"Ashwagandha 'boosts energy & endurance' and aids muscle recovery"
Examine.com's review finds solid evidence for stress and sleep, but weak evidence for endurance or recovery in healthy adults.
Examine.com Ashwagandha research summary -
"Product doesn't list withanolide percentage"
Without a stated standardization percentage, buyers can't confirm this matches the potency used in stress and sleep studies.
Consumer advice
Ashwagandha at 600mg/day is in the range shown to help with stress and sleep in clinical trials, so this isn't a bad choice if you want to try it. Check whether the product is standardized to a specific withanolide percentage (ideally 5%) — the listing doesn't confirm this, which makes it hard to know if you're getting a clinically meaningful dose. Skip the "boosts immune health" and "enhances mental focus" claims — those are marketing embellishments not strongly backed by evidence. If you're on thyroid medication, sedatives, or are pregnant, talk to a doctor first. Cheaper generic ashwagandha extracts exist, but this one comes from a reputable, regulated UK pharmacy, which has some value for quality assurance.
