LiverSmart combines a proprietary blend of 5 liver supporting ingredients with a standardized European milk thistle fruit extract. The milk thistle has been hand-picked to contain the optimum level and ratio of the six key liver-supporting silymarin isomers (the active ingredients within milk thistle). Agronomists (soil management and crop production scientists) manually select ‘elite seeds for the milk thistle in LiverSmart to obtain a consistent and reliable range of the key silymarin isomers (silybin A and B silychristin silydianin isosilybin A and B). The milk thistle in LiverSmart is cultivated under strict Good Agricultural (GAP) Certification in 5 European countries: Germany Spain Austria France and Czech Republic. Strict soil environmental harvesting drying pressing and cooling conditions are enforced to protect the important silymarin isomers. LiverSmart also contains five other key ingredients to support liver function - dandelion root extract artichoke leaf extract yellow dock root protease and beet root.
