Yes, beet juice contains natural sugar, about 6 to 7 grams per 100 milliliters (roughly 3.5 ounces). That’s less than orange juice, which has nearly three times the carbohydrate content, but it’s enough to matter if you’re watching your intake. The sugar in beet juice comes almost entirely from the beets themselves, not from anything added during processing.
How Much Sugar Is in Beet Juice
A 100-milliliter serving of fresh beetroot juice contains about 6.6 grams of sugar and 30 calories. Scale that up to a full cup (roughly 240 ml), and you’re looking at about 16 grams of sugar and 72 calories. That puts it in a similar range to carrot juice and well below apple juice or orange juice, which can pack 20 to 25 grams of sugar per cup.
The sugar in beet juice is overwhelmingly sucrose. Lab analysis shows that about 90% of the carbohydrates in beetroot are sucrose, with glucose making up around 5% and fructose about 4%. This is worth knowing because sucrose breaks down into equal parts glucose and fructose during digestion, giving beet juice a different metabolic profile than, say, apple juice, which is much heavier in fructose.
Do Commercial Brands Add Extra Sugar
Most pure beet juice products on the market contain no added sugar. Brands like Lakewood Organic list only beetroot juice and a small amount of lemon juice as ingredients, with no preservatives or sweeteners. That said, some beet juice blends mix in apple juice or other fruit concentrates to improve the taste, which can significantly increase the sugar content. If this matters to you, check the ingredient list for anything beyond beets. A label that says “100% juice” can still contain added fruit juices, so look at the nutrition panel and ingredient order.
How Beet Juice Affects Blood Sugar
Whole beets have a glycemic index of 64, which is moderate. But their glycemic load, a more practical measure that accounts for the amount of carbohydrate in a real serving, is only 5. That’s very low. Juicing removes the fiber, which generally speeds up sugar absorption, so beet juice will raise blood sugar somewhat faster than eating a whole beet.
Here’s where it gets interesting, though. Beet juice is one of the richest dietary sources of nitrates, compounds your body converts into nitric oxide. Nitric oxide helps blood vessels relax and improves how your body handles glucose. One study found that drinking about 225 milliliters (just under one cup) of beet juice significantly suppressed blood sugar spikes after a meal in healthy participants. A pilot study in people with type 2 diabetes found that beet juice improved overall glucose tolerance during a test, suggesting the nitrates may partially counteract the effect of the sugar.
The research is still limited, and results aren’t unanimous. A small study of 27 people with type 2 diabetes who drank beet juice daily found no improvement in insulin resistance. So while the nitrate content may offer some metabolic benefit, it’s not a guarantee, and the sugar content still counts toward your daily intake.
Beet Juice vs. Common Fruit Juices
Beet juice sits at the lower end of the sugar spectrum compared to popular juices:
- Beet juice: ~16 g sugar per cup
- Carrot juice: ~9 g sugar per cup
- Orange juice: ~21 g sugar per cup
- Apple juice: ~24 g sugar per cup
- Grape juice: ~36 g sugar per cup
Orange juice has roughly three times the carbohydrate density of beet juice. So while beet juice isn’t sugar-free, it’s one of the lighter options if you’re comparing it to what’s typically in your fridge.
Practical Ways to Manage the Sugar
If you drink beet juice for its nitrate benefits (lower blood pressure, better exercise performance), you don’t need much. Most studies use servings between 70 and 250 milliliters. A small 70 ml “shot” of concentrated beet juice contains only about 5 grams of sugar while delivering the nitrate dose used in clinical trials. That’s less sugar than a single tablespoon of honey.
Pairing beet juice with a meal that includes protein or fat slows sugar absorption and reduces the blood sugar spike. Drinking it alongside breakfast rather than on its own makes a measurable difference. You can also dilute it with water or blend it with lower-sugar vegetables like celery or cucumber if you’re making it at home. Whole beets, roasted or steamed, retain their fiber and produce a gentler blood sugar response than juice, so that’s another option if the sugar content concerns you.
