Has anyone tried this ?

Myers Cocktail 101

The Myers cocktail contains a variety of nutrients:
5 milliliters (mL) magnesium chloride hexahydrate
3 mL calcium gluconate
1 mL hydroxocobalamin
1 mL pyridoxine hydrochloride
1 mL dexpanthenol
1 mL B-complex (thiamine, riboflavin, niacinamide) vitamins
5 mL vitamin C

Just curious

Also curious if insurance would cover something like this?
