Vitamin D
An April 2021 study by Garvan Institute of Medical Research, Australia, said
"Our results show there is a clear link between vitamin D deficiency and oxidative capacity in skeletal muscle. They suggest that vitamin D deficiency decreases mitochondrial function, as opposed to reducing the number of mitochondria in skeletal muscle."
"We are particularly interested to examine whether this reduction in mitochondrial function may be a cause of age related loss in skeletal muscle mass and function."
A March 2021 study lead by the University of Birmingham and University of Manchester said,
"Our results suggest that co-existing physiological abnormalities may contribute to long-term cardiovascular risk early on in [lupus].”
"We found a link between lower levels of vitamin D and metabolic syndrome and insulin resistance. Further studies could confirm whether restoring vitamin D levels helps to reduce these cardiovascular risk factors and improve quality of life for patients with lupus."
"This is the largest-ever study examining associations between vitamin D levels and metabolic syndrome in [lupus]; it also has the advantage of being an international cohort with diverse racial and ethnic backgrounds - generating results that will be applicable across many settings,"
A December 2020 study by the University of Queensland finds that there may be a link between vitamin D deficiency during pregnancy and autism spectrum disorder in boys.
The researchers found “…vitamin D deficiency during pregnancy caused an increase in testosterone in the developing brain of male rats … The biological cause of Autism spectrum disorder (ASD) is unknown but we have shown that one of the many risk factors--low vitamin D in mothers--causes an increase in testosterone in the brain of the male foetuses, as well as the maternal blood and amniotic fluid…In addition to its role in calcium absorption, vitamin D is crucial to many developmental processes…Our research also showed that in vitamin D-deficient male foetuses, an enzyme which breaks down testosterone was silenced and could be contributing to the presence of high testosterone levels.”
