Beets, or beetroots, are a versatile root vegetable celebrated for their rich nutritional profile and earthy flavor. Their high concentration of inorganic nitrates is the key to many of their most lauded benefits. When consumed, your body converts these nitrates into nitric oxide, a molecule that helps relax and widen blood vessels, which in turn improves blood flow and can lower blood pressure. However, to properly harness these effects, strategic timing is important.
Timing for Specific Health Goals
For Lowering Blood Pressure
For those looking to manage or reduce high blood pressure, the morning appears to be the most strategic time to consume beets, particularly in juice form. Studies suggest that drinking beetroot juice on an empty stomach about 30 minutes before breakfast may lead to better absorption of nitrates. This timing helps your body’s naturally low nitric oxide levels first thing in the morning, and the effects can last up to 6–10 hours, supporting healthy blood pressure throughout the day. It's important to remember that this effect is temporary, so consistent daily consumption is recommended for sustained benefits.
For Boosting Athletic Performance
For athletes and fitness enthusiasts, timing beets to align with a workout or competition is crucial for a performance edge. The nitrates in beets help improve oxygen use by your muscles, extending endurance and reducing fatigue. To maximize these effects, studies recommend consuming beets or beet juice 2–3 hours before training or an event. This window allows blood nitrate levels to peak and the conversion to nitric oxide to occur at the optimal time for peak performance. Whole beets take longer to digest than juice, so adjusting your timing based on your chosen form is wise.
For Aiding Digestion and Overall Wellness
Beets are a good source of dietary fiber, which is crucial for promoting healthy digestion and preventing constipation. Fiber content helps regulate bowel movements and feeds beneficial gut bacteria. For general digestive health, incorporating beets into your meals at any time of day can be beneficial. However, some health proponents suggest that consuming beets in the morning can help kick-start your digestive system for the day. Fermented beet products, like beet kvass, are also excellent for providing probiotics, which support gut health.
For Supporting Restful Sleep
While not a stimulant, beets contain nutrients that can support better sleep. For some individuals, drinking beet juice in the evening may contribute to a more restful night's sleep. This effect is potentially due to the nitrates improving blood circulation and oxygen flow. However, some people may be sensitive to the mild energy boost and the diuretic properties of beets, which could interfere with sleep. Pay attention to how your body responds and adjust accordingly.
Whole Beets vs. Beet Juice: Timing and Absorption
| Feature | Whole Beets (Raw or Cooked) | Beet Juice (Fresh or Concentrate) |
|---|---|---|
| Digestion Time | Slower due to high fiber content | Much faster, allowing for rapid absorption |
| Peak Effect | Takes longer to see performance benefits | Peak blood nitrate levels within 2–3 hours of consumption |
| Nitrate Content | Varies widely based on soil and preparation | Often standardized, providing a consistent, concentrated dose |
| Best For... | General dietary fiber, daily nutrition, and sustained health benefits. | Athletic performance, blood pressure control, or targeted, rapid effects. |
| Consideration | Might cause gastrointestinal discomfort if eaten in large quantities pre-workout. | Concentrated juice lacks fiber; watch for sugar content, especially for those with diabetes. |
How to Incorporate Beets Into Your Diet
There are numerous ways to add beets to your meals, each offering a slightly different nutritional profile. Here are some popular methods:
- Raw: Grate raw beets into salads or slaws for a crunchy, earthy texture.
- Roasted: Roasting beets brings out their natural sweetness. Rub them with olive oil, salt, and pepper and roast until tender.
- Juiced: Blend with other fruits and vegetables like oranges, carrots, or ginger for a nutrient-packed beverage. This is the most efficient method for maximizing nitrate intake for performance.
- Pickled: Pickled beets can be made through traditional canning or fermentation (like kvass) for added probiotic benefits.
- Boiled: Boiling beets is a simple method, but since nitrates are water-soluble, some can be lost in the cooking water. To maximize nitrate content, roasting or consuming raw is better.
For athletes, beetroot juice shots can be a convenient option for precise pre-workout timing. The key is to experiment to find what works best with your body and your schedule. Always test a new food or supplement on a low-stakes training day before a major event to avoid unexpected gastrointestinal issues.
Conclusion
There is no single best time of day for everyone to eat beets; rather, the ideal timing is a personalized strategy based on your health goals. For managing blood pressure, morning consumption is most effective at targeting the natural daily peak. For boosting athletic endurance, a pre-workout dose 2–3 hours prior is recommended to maximize the nitric oxide effect. For general digestive health, incorporating beets into a meal at any time of day can provide a beneficial fiber boost. By understanding your body's specific needs and the unique properties of beets, you can intentionally time your intake to reap the maximum health rewards.

What are the benefits of eating beets in the morning?
Morning consumption, particularly of beet juice, is ideal for managing blood pressure as it helps blunt the natural rise that occurs during the day. It can also provide a steady release of nitrates, supporting general energy levels throughout your day.
Should I eat beets before or after a workout?
For maximum athletic performance benefits, you should consume beets or beet juice 2–3 hours before a workout. This timing allows your body's nitric oxide levels to peak, which enhances oxygen use and endurance.
Is it okay to eat beets at night?
Yes, it is generally safe to eat beets at night. For some, the improved circulation can support restful sleep. However, those sensitive to its mild energy boost or high fiber content might prefer to consume them earlier in the day to avoid sleep disruption or gas.
How does timing affect blood pressure when eating beets?
Timing beets in the morning can help regulate blood pressure throughout the day by providing a boost of nitric oxide just as blood pressure naturally begins to rise. The effects of nitrates are temporary, so a morning dose offers sustained support for several hours.
Is beet juice better than whole beets for timing benefits?
Beet juice offers a more concentrated and rapidly absorbed source of nitrates, making it more effective for targeting specific timing goals like pre-workout performance. Whole beets, with their fiber, offer more sustained nutritional benefits and are better for daily intake.
How much beet juice should I drink for athletic performance?
Research suggests that a dose of beet juice equivalent to about 5-9 mmol of nitrate, consumed 2–3 hours before exercise, can be effective. For some, this might be around 70-140 ml of concentrate or a couple of glasses of regular juice.
What is the best way to cook beets to preserve nitrates?
Since nitrates are water-soluble, methods like roasting or eating them raw are better for preserving the nitrates compared to boiling. Roasting also concentrates their flavor, making them a delicious addition to many dishes.
