"Contributes to reduction of tiredness and cognitive function"
These are generic EU health claims tied to trace iron content, not evidence the ashwagandha itself does this.
Consumer advice
The dose (125mg of 12:1 extract, marketed as "1500mg") is within a reasonable range for KSM-66 and this isn't a bad buy at £9.98 for 6 months. But don't expect it to boost your immune system or cognition — those bullets are legally-required generic mineral claims from the trace iron and calcium in the tablet, not from ashwagandha. If you want stress/sleep support, take it consistently for at least a month before judging results, and skip it if you're pregnant, on thyroid medication, or have liver issues.
Claims vs Evidence
MODEST0 of 5 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
