Fenugreek does not work for someone who has thyroid problems. The lactation consultant and Logan regional are not super knowledgeable about specific things like that. I had my son there 7 months ago and after 100s of hours researching supplements and physically taking them. Due to a lot of different things, I have to exclusively pump. But I am 100% positive that both blessed thistle and fenugreek actually LOWER your milk supply if you have a thyroid problem.
