“According to animal research, even mild vitamin C deficiency may impact fetal hippocampal development, a part of the brain crucial for learning and memory. From the article: > "Even marginal vitamin C deficiency in the mother stunts the fetal hippocampus, the important memory centre, by 10-15 per cent, preventing the brain from optimal development," says Professor Jens Lykkesfeldt.”

“They were also dementia-free longer than those without vitamin D exposure. These effects were evident across various forms of vitamin D. Further analysis revealed that sex, cognitive status, and APOE4 status influenced the extent of vitamin D's effects on dementia risk.”

“Low levels of plasma omega-3 polyunsaturated fatty acids were associated with more severe cerebral small vessel diseases in patients who had experienced an ischemic stroke. Participants with the highest serum concentration of vitamin D had fewer white matter hyperintensities, enlarged perivascular spaces, and total burden of small vessel disease.”

“The study involved more than 12,000 cognitively healthy older adults. Researchers gathered information about the participants' vitamin D supplementation practices and whether they developed Alzheimer's over 10 years.”

“A supplement containing the active form of vitamin D was shown to prevent autistic-like behaviors in mice that are predisposed to them. The active vitamin D was given to pregnant mice during the first trimester and this prevented deficits in social interaction, basic learning, and stereotyped behaviors.”

Dr. Rhonda Patrick discusses iron imbalances, urolithin A, NAD+ boosters, vitamin K2 and hormone replacement therapy in women.

“Multiple sclerosis has also been linked to genetically low vitamin D...meaning a gene that converts vitamin D into active vitamin D hormone does not work well in many MS patients so they need an unusually high dose of vitamin D.”

“Most studies seem to show a reduction in all-cause mortality (or improvements of various outcomes) when blood status is above 40ng/ml but not in excess of 60ng/ml. I've referred to this as the Vitamin D sweet spot before and I think it makes a good argument for blood testing occasionally.”

“Each 10nmol/L increase in vitamin D in the blood was associated with a 0.78 mL/kg/min increase in VO2 max. This was an observational study so it is impossible to say whether vitamin D improves exercise capacity but the association was strong and increased in a dose-dependent manner.”

“Most people living in the United States obtain sufficient protein, carbohydrates, and fats in their diet. However, many people lack essential vitamins and minerals, which must be obtained from our diets since we cannot make them.”
