Potassium

How does Potassium work?

Potassium plays a role in many body functions including transmission of nerve signals, muscle contractions, fluid balance, and various chemical reactions.

Are there safety concerns?

Potassium is safe for most people when taken by mouth in amounts of up to 90 mEq of total potassium from the diet and supplements combined. For pregnant or breast-feeding women, safe amounts are obtained from the diet in amounts of 40-80 mEq per day. Potassium can cause stomach upset, nausea, diarrhea, vomiting, intestinal gas, and other side effects.

Too much potassium is dangerous and can cause feelings of burning or tingling, generalized weakness, paralysis, listlessness, dizziness, mental confusion, low blood pressure, irregular heart rhythm, and death.

Do not take potassium if:
  • You have disorders of the digestive tract that might alter the speed food and supplements pass through the body.
  • You are sensitive to aspirin or tartrazine products.
