Is orange juice Good for you before a workout?

Orange juice is a popular beverage choice for many people looking to get an energy boost before exercise. It’s known for being rich in vitamin C and provides carbohydrates for fuel. But is orange juice the best option to drink before a workout? There are a few factors to consider.

The Potential Benefits of Orange Juice Before Exercise

Here are some of the main reasons why people choose to drink orange juice before working out:

  • It contains simple sugars – Orange juice has a high glycemic index, meaning its sugars are quickly absorbed and can provide fast energy.
  • Hydration – It consists of approximately 88% water, so it can help hydrate the body.
  • Vitamin C – One cup provides over 100% of the RDI for vitamin C, an antioxidant that supports immune function.
  • Potassium – Orange juice contains potassium, an electrolyte that helps regulate fluid balance.

The carbohydrates, fluids and electrolytes in orange juice may help give you an energy boost before exercising and prevent dehydration. The vitamin C also supports immune function during periods of intense training.

The Potential Downsides of Orange Juice Before Exercise

Despite the potential benefits, there are some drawbacks to consider with drinking orange juice before a workout:

  • High glycemic index – The quick spike in blood sugar may lead to an energy crash.
  • Acidity – The citric acid may cause digestive discomfort when consumed before physical activity.
  • Sugary calories – The 112 calories in a cup are mostly sugar, providing little nutritional value.
  • Dehydration – The combination of fluids and sugars could delay hydration compared to water.

The high glycemic index is one of the main concerns, as the surge in blood sugar occurs rapidly but doesn’t last. This could negatively impact energy levels later in the workout. The acidity and sugars may also cause stomach discomfort when consumed right before exercise.

How Long Before Your Workout Should You Drink Orange Juice?

If you choose to drink orange juice before your workout, timing is important. Here are some general guidelines on when to consume it:

  • 1-2 hours before – This allows time for digestion and full absorption into the bloodstream.
  • 30-45 minutes before – For a moderate energy boost right before you start exercising.
  • During exercise – Small amounts can help replenish energy and supply fluids/electrolytes.
  • Right after – To help replenish glycogen stores and rehydrate.

Drinking orange juice 1-2 hours prior gives you the benefits without the drawbacks of consuming it right before a workout. Smaller amounts can be beneficial during and after exercise when rapid absorption is helpful.

How Much Orange Juice Should You Drink Before a Workout?

Moderation is key when it comes to orange juice intake around exercise. Here are some recommendations on amounts:

  • 1-2 hours before: 4-8 oz (125-250ml) provides carbohydrates for energy.
  • 30 minutes before: 4-6 oz (125-175ml) for a light pre-workout boost.
  • During: 3-4 oz (100ml) every 15-30 minutes to replenish energy.
  • After: 8-12 oz (250-375ml) to help muscles refuel and rehydrate.

Too much orange juice can lead to an energy crash or stomach upset. Focus on smaller amounts spread over time for optimal timing and absorption. Water should be your primary hydration source.

How Does Orange Juice Compare to Other Drinks Before Exercise?

Here’s how orange juice stacks up against some other common pre-workout drink choices:

Drink Benefits Downsides
Orange juice
  • Provides carbohydrates
  • Contains electrolytes
  • Rich in vitamin C
  • High glycemic index
  • Can cause stomach upset
  • High in sugary calories
Coconut water
  • Natural source of electrolytes
  • Low acidity
  • Low glycemic index
  • Lower carbohydrate content
  • Minimal protein
Sports drinks
  • Formulated with electrolytes
  • Contains carbohydrates
  • Specific ratios for rehydration
  • Highly processed
  • Often high in sugars
  • Some contain artificial ingredients

Coconut water and sports drinks formulated for athletic performance provide a more tailored approach for pre/post workout hydration. But orange juice can still be a reasonable choice in moderation.

General Tips for Consuming Orange Juice Around Exercise

Here are some tips to get the benefits of orange juice while minimizing potential downsides:

  • Consume 1-2 hours before workouts for best energy timing.
  • Drink only 4-8 oz as your pre-workout beverage.
  • Avoid large amounts within 30 minutes before activity.
  • Mix it 50/50 with water to cut acidity and sugars.
  • Pair with protein/fat for sustained energy and delayed absorption.
  • Alternate with coconut water or nutrition shakes.
  • Focus on proper hydration with water while training.

Following these tips will help you better manage your energy levels, stomach comfort and hydration around workouts while still benefiting from some of the key nutrients in orange juice.


Orange juice can be a reasonable beverage choice before exercise when consumed in moderation. The carbohydrates, vitamins and minerals it provides can help boost energy, immunity and electrolyte levels. However, its high glycemic index, acidity, and high sugar content need to be taken into consideration. Ultimately, water should be your go-to hydration source before, during and after workouts. But orange juice can provide a nutritional boost when timed appropriately and paired with other foods.
