This is just me but .... Algin made my constipation worse, so I do the activated charcoal.
I also for some reason did muscle testing and my body did not like Algin . Algin also tested negative for me on the EAV testing so I'm not taking it at this time, but would like to when I'm more regular.
For that sharp pain....
You may want to try lying on your back with you knees to your chest to releive that sharp pain in your left side. If it goes away while doing this, it may just be gas pain.
