The five demand categories most often briefed for Czech Republic are: (i) sleep and stress — pectin gummies, soft chews and oral strips lead, with claim wording drawn from authorised botanicals on the EU register where eligible; (ii) beauty and skin — pectin gummies are the dominant format, supported by an authorised structural-claim framework around vitamins of relevance to skin, hair and nails; (iii) energy and focus — gummies, capsules and powders for stick-packs cover the spectrum from gentle to high-active-load; (iv) immune support — pectin gummies, tablets and effervescents drawn on the established authorised-claim register; and (v) kids and family multi-vitamin — pectin gummies dominate, with claim wording reviewed at the artwork gate. On format mix: pectin-based gummies are the leading on-trend format and DAT's flagship category; soft chews are a meltable confection-style format for kids and family; capsules and softgels remain the workhorse for high-active-load and lipid-soluble formulations; oral strips are used for fast-dissolve novel-delivery SKUs; powders are used for stick-packs and tubs. Format-specific regulatory notes for Czech Republic: gummies must declare gelling-agent type (pectin vs bovine gelatin) on the ingredient list — this is a frequent rejection point on translated artwork; softgels containing fish-derived actives must declare fish as an allergen under EU FIC; oral strips and powders require accurate net-quantity declaration.
