Efficacy of a dietary supplement derived from five edible plants on telomere length in Thai adults: A randomized, double‐blind, placebo‐controlled trial

Abstract

Mylife/Mylife100® is a dietary supplement consisting of black sesame seed, guava fruit, mangosteen aril, pennywort leaves, and soy protein. These edible plants contain multiple high‐potential bioactive compounds exerting various vital biological functions including antioxidants which contribute to delaying the rate of telomere shortening. Telomere length is associated with cellular aging and age‐related diseases. This study aimed to assess the efficacy of Mylife/Mylife100® on telomere length through a randomized, double‐blind placebo‐controlled trial. The trial assessed the alteration of leukocyte telomere length after 32 adults aged 50–65 years received either Mylife/Mylife100® or placebo (five capsules/day) for 8‐week supplementation. The results demonstrated a significant increase in mean telomere length from baseline (6313 bp) to the 8‐week supplementation period (6655 bp; p < 0.05) in the group receiving the product, whereas no significant change was observed in the placebo group. Additionally, the product group exhibited a significant improvement in plasma total antioxidant capacity levels compared to the placebo group (mean change, +35 vs −38; p = 0.006). This study also showed a significant correlation between telomere length and % CD4 + T cells (r = +0.325; p = 0.00003), % CD8 + T cells (r = +0.156; p = 0.048), and visceral fat (r = − 0.349; p = 0.000006). The findings suggest that consuming this dietary supplement (Mylife/Mylife100®) for 8 weeks has a positive effect on cellular aging by lengthening telomeres possible through their antioxidant capacities. Oxidative stress and cellular aging are underlying predisease mechanisms that might be alleviated by supplementing with this product.
