Has anyone ever taken this in capsule form, in dosages of 150mg up to 900 mgs daily after evening meal to soften stools and peven constipation? It is supposed to be taken along with vitmin B6. I have a severe cystocele and rectocele and hard stools need to be avoided. I have allergies to salicylate and this does not make it any easier to find something safe for me that works. Any opinions?
