Postpartum hair loss is very common and completely normal at four months. While you want to support your hair health, taking hair multivitamin gummies alongside Neurobion Forte and calcium might lead to an excessive intake of certain vitamins, particularly B vitamins. High doses of some vitamins can pass into breast milk and may not be safe for your baby. I recommend sharing the specific ingredients of your gummies with your doctor before starting them. For now, continuing your calcium and Neurobion Forte (which contains vitamins B1, B6, and B12) is a safe and excellent foundation for your recovery.
