POM Wonderful pomegranate juice does offer real health benefits, but it comes with a significant sugar tradeoff. An 8-ounce glass packs 160 calories and about 34 grams of sugar, which is more than a same-sized glass of orange juice or apple juice. The antioxidants in pomegranate juice are genuinely powerful, with measurable effects on blood pressure, inflammation, and possibly memory. Whether it’s “good for you” depends on how much you drink and what you’re comparing it to.
What Makes Pomegranate Juice Stand Out
Pomegranate juice is unusually rich in plant compounds that neutralize harmful molecules called free radicals. The key players are a group of tannins (particularly one called punicalin) and pigment compounds that give the juice its deep red color. Punicalin has stronger radical-scavenging activity than vitamin C, and these compounds work together to reduce oxidative stress in your cells.
This isn’t just theoretical. Pomegranate juice has tested higher in antioxidant capacity than red wine, green tea, blueberry juice, and cranberry juice. What’s interesting is that pomegranate actually contains fewer pigment compounds than fruits like elderberry or blueberry, but its tannins more than compensate, making the total antioxidant package unusually potent.
Blood Pressure and Heart Health
The cardiovascular evidence is some of the strongest in pomegranate research. A meta-analysis pooling results from multiple clinical trials found that pomegranate consumption reduced systolic blood pressure (the top number) by about 8 points and diastolic pressure (the bottom number) by about 3 points. For context, that systolic drop is comparable to what some people achieve with lifestyle changes like cutting sodium or starting a walking routine.
In one trial, drinking about 7 ounces per day for six weeks lowered blood pressure in people with type 2 diabetes. The mechanism likely involves the juice’s effect on oxidative stress in blood vessels, which helps them relax and widen.
Effects on Blood Sugar and Inflammation
Despite its high sugar content, pomegranate juice doesn’t seem to worsen blood sugar control, and it may modestly improve it. A large meta-analysis of randomized controlled trials found that pomegranate consumption reduced fasting blood sugar by about 3 mg/dL compared to placebo. The benefit was most pronounced in people under 50 with type 2 diabetes and a BMI over 30. Doses under about one cup per day were effective.
The anti-inflammatory results are more striking. In a 12-week trial of patients with type 2 diabetes, those drinking pomegranate juice saw a 32% drop in C-reactive protein (a key marker of inflammation in the blood) and a 30% drop in another inflammatory marker called interleukin-6. The placebo group showed no such changes. Chronic inflammation is linked to heart disease, diabetes complications, and many other conditions, so this reduction is meaningful.
Memory and Brain Health
A year-long randomized study tested daily pomegranate juice in middle-aged and older adults. The juice group maintained their ability to learn and recall visual information over 12 months, while the placebo group showed a significant decline. The difference between groups was moderate in size. Other memory measures didn’t show significant differences, so pomegranate juice isn’t a memory booster so much as it may slow age-related decline in certain types of visual learning.
The Sugar Problem
Here’s where the picture gets complicated. POM Wonderful contains roughly 60 grams of sugar per 12-ounce bottle. That’s more than orange juice (41 grams per 12 ounces) and close to grape juice (63 grams), according to a Harvard School of Public Health comparison. For reference, the American Heart Association recommends no more than 25 to 36 grams of added sugar per day, and while juice sugar is naturally occurring, your body processes it similarly.
An 8-ounce serving, which is the standard size of the small POM bottles, contains about 34 grams of sugar. That’s already a full day’s worth of sugar for many people watching their intake. If you’re drinking it for the health benefits, keeping your portion to about 4 to 7 ounces daily gives you most of the antioxidant benefit with less sugar load. You could also dilute it with water or sparkling water.
Who Should Be Careful
Pomegranate juice can interact with certain medications by affecting how your liver processes drugs. The most important interaction is with warfarin (a blood thinner). Pomegranate juice can increase warfarin’s blood-thinning effect, raising the risk of bleeding. Observational reports have also noted prolonged effects of sildenafil (Viagra) when taken with pomegranate juice.
Other medications that may be affected include certain anti-anxiety drugs, calcium channel blockers used for high blood pressure, and some antiseizure medications. If you take prescription medications regularly, it’s worth checking whether pomegranate juice could change how your body absorbs them. The interaction works similarly to grapefruit juice, so if your pharmacist has warned you about grapefruit, pomegranate likely applies too.
How Much to Drink
Most of the clinical trials showing benefits used between 7 and 8 ounces per day. That’s the small POM bottle you’d find at a grocery checkout. Sticking to one serving daily gives you the antioxidant and anti-inflammatory benefits while keeping sugar intake manageable. Drinking more doesn’t appear to multiply the benefits, and it significantly increases your sugar and calorie load.
If you’re choosing between eating whole pomegranate seeds and drinking the juice, the seeds have less sugar per serving (about 20 grams for half a pomegranate) and add fiber, which slows sugar absorption. The juice concentrates both the beneficial compounds and the sugar, so it’s a more efficient delivery system for antioxidants but a less forgiving one for your blood sugar.
