Celery juice is the pressed and strained juice of celery stalks, popularized on social media around 2018 and 2019 with claims about gut health, skin, liver support and weight. Celery itself is a low-calorie vegetable that supplies vitamin K, potassium and folate, according to USDA data. But we found no randomized human trials testing celery juice for any of the popular claims, so its benefits rest on the nutrients in celery rather than on juice-specific research. Below is the celery juice nutrition picture, what the evidence actually covers, and the celery juice side effects worth knowing: sodium, vitamin K, allergy and sun sensitivity.
Peptide Labs does not sell celery juice or celery products. This article is general nutrition information, not medical advice.
Key Takeaways
- A cup of chopped raw celery has about 14 calories, 1.6 grams of fiber and 25% of the Daily Value for vitamin K in USDA data.
- Juicing strains out much of the fiber and packs several cups of stalks into one glass.
- A search of the medical literature found no randomized human trials of celery juice for the popular claims.
- Celery contains psoralens; case reports describe severe sunburn-like reactions after eating celery root before tanning.
- Warfarin users, people on low-sodium diets and people with celery allergy should take extra care.
Celery juice nutrition: what is in celery
USDA FoodData Central has no separate entry for celery juice in its SR Legacy database, so the table shows raw celery (FDC 169988), one cup chopped (101 grams), with percent Daily Values (%DV) based on FDA label values. Juice made from celery keeps much of the water, minerals and vitamin K but loses much of the pulp, where most of the fiber sits, and a glass usually takes several cups of stalks.
| Nutrient (raw celery) | Per 1 cup chopped (101 g) | % Daily Value |
|---|---|---|
| Calories | 14 | Not applicable |
| Water | 96 g | Not applicable |
| Carbohydrate | 3.0 g | 1% |
| Fiber | 1.6 g | 6% |
| Sugars | 1.4 g | Not set for total sugars |
| Vitamin K | Not shown (see %DV) | 25% |
| Folate | Not shown (see %DV) | 9% |
| Potassium | 263 milligrams | 6% |
| Sodium | 81 milligrams | 4% |
| Calcium | 40 milligrams | 3% |
| Vitamin C | 3.1 milligrams | 3% |
Celery is mostly water, which is why a large stalk has only about 9 calories (our guide to low-calorie food myths explains why it still adds a few). Its most notable nutrient is vitamin K, at about a quarter of the Daily Value per cup. It is also one of the saltier vegetables, with about 81 milligrams of sodium per cup, a modest amount on its own but one that multiplies when several cups go into a single glass of juice. Celery is a minor fiber source as a whole vegetable and a smaller one as juice; for real fiber, see our high-fiber foods list and our guide to daily fiber needs.
Celery juice benefits: what the evidence covers
Popular celery juice benefits include claims that it heals the gut, clears skin, flushes the liver, lowers blood pressure and melts weight. When we searched the Europe PMC database of biomedical literature in October 2026, we found no randomized human trials of celery juice itself for any of those outcomes. What does exist falls into three groups:
- Nutrient facts: celery supplies vitamin K, potassium, folate and water, which are real but modest contributions to a diet.
- Lab and animal studies of celery compounds: researchers have studied plant compounds in celery and celery seed extracts, mostly in cells and animals. These do not show what a glass of juice does in people.
- Celery seed products: some supplements use celery seed extract, a different plant part with a different chemical makeup. Results for seed extracts should not be applied to juice.
So is celery juice good for you? It can be a hydrating, low-calorie drink that adds some vitamin K and potassium. There is no good evidence that it does more than that, and it is not a substitute for vegetables with their fiber intact or for medical care. If you are drinking it hoping to fix bloating, see our guide on easing bloating; claims about “flushing” the liver are covered in our review of liver cleanse products.
The nitrate connection
Celery is naturally rich in nitrate, which is why celery powder and celery juice are used in place of synthetic curing salts in some bacon, ham and hot dogs. In a December 2020 letter, the USDA Food Safety and Inspection Service said it intends to propose rules barring “Uncured” and “No Nitrate or Nitrite Added” claims on meats processed with any nitrate source, including celery powder. For research on dietary nitrate from vegetables, see our beetroot guide.
Celery juice side effects and who should be careful
Celery is a common food, and moderate amounts are fine for most people. Concentrating many stalks into one daily glass raises a few specific issues.
- Warfarin and vitamin K: celery is a meaningful vitamin K source. NIH advises people on warfarin to keep vitamin K intake consistent, so starting or stopping a daily celery juice habit is worth mentioning to the clinician who manages your blood thinner.
- Sodium: several cups of celery add up. People told to limit sodium for blood pressure, heart failure or kidney disease should count it.
- Potassium and kidney disease: celery juice adds potassium; people with chronic kidney disease should ask their care team, as our potassium guide explains.
- Celery allergy: celery can trigger allergic reactions, sometimes severe. It is one of the 14 allergens EU law requires labels to highlight, though it is not on the US major allergen list.
- Loose stools and gas: some people report digestive upset when they start drinking large glasses of any vegetable juice.
Celery and sun sensitivity
Celery contains psoralens (furanocoumarins), natural compounds that make skin more sensitive to ultraviolet light. In a 1990 case report in Archives of Dermatology, a 65-year-old woman developed a severe, body-wide burn after visiting a tanning salon about an hour after eating a large amount of celery root; testing found the psoralens methoxsalen and 5-methoxypsoralen in similar celery root. A 2016 British Journal of Dermatology report described a phototoxic rash linked to a celery diet, and other reports describe stronger reactions in people eating celery during light therapy with psoralen drugs. These are rare, but if you use tanning beds, receive phototherapy or take light-sensitizing medicines, a daily celery juice habit is worth raising with your dermatologist.
Celery juice vs eating celery
| Question | Whole celery | Celery juice |
|---|---|---|
| Fiber | 1.6 g per cup in USDA data | Much of it strained out |
| Volume of celery | One cup is easy to eat | A glass usually takes several cups |
| Sodium and potassium | Modest per serving | Higher per glass, scaled to the celery used |
| Vitamin K | About 25% DV per cup | Higher per glass; matters for warfarin users |
| Human trials for health claims | None for the popular claims | None found |
If you enjoy it, celery juice can sit alongside a varied diet. If your goal is nutrition per bite, eating celery with its fiber, along with other vegetables, gives you more. People eating less on GLP-1 medicines may find that low-calorie juices crowd out protein; our GLP-1 diet guide covers priorities. For a juice with more research behind its main claim, compare our sibling guide to prune juice.
Frequently Asked Questions
What are the claimed celery juice benefits?
Claims include gut, skin, liver and weight effects. We found no randomized human trials of celery juice for these claims; its documented value is the vitamin K, potassium and water in celery.
Is celery juice good for you?
It is a low-calorie drink with some vitamin K and potassium. There is no good evidence that it does more than other vegetables, and juicing removes much of the fiber.
What are the side effects of celery juice?
Possible issues include digestive upset, extra sodium, a vitamin K load that matters for warfarin users, allergic reactions and, rarely, sun sensitivity from psoralens.
Can celery juice interact with medicines?
Its vitamin K can affect warfarin, and its psoralens may add to light-sensitizing drugs. Ask your clinician or pharmacist.
Does celery juice help with weight loss?
No trials show that. It is low in calories, but it does not change metabolism on its own.
Is celery juice better than eating celery?
Not nutritionally. Whole celery keeps its fiber, and a glass of juice concentrates sodium, potassium and vitamin K from several cups of stalks.
