Micronutrients & recovery
Sodium (Na+) and Potassium (K+) levels in iontophoretic sweat are positively correlated within individuals, but across a population, individuals with higher sodium levels tend to have lower potassium levels.
If you are monitoring electrolytes, be aware that your body's balance of sodium and potassium in sweat is individual. High sodium excretion might correlate with lower potassium excretion for you specifically, but this pattern may not hold true when comparing you to others.
ModerateQualifiesMEDIUM confidence
Comparing these ranges across individuals in Fig. 4 (I and J), subjects with relatively higher [Na+] tend to have lower [K+].
Why this rating
Small sample size (n=3 subjects for detailed analysis, n=several for population range).
