I would not increase your OTC without approval from your doctors. It is just good to have medical advice on OTC supplements if you are taking medications and other supplements. I am on 16 different medications and several OTC supplements.

You asked about how to prevent diarrhea. What type magnesium are you taking? Citrate can cause diarrhea in many people. It is why a lot of doctors will recommend Glycinate as does not cause this. I do not have a problem taking Citrate. However, I split the type and take 200 mg of Citrate and 200 mg of Glycinate.

I read on many medical institutions the various forms of magnesium have specific added benefits. The Citrate is overall good for the PVCs, PACs, etc. but the Taurine is good for tachycardia, and Citrate is good for them (PACs, PVCs,) but also helps with digestion. I may add the taurine also and lower my citrate intake.

I want to pass on that every OTC I take is with the approval of my doctors. I do not take anything without their approval. I learned a lot by not doing so you could be doing yourself harm and not know it. Many things aggravate a condition, contradict a medications, or interfere with absorption etc. One of the main OTC is grapefruit. An OTC or eating it. My doctors say can really cause a higher degree of some medications therapeutics.
