D lactate and fatigue/lethargy

    Hi everyone. I am not a ME/CFS sufferer but I feel compelled to share my experience with someone in case it is of value.

    I have experienced bouts of heavy fatigue, especially in the morning, and very unrefreshing sleep. I recently discovered that this is very likely occurring after I have a probiotic (advertised as high strength) with organisms that produce d-lactate. I found information on this site and elsewhere about the posited connection beteen d-lactate and CFS symptoms.

    Fortunately, the fatigue that I experience is transient, lifting even throughout the day, although I feel absolutely awful the whole day and more. I experienced transient diarrhea the following day, further suggesting the probiotic was the cause. Although it is transient, it is a deep lethargy/fatigue. I can imagine what it is like to have this on an ongoing basis because I suffered CFS symptoms twenty years ago for about three months. Fortunately, for whatever reason, they disappeared and didn't return.

    I am thinking about self-experimenting by taking another of these probiotics to see whether it induces the same fatigue again. I won't do so for a while, though, because the next day is just awful.

    Thank you for sharing this experience. D-lactate is a potential bad actor and probably one very good reason to avoid certain probiotics. Metametrix offers several tests that measure urinary D-lactate. One of them is the Organix Dysbiosis Profile.
