What is a safe, sugar-free potassium supplement (that does not include sodium!) i can buy to boost my electrolytes? other than food.

Yes: Take k-dur 20 meq twice a week for 3 months.

Why?: For what purpose are you doing this? If you are potassium deficient there must be some reason, and approaching the cause rather than the supplementation would be a better approach. Very few individuals need potassium supplements. Consult with you local pcp.

Safe potassium: Brand name "No Salt" is potassium chloride. No sodium. Health food stores have potassium tabs without sodium..
