Why "Source: Prefered in bulk and organic, with make your own capsules". First, few pre-capsulized supplements are organic, most have fillers and the cost per gram as prepared capsules can be 4x to 50x higher than in bulk. Many folks have reported things did not help until they change to a different brand with different fillers.
I have seen lactobacillus rhamnosus gg (probiotics) being a TO TAKE and lactobacillus rhamnosus (probiotics) is to avoid. Why? Different studies have different results. Sometimes it is because of other factors (study done on healthy people in one case, on overweight people in the other case). One study may have measured the bacteria you are high in, the other did not. Similarly, one study may have measured the bacteria you are low in, the other did not. There is a forest of qualifications that are nearly impossibly complex to address, and if you try, it will often lack an objective decision that can be demonstrated ("I think...."). Where there are 'conflicts', my usual advice is to just omit it entirely from consideration. If you are taking it, keep taking it. It not, don't.
