Dr. Rhonda Patrick explains how magnesium supports energy metabolism and DNA repair, and compares food sources with organic and oxide supplements.

Dr. Rhonda Patrick explains why vitamin D blood levels vary with metabolism, sun exposure, absorption, and supplementation.

“Aging compromises muscle strength and bone density, altering the signaling pathways that coordinate their function. These pathways involve myokines—hormone-like proteins released by muscle during exercise that help regulate metabolism, enhance muscle performance, and support bone formation.”

“There are few cells and tissues in the body that insulin doesn't affect. In addition to regulating glucose metabolism, insulin has wide-ranging anabolic effects across multiple systems. Among its many actions are: Stimulating glycogen synthesis in liver and muscle.”

“Improvements in blood sugar levels and inflammation were closely linked to better brain health outcomes, and greater intake of polyphenol-rich foods like mankai and green tea further enhanced these benefits.”

“The 10,000-step target began as a memorable way to market a Japanese pedometer, not as a biological threshold. Walking still matters because replacing sedentary time with movement supports health, and large cohort studies associate more daily steps with lower mortality.”

“Wearable-device research in more than 25,000 adults who reported no structured exercise linked about three one- to two-minute vigorous bouts per day with substantially lower all-cause, cardiovascular, and cancer mortality.”

“Circadian rhythms modulate a wide array of physiological processes, including the body’s production of hormones that regulate sleep, hunger, metabolism, and others, ultimately influencing body weight, performance, and susceptibility to disease.”

“Dr. Patrick also discusses vitamin D and potassium as nutrients that are commonly worth assessing. Vitamin D status varies with sun exposure, diet, skin pigmentation, age, and body composition, while potassium-rich foods help support blood-pressure regulation.”

“A final concern is that of a potential for increased cancer risk. Some evidence suggests that NMN supplementation or NAD+ metabolism may drive tumorigenesis, especially in the proinflammatory environment associated with senescent cells.”
