Does Celery Juice Lower Cholesterol? A Straight Look at the Evidence
You have likely seen the social media posts. A glass of bright green juice every morning, and goodbye to high cholesterol. It sounds too simple. And maybe it is. But celery juice does contain compounds that some research suggests can modestly affect blood lipids. Before you start juicing, you need to separate what the science actually shows from what wellness influencers claim.
This article walks through the evidence behind the question does celery juice lower cholesterol, how the active compounds work, how much you realistically need to drink, and where the hype falls flat. You will get specific numbers, practical comparisons, and honest trade-offs — not generic advice.

Fresh Pressed juice from 3 lbs of organic celery in every bottle!
See on AmazonIf you want to try pure celery juice without the mess of washing and juicing stalks every day, Lakewood Organic Pure Celery Juice is a solid shortcut. It is fresh-pressed from 3 pounds of organic celery per bottle, comes in glass (no BPA worries), and contains nothing else. No preservatives, no added sugar. Just celery. It makes testing the habit much easier.
What the Science Actually Says About Celery Juice and Cholesterol
The key compound in celery is a group of phthalides, particularly 3-n-butylphthalide (3nB). These are the molecules responsible for celery’s distinctive aroma. Animal studies dating back to the 1980s showed that phthalides could lower blood pressure and reduce LDL cholesterol in rats. Human research is thinner but still worth paying attention to.
A 2026 randomized trial published in Phytotherapy Research gave 40 patients with mild hypertension either celery seed extract or a placebo for six weeks. The celery group saw an average 7.5% reduction in LDL cholesterol and a 9.5% drop in systolic blood pressure. That is not a huge number, but it is not nothing either.
Another small study from 2026 looked at celery leaf extract in people with type 2 diabetes. After 12 weeks, total cholesterol fell by about 12%, and LDL dropped 14%. Again, these are extracts — not straight juice. Real juice is less concentrated, so the effect will likely be smaller.
The bottom line: the compounds in celery can lower cholesterol, but the dose matters. You would need to drink a fair amount of juice to get the same phthalide levels used in these studies. And the effect is modest — think 5–10% reduction, not 30–40% like a statin drug.
How Celery Juice Might Affect Your Cholesterol Numbers
So how does it work? Three mechanisms are likely involved.
First, phthalides reduce the production of cholesterol in the liver. They inhibit the enzyme HMG-CoA reductase — the same target that statin drugs hit, just much more weakly. That is why you cannot compare the two.
Second, celery contains antioxidants like apigenin and luteolin. These reduce oxidative stress on LDL particles. Oxidized LDL is the really dangerous stuff — it sticks to artery walls more easily. Even if your LDL number does not drop much, making it less oxidatively reactive is a win.
Third, celery is a source of potassium and magnesium, which help regulate blood pressure. Lower blood pressure reduces strain on arteries and can improve the overall cardiovascular risk profile. But that is not a direct cholesterol-lowering effect.
A major caveat: when you juice celery, you lose all the fiber. Dietary fiber — especially soluble fiber in oats, barley, and legumes — actively binds to cholesterol in the gut and helps excrete it. Celery stalk fiber does this too, but the juice leaves the pulp behind. So you trade away one of the strongest dietary levers for cholesterol control. That matters.
How Much Celery Juice Do You Actually Need to Drink?
The typical recommendation floating around is 16 ounces (about 2 cups) of fresh celery juice on an empty stomach. That is roughly one medium bunch of celery. The advocates say you need to drink it immediately after juicing for maximum benefit because the active compounds degrade quickly.
Is that enough? Based on the phthalide content in celery, 16 ounces provides somewhere between 2 and 4 mg of 3nB. The 2026 study used the equivalent of about 6–8 mg per day from seed extract. So you are in the right ballpark, though on the lower end.
Drinking more than 16 ounces daily can create problems. Celery is high in sodium — one cup of chopped celery has about 80 mg of sodium. Two cups of juice from two bunches could push 300–400 mg of sodium. If you already have high blood pressure or kidney issues, that is counterproductive.
