Related Episodes for What Vitamin D Levels Can and Cannot Tell Us

“For example, while vitamin C acts primarily as an antioxidant at physiological concentrations of approximately 50 micromoles per liter, pharmacologic doses of intravenous vitamin C greater than 1 gram generate hydrogen peroxide, a type of reactive oxygen species produced by neutrophils to destroy pathogens such as viruses.”

“In a two-year trial of 237 postmenopausal women, approximately 9 to 10 grams per day combined with resistance training and walking did not add a bone-density benefit, so its role is better framed around muscle and physical function.”

“How too much iron can lead to protein aggregation and how vitamin D can prevent it. A program, directed by Gordon, called the Caenorhabditis Intervention Testing Program which tests potential longevity compounds that may extend the lifespan of several different species of worms.”

“Dr. Rhonda Patrick talks at SF Nerd Nite about transgenerational effects of caloric restriction on longevity, B-vitamins silencing bad genes, cognitive stimulation reversing neurodegenerative disease, exercise increases neurogenesis, and ways in which vitamin D might influence aging.”

“Dr. Patrick uses 4,000 IU of vitamin D as a reference point, which is also the adult tolerable upper intake level, and takes 250 milligrams of supplemental magnesium as her personal dose while emphasizing magnesium-rich foods.”

“Magnesium supports hundreds of enzyme reactions involved in functions such as energy metabolism and DNA repair, and foods including leafy greens, legumes, nuts, seeds, and whole grains can help close common intake gaps.”

“In a randomized crossover trial, a standardized ashwagandha extract produced a modest testosterone increase in overweight men with mild fatigue, while a meta-analysis of five tongkat ali trials found a positive pooled effect with substantial variation across studies.”

“In a randomized factorial design, participants were assigned to one gram per day of algae-derived omega-3 or placebo, 2,000 IU of vitamin D3 or placebo, and a 30-minute home strength program three times weekly or a flexibility control.”

“Vitamin D and a home exercise program added benefit on one clock. Separate analyses found lower odds of prefrailty and fewer invasive cancers with the full three-part intervention, making the combined healthy-aging approach a useful area for continued study.”

“Melatonin appears in the comparison as a personal, goal-specific choice rather than a universal nightly supplement. Dr. Patrick also discusses glycine, collagen, myo-inositol, and other non-overlapping items with different levels of evidence.”
