“Since then, countless studies have tested Pauling's theories about vitamin C, colds, and cancer (and many others), and a substantial body of evidence has emerged, identifying critical roles for vitamin C in immune function, cardiovascular and respiratory health, cognitive development and preservation, and many other aspects of human health.”

“A national survey analysis estimated 2.6% severe deficiency, 22% moderate deficiency, and 40.9% insufficiency among US adults, although prevalence changes with the threshold used. These categories should remain distinct because insufficiency is not the same as clinical deficiency.”

“A 12-month randomized controlled trial found that vitamin D supplementation improved cognitive function, intelligence quotient scores, telomere length, and lowered oxidative stress markers in older adults with mild cognitive impairment (compared to placebo), suggesting that not only does vitamin D supplementation improve biomarkers of aging, but also functional outcomes.”

“A 2025 meta-analysis found improved quality of life, no clear overall change in ejection fraction, and a borderline improvement in New York Heart Association functional class across a small set of trials.”

“The findings support working on several modifiable factors together, while leaving open how much each component contributes and whether these changes prevent an eventual Alzheimer's diagnosis.”

“Red yeast rice lowers LDL through monacolin K, which is chemically identical to lovastatin, so it shares statin-related mechanisms and requires attention to potency, contamination, medicine interactions, and muscle or liver effects.”

“The trial found selected changes in antioxidant capacity, immune-cell apoptosis, and inflammatory gene expression, while several main circulating oxidative-stress measures did not differ from plain water. Clinical findings remain modest and depend on the population and outcome.”
