Best Gentle, Low-Dose Electrolytes
Not everyone needs a salty bolus. People eating less than usual — including many people on GLP-1 medication, who often look for small, easy sips rather than a big sweet glass — and anyone whose stomach rebels at strong drinks usually do better starting here: low-to-moderate doses, small servings, nothing harsh. Sip slowly, and if nausea or dizziness persists, that is a conversation for your clinician, not a shopping page.
