I have looked into Miracle-Mineral-Supplement and have thought about it but right now I'm doing too many things and don't want to add to it. But I might give it a shot at one point.
Regarding constipation, are you taking fiber and drinking a lot of water? Have you tried Oxypowder ? I'm taking that right now and it's definitely having an impact on BM frequency. But I didn't have a problem there to begin with.
I'd definitely take Chlorella and aloe vera juice if you have constipation. I'm taking chlorella for a few reasons but it's supposed to be very good for digestion and regularity. It's also reported to make some species of probiotics multiply at 4 times the normal rate. I haven't been able to find study results backing that up, unfortunately, so that assertion remains iffy for me.
