Ginger and artichoke extract: what the combination trials found

Unlike most artichoke pairings, this one has real trial data behind it. A standardized combination of ginger and artichoke leaf extract was tested in a 126-person, placebo-controlled trial for functional dyspepsia, and separately in an 11-person pilot study measuring gastric emptying. Both trials were run by researchers affiliated with the extract's manufacturer — a limitation worth knowing before reading the results below.

What the larger trial found

A randomized, double-blind, placebo-controlled trial gave 126 adults with functional dyspepsia two capsules a day — one before lunch, one before dinner — of the standardized ginger-artichoke combination or placebo, for 4 weeks. By day 14, the treatment group showed a significantly greater improvement on a validated symptom score than placebo, and the advantage held through the end of the study. Broken down by individual symptom, the treatment group improved significantly more than placebo on nausea, epigastric fullness, epigastric pain and bloating. The published abstract doesn't state the exact milligram amount of ginger or artichoke extract in each capsule.

What the smaller trial found

A separate crossover pilot study gave 11 healthy volunteers one capsule of the same type of combination or placebo before a standard meal, a week apart, and measured stomach area by ultrasound before and one hour after eating. The post-meal stomach area was 24% smaller with the combination than with placebo — read as faster gastric emptying — with no notable adverse effects reported. Three participants repeated the test with two capsules instead of one, and the effect looked larger, but the study wasn't sized to confirm a dose relationship with just three people.

A specific standardized product, not a DIY combination

Both trials tested one specific, patented extract combination — sold under trade names including Prodigest — at a fixed, undisclosed ratio of ginger to artichoke. Taking a separate ginger supplement and a separate artichoke supplement together, at whatever doses those products happen to use, hasn't been tested, and there's no published data on whether it would produce the same result.

What it doesn't cover

Neither trial tested this combination for SIBO, weight, or anything beyond functional dyspepsia symptoms and single-meal gastric emptying in healthy volunteers. Search terms that mention SIBO or "gut motility support" reflect marketing language built around the gastric-emptying finding, not a claim the trials themselves made or tested directly.

Questions people ask

Does ginger and artichoke extract help with SIBO?

No trial has tested this combination for SIBO specifically. The published research covered functional dyspepsia symptoms and gastric emptying after a single meal in healthy volunteers — related digestive territory, but a different question.

What is Prodigest?

It's a trade name for the patented, standardized ginger-and-artichoke-leaf-extract combination used in both published trials. Other products combining ginger and artichoke exist and aren't necessarily the same formulation or ratio.

How much ginger and artichoke extract should I take?

The two trials used two capsules a day of one specific standardized extract; the published abstracts don't give an exact milligram breakdown, which makes it hard to translate the trial dose to a different product's label. Check the specific product's own directions.

Is the combination safe?

The pilot study reported no notable adverse effects at the doses tested. The larger trial's published abstract doesn't detail its side-effect data.
