Magnesium deficiency- when do I know my levels are back up ?

[Bornin1969]

I have started taking magnesium flakes bath and when not doing that i’m Spraying magnesium oil on myself. When will I know my levels are back up? I’m doing this because I have horrendous pms and I was told maybe I had a magnesium deficiency so I’m doing that ! Also anything else i could take to help with this ? Thank you

you should take magnesium citrate, it's the quickest absorbed and more effective than via skin

take it for 3 months then ask for levels to be tested?
