What happens if you drink too much orange juice?

Orange juice is a popular beverage that many people enjoy as part of a nutritious breakfast. With its vitamin C, potassium, and other nutrients, orange juice can be a healthy part of your diet when consumed in moderation. But what happens if you drink too much of it? Keep reading to learn more.

Nutritional Content of Orange Juice

Before examining the potential effects of overconsumption, let’s first look at the nutritional makeup of orange juice.


Nutrient Amount in 8 oz
Calories 112
Total carbohydrate 25 g
Sugars 21 g
Protein 2 g

As you can see, orange juice is high in natural sugars with over 20 grams per 8 ounce serving. The American Heart Association recommends limiting added sugar intake to no more than 25 grams per day for women and 36 grams per day for men. Just one glass of orange juice already provides 85-84% of the recommended daily added sugar intake.


Nutrient Percentage of Daily Value
Vitamin C 135%
Folate 11%
Potassium 14%
Thiamin 7%

Orange juice is an excellent source of vitamin C, providing over 100% of the recommended daily value per serving. It also contains Folate, Potassium, and other key micronutrients. However, these vitamins and minerals come along with lots of natural sugar.

Potential Effects of Drinking Too Much

What could happen if you consistently drank more than the recommended serving of orange juice per day? Here are some potential effects:

Weight Gain

Since orange juice is high in calories and sugar, drinking too much can lead to excessive calorie intake and weight gain over time. The natural sugars in juice are absorbed quickly into the bloodstream, spiking blood sugar and insulin levels which can increase hunger and lead to overeating.

To avoid weight gain, stick to a 4-8 oz serving of orange juice per day and focus on getting vitamins and minerals from whole fruits and vegetables as well.

Tooth Decay

The citric acid in orange juice can erode tooth enamel over time, increasing the risk of cavities and tooth decay. Plus, the sugars feed the bacteria that produce plaque and acids that further damage teeth.

To help protect teeth, avoid sipping orange juice throughout the day. Drink your small glass quickly at breakfast and brush teeth well afterwards.

Digestive Issues

Too much orange juice may provoke gastrointestinal problems like bloating, gas, abdominal cramping, and diarrhea in some individuals. This is due to the combination of sorbitol, fructose, and soluble fiber in oranges.

Pay attention to how your digestive system handles orange juice. Limit intake to 8 ounces per day and dilute with water if you experience intestinal distress.

Blood Sugar Spikes

While oranges have a relatively low glycemic index, orange juice causes blood sugar to rise very quickly due to its liquid form. In those with diabetes or insulin resistance, this could worsen blood sugar control.

To prevent blood sugar spikes, have a whole orange instead of juice and always combine orange juice with a protein source like eggs or nuts.

Increased Heartburn

The acidity of orange juice may relax the lower esophageal sphincter, allowing stomach acid to travel back up into the esophagus causing heartburn. Lying down within 2-3 hours after drinking juice can make this worse.

Those prone to heartburn should limit orange juice and avoid drinking it before bedtime.

Medication Interactions

Drinking large amounts of orange juice daily could potentially cause too much vitamin C or potassium, which can interfere with some medications.

For instance, orange juice may enhance the blood thinning effects of Warfarin. It’s also high in potassium, which can be problematic for those taking certain diuretics or heart medications.

Consult your physician if you take any prescriptions and want to drink orange juice regularly.

Kidney Stones

Orange juice contains a compound called oxalate that can contribute to kidney stone development in susceptible individuals. Consuming vitamin C in excess may also increase kidney stone risk.

If you’ve had kidney stones in the past, talk to your doctor about limiting foods high in oxalates like orange juice.

Healthiest Ways to Enjoy Orange Juice

Within moderation, orange juice can be part of a healthy diet. Here are some tips for enjoying it in a nutritious way:

– Have just 4-8oz per day – less is more when it comes to juice.

– Always combine it with protein like eggs, nuts, or lean meat to prevent blood sugar spikes.

– Avoid sipping juice throughout the day. Drink it alongside a meal instead.

– Water it down to cut back on sugar content.

– Brush teeth well after drinking to prevent acid from damaging enamel.

– Wait at least 2 hours after drinking before lying down to minimize heartburn.

– Opt for fresh-squeezed instead of heavily processed juice.

– Consider diluting with mineral water instead of plain water.

– Drink whole oranges more often since they have fiber and cause less sugar spike.

When to Avoid Orange Juice

Certain individuals may need to avoid orange juice entirely, including:

– Those with diabetes or blood sugar regulation issues

– People prone to kidney stones

– Anyone with gastroesophageal reflux disease (GERD)

– Individuals taking blood thinners like Warfarin

– Anyone taking potassium-sparing diuretics

– People who experience digestive issues from drinking juice

If orange juice gives you problems, don’t force yourself to drink it just because it’s healthy. The cons may outweigh pros in your specific case. Focus instead on getting vitamin C from other sources like bell peppers, broccoli, strawberries and kiwi which don’t pose same downsides.

The Bottom Line

When consumed in moderation, orange juice can provide important vitamins and minerals. However, drinking too much may lead to weight gain, tooth decay, digestive issues, medication interactions, and more. Maximize the health benefits of orange juice by sticking to a 4-8oz serving per day, combining it with protein, and practicing proper dental hygiene. Dilute with water or mineral water to cut the sugar content. For certain individuals prone to kidney stones or reflux, avoiding orange juice altogether may be best.
