Three dimensions are assessed separately for each nutrient. The evidence basis column distinguishes direct GLP-1 trial data from bariatric extrapolation and mechanistic reasoning. Deficiency risk and supplementation evidence are rated independently. Tap any row to expand clinical detail.

Bariatric extrapolation entries draw on post-bariatric surgery cohorts. This literature establishes direction of risk but likely overestimates absolute deficiency magnitude in GLP-1 users whose gastrointestinal anatomy is intact. All ratings reflect the best available evidence and state their basis explicitly where direct GLP-1 data are absent.
