The card does not say who the 20-piece pack suits. According to the card, adults take 1–2 capsules twice a day, morning and evening after meals, for 4–6 weeks; on this regimen the pack lasts 5–10 days and the whole course needs several packs. The text of the card speaks sometimes of a tablet and sometimes of a capsule.
General information (not a manufacturer's instruction): before a course it is better to consult a doctor, as the card also recommends.
