A single 240 ml glass delivers around 60% of your daily vitamin K for almost no calories, plus smaller amounts of folate, potassium, vitamin C, and antioxidants such as apigenin and luteolin. Early lab research links those compounds to lower inflammation, though the boldest claims, including curing chronic illness, have not held up in peer-reviewed human trials.
This guide covers what a glass actually contains, the side effects worth knowing, how to make it at home, and how celery juice fits into a balanced routine if you decide to drink it.
The Rise of Celery Juice as a Daily Wellness Ritual
Around 2015, Anthony William, widely known as the Medical Medium, began telling followers that drinking roughly 480 ml of plain celery juice on an empty stomach each morning could “rebuild” health from the gut outward. The practice spread through Instagram, podcast circuits, and celebrity posts, and within five years it had become a fixture of the morning routine for millions of people.
What made the trend unusual is the gap between how celery had always been used and how it was now being consumed. Celery has long appeared in soups, stews, salads, and as a crunchy snack with dip, valued mostly for texture and a subtle salt-like flavor. The new ritual stripped the stalks down to a single daily drink, often made from an entire head of celery, with no other ingredients. That shift turned a familiar vegetable into something closer to a supplement, and it pushed the conversation from cooking into health culture.
Why the Hype Split from the Nutrition
The same qualities that fueled the trend, simplicity, ritual, and a single hero ingredient, also made it easy to overstate what celery juice can do. Whole celery already contains most of the compounds people were praising in the juice, plus fiber that slows digestion and helps with fullness. The juice version concentrates hydration and a few micronutrients, but it leaves the fiber behind. Understanding that trade-off is the starting point for sorting the realistic perks from the marketing.
That missing fiber is exactly where the nutritional picture starts to get interesting.
What Celery Juice Actually Contains Nutritionally
Celery (Apium graveolens) is about 95% water, which is why a 100 g serving clocks in at only 14 calories. The remaining 5% carries a small but interesting package of vitamins, minerals, and plant compounds, and a juiced version concentrates that into a low-calorie liquid that fits easily into a morning routine.
Micronutrients in a Typical 240 ml Glass
Most published nutrition data for celery is based on whole stalks, and juicing shifts the profile by removing fiber. The numbers below come from USDA food data for whole celery, recalculated for a roughly 240 ml juice serving (about one large cup, made from one medium head).
| Nutrient | Amount per 240 ml juice | Approximate % of Daily Value |
|---|---|---|
| Calories | 33–40 | ~2% |
| Vitamin K | 56–70 mcg | ~60% |
| Folate | 35–45 mcg | ~10% |
| Potassium | 260–500 mg | ~10% |
| Vitamin C | 6–8 mg | ~8% |
| Sodium | 80–160 mg | ~7% |
| Magnesium | 12–25 mg | ~4% |
Vitamin K is the standout. A single glass covers more than half of an average adult’s daily need, which matters for blood clotting and bone health, but also explains why the drink can clash with certain medications (more on that below).
Bioactive Compounds Worth Knowing
Beyond vitamins, celery contains a small group of plant chemicals that early lab and animal studies have flagged as potentially useful:
- Apigenin, a flavonoid studied for anti-inflammatory effects on overactive immune cells.
- Luteolin, another flavonoid linked in rodent research to reduced oxidative stress in the brain.
- Phthalides, compounds that may help relax blood vessel walls, one proposed mechanism behind celery’s modest blood pressure effects.
- Coumarins, natural antioxidants being explored for their role in circulation and inflammation.
These compounds are promising in early research, but most of the evidence so far comes from test-tube or animal studies, not large human trials on celery juice itself.
What Juicing Changes
Running celery through a juicer separates the liquid from the roughly 1.6 g of fiber in a 100 g serving. That fiber loss matters because it slows how quickly sugars and plant compounds hit your bloodstream, and it feeds the gut bacteria that keep digestion regular. Drinking the juice gives you a quick hydration hit and the same phytochemicals, but without the fiber-driven satiety or the slower nutrient release that comes with chewing the stalks.
Stripped of that fiber, the question becomes whether what’s left actually does what the wellness crowd says it does.
Evidence-Based Benefits and Where the Claims Fall Short
The real celery juice benefits are a mix of modest wins, like better hydration and a vitamin K boost, and a larger pile of claims that have not been backed by solid clinical research. Sorting the two is the most useful thing you can do before deciding whether to make it part of your morning.
What the Research Actually Supports
- Hydration support. Because celery juice is mostly water with a small amount of electrolytes, including potassium and sodium, it can contribute to daily fluid intake, especially for people who struggle to drink plain water.
