Hindi ako personally tried ng Oviral, pero marami sa circle ko ng moms ang umiinom nito for immunity, especially ngayong panahon ng ulan at sick season, kaya ang dami namin nag-ask sa pedia about it! One cap per day lang talaga ang recommended, pero honestly better pa rin kung tanungin mo yung doctor mo first para sigurado if it's the right choice for you and your family, lalo na kung may specific health concerns kayo. What's making you consider it, preventive lang or may specific reason?
