My calcium levels were then found to be depleted so I was put on Calcium/D3 tablets (daily dose 3000mg calcium/800 units D3), but my smell didn't return. After discussion with my doctor he agreed to supplement the Calcium/D3 tabs with an extra daily dose 1,600 units of D3. Three weeks later glorious smell returned.
Sense of smell is governed by the olfactory nerves in the nose which send messages to the brain. Vitamin D3 is important for the neurological pathways in the body. Quid pro quo. I hope my journey helps someone else.
