Key Takeaways
Drinking a small glass of 100% orange juice daily can boost your intake of vitamin C, potassium, and folate, supporting immunity, heart health, and hydration.Because juicing removes most of the fiber, orange juice delivers concentrated natural sugars that can spike blood sugar and add extra calories if consumed in large amounts.To keep it balanced, choose options with no added sugar (and ideally added calcium or vitamin D), limit portions to about 4 ounces, and pair it with a meal rather than sipping it solo.

Next to coffee, orange juice is one of the most popular ways to start the day in America—it’s tart, sweet, and oh-so satisfying. And while OJ offers many of the same health benefits as whole oranges, there are some key differences. Not to mention that many brands contain added ingredients that you wouldn’t find in an orange (and want to limit on a regular basis).

Orange juice is often a regular part of many people’s daily routines—but what actually happens in the body if you drink it every day? Here, we’ll dive into the nutrition of orange juice, what to look for in healthier brands, and what happens in the body when you consume it on a daily basis.

From this, we can see that although orange juice doesn’t provide a wide range of nutrients, the ones it does contain are present in significant amounts. “One serving of 100 percent orange juice gives you more than a full day’s worth of vitamin C to help support immune health, plus potassium for heart health and fluid balance, and folate for healthy cell growth,” explains Kaitlin Hippley, M.Ed, RDN, LD, CDCES, certified diabetes educator and registered dietitian in Cleveland, Ohio. These nutrients also support bone density, iron absorption, and skin health. Plus, you can find plant compounds like hesperidin in OJ, which further boosts immunity.

There are plenty of fortified orange juices on the market, too, which offer additional nutrition. “Fortified varieties can provide calcium and vitamin D, making orange juice a convenient way to support bone health,” explains Dani Dominguez, MS, RDN, registered dietitian nutritionist, certified pet nutritionist, and founder of SunBright Wellness.

The juicing process concentrates the nutrients found in oranges—which is good and bad news. “With the exception of fiber, a half cup of orange juice offers many of the same essential nutrients as about three oranges squeezed into a glass, like loads of vitamin C, potassium, and folate,” adds Shaira Daya, MPH, RDN, menopause dietitian and culinary nutritionist. 

However, juicing also concentrates the carbohydrate load of this citrus product. “Orange juice is a concentrated source of natural sugars that lacks the fiber present in the whole fruit. Without fiber to slow down digestion, the sugars are absorbed quickly, which can lead to spikes in blood sugar and insulin in the body. This may not trigger the same sense of fullness you would get as if eating the whole fruit,” offers Dominguez. 

Daya agrees, adding: “Sugar-rich drinks, including 100 percent fruit juice, contain a surprising amount of calories that can lead to unintended weight gain if consumed regularly or in high amounts.” Additionally, many orange juice brands contain additives and preservatives that warrant more research to understand their long-term health impacts, as well as pro-inflammatory added sugar.

What Happens When You Drink Orange Juice Every Day? 

With these nutritional attributes in mind, what can you expect if you reach for a glass of orange juice on a daily basis?

“Enjoying a glass of 100 percent orange juice each day can be a simple way to add key nutrients like vitamin C, potassium, and folate to your diet. Over time, it may support immunity, heart health, and overall nutrient intake,” shares Hippley.

Research even shows that it may help keep certain chronic illnesses at bay. “Recent studies suggest that consumption of natural juices, like orange juice, was associated with a lower risk of dementia, reduced risk of chronic obstructive pulmonary disease, and improvements in blood pressure regulation, inflammation, as well as lipid metabolism,” says Dominguez.

Plus, this juice counts towards your daily fluid goals. “Orange juice can help us stay cool and hydrated in hot weather, and can be a refreshing source of fluid and energy when we’re sick,” adds Daya.

That said, all three RDs agree that considering the downsides of this tasty juice, it should be enjoyed in moderation and not as a substitute for whole oranges. “Because [orange juice] is naturally sweet and low in fiber, drinking it in large amounts could contribute to extra calories or spikes in blood sugar. Choosing options with added calcium or pulp can offer subtle differences in nutrients, but the most important factor is enjoying juice in moderation as part of a balanced diet,” Hippley affirms.

It’s also important to note that this citrus juice is more acidic than many other juice options. “Orange juice is highly acidic, and over time could soften and erode tooth enamel if consumed regularly,” Dominguez explains. Considering this juice’s sugar load, higher calorie content, acidic nature, and lack of fiber, Daya doesn’t generally recommend making OJ a part of her clients’ daily routine. 

That said, if you can’t part with your daily glass of orange juice, there are plenty of ways to make it a healthier choice. Look for an option that’s fortified with calcium and vitamin D to get more nutritional bang for your buck, and steer clear of brands containing mystery ingredients and/or added sugar. The fewer ingredients (ideally just oranges), the better. Most minimal ingredient orange juices will be found in the refrigerated section of the grocery store.

How you enjoy OJ can make a difference, too—particularly when it comes to blood sugar response. “Pairing juice with a meal or snack can help balance blood sugar and keep you satisfied,” says Hippley. Moderation can also be really impactful in this regard. “Aim for no more than four ounces or half a cup at a time,” adds Daya.
