One of the leading theories of aging is the telomere theory. Telomeres are protective caps at the end of your chromosomes. As cells replicate, telomeres get shorter, counting down to the cell’s death. Shrinking telomere length is associated with age and age related diseases, including cancer and cardiovascular disease.
This double-blind study found that a herbal supplement based on astragalus taken for 6 months led to significantly longer telomeres with fewer short telomeres than placebo. The supplement also included olive fruit extract, zinc and grape seed extract.
This study confirms that an astragalus based supplement actually significantly lengthens telomeres.
