In Philippines, there is no specific regulation for vitamins and mineral supplements. According to FDA AO2014-0029 Rules and Regulations on the Licensing, vitamins and minerals are listed under Food Supplement/Herbal Food/Herbal Dietary Supplement category and classified under Medium Risk Food Product. Food product must follow the Bureau Circular on Updates List of Food Additives, Codex Guidelines and Philippines Dietary Reference Intakes 2015.
Maximum limit of vitamins and minerals should follow tolerable upper intake levels or upper limits per day listed in Philippines Dietary Reference Intakes (PDRI) 2015. Below is the reference of tolerable upper intake levels or upper limits per day:
