Are there any food or supplements that I can take to make me less appetizing to mosquito?

No. Mosquitos are attracted by heat and carbon dioxide. If you are breathing and alive, they will find you. No supplements make you less delicious to these ladies (yes, it's females that bite). Insect repellants containing deet or clothing impregnated with Permethrin reduce bites. Bed nets can be needed in areas with malaria and preventive drugs are also important.
