Supplements for GLP-1 side effects

Products sold for the nausea, constipation and hydration problems that come with GLP-1 medications, and an honest account of what they can address.

Constipation, nausea, fatigue and low fluid intake are the ordinary companions of these medications, and some of them respond to fibre, electrolytes or magnesium. Two things worth being clear about: bloating and fullness on a GLP-1 come from deliberately slowed gastric emptying rather than poor digestion, so enzymes are not addressing that mechanism — and persistent vomiting or severe abdominal pain is a call to your prescriber, not a shopping trip.
