We have a customer whose colon had been removed, plus he had short bowel syndrome (where a lot of the small intestine has been removed). Needless to say, getting enough nutrients is a challenge for him. He has used Absorb Plus regularly and ongoing for about 3-4 years now.
However, what he found helped was to also take some psyllium seed powder at the same time, to slow down the transit and bulk up the liquid. Otherwise the Absorb Plus would go through his system very rapidly. He would also take some L-Glutamine on an empty stomach to further assist – but he found the psyllium worked better for him than the L-Glutamine (which makes sense since L-Glutamine’s water-absorption activity is primarily in the colon). You could try this and see how it works for you.
