drink mix, and citrulline-and-arginine capsules. Their labels never mention exercise, so the workout timing ideas below are ours, worked out inside each label's directions rather than printed on any bottle.

When should you take beetroot capsules?

Take two of Betterly's Organic Beetroot Capsules 20-30 minutes before one meal a day, and let your training schedule pick the meal.

The directions on the bottle name an amount, a glass of water and a meal, and nothing else: "As a dietary supplement take two (2) capsules once a day. For best results take 20-30 min before a meal with an 8oz (237ml) glass of water or as directed by your healthcare professional." You won't find a workout, an hour or a specific meal in there.

That open choice matters with beet, since plenty of people want to line it up with exercise. On rest days, any meal at a regular hour does the job. On training days, the table below shows which meal lands closest to the juice-study timing.

The only active ingredient on the panel is organic beetroot powder (Beta vulgaris), at 1,300 mg per 2-capsule serving.

Why does the label say before a meal, not before a workout?

The beetroot capsule label ties its timing to a meal without saying why, and it never mentions exercise. The workout window you see quoted comes from juice research.

Here's where that window starts. The beetroot entry in the NIH Office of Dietary Supplements (ODS) guide to exercise and athletic performance supplements calls beets one of the best food sources of nitrate. It also says study volunteers usually drank 2 cups of beet juice about 2.5 to 3 hours before exercising.

The same entry adds a caveat for anyone holding capsules: no one knows yet if a supplement made with beetroot powder does what the juice did.

When the bottle and the research point to different times, follow the bottle. Its directions were written for this capsule at 1,300 mg, while the study window describes 2 cups of juice.

When to take beetroot capsules on a training day

On a training day, take beetroot capsules before a meal that falls a few hours ahead of your workout, which keeps you on the label while planning around exercise.

If you already eat about 2.5 hours before you train, taking your capsules 20-30 minutes before that meal puts them roughly 3 hours out. That's as close to the juice timing as the label gets. Swallowing capsules in the gym parking lot right before a session matches neither source.

Only the dinner row sits inside the juice window, and late morning just brushes its edge. That's fine. Every row follows the label, and ODS leaves open whether that window applies to a beetroot powder capsule at all.

ODS also puts limits on the research itself. Much of it is done in young, healthy men, and a study in one sport might not apply to another, so a cyclist's result may not describe your Saturday run. It adds that juice tends to make more difference for recreational exercisers than for highly trained athletes.

Is morning or evening better for beetroot capsules?

Neither morning nor evening wins, because the beetroot capsule label names a meal, not a clock time. Go with whichever meal happens at a predictable hour for you.

Breakfast suits you if mornings are the calmest part of your day. Lunch suits afternoon trainers, as the table shows. Dinner works too: the panel lists beetroot powder and no caffeine source, so an evening serving adds no caffeine to your day.

What the label doesn't describe is a bedtime dose with nothing to eat after it. People often search whether beetroot is good before bed, but the before-a-meal wording points you toward dinner, not your pillow.

How long does beetroot take to work?

Nobody can honestly give you a timeline for beetroot capsules. Our label names none, and ODS says the juice findings may not carry over to beetroot powder supplements.

If you mean the gap before a workout, that 2.5-to-3-hour figure describes how juice was timed in studies. If you mean days or weeks, no label claim or federal source we checked covers that, and we won't make up a number.

Keep in mind that beetroot isn't a stimulant, so there's no lift 20 minutes later the way there is with coffee. If a fast lift is the goal, our pre-workout vs energy drink guide covers caffeine timing.

One change you might see is color. Beets can tint urine pink or red, a change both ODS and MedlinePlus's page on urine color mention. When beets are the reason, the tint says nothing about whether the capsules are doing anything, so it isn't a progress bar. MedlinePlus also advises seeing a provider when urine turns pink or red and no food or medicine explains it.

How many beetroot capsules per day?

Betterly's beetroot capsule label sets the daily amount at two capsules, taken once, for 1,300 mg of organic beetroot powder per 2-capsule serving.

A 60-capsule bottle holds 30 servings, about a month at the labeled amount. The panel marks the beetroot row with a double asterisk, meaning no Daily Value has been set, so the label is your only guide to how much. It says two capsules once a day, which means a split dose isn't what it describes. Extra before a big race is out too: the caution reads "Do not exceed recommended dose."

Our directions don't carry over to other beetroot pills or tablets. If you switch brands, these parts of the new label set your schedule:

1. Serving size: how many capsules make one serving, and how many milligrams of beetroot that holds.
2. How often: once a day, twice a day or no frequency at all each changes the plan.
3. Food wording: before, with or after a meal changes where it sits in your day.
4. Anything besides beet: if the panel adds caffeine or green tea, evening timing becomes a different question.

When is the best time to take beet powder?

Betterly's Beetroot & Hibiscus Powder label names no time of day. It says to stir one scoop into 6-8 oz of cold water or your favorite beverage once a day, and to drink it within 10 minutes.

