Evidence Level
Artichoke extract has been extensively studied for its benefits in digestive and metabolic health. Holtmann et al. (2003) conducted a six-week, placebo-controlled, double-blind, multicenter trial involving 1800mg/day of artichoke leaf extract, which showed substantial reduction in dyspepsia symptoms. Sahebkar et al. (2018) performed a systematic review and meta-analysis of nine RCTs, confirming that artichoke extract supplementation significantly lowers total cholesterol (-17.6 mg/dL), LDL-C (-14.9 mg/dL), and triglycerides (-9.2 mg/dL). Additionally, Kirchhoff et al. (1994) provided mechanistic evidence by demonstrating increased bile secretion following artichoke extract administration, supporting its traditional use for digestive health.
The European Medicines Agency (EMA) has approved artichoke leaf extract as a traditional herbal medicinal product for the relief of digestive complaints and to support liver function. Furthermore, Shahinfar et al. (2021) conducted a systematic review and dose-response meta-analysis of 14 studies, which found that artichoke extract significantly reduced triglycerides, total cholesterol, and LDL-C levels but did not affect HDL-C. These findings highlight the consistent evidence supporting the use of artichoke extract for both digestive and lipid-lowering benefits.
Artichoke extract has also been studied in combination with other supplements. Cicero et al. (2019) conducted a three-arm, placebo-controlled, randomized clinical trial evaluating the metabolic effect of a combined nutraceutical containing artichoke extract in dyslipidemic overweight subjects. The study found that the combination significantly improved lipid profiles and reduced oxidative stress markers.
In conclusion, artichoke extract has demonstrated significant clinical benefits for digestive health and lipid metabolism, supported by multiple studies and systematic reviews. Its approval by the EMA further validates its traditional use as a herbal remedy.
