LMNT electrolyte product contains sodium, potassium, and magnesium malate, which may offset delayed onset muscle soreness and does not cause drowsiness or anxiety.

“LMNT. L-M-N-T. LMNT. I learned about this from Lex Friedman's podcasts. I know many of you are familiar with Lex, has a excellent podcast, excellent scientist. I don't have any business relationship to LMNT. They're not a sponsor of the podcast, but LMNT is a product that essentially contains electrolytes: sodium, potassium, as well as magnesium malate, which has been shown to offset things like delayed onset muscle soreness. That form of magnesium doesn't make people drowsy. It's not an anxiolytic like some other forms of magnesium.”
