“Vitamin D is Dr. Patrick's second priority because sun-derived production varies with age, skin pigmentation, latitude, clothing, and sunscreen use. Her third choice, sulforaphane, is formed from glucoraphanin in cruciferous vegetables and activates NRF2-regulated cellular defense pathways.”

“The finding adds to evidence that adequate micronutrient intake may support cognitive resilience with age. Dr. Patrick also discusses vitamin D, omega-3s, ubiquinol, and sulforaphane in the context of her father's Parkinson's disease, medication use, and her mother's experience.”

“In this clip, Bruce Ames says that although he eats a very healthy diet, he still takes a vitamin D supplement. Individual requirements for nutrients can vary significantly. In addition it can be hard to keep track of the nutrient content of the food one eats.”

“Vitamin D production in skin declines with age, while omega-3 dose needs vary with baseline status, body weight, chemical form, and EPA plus DHA intake. These differences favor laboratory-guided and diet-aware decisions over one universal dose for every older adult.”

“A national survey analysis estimated severe vitamin D deficiency in 2.6% of US adults, moderate deficiency in 22%, and insufficiency in 40.9%, with prevalence changing according to the threshold used. Testing can help match intake to an individual's starting status.”

“She starts with vitamin D testing and marine omega-3 intake, then uses a high-quality multivitamin and magnesium to cover nutrients that can be difficult to obtain consistently from a typical diet. Omega-3 dosing depends on the actual EPA and DHA content shown on the label.”

“Adults with alcohol use disorder have a 20%–50% greater prevalence of calcium deficiency, a 25%–50% greater prevalence of magnesium deficiency, a 6%–80% greater prevalence of deficiencies in many B vitamins, and a 14%–58% greater prevalence of deficiencies in vitamins C, D, E, and K.”

“Participants with vitamin D deficiency (less than 12 nanograms per milliliter) were 1.62 times more likely to have opioid use disorder. In mice, vitamin D deficiency increased the rewarding and pain-relieving effects of UV exposure through altered gene expression in key brain regions.”

“Vitamin D plays critical roles in many physiological processes, such as calcium balance, blood pressure regulation, immune function, and cell growth. Poor vitamin D status is implicated in the pathogenesis of many acute and chronic diseases, including rickets, osteoporosis, multiple sclerosis, and cancer.”

“Having high vitamin D levels may protect the brain, however. Researchers measured vitamin D levels and reviewed MRI brain studies of more than 1,800 adults to identify associations between vitamin D levels and total brain, gray matter, and hippocampal volumes.”
