Overview
•Rare cases of idiosyncratic liver injury have been linked to ashwagandha supplementation; discontinue immediately if jaundice, dark urine, or upper abdominal pain occurs.
•Ashwagandha can raise thyroid hormone levels (T3 and T4) and should be used with caution in individuals with hyperthyroidism or those taking thyroid medications.
•May exert additive sedative effects when combined with CNS depressants, benzodiazepines, or sleep medications.
•Avoid use during pregnancy as ashwagandha has traditionally been associated with abortifacient properties at high doses.
•BioPerine inhibits CYP3A4 and P-glycoprotein, which may increase systemic exposure to certain prescription pharmaceuticals.
