“Researchers fed mice diets containing low, moderate, or high doses of vitamin D for four weeks to induce deficient, normal, and high vitamin D concentrations, respectively. Then, they measured changes in the animals' blood concentrations of leptin and myostatin and assessed their strength.”

“Many medications accelerate vitamin D inactivation, including commonly prescribed blood pressure medications such as nifedipine and spironolactone. Learn more about vitamin D in our comprehensive overview article.”

“Dopamine is a neurotransmitter best known for its role in motor, motivation, and pleasure control. A new study highlights vitamin D's influence on dopamine signaling and emphasizes its essential role in the normal development of dopamine-producing cells.”

“They found that vitamin D inhibited hyperglycemia-induced NLRP3 activation and IL-1 beta production, leading to lower levels of inflammation. Further investigation revealed that vitamin D upregulated AMPK production in the cells, which likely contributed to the reduction of inflammation.”

“Evidence suggests that people with vitamin D deficiency are at greater risk of viral infection and autoimmune disorders. This is in keeping with the widely held belief that a principal role of vitamin D is to restrain, or balance, immune system activity.”

“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.”

“The duration of supplementation ranged from three weeks to five years with a maximum dose of 150 milligrams of elemental zinc per day. Sixteen studies supplemented with zinc alone and nine studies supplemented with zinc along with other vitamins and minerals.”

“A recent study found that higher vitamin D levels may reduce the risk of developing dementia in older adults with prediabetes. Researchers drew on data collected from a large cohort of more than 34,000 older adults enrolled in the UK Biobank, all of whom had prediabetes but did not have dementia at the start of the study.”

“All of these enzymes are magnesium dependent, and evidence suggests that magnesium deficiency impairs vitamin D metabolism. Vitamin D influences serotonin synthesis via its actions on tryptophan hydroxylase 2, a rate-limiting enzyme involved in serotonin production.”

“The podcast presenters describe vitamin D synthesis, its role in immune regulation – including how it prevents cytokine storms – and why it might be the key to fending off COVID-19. Link to the episode.”
