We would advise checking with your doctor as some herbs in Majka Hair Recovery may not be safe while breastfeeding—this is because they have not been studied in breastfeeding women and may transfer into breast milk at higher doses.
You may choose to start with 1-2 capsules per day if your doctor has cleared the lower dose, as herbal supplements will be in lower concentration and yes, you can take both supplements together as they have been formulated to complement each other.
