A few of us tried different things and honestly what worked varied quite a bit from person to person! Some mums in my circle really love Legendairy Milk, they have organic lactation supplements and a few swear their supply went up noticeably, though one mum did mention the taste took some getting used to. Mama's Choice Almond Powder also comes up a lot, it's quite gentle and easy to add into your daily routine, and my neighbour said it helped her quite a bit especially in the early weeks. Fenugreek supplements and soy lecithin are also popular options that some mums combine together for better results, though a small number found fenugreek made their baby a bit gassy, so just something to watch out for. Do check with your gynae or a lactation consultant though, especially since everyone's body responds differently!
