NIH adds: “Extremely high levels of vitamin D can cause kidney failure, irregular heartbeat, and even death.”
Nonetheless, in April 2020, the NHS issued a statement, based on recommendations from Public Health England (PHE), that we should all consider taking 10 mcg/day vitamin D as a supplement, to keep our bones and muscles healthy.
This advice was issued largely because of the restrictions imposed by quarantine and lockdown.
Despite this, the NHS says that in summer months, the majority of the population will get enough vitamin D through exposure to sunlight and a healthy, balanced diet.
