“NAD+ levels are one way for energy to be circulated within the cell, and levels rise while fasting and decrease during aging. A group of enzymes called sirtuins rely on NAD+ to exert their beneficial activities, functioning less well as levels decline.”

“But new research is focused on identifying certain windows of vulnerability during a person's life when interventions might improve sleep quality and confer a kind of resilience to Alzheimer's disease, staving off the cognitive decline commonly associated with aging.”

“As people age, there's a noticeable loss of fast-twitch fibers, emphasizing the importance of strength training for older adults to counteract risks like falls and frailty. In this clip, Dr. Martin Gibala explains how vigorous activity engages both slow- and fast-twitch muscle fibers and delves into the effects of aging on these fibers.”

In this clip, Drs. Levine and Patrick discuss lifestyle factors that accelerate epigenetic aging including smoking cigarettes or having a low omega-3 index.

“Lutein and zeaxanthin also have evidence in age-related eye disease, although the AREDS2 trial did not find an additional reduction in progression to advanced macular degeneration in its primary comparison. Magnesium and creatine address different needs.”

Dr. Rhonda Patrick discusses joint aging prevention, avoiding heavy metals in protein, reducing migraines, nicotinamide for skin, and minimizing jet lag.

“Once transplanted, cells age as if they were still in the donor's body, offering promise for the idea of rejuvenation in humans. In this clip, Dr. Steve Horvath describes strategies for altering epigenetic aging with stem cells.”
