How long does it take to feel the effects of beets?

Beets are a nutritious root vegetable packed with essential vitamins, minerals, and plant compounds. They have become increasingly popular in recent years due to their many potential health benefits. One of the most common questions about beets is how long it takes to feel their effects after eating them. This article will explore the timeline for experiencing the benefits of beets, from digestion and nutrient absorption to specific health effects.

Digestion and Absorption of Beets

Like all foods, the nutrients in beets need to go through the digestive process before your body can absorb and utilize them. Here is a general timeline of what happens after eating beets:

  • Mouth: Chewing beets helps break them down and releases some nutrients.
  • Stomach: Beets are further broken down by stomach acids. This process happens quickly, within 30 minutes to an hour.
  • Small intestine: Nutrients from beets are absorbed through the small intestinal wall into the bloodstream. This starts around 1-2 hours after eating.
  • Large intestine: Leftover beet fiber helps feed the beneficial bacteria in your colon. This happens around 2-3 hours after your meal.

Overall, you can expect the nutrients from beets to start being absorbed into your system within 1-2 hours of eating them. Maximum nutrient absorption happens around 3-5 hours.

Nitrate Effects

One of the most studied compounds in beets is dietary nitrate. When nitrate enters your body, it gets converted into nitric oxide, which provides many benefits:

  • Improves blood flow and lowers blood pressure
  • Increases exercise performance and endurance
  • May improve brain function

Research shows that blood nitrate levels peak within 2-3 hours after eating a high-nitrate food like beets. The conversion to nitric oxide can take a bit longer, reaching its maximum effect around 6 hours post-consumption. Here is a more detailed timeline:

Time after eating beets Effect
1 hour Nitrate enters the bloodstream
2-3 hours Blood nitrate levels peak
3-6 hours Nitrate converts to nitric oxide, providing benefits
6+ hours Nitric oxide levels maximized, effects can last 8-24 hours

Therefore, it typically takes about 3-6 hours after eating beets to feel the maximum effects from their nitrate content. However, everyone metabolizes nitrate at slightly different rates.

Digestive Effects

Some people report digestive effects from eating beets, such as red or pink stools. This harmless side effect is caused by betalains, the pigments that give beets their rich color. Here’s when you might experience beeturia (pink urine) or red stools:

  • Beeturia: Within 12-24 hours of eating beets
  • Red stool: 24-48 hours after consuming beets

For some sensitive individuals, beets may also cause slight digestive distress like gas or bloating. This can begin within a few hours of eating them.

Blood Sugar and Blood Pressure Effects

Research shows beets may have moderate benefits for blood sugar and blood pressure control. Here’s when you might expect to see effects:

  • Blood sugar: Small decreases seen 2-4 hours after eating beets. May help prevent blood sugar spikes.
  • Blood pressure: Reduction in blood pressure observed 4-6 hours after consuming beets. Effects seem to persist up to 24 hours.

However, these benefits would need to be sustained through regular beet intake, not just a single meal.

Exercise Endurance Effects

Drinking beetroot juice prior to exercise or competition has become a popular athletic performance strategy. Here’s the timeline for benefits:

  • 30-90 minutes before exercise: Drink beetroot juice. Blood nitrate levels will peak in 2-3 hours.
  • 2-3 hours post-consumption: Conversion of nitrate into nitric oxide is maximized, which can improve oxygen flow and exercise efficiency.
  • Up to 6 hours post-consumption: Continued benefits on athletic performance.

To experience enhanced exercise endurance from beets, they need to be consumed 1-2 hours prior to training or competing. Benefits seem to last for up to 6 hours post-consumption.

Long-Term Effects

While a single serving of beets may provide a short-term benefit, regular beet intake is needed to experience the full effects. Here are some long-term health impacts of 1-2 servings of beets per day:

  • After 2-4 weeks: May see improvements in blood pressure, exercise performance, and heart health markers.
  • After 2-3 months: Reduction in oxidative stress and inflammation possible.
  • After 6-12 months: Potential decrease in risk for chronic diseases like heart disease and type 2 diabetes.

It takes time for the nutrients in beets to exert their full influence on health. But they key is maintaining beet intake as part of a healthy, balanced diet.


In summary, here is a review of approximately how long it takes to feel the benefits of eating beets:

  • 1-3 hours: Nutrient absorption starts.
  • 2-6 hours: Maximum effects from nitrates, including exercise performance.
  • 12-48 hours: Digestive effects like beeturia.
  • 2-6 hours: Moderate blood sugar and blood pressure benefits.
  • 2-4 weeks: Improvements in heart health markers and exercise endurance.
  • 2-12 months: Reduction in inflammation and chronic disease risks.

Of course, effects can vary based on the individual, dose of beets consumed, and whether they are eaten whole or juiced. But aiming to frequently incorporate beets into your diet can provide a boost to cardiovascular, athletic, and overall health over time.