- Antioxidant intake. The flavonoids apigenin and luteolin have shown antioxidant activity in lab studies, which may help your body manage everyday oxidative stress from exercise, sleep loss, or pollution.
- Modest blood pressure effects. Small human studies on celery seed extract, not juice specifically, have shown a mild reduction in blood pressure, likely tied to phthalides relaxing blood vessel walls.
- Anti-inflammatory potential. Celery seed and leaf extracts have reduced markers of inflammation in animal studies, but the same effect has not been clearly demonstrated for plain celery juice in humans.
Where the Claims Fall Short
The Medical Medium has promoted celery juice as a tool to address autoimmune disease, thyroid problems, eczema, brain fog, and “toxic” liver buildup. Those claims have no published peer-reviewed clinical trials behind them. A 2020 review in the Journal of Evidence-Based Integrative Medicine, and a Harvard Medical School publication that same year, both pointed out that the strongest claims are not supported by rigorous human data, and that much of the rest can be explained by the placebo effect, increased water intake, and the simple act of paying attention to your diet.
If the benefits are mostly attributable to hydration and the placebo response, the risks deserve equal scrutiny.
If a drink is being sold as a cure for a serious condition, the burden of proof sits with the seller, and that proof is currently missing for celery juice.
Side Effects, Medication Interactions, and Who Should Be Cautious
Even though celery juice is just a vegetable in a glass, the same compounds that make it interesting can create real problems for some people. Before you build a daily habit, run through the risks below and check in with a clinician if any of them apply to your situation.
Medication and Health Interactions
- Blood thinners like warfarin. The high vitamin K content can interfere with how warfarin works, because the medication is designed to block vitamin K’s role in clotting. A sudden daily glass of celery juice can swing your INR readings.
- Kidney stones. Celery is high in oxalates, the same compounds found in spinach and almonds. People with a history of calcium oxalate stones may want to limit large daily servings.
- Thyroid medication. Celery contains natural goitrogens in small amounts, and timing matters if you take levothyroxine, since fiber and certain plant compounds can reduce absorption.
- Blood pressure medication. Combined with celery’s mild blood-pressure-lowering effect, daily juice plus medication can occasionally drop blood pressure too far, especially in older adults.
Common, Less Serious Reactions
Daily celery juice can cause bloating, gas, or loose stools in the first week, especially if you jump straight into 480 ml on an empty stomach. Some people notice a temporary spike in thirst or a mild headache as the body adjusts to more potassium and water. People with celery or birch pollen allergies can also react to the drink, since raw celery contains proteins similar to pollen allergens.
Heads up: if you take any daily medication, especially a blood thinner, blood pressure pill, or thyroid drug, check with your prescribing clinician before making celery juice a habit.
Who Should Talk to a Doctor First
Pregnant or nursing people, anyone with chronic kidney disease, a history of kidney stones, or an active eating disorder, and people on prescription medications should bring celery juice up with their healthcare team before adopting it as a daily ritual. The drink is not dangerous in normal amounts for most healthy adults, but “natural” is not the same as “risk-free,” and the concentrated vitamin K, oxalate, and potassium load deserves a quick check-in for vulnerable groups.
Preparing Celery Juice at Home and Choosing a Sensible Daily Amount
Store-bought celery juice often comes with added fruit, sugar, or “natural flavors” that change the nutrition profile, and a 350 ml bottle can carry 10–20 g of sugar without you noticing. Juicing at home keeps the ingredient list to one item, which is the point of the ritual for most people.
Step-by-Step Method
- Wash a full head of celery. Roughly 8–10 stalks make about 240–480 ml of juice. Trim off the leafy tops or save them for soup stock.
- Run through a juicer. Cold-pressed masticating juicers preserve more of the heat-sensitive flavonoids than high-speed centrifugal models, but any clean juicer works.
- Use a blender instead. Roughly chop the stalks, blend with 60–120 ml of water, then strain through a nut milk bag or fine mesh sieve to remove the pulp.
- Drink right away. Celery juice oxidizes quickly, so the vitamin C and a few flavonoids start to drop within 30–60 minutes of juicing.
Serving Size and Timing
Published celery juice recipes range from 240 ml to 480 ml per day, with 240 ml being a common starting point. Begin with a smaller glass for the first week, especially if you have a sensitive stomach, and build up only if your digestion tolerates it. Most enthusiasts drink it on an empty stomach first thing in the morning, but there is no clinical evidence that empty-stomach timing is necessary, and people with reflux or IBS often do better splitting the serving or having it with food.
Optional Add-Ins That Shift the Nutrition
Plain celery juice is the form used in most of the popular claims, but small additions can improve flavor and contribute their own nutrients:
- Lemon juice (½ lemon), adds vitamin C and a brighter flavor without meaningful calories.
