Dietary potassium deficiency in the elderly: a controlled trial
Age and Ageing
|August 1, 1975
Summary
This study found that potassium supplements did not improve grip strength or mental function in elderly individuals with low dietary potassium. The potential risks of widespread supplementation outweigh any unproven benefits.
Area of Science:
- Gerontology
- Nutritional Science
- Clinical Trials
Background:
- Elderly individuals often have suboptimal dietary potassium intake.
- Low potassium levels can potentially affect physiological functions.
Purpose of the Study:
- To investigate the effects of potassium supplementation on grip strength and cognitive function in the elderly.
- To assess the efficacy of 48 mEq daily potassium supplementation.
Main Methods:
- A controlled cross-over trial involving 46 elderly participants.
- Participants had a dietary potassium intake of ≤45 mEq/day.
- Intervention involved two weeks of potassium supplementation versus placebo.
Main Results:
- No significant improvements in grip strength were observed with potassium supplementation.
- No significant improvements in mental function were noted compared to placebo.
- The study did not demonstrate benefits from the tested potassium dose.
Conclusions:
- Widespread potassium supplementation in the elderly may not offer significant benefits.
- The potential risks associated with potassium supplementation should be carefully considered.
- Current evidence does not support routine potassium supplementation for this population.
