The True Benefits and Risks of Drinking Aloe Vera Juice

Aloe vera juice is all the rage, but is it really as healthful as enthusiasts claim? Top nutritionists unpack the benefits and risks of aloe vera juice.

Cold-pressed aloe vera juice is popular at juice bars across the country due to its reported super-hydrating properties as well as its other potential benefits for digestive health, immunity, skin, blood sugar, and more. If it’s green, it has to be good for you, right? Yes, and no.

Most nutritionists agree that topical aloe vera gel can be safely rubbed on skin to soothe sunburns and other ailments. But they aren’t quite convinced of the benefits of drinking aloe vera juice.

Still, aloe vera juice is a rising trend among thirsty wellness seekers. The global aloe vera juice market is expected to reach $1.7 billion by the end of 2026 and is predicted to grow at a rate of about 8.9 percent each year, according to a report from 360 Research Reports, a market research group.

What is aloe vera?

A succulent plant found mainly in tropical regions, aloe vera has been used in medicine for more than 6,000 years. The clear gel and yellow latex from this plant may be responsible for its healing properties. These two substances are commonly used in aloe-based health products, including aloe vera juice, according to the National Center for Complementary and Integrative Health (NCCIH).

Aloe vera is chock-full of vitamins and minerals

Aloe vera contains more than 75 different health-boosting compounds, including antioxidant vitamins A, C, and E; vitamin B12; and minerals such as zinc, copper, selenium, potassium, and calcium, according to research in the March 2020 issue of Molecules. These are some of the reasons that Erika Laurion, a dietitian in Hudson, New York, thinks of aloe vera juice as a cure-all.

Aloe vera is an immune system booster

Aloe vera juice is an immune system stimulant because of a substance called acemannan, Laurion says. “It also has anti-viral properties. It can soothe coughs and help with asthma.” Aloe vera is anti-inflammatory and contains salicylic acid for pain and inflammation relief, she says. Salicylic acid is the active ingredient in aspirin and related compounds. This may be why aloe can help reduce pain associated with osteoarthritis and can be a fever reducer, NCCIH notes. “It also blocks histamine,” Laurion says. Histamine is a chemical released by your immune system when your body encounters an offending allergen, explains the American Academy of Allergy, Asthma & Immunology.

Aloe vera can tame tummy troubles

Aloe vera juice helps balance good and bad bacteria in the gut, which can alleviate some tummy troubles, including constipation. Aloe latex is sometimes used as a laxative to treat constipation, NCCIH notes. The latex contains anthraquinones such as aloin which help you go to the bathroom, according to the National Institute of Environmental Health Sciences. Exactly how much of this potent laxative is in aloe vera juice is unclear, but an aloe vera trade association sets the upper limit for safety at 10 milligrams of aloin per kilogram of body weight for aloe. But there’s a catch: Companies are not required to list aloin content on their labels.

… But use caution

Aloe vera was widely marketed as an over-the-counter laxative for a while, but in 2002, the U.S. Food and Drug Administration ruled that it could no longer be sold as one because of safety concerns, including cancer risk. These laxative properties can also decrease the absorption and effectiveness of some medications, says Elena Fraga, RD, Diabetes Program Manager at The Diabetes Alliance at the Mount Sinai Health System in New York City. Tell your doctor about any and all supplements you take to make sure there are no dangerous interactions.

Aloe vera may help with blood sugar

If you have diabetes or prediabetes, aloe vera juice may help you achieve reductions in fasting blood sugar levels and HbA1c, a measure that provides a snapshot of average blood sugar levels over the past two to three months, finds a study in the June 2016 issue of The Journal of Alternative and Complementary Medicine. (Prediabetes means your blood sugar levels are higher than they should be, but not quite high enough to be diagnosed as type 2 diabetes…yet, says the Centers for Disease Control and Prevention.)

… But don’t combine aloe vera with diabetes meds

If you have diabetes and are already taking medication to lower your blood sugar, steer clear of aloe vera juice, cautions Fraga. “Aloe vera juice can also increase insulin secretion and in large quantities, if you have diabetes, this can cause low blood sugar when you are already taking blood sugar-lowering medication,” she warns. Insulin is tasked with moving blood sugar to your cells for energy, and if there’s too much in your bloodstream, your cells absorb too much glucose (sugar) from your blood, resulting in potentially dangerous low blood sugar. And the same ingredients that add calories and taste to your aloe vera juice also add carbs, she says. Carbs cause blood sugar to rise, which is why many people with diabetes count their carbs.

You don’t need aloe vera juice for hydration 

Many aloe vera juice enthusiasts claim it is more hydrating than water, but that’s not true, warns Monica Reinagel, MS, a dietitian in Baltimore and author of several books, including Nutrition Diva’s Secrets for a Healthy Diet. “Aloe vera juice will not hydrate you any faster than regular water, and although aloe vera contains a few vitamins and antioxidants, it’s not a nutritional powerhouse. You can get these nutrients in greater quantities from much better-tasting foods.”

Drinking aloe vera juice won’t help your skin

While topical aloe vera can soothe skin, drinking aloe vera juice will not have any positive effects on your complexion, warns Adam Friedman, MD, a professor and Interim Chair of Dermatology at George Washington School of Medicine and Hospital in Washington, D.C. “There is no real evidence that I know of that suggests that ingestion of aloe vera will have any skin benefits and it can interfere with the metabolism of multiple drugs, like diabetes and heart meds which can potentially cause dangerous adverse events.”

Don’t trust aloe vera juice labels

You can’t always be sure that your chosen aloe vera drink contains everything the labels says it does, cautions Beth Kitchin, RD, PhD, an assistant professor in the Department of Nutrition Sciences at The University of Alabama at Birmingham. Just 50 percent of the aloe products tested contained what they said they did, reports Consumer Lab, an independent supplement testing group. In particular, two of five juices included in this analysis of aloe vera products failed testing, but the top picks, Lily of the Desert Aloe Vera Juice and the drinkable Lakewood Organic Pure Aloe Vera Gel, were found to be rich in acemannan, the report showed.

Watch out for hidden calories

Aloe vera juice has a slightly bitter, citrusy flavour, which means that other ingredients are often added to enhance its taste, says Fraga. “It’s not a great flavour, so many aloe vera juices are sweetened, making them more caloric,” she says. “For people who are watching their weight, aloe vera juice can have hidden calories.” Her advice? Look what else is in it before you imbibe. Ingredients like agave or honey will make aloe vera juice taste better, but can be calorie bombs.

You could control the calories by making your own: Crush an entire leaf of the plant and grind or press it to produce a liquid. This liquid can be combined with water, fruit, vegetables, juices, or natural sweeteners to improve upon its natural flavour, says the International Food Information Council, an industry-funded group. Laurion cuts one leaf into sections, peels it like she would an avocado or mango and extracts the gel with a spoon. “I mix fresh peeled aloe vera plant with apple, cucumber, pineapple, or coconut juice in a blender,” Laurion says.

The bottom line on aloe vera juice

There really isn’t any data that supports aloe juice as being beneficial for anything, says Kitchin. If you’re tempted to try a glass of aloe vera juice, ask yourself why, she suggests. “What are you trying to get out of this beverage? There aren’t any legitimate reasons to drink it. The data as it is right now just doesn’t show that aloe vera juice will give you a lot of health benefits,” she says. That said, studies are likely underway.