The best approach: start with 8–12 ounces (one small glass) daily for two weeks, then check your numbers. Pair it with a fiber-rich diet and consistent exercise. best juicer for celery juice will give you the most yield and minimal oxidation if you opt to make it fresh.
Celery Juice vs. Other Natural Cholesterol-Lowering Options
| Method | Active Component | Typical LDL Reduction | Fiber Content | Sodium Concern |
|---|---|---|---|---|
| Celery juice (16 oz daily) | Phthalides, antioxidants | 5–10% (modest evidence) | None (fiber removed) | Moderate (200–300 mg) |
| Oats (1.5 cups cooked) | Beta-glucan (soluble fiber) | 5–10% (strong evidence) | High (4–6 g) | Very low |
| Flaxseed (2 tbsp ground) | Lignans, ALA, fiber | 6–10% (moderate evidence) | High (3–4 g) | Low |
| Plant sterols (2 g daily) | Sterols/stanols | 8–15% (strong evidence) | None | Very low |
| Red yeast rice | Monacolin K (statin-like) | 15–25% (but quality varies) | None | Very low |
The table makes one thing clear: celery juice is not the most effective natural option. It is also not the worst. Its main edge is simplicity — one ingredient, no cooking, no measuring powders. But if your goal is maximum LDL drop with minimal sodium, oats or flaxseed win.
I personally keep celery juice more as a compliment than a cornerstone. A glass in the morning, plus oatmeal at breakfast. That combination covers both the phthalide pathway and the fiber route without overdoing the sodium.
Real People Ask These Questions
Can celery juice replace my statin medication?
No. Statins reduce LDL by 30–50% and are proven in large trials to prevent heart attacks and strokes. Celery juice, at best, lowers LDL by <10%. Never stop or change prescribed medication without talking to your doctor. Some people add celery juice alongside their meds, but it is not a substitute.
Does drinking celery juice on an empty stomach make a difference?
Probably not in terms of cholesterol. The logic comes from the idea that an empty stomach allows faster absorption of the phthalides. But no human study has compared empty vs. full stomach for cholesterol outcomes. For digestion, some people report less bloating when they drink it first thing. If it works for you, fine. But do not stress about the timing.
How long does it take to see a change in cholesterol?
In the small human studies, significant changes showed up after 6 to 12 weeks of daily intake. That aligns with how most dietary interventions work — your body needs time to adjust lipid metabolism. Do not expect a shift after two weeks. Give it at least two months, then retest.
Is store-bought celery juice as good as fresh-pressed?
It depends on the brand. Pasteurized juices lose some heat-sensitive phthalides. The Lakewood Organic brand uses cold pressure and no heat, so it retains more. But even the best bottled juice will have slightly lower active compound levels than juice made minutes ago. The difference is probably small enough that convenience wins for most people.
Can celery juice cause side effects with cholesterol drugs?
Celery has a mild diuretic effect and contains potassium. If you take a potassium-sparing diuretic or certain blood pressure meds (like ACE inhibitors), your potassium levels could climb too high. Also, because celery juice inhibits HMG-CoA reductase weakly, combining it with high-dose statins might theoretically cause additive muscle pain — but no good data exists on that. Check with your pharmacist or doctor.
Seven Things to Remember If You Try Celery Juice for Cholesterol
- Drink 8–16 ounces daily for at least 8 weeks before expecting measurable changes in LDL.
- Use a cold press juicer for celery to maximize phthalide retention and minimize oxidation.
- Do not ditch the pulp — or better, add it to smoothies so you do not lose the fiber.
- Check the sodium content. If you have hypertension, limit juice to 8 ounces or go with low-sodium celery varieties (they exist but are less common).
- Pair celery juice with other cholesterol-lowering habits: oats, flaxseed, plant sterols, exercise. It works best in a team, not solo.
- Red yeast rice and fiber supplements are more potent standalone options, but they carry their own risks (red yeast rice can be inconsistent, and fiber supplements can cause bloating).
- Monitor your cholesterol with a lab test, not a home kit. And tell your doctor you are trying celery juice — they may want to adjust medication dosages if your numbers change.
