I took GNC fenugreek for my 1st baby. Had low supply in the beginning as well. Cant really remember the limit per day (I think is 8 tablets, but you need to double confirm on this). So will take about 4 capsules after each meal. Have to take more fluids, have enough rest as well. Once you see your supply getting stable (prob a few months), then will be able to meet your baby's demand. Managed to have enough to meet my son's demand and able to total breastfeed him for 13 months.
