“As we age, our hair changes: It often turns gray and becomes finer, and it might even fall out—permanently. There are seemingly millions of hair care products available, and many of them contain chemicals that may harm our hair or, even worse, harm our health. In this Aliquot, I explore the various ways to prevent hair loss and promote healthy hair.”

“Exercise also increased the heart's end-diastolic volume, allowing a greater stroke volume at a given filling pressure. These changes reversed measured features of sedentary cardiac aging rather than changing every aspect of biological age.”

“Resistance training is one of the most effective ways to maintain bone health. Still, other lifestyle factors, like not smoking, limiting alcohol, and ensuring that you provide your body with the nutritional components it needs for bone-building, are important too.”

“The hypothesis is that small shortfalls can permit cumulative damage over years; it does not show that one low intake measurement directly accelerates aging or that supplements reverse aging. This clip is excerpted, with permission, from Dr. Rhonda Patrick's appearance on Mayim Bialik's Breakdown.”

“Together, these pathways make the human cognitive signal biologically coherent. However, much of the direct evidence for brain uptake, neuronal signaling, and neuroinflammation comes from animal models, so it cannot establish that blueberries slow human brain aging or prevent dementia.”

“While high-intensity interval training (HIIT) might be associated with extreme, all-out efforts, at its core, it's about varying intensity levels, much like "hills and valleys." This adaptability suits many people, including older adults.”

“Boosting levels of NAD+ has been shown to improve lifespan and healthspan in animal models of premature aging and in humans. In this clip, Dr. David Sinclair describes the NAD+ salvage pathway and how boosting cellular NAD+ levels may be beneficial in slowing aging.”

“Dr. Patrick also explores possible effects on skin and brain aging. Much of this evidence comes from cells or animals, including research on oxidative damage in the aged rat brain, so these areas are best viewed as mechanistic leads rather than established oral-supplement benefits in people.”

“A 2023 network meta-analysis of 270 randomized trials found average reductions after aerobic, dynamic resistance, combined, high-intensity interval, and isometric training, with the largest pooled estimate for isometric exercise.”

“In this FoundMyFitness solo episode excerpt, Dr. Rhonda Patrick uses Dr. Bruce Ames's triage theory to explain why marginal magnesium intake may matter long before a classic deficiency appears.”
