“A meta-analysis of eight studies found that higher blood concentrations of vitamin C are linearly correlated with lower all-cause mortality risk. Furthermore, research indicates that vitamin C intake of 1,000 milligrams per day nearly maximizes blood concentrations.”

“Neutrophils generate large quantities of reactive oxygen species, putting them at risk for oxidative stress-induced DNA damage. Vitamin C is highly concentrated in neutrophils, however, with concentrations averaging roughly 50 times higher than plasma concentrations.”

“Vitamin C plays a critical role in immune function. Vitamin C is highly concentrated in immune cells, where it serves as a potent antioxidant. Vitamin C also boosts the immune system by promoting the proliferation of T cells and preventing T cell death.”

“Vitamin C is concentrated in immune cells and protects immune cells from the reactive oxygen species produced during inflammation. Anecdotal data suggest that intravenous vitamin C can shorten the length of COVID-19-related hospitalization.”

“Dr. Patrick theorizes that the oxidized state of vitamin C, acting as a pro-oxidant, has the potential to kill cancer cells. Cancer cells have circumvented death; however, with a small prompt they can be induced to die.”

Dr. Rhonda Patrick answers audience questions on various health, nutrition, and science topics in this Q&A session.

“National survey analyses estimated that roughly 38% to 47% of Americans consumed less vitamin C than the Estimated Average Requirement across 1999–2018, while an earlier biomarker survey found clinical vitamin C deficiency in about 7%.”

“When considering vitamins, we tend to think of the usual suspects – A, C, D, E, and K, plus the eight B vitamins. However, the body produces many molecules that fit the description of a vitamin, driving physiological processes from infancy through later life.”

“In a controlled crossover study of eight healthy men, a high-PPO banana smoothie produced an 84% lower peak concentration of circulating flavan-3-ol metabolites than a flavan-3-ol capsule.”

“She describes five grams of L-glutamine daily as part of her personal routine while keeping the evidence focused on highly trained athletes rather than ordinary exercise. Dr. Patrick discusses vitamin C mainly as a way to support adequacy when dietary intake is low.”
