Do other people here that use topical or oral Magnesium, and Potassium supplements also use Calcium? I know that intra cellular Magnesium and potassium does not show up in blood tests but do not know the case for calcium. As for myself I use a potassium powder and topical magnesium but get my calcium through diet; mainly forms of goat dairy. I don't know if loading up on potassium and magnesium would deplete calcium but its in normal range for my blood tests. I am also experiencing super gnarly tendonitis all over my damn body from bumping up antibiotics, never been this bad before and never had a single twinge or pain in my entire body for my life until getting sick. Wondering if this will help with that or if there is any suggestions on what to do for it. I do not use nor have I ever used quinoline antibiotics so I know its not from a drug side effect.
