“Resveratrol is a natural compound found primarily in the skin of red grapes and the root of Polygonum cuspidatum (also known as Japanese knotweed). It is also present to a lesser degree in peanuts and blueberries.”

“Anatomy of the blood-brain barrier Blood vessels throughout the body are lined with a single layer, or sheet, of endothelial cells, a specialized type of epithelial (i.e., skin-like) cell.”

“Vitamin A is important for the maturation of various cells of the innate immune system. Vitamin A deficiency can impair protective barriers such as the skin and mucosal layers, can weaken the response to vaccination, and might predispose people to respiratory infections. In this clip, Dr. Rhonda Patrick discusses how vitamin A is involved in mounting an immune response.”

“In this clip from Dr. Rhonda Patrick's appearance on The Knowledge Project, she explains why vitamin D status depends on more than food intake. UVB exposure varies with season, latitude, skin pigmentation, sunscreen use, age, and time spent outdoors.”

“Vitamin D production in skin declines with age, while omega-3 dose needs vary with baseline status, body weight, chemical form, and EPA plus DHA intake. These differences favor laboratory-guided and diet-aware decisions over one universal dose for every older adult.”

“Tight junctions connecting endothelial cells at the blood-brain barrier form much tighter junctions than those of the liver and take on a structure more similar to epithelial tissue (e.g., skin), which severely limits paracellular transport.”

“The most common signs of infection are an expanding non-painful area of redness on the skin, fever, headache, and feeling tired. When Tim Ferriss contracted Lyme disease, he drew on his familiarity with the ketogenic diet to regain his health.”

“In this clip from a conversation between Dr. Rhonda Patrick and Thomas DeLauer, she explains why body weight and appearance alone cannot reveal visceral-fat risk. Visceral fat is stored inside the abdomen around internal organs, while the fat that can be pinched beneath the skin is subcutaneous.”

“Nicotinamide, NR, NMN, oral NAD, and intravenous NAD are related but not interchangeable. Nicotinamide has separate evidence in selected high-risk skin-cancer populations, summarized in a systematic review, while NR has the more developed oral human pharmacokinetic literature discussed here.”

“In this clip from Dr. Rhonda Patrick's presentation at the Vibrant Wellness Longevity Summit, she explains how limited UVB exposure, skin pigmentation, age, and higher body fat can make low vitamin D status more likely.”
