TA-65 is a dietary supplement based on an improved formulation of a small molecule telomerase activator that was discovered in a systematic screening of natural product extracts from traditional Chinese medicines. This study summarizes the findings on telomere length (TL) changes from a randomized, double blind, placebo controlled study of TA-65 over a 1 year period. The study was conducted on 97 relatively healthy cytomegalovirus-positive subjects aged 53-87 years old. Subjects taking the low dose of TA-65 (250 U) significantly increased TL over the 12 months period, as compared to the placebo group (530 ± 180 bp; p = 0.005), whereas subjects in the placebo group significantly lost TL (290 ± 100 bp; p = 0.01). The high dose of TA-65 (1000 U) showed a trend of improvements in TL compared with that of the placebo group; however, the improvements did not reach statistical significance. TL changes in the low-dose group were similar for both median and 20th percentile TLs. The findings suggest that TA-65 can lengthen telomeres in a statistically and possibly clinically significant manner.
As expected, the placebo group showed a decrease in telomere length
|Median telomere length||290 ± 100 bp|
|20th percentile telomere length||170 ± 50 bp|
While the group taking one capsule of TA-65® (250 Units) per day showed an increase in telomere length
|Median telomere length||533 ± 180 bp|
|20th percentile telomere length||270 ± 90 bp|
