Applicable to capsules, tablets, solid drinks, oral liquids, and finished products targeting respiratory health, liver support, immune enhancement, and detoxification. Sufficient stock is maintained all year round to support bulk wholesale cooperation with flexible MOQs that fit small trial orders for new formula tests and large-volume industrial procurement.
