Stem Cell 100 provides Telomere Support
Recent research indicates that the ends of chromosomes (i.e. telomeres) play a key role in aging. Telomeres shorten as we age, leading to aging at the cellular level. Telomerase is the key antiaging enzyme that repairs the ends of chromosome (telomeres) by maintaining telomere length. Harvard scientists have shown that the fundamental cause of age-related health decline is linked to telomerase. Mice without telomerase prematurely age, whereas activating telomerase in these old mice brings back youthful looks and function. Many scientists believe that telomerase mediated reversal of age-related disorders may also work in humans. It has been shown that healthy diet and exercise, which lengthen life, increase telomerase activity and telomere length1. Moreover, people with shorter telomeres have higher mortality rates (P < 0.009)2, and have higher rates of Alzheimer’s3,4, cardiovascular disease5, diabetes6, and renal disease7.
Stem cells are the main class of cells in humans that have detectable telomerase activity. Unfortunately, telomerase activity in human stem cells is typically insufficient to maintain needed function with age. Stem Cell 100 increases telomerase activity in stem cells via the resveratrol analog pterostilbene, which is a major active component in Stem Cell 100. Pterostilbene is a highly potent natural analog of resveratrol with greatly improved oral adsorption and metabolic stability with better activity levels. Resveratrol has been shown to activate telomerase in human adult stem cells in independent studies8,9,10. It also activates the WRN helicase gene that repairs telomeres8, whereas low activities of the WRN gene lead to the premature aging disease known as Warner syndrome. Unfortunately, resveratrol has a 14 min half life in the body and thus is not nearly as effective as its long lasting analog pterostilbene. We have verified that pterostilbene is indeed active in stimulating telomerase.
