“Future work will need to test whether earlier or longer-term exercise, possibly in combination with other lifestyle strategies, can influence more stable layers of the aging epigenome and translate into meaningful gains in muscle function or resilience. In episode #62, Dr. Steve Horvath discusses epigenetic aging clocks and their use in predicting biological aging and healthspan.”

“Epigenetics is a biological mechanism that regulates gene expression (how and when certain genes are turned on or off). Diet, lifestyle, and environmental exposures can drive epigenetic changes throughout an individual's lifespan to influence aging.”

“Learn more about the health effects of beta-hydroxybutyrate in our overview article. Link to full publication. Ketogenic diet and beta-hydroxybutyrate improve gene transcription and reduce intellectual disability in inherited epigenetic machinery disorder.”

“Epigenetic changes are biological mechanisms that regulate gene expression (how and when certain genes are turned on or off). DNA methylation – the addition of methyl groups to the nucleotide bases of DNA – is a common epigenetic change.”

“Epigenetic alterations don't change the DNA sequence but how it is 'read.' In particular, DNA methylation, the addition of a methyl group (or molecule), is an epigenetic switch that can stably turn off genes, suggesting the potential to cause cancer just as a genetic mutation can.”

“The process of regulating gene expression involves epigenetic modification, the process of chemically modifying DNA structures to enhance or silence specific genes. These modifications include histone acetylation, DNA methylation, and non-coding RNAs.”

“In twin pairs where one twin was heavier than the other, the heavier twin's epigenetic age was approximately 5 months older than the lighter twin. They also found that age acceleration was associated with insulin resistance, a risk factor for type 2 diabetes.”

“Biological age is distinct from chronological age; it reflects cellular and DNA health. Regular coffee consumption significantly lowers epigenetic age markers, indicators closely tied to inflammation, metabolic processes, and aging itself.”

“Supplementing with 4,000 IU of vitamin D per day for 16 weeks reversed epigenetic aging by 1.85 years in overweight and obese African Americans that were low in vitamin D (randomized-placebo controlled trial). Epigenetic marks follow a certain pattern with age.”

“Minimal evidence suggests that people who carry mutations in the MTHFR gene (which impairs homocysteine metabolism) may benefit from creatine supplementation. Learn more about DNA methylation and its role in epigenetics in this overview article.”
