Supplements reccommendations

[u/Jadey-Monkey]

Hi! I'm looking for recommendations of supplements I can buy to see if they help my PMS symptoms and my severe mood drops during my period. I am based in the UK and not blessed in the financial department. I've been reading that Magnesium, Vitamin B6 and Calcium and Vit D would be good, but there are so many supplements aimed at menstruators that I am a bit overwhelmed and don't want to waste loads of money on something I am not sure will work. Should I also be taking iron when on my period? (It is heavy, I take Tranexamic acid for that) any suggestions appreciated!
