I have been taking 600 mg 2x daily of calcium for years.

Multi vitamin with emphasis on B12
2000 IU D3 (for past ten years as blood tests showed I was at a 16! back in the day!
Plant based diet, no grains, no alcohol, no dairy…(this is a recent switch for me)
Have increased my exercise to 5 c a week (20-30 min) I do a Nike workout that is on Netflix (lots to choose from, no equipment necessary)

I’m also on hormone therapy (recently finally in menopause) that predates the covid pandemic.

Hmmm, what else…
Started Wellbutrin and very low dose of generic adderall to help with the memory and depressive symptoms that arose like a switch flipped immediately following my covid infection in 10/2022
