What is artichoke leaf?
This comes from the same plant as the artichoke on your plate, but from the leaves. Nobody eats those, yet they're the richest source of luteolin in the whole plant, and they also hold cynarin, the compound behind its bitter edge.
Ours is a 10:1 leaf extract, which means the leaf has been concentrated down to a tenth of its starting weight.
Artichoke also has a party trick. Two of its compounds change how your tongue reads taste for a short while, so a sip of water after eating some can taste sweet. Scientists wrote this up in the journal Science in the 1970s.
What it does
- DigestionSupports comfortable digestion after meals.
- Bile flowSupports healthy bile flow, the fluid that helps you break down fat.
- CholesterolHelps maintain cholesterol already in the healthy range.
- LiverTraditionally used to support the liver.

What people take it for
Some evidenceDigestion after mealsIn a 6-week study of 247 people with ongoing indigestion, those on the extract improved more, and rated their daily life better too.
Some evidenceCholesterolAcross 9 studies and 702 people, LDL fell by about 15 points. Those starting higher tended to see a bigger drop. HDL didn't change.
Early daysLiver enzymesIn 5 small studies of people with fatty liver, ALT and AST came down. There's still not much research.
How long it takes
In one small study, bile output rose within an hour and stayed up for a couple of hours. The rest takes longer: the main digestion study ran 6 weeks, and one cholesterol study ran 12.
- About 1 hourBile output at its highest in one small study, using a large amount given straight into the gut
- 6 weeksHow long the main digestion study ran
- About 12 weeksWhen one cholesterol study took its final reading
How long it stays in your body
It's a mix of compounds, so there's no one figure. Most peak within an hour, a second group peaks at 6 to 7 hours, and levels keep falling over 24 hours.
What's in a capsule
One capsule holds 500 mg of 10:1 extract. The digestion study used about 1,920 mg a day and one cholesterol study used 1,280 mg a day, so one capsule is less than either.
Your body rebuilds it on the way in
Here's the odd part. When researchers looked for artichoke's signature compounds in people's blood and urine, they couldn't find them at all. What they found were the pieces your gut and liver turn them into, like caffeic and ferulic acid. So those pieces may be doing much of the work.
The most direct effect is on bile, the fluid your liver makes to help you digest fat. In one small study, a large single amount, nearly four capsules' worth, was given straight into the gut. Bile output rose about 150% after an hour. A dummy treatment raised it early on too, but the extract stayed ahead at 2 to 2.5 hours. That's the likely link to its old reputation for rich, fatty meals.
It's also why it isn't for everyone. More bile is fine when the pipes are clear, and a problem when they aren't, so anyone with gallstones or a blocked bile duct needs to steer clear.
What it interacts with
- Cholesterol medicines, including statinsThe two may add together, which could change what your doctor wants to prescribe. Tell them you take it.
- Blood pressure medicinesStudies found a small drop, about 2 points on top and 1.5 on the bottom, which could add to your medicine.
- Diabetes medicinesStudies found lower fasting insulin, and in one review slightly lower blood sugar, so check that the two go together.
- Medicines in generalLong-term use and interactions haven't been studied much, so a missing warning doesn't mean it's been cleared. Ask your pharmacist.
Goes well with
Side effects
- Loose stools, stomach cramps, nausea, heartburn and gas. These may come from the extra bile.
- Most people tolerate it very well. One study put tolerability at about 96%.
Check first if
- Gallstones or a blocked bile duct: don't use it, since more bile could make things worse.
- Allergic to daisies, ragweed or thistles: artichoke belongs to the same plant family. Cross-reactions with artichoke itself are poorly documented, so ask first.
- Allergy: reports are rare, but four cases of tongue swelling and blocked airways have been described, and people who handle the plant at work can get skin rashes. Stop and get help if your tongue or throat swells.
- Pregnancy or breastfeeding: we didn't find good safety data, so check with your doctor.
- Liver disease: ask your doctor first. Lower liver numbers on a test don't replace proper care.
The blood tests that go with it
- LDL cholesterolThe number that moved most in studies.
- TriglyceridesFell by about 9 points in the same studies.
- ALTA liver enzyme that came down, mostly in people with fatty liver.
- ALPAn enzyme tied to your liver and bile ducts, which also fell in studies.
- HOMA-IRAn estimate of how hard your body works to manage sugar. It improved in a recent review, though not in an earlier one.
- Total bilirubinCan run high when bile isn't flowing freely, which is worth knowing before you start.

Questions
What is artichoke leaf extract good for?
Mostly digestion after meals and cholesterol. Studies also looked at liver enzymes, though there's less research there.
How long does artichoke leaf extract take to work?
In one small study, bile output rose within about an hour, using much more than a capsule. For digestion, the main study ran 6 weeks. For cholesterol, one study took its final reading at 12 weeks.
What are the side effects of artichoke leaf extract?
Usually mild: loose stools, cramps, nausea, heartburn and gas. Allergic reactions are rare.
Who should not take artichoke leaf extract?
Anyone with gallstones or a blocked bile duct. If you're pregnant, breastfeeding, have liver disease, are allergic to plants in the daisy family or take regular medicines, talk to your doctor first.
Does artichoke leaf extract lower cholesterol?
Studies found LDL down by about 15 points on average and total cholesterol by about 18. In one trial of otherwise healthy adults, the change was smaller: total cholesterol fell about 4%, against a 2% rise for those on a dummy capsule. It's no replacement for a statin your doctor has prescribed.
Is artichoke leaf extract good for your liver?
It has a long traditional use for this, and small studies in people with fatty liver found lower ALT and AST. That's promising, but it isn't proof of a healthier liver.
Does it help with IBS?
Possibly, but the evidence is thin. In a group of 208 adults, IBS complaints fell by about a quarter over 2 months, but nobody was given a dummy capsule to compare against.
Can I take artichoke leaf extract every day?
That's how studies gave it, for up to about 12 weeks. We know less about longer use.
Is it the same as eating artichokes?
No. The extract comes from the leaf, while the part you eat is rich in a fiber called inulin. Both are good for you in different ways, and eating artichoke is perfectly fine.
Why does water taste sweet after artichoke?
Two compounds in artichoke, cynarin and chlorogenic acid, change your taste buds for a short time. A capsule you swallow shouldn't do this, because it doesn't sit on your tongue.
