GRAPEFRUIT JUICE VS. ORANGE JUICE: WHICH IS BETTER FOR IMMUNE AND HEART HEALTH?

Medically reviewed by Suzanne Fisher, RD

Key Takeaways

• Orange juice and grapefruit juice have similar amounts of vitamin C. 
• Orange juice may lower cholesterol, while people taking statins, a type of cholesterol medication, should typically avoid grapefruit juice. 
• Including both in your diet may provide antioxidants that can benefit your heart health.

Orange juice is generally better for heart health and immune support compared to grapefruit juice, with the added benefit of having fewer drug interactions. While both juices offer significant vitamin C, orange juice may lower cholesterol without the risks posed by grapefruit juice for those on certain medications.

Nutritional Comparison

Here's how the nutrition of a small glass (100 grams, or about 3.5 ounces) of pulp-free orange juice stacks up against red grapefruit juice. Orange juice generally contains more calories, sugar, total carbs, and vitamin C compared to grapefruit juice.

​	Orange Juice	Grapefruit Juice
Calories	47 cal	41 cal
Protein	0.8 g	0.6 g
Total Fat	0.4 g	0.3 g
Carbohydrates	10 g	9.1 g
Sugar	8.1 g	7.1 g
Sodium	0 mg	1 mg
Vitamin C	30.5 mg	24.1 mg

Both Types Can Help Support Your Immune System

Both grapefruit juice and orange juice contain lots of vitamin C, which helps boost the immune system. Vitamin C is a powerful antioxidant that helps your cells repair themselves. Most adults need between 75 and 90 milligrams (mg) of vitamin C each day, meaning a small glass of either juice can provide about one-third of the recommended daily intake.

Orange juice offers 30.5 mg of vitamin C per 100 grams. Red grapefruit juice supplies 24.1 mg.Interestingly, white grapefruit juice contains even more vitamin C, providing 39.4 mg per 100-gram serving.

Orange Juice May Be Better for Cholesterol

If you're managing your cholesterol levels, consider reaching for the orange juice. A scientific review found that drinking orange juice daily may significantly reduce overall cholesterol. Researchers note that further study is needed to support this finding.

Grapefruit juice, on the other hand, is often not safe for people who take statins, a common type of cholesterol medication. It may interact with the drug, causing side effects or reducing its effectiveness. These particular statins are strongly impacted:

• Atorvastatin (Lipitor)
• Lovastatin (Mevacor)
• Simvastatin (Zocor)

If you're taking a statin, talk with your healthcare provider or pharmacist before drinking grapefruit juice or eating grapefruit.

Both May Help Prevent Stroke and Heart Disease

Sipping either grapefruit juice or orange juice could improve your heart health, provided you’re not on any medications that grapefruit juice interferes with. 

Grapefruit juice is a great source of flavonoids, antioxidants that can protect your body by reducing inflammation. The juice also contains lycopene, another antioxidant that may reduce the risk of stroke. Orange juice, by contrast, typically has a very small amount of lycopene.

However, orange juice has been shown to reduce blood pressure in some people, including those with excess body weight. In addition, studies have shown that drinking orange juice has a positive impact on several risk factors for cardiovascular disease, including cholesterol levels.

Neither Is a Magic Bullet for Weight Loss

Grapefruit has been tied to fad diets throughout the years, but neither grapefruit juice nor orange juice has strong evidence for weight loss. They can have a place in a well-balanced diet and bring important nutrients. Like all juices and sugary drinks, however, it's important to consume them mindfully in moderation. 

When to Avoid Grapefruit Juice or Orange Juice

Orange juice is generally safe for most people to drink. There are more precautions around grapefruit juice because it can interact with more medications. Avoid grapefruit and grapefruit juice if you take any of these drugs:

• Statins and blood pressure drugs, including nifedipine
• Certain organ-transplant rejection drugs
• Some drugs for anxiety, including buspirone (BuSpar)
• Some steroids used to treat Crohn's disease or ulcerative colitis, including budesonide (Entocort EC and Uceris)
• Amiodarone (Pacerone and Cordarone), used to treat abnormal heart rhythms
• Some antihistamines, including fexofenadine (Allegra)

When in doubt, talk with your doctor or pharmacist about whether grapefruit juice or orange juice is safe with your medications.
