Hi mama! Congrats sa pregnancy! Para sa ascorbic acid, maraming brands available sa drugstore like Ceelin, Ascorbic Acid 500mg generic brands, or kahit ang Vitamin C supplements ng Amway/Herbalife, usually 100-300 pesos per bottle depending on brand at quantity. Pero honestly, better ask your OB muna kung anong type and dose ang best para sa iyo ngayon since you're still in first trimester, kasi may specific requirements during pregnancy, some OBs prefer certain brands or dosages na safe while breastfeeding pa if you plan to. A few of us moms here swear by asking our doctors first bago bumili ng anything para sure na walang contraindications, especially with other vitamins or meds you might be taking. Enjoy your pregnancy journey!