The panel shows beet root powder at 1,375 mg, hibiscus powder at 1,000 mg and apple juice powder at 500 mg per 1-scoop (3.25 g) serving. With no meal named, the best time is any moment you can drink the whole glass right after mixing.

Beet powder before a workout follows the same logic as the capsules: fine if it suits your day, but the study window still describes juice. For mixers, see our guide to how to drink beet powder, and for amounts across formats, our beet powder, juice and capsule comparison.

If you own both, treat them as alternates, not a pair: each label describes one complete serving a day on its own.

From our shop: Beetroot & Hibiscus Powder — a cold-water drink mix with 1,375 mg of beet root powder and 1,000 mg of hibiscus powder per 1-scoop (3.25 g) serving, and no meal timing on the label.

Can you take beetroot capsules with citrulline or a pre-workout?

The directions on our beetroot capsules and our citrulline-and-arginine capsules don't conflict on timing, but no label or federal source we checked covers taking them together. ODS points out that researchers haven't tested most ingredient combinations sold for exercise.

Our L-Citrulline & L-Arginine Capsules list 400 mg of L-citrulline DL-malate, 350 mg of L-arginine hydrochloride and 50 mg of L-arginine alpha-ketoglutarate per 2-capsule serving. That label says two capsules daily with 6-8 oz (177-237 ml) of water and names no meal. ODS finds little scientific evidence for arginine as a performance supplement, and not much for citrulline.

If you use both, each keeps its own directions. Our guide to taking beetroot and citrulline together looks at that pairing. With a caffeinated pre-workout, the beetroot capsules add nothing to your caffeine total, and the pre-workout's own label decides its timing.

How to take beetroot capsules, step by step

To take Betterly's Organic Beetroot Capsules as labeled, swallow two with 8 oz of water 20-30 minutes before one meal each day.

1. Settle on the meal first. On training days, the one a few hours before your session makes sense; on other days, go with whichever meal keeps the most regular hours.
2. Store the bottle near where that meal happens, in a spot that's cool, dry and out of children's reach, as the label asks.
3. Swallow two capsules with a full 8 oz (237 ml) glass of water, then eat 20-30 minutes later.

Linking the capsules to one meal also makes each day easy to account for: once lunch has happened, so has today's serving. Our walkthrough for setting up a daily supplement routine has more on making that stick.

If you're weighing a caffeine-free option like beet against caffeinated ones for the hours before training, our Energy Support collection carries both kinds.

When you don't need beetroot capsules

You can skip beetroot capsules if no meal in your day is regular enough to pair them with, or if you'd only ever take them minutes before training.

• Your meals don't keep a schedule. The label needs food 20-30 minutes after the capsules, which is hard to plan when you eat on the run.
• You'd take them right before training. Capsules swallowed minutes before a session fit neither the label's meal timing nor the 2.5-to-3-hour juice window.
• You want the juice-study window in capsule form. ODS says it isn't known whether beetroot powder supplements act like juice, so no capsule, ours included, can promise that window.
• Your basics are shaky. ODS says you'll perform at your best on a nutritious diet, enough fluids and proper training, and no capsule stands in for those.

Who should check with a healthcare provider first?

Check with a healthcare provider before taking beetroot capsules if you're pregnant, nursing, under 18 or have a medical condition. That list comes straight from the label's caution.

Talk to a provider first in these situations too:

• You take any prescription medication. ODS flags possible interactions between sports supplements and medicines as something to check before you start.
• You have surgery coming up. The ODS primer Dietary Supplements: What You Need to Know warns that some supplements taken before an operation can change your response to anesthesia, so give your surgical team your full list.
• You want a different schedule. The label defers to "your healthcare professional," so a split dose or new time should come from them.

That same primer suggests keeping a written record of every supplement and medicine you take, with the dose and how often. Add the meal you pair these capsules with.

FAQ: beetroot capsule timing

Can you take beetroot capsules on an empty stomach?

For a short gap, yes: beetroot capsules go down 20-30 minutes before a meal, so your stomach may be empty, but food is always on its way. The case the label doesn't cover is a fasted morning workout where the capsules go down at 6 a.m. and breakfast waits until 9. If you train before eating, take them before your post-workout breakfast instead.

Should you take beetroot capsules on rest days?

Yes, beetroot capsules follow the same once-a-day direction on rest days, because the label never mentions training. The only thing that shifts is which meal you pick. With no session to plan around, choose the meal you're surest to eat at its usual time.

Can you take beetroot capsules with coffee?

Our label and the federal sources we checked don't cover beetroot capsules with coffee, so we can't point to any known issue or upside. Beetroot powder is the only active on the panel, so your cup stays your only caffeine source. Before breakfast, swallow them with the label's 8 oz of water rather than washing them down with coffee.

Can teenagers take beetroot capsules before sports?

Not without a physician's go-ahead: the beetroot capsule label tells anyone under 18 to consult one first. The NIH fact sheet on exercise supplements adds that in most cases only adults should use performance supplements. It cites the American Academy of Pediatrics' position that these products don't lift teenage athletes' abilities past what proper nutrition and training deliver. Our beetroot capsule side effects guide covers what else to raise.
