Any supplements that help with OCD?

I’m no doctor but magnesium has been very helpful to me, as it promotes a calm state of mind and relaxation. There are different types too, such as Magnesium Glycinate (which I take) and Magnesium Citrate, which is the type found in “Calm” products. Both help in my experience, but Citrate may have more of a laxative effect lol.
