Supplements and GLP-1 agonists.
GLP-1 agonists (semaglutide, liraglutide, tirzepatide) slow gastric emptying and reduce appetite. The interaction surface is not classical pharmacology so much as logistics: at substantially lower food intake, micronutrient adequacy stops being automatic.
The supplement questions worth asking on a GLP-1 are mostly about coverage: protein adequacy first (whey or pea protein at 25 to 40 g per day is a reasonable floor for muscle preservation), then a multivitamin for general micronutrient cover, then magnesium if cramps or sleep change. Slower gastric emptying may push timing of mineral supplements toward later in the day. We are still expanding direct GLP-1 interaction coverage; tell us what you take and we will check.
