“Increased expression of PPAR-a. Improved markers of liver health and cholesterol. Related: studies in humans have shown reduced vitamin C status directly impacts fat oxidation in response to exercise.”

“01:43:04 - Vitamins and minerals are essential for preventing disease and may have little benefit in severely ill people. 01:46:28 - Overview of SELECT, the selenium and vitamin E prostate cancer study. Study.”

“Influence insulin sensitivity. Alter estrogen synthesis. Interestingly, the Selenium and Vitamin E Cancer Prevention Trial (SELECT) reported that higher plasma omega-3 fatty concentrations were associated with an increased risk of developing prostate cancer.”

“Since ultraviolet light is required for vitamin D synthesis, reduced exposure to the sun or having dark-colored skin impairs vitamin D production. Approximately 70 percent of people living in the United States are vitamin D insufficient and ~30 percent are deficient.”

“1, 2 00:39:49 - Daily or weekly supplementation of vitamin D reduced the risk of acute respiratory infection by more than 50% in people with the lowest baseline vitamin D levels. People with higher baseline vitamin D levels also benefited, although the effect was more modest (10 percent risk reduction).”

“Two other NAD+ precursors, nicotinic acid (NA) and nicotinamide (NAM, also called niacinamide), along with nicotinamide riboside, are often collectively referred to as niacin (vitamin B3) or niacin equivalents.”

“In the control group, which did NOT have their brain aging normalized by vitamins, the brain deterioration included >50% losses of neurons, 36% loss in brain mass and a 2-fold reduction in metabolism and blood flow. Pretty gnarly, right?”

“Vitamin D activates the innate immune system, which elicits an early antiviral response. The vitamin binds to receptors on neutrophils, macrophages, and natural killer cells and stimulates them to produce microbial peptides that have antiviral activity.”

“Decaffeination can cause minor reductions in water-soluble compounds like trigonelline, a precursor to niacin (vitamin B3). This reduction typically ranges around 10–20%, but given that coffee isn't a major niacin source, this difference is negligible nutritionally.”

“NAD+ can also be synthesized from other precursors including nicotinamide (NAM, also called niacinamide), nicotinic acid (NA), and nicotinamide riboside (NR), which are often collectively referred to as niacin (vitamin B3) or niacin equivalents.”
