Hello, Thanks for sharing your health concern with us. Firstly, I would like to know if there is any specific cause why your wife s obstetrician put off prescribing nutritional supplements. If proper diet is taken along with folates, supplements can be postponed for a while. If you wish to start supplements, please inform your doctor of the same because no self-medication is advisable. Shelcal can be used while it is better to choose a safer preparation than Haem-up. Allow plenty of fresh fruits, vegetables and rest. Hope this helps.
