There are scientific publications concerning relevant probiotic role in the intestinal metabolism and absortion of several products, including isotopes. Even more, there is an important collection of papers dealing with the possibility of an intervention with prbiotic and previotic administration protocols relatied with the mesenteric linfatic system functioning enhancement. It is my beleive that this matter could be mentioned as a possible future line of research facing limitation of absortion and quelation of several isotopes regarding their chemical presentation and behavior.
