IntroductionDietary supplements are touted for cognitive protection, but supporting evidence is mixed. COSMOS-Mind tested whether daily administration of cocoa extract (containing 500 mg/day flavanols) versus placebo and a commercial multivitamin-mineral (MVM) versus placebo improved cognition in older women and men.MethodsCOSMOS-Mind, a large randomized two-by-two factorial 3-year trial, assessed cognition by telephone at baseline and annually.

Vitamin D deficiency and C-reactive protein: a bidirectional Mendelian randomization study
AbstractBackgroundLow vitamin D status is often associated with systemic low-grade inflammation as reflected by elevated C-reactive protein (CRP) levels. We investigated the causality and direction of the association between vitamin D status and CRP using linear and non-linear Mendelian randomization (MR) analyses.MethodsMR analyses were conducted using data from 294 970 unrelated participants of White-British ancestry from …
Rapidly Increasing Serum 25(OH)D Boosts the Immune System, against Infections—Sepsis and COVID-19

The same groups were worst affected by COVID-19. Since vitamin D deficiency weakens …
High-dose Vitamin B6 supplementation reduces anxiety and strengthens visual surround suppression
ObjectiveVitamins B6 and B12 are involved in metabolic processes that decrease neural excitation and increase inhibition. This double-blind study investigated the effects of supplementation for 1 month with a high-dose of B6 or B12, compared to placebo, on a range of behavioural outcome measures connected to the balance between neural inhibition and excitation.Methods478 young adults …
