Out of 11 study participants, the leukocyte telomeres of nine participants lengthened. The leukocyte telomeres of two participants increased dramatically, moving from telomere lengths typical of 70 and 60-year-olds to those typical of people in their forties. The average telomere length of one of the 11 participants stayed the same, and one declined. Participants’ baseline average telomere length was compared to average telomere length after taking AC-11® for 12, 16 or 24 months.
