Carnivore Foods to Cover Electrolyte Needs:
Sodium:
Salt (unrefined sea salt, Himalayan pink salt, or Redmond Real Salt)
Bone broth (rich in sodium when simmered from bones)
Potassium:
Beef (especially muscle cuts)
Pork (particularly in lean cuts)
Chicken (dark meat like thighs and drumsticks)
Bone broth (contains potassium from bones)
Magnesium:
Organ meats (especially liver)
Bone broth (rich in magnesium if simmered long)
Calcium:
Canned fish with bones (e.g., sardines, salmon)
Bone broth (contains calcium from the bones)
Dairy (if tolerated, such as cheese or heavy cream)
Chloride:
Salt (as chloride is bound to sodium)
Bone broth (contains chloride along with sodium and potassium)
If you don't think you can cover your electrolytes with natural foods, I recommend Redmond's Relyte in the unflavored version. It's the best price-to-quality mix I've found. https://redmond.life/products/re-lyte-hydration?variant=39646809686064
E-Lyte is great too:
