Review of the potential benefits of vitamin D for COVID-19 in relation to neuroprotection. Authors note that neurological symptoms are common in COVID-19, likely related to disruption of the blood-brain barrier, inflammation, and immunothrombosis (clotting). Vitamin D could help protect the integrity of the blood-brain barrier and reduce neuroinflammation. In vitro and animal studies show vitamin D reduces inflammatory cytokine production, shifts microglia to an anti-inflammatory phenotype, promotes myelination, and has antioxidant effects in the brain, which suggests a neuroprotective role. Note that lumisterol and tachysterol are created via sun exposure. Vitamin D supplementation can provide the active calcitriol metabolite with direct anti-inflammatory and immunomodulatory effects, however supplementation alone will not provide the active hydroxylated metabolites of lumisterol and tachysterol that come from sun exposure. Sun exposure may provide additional immune benefits.
