Flavored Formula milk

Ano po ba ang gatas na may any flavor? Kasi breastmilk naman baby ko pero wala na talaga ako enough na gatas for her, she's already 1 year old and 3 months, she lost weight also kasi d rin sya kumakain ng maayos.. Im worried, at ano kaya mas maganda na vitamins for her age?? Please any recommendations po.. Thank you😁