- Fresh ginger (2.5 cm knob), brings mild anti-nausea and digestion-supporting compounds.
- Green apple (½ fruit), sweetens naturally and adds about 5 g of sugar per serving.
- Cucumber (½ medium), lightens the flavor and stretches the volume for very low extra calories.
Each addition moves the drink further from “plain celery juice” and closer to a mixed green juice, so the popular claims tied to celery alone apply less if you blend in a lot of fruit or other vegetables.
Putting Celery Juice in the Context of a Balanced Diet
Celery juice is one option among many, and how it stacks up against whole celery, other green juices, and the rest of your diet is the real question that decides whether it earns a spot in your morning.
Celery Juice vs Whole Celery
| Factor | Celery Juice (240 ml) | Whole Celery (100 g, ~2 stalks) |
|---|---|---|
| Calories | ~35 | ~14 |
| Fiber | ~0 g | ~1.6 g |
| Vitamin K | ~60% DV | ~30% DV |
| Hydration boost | Higher (more water by volume) | Moderate |
| Satiety | Low | Higher from chewing and fiber |
| Prep time | 5–10 min | None |
Whole celery delivers nearly the same vitamins and the same flavonoids, but the fiber changes the experience: it slows absorption, feeds gut bacteria, and adds a crunch that satisfies hunger. If your goal is hydration and a vitamin K bump, juice is fine. If your goal is a satisfying snack that supports gut health and weight management, whole stalks are the better tool.
How It Compares to Other Popular Green Juices
Cucumber juice is even more water-dilute and lower in sugar, but also lower in vitamin K. Kale-and-spinach blends deliver far more vitamin A, vitamin C, and iron, but they come with stronger flavors and higher oxalate loads. Wheatgrass shots are concentrated and small, but they can spike blood sugar in some people and lack fiber. Celery juice lands in the middle: more substantial than cucumber water, gentler than kale, and easier on the gut than wheatgrass, which is probably why it spread so widely.
Use It as a Component, Not the Center
Celery juice works best when it sits next to a varied diet, not in place of it. Pair it with a protein-rich breakfast, use it as a midday hydration swap, or build it into a smoothie with fruit and protein powder. The vitamin K and potassium become useful additions rather than redundant concentrates.
Quick Checklist Before You Commit
- Your goal. Hydration and a vitamin K boost? Juice works. Eat the stalks.
- Your medications. Blood thinners, thyroid pills, and BP meds all warrant a clinician check-in.
- Your digestion. Start at 240 ml, not 480 ml, especially on an empty stomach.
- Your schedule. Fresh juice takes 5–10 minutes, and it oxidizes within an hour, so plan accordingly.
- Your diet overall. Juice adds value when your meals already cover protein, fiber, and healthy fats.
The Bottom Line
Celery juice is a hydrating, low-calorie drink with a respectable amount of vitamin K and a few flavonoids worth paying attention to, but it is not medicine, not a detox, and not a cure. Treat it the way you would treat any single food: a useful addition on the right morning, not the foundation of a health plan.
FAQ
What are the real health benefits of drinking celery juice?
The strongest real benefits are hydration, a meaningful boost in vitamin K, and a small contribution of folate, potassium, and antioxidants like apigenin and luteolin. Beyond that, the clinical evidence is thin, and most disease-curing claims tied to celery juice have not been supported by peer-reviewed research.
Does celery juice have any negative side effects?
Yes. Common reactions include bloating, gas, and loose stools, especially when you drink a full 480 ml on an empty stomach. Celery juice can also interfere with blood thinners because of its vitamin K content, and its oxalates may raise kidney stone risk in people who are already prone to them.
How much celery juice should you drink per day?
Most published recipes suggest 240 to 480 ml per day. Start with 240 ml for the first week to see how your digestion responds, then increase only if you feel good. Larger amounts do not add proportional benefits and can make digestive symptoms more likely.
Is it better to drink celery juice on an empty stomach?
Empty-stomach timing is a tradition from the Medical Medium community, but no clinical evidence shows it is more effective than drinking it with a meal. People with reflux, IBS, or a sensitive stomach often tolerate a smaller serving with food better.
Can celery juice help with bloating and digestion?
It can help some people, mostly through the hydration and the small dose of potassium and natural sodium. The juice itself contains no fiber, so it is not the same as eating whole celery for gut health, and in some people the sudden morning volume makes bloating worse before it gets better.
What nutrients are in celery juice?
A 240 ml glass typically delivers around 30–40 calories, 60% of your daily vitamin K, about 10% of your daily folate and potassium, smaller amounts of vitamin C and magnesium, plus plant compounds like apigenin, luteolin, phthalides, and coumarins. The fiber from the original stalks is left behind during juicing.
