My bloods have shown I am deficient in Vitamin D. I already have a 1000iu (25mcg) spray but my endocrinologist has recommended I get a 3000iu (75mcg) spray.
The NHS website advises not to exceed 25mcg vitamin D in supplementation
If you take vitamin D supplements, do not take more than 25 micrograms (0.025mg) a day, as it could be harmful.
Does anyone know which advice I should follow, which is correct?
