Hi mama! B complex vitamins can range quite a bit depende sa brand, some are affordable OTC options from Mercury or Watsons na around 200-400 pesos, pero may mas premium brands din na mas maricet. A few of us mums get it from our OBs din or sa pharmacy with prescription kasi sometimes may discount, so it's worth asking your doctor where they recommend you buy it or if they have samples! Since bagong reseta lang sayo, stick with what your doc prescribed para sigurado na ang tamang dosage for you.
