Lactation

 

14 through 50 y

Intake level to lower blood pressure, reduce the extent of salt sensitivity, and to minimize the risk of kidney stones in nonlactating adults plus the average amount of potassium estimated in breast milk during the first 6 months (0.4 g/d)

 

5.1

aNo Tolerable Upper Intake Level is established; however, caution is warranted given concerns about adverse effects when consuming excess amounts of potassium from potassium supplements while on drug therapy or in the presence of undiagnosed chronic disease.

bAI = Adequate Intake. The observed average or experimentally determined intake by a defined population or subgroup that appears to sustain a defined nutritional status, such as growth rate, normal circulating nutrient values, or other functional indicators of health. The AI is used if sufficient scientific evidence is not available to derive an Estimated Average Requirement. The AI is not equivalent to a Recommended Dietary Allowance.
