Contrary to many threads on this forum about Vit D, recommended levels for general health, and specific benefits for a whole range of diseases, a new long review of the evidence.

How Much Vitamin D Do You Need to Stay Healthy?
Most people naturally have good vitamin D levels. Overhyped claims that the compound helps to fight diseases from cancer to depression aren’t borne out by recent research

I personally have been given this new advice by an osteoporosis specialist. High levels of Vit D, my goal range 50-99, has been correlated with increased fracture risk. Details of these new studies and more in the latest issue of Scientific American.

Other experts still advise higher levels. Vitamin D fans will not be happy, Dr Holick is called out for his books and hype.
Make of it what you will!
