Study Suggests Anti-Aging Benefits Of Plasma Exchange Therapy

The New York Times (5/28, Ravindranath) reports that “some anti-aging influencers, along with a handful of scientists, believe exchanging the plasma in your blood can...help slow biological aging.” A small study examining plasma exchange for anti-aging in humans, published Tuesday in the journal Aging Cell, suggests that “those who got plasma exchange therapy over the course of a few months had lower concentrations in their blood of the biological compounds that accumulate with age, compared with a control group.” In the study, the authors “hypothesized that treatments could get less effective over time as the body adjusts to the infusions.” Many scientists still remain skeptical of plasma exchange therapy, noting its anti-aging benefits for healthy people have “never been proven” in large clinical trials.
