Nutrients people taking GLP-1 medications (such as semaglutide or tirzepatide) most often ask about — reduced appetite can lower protein and micronutrient intake, so protein, magnesium, electrolytes, fibre and key vitamins come up frequently. This is a cost-per-dose value comparison, NOT medical advice: talk to your prescriber, and never change or stop a medication because of a supplement. Best value right now: Creatine Monohydrate from <$0.001/g.

Ranked by real cost per dose (per gram for powders), not sticker price. We make no health claims — see each linked nutrient page for NIH-sourced facts, or read our methodology.
This page gathers the nutrients people commonly associate with glp-1 companion and ranks each one by cost per dose— the product’s current price divided by its servings per container, then normalized to one daily dose (or per gram for powders so a 20 g and a 25 g serving compare fairly). The table shows the single cheapest pick we currently track for each nutrient, sorted lowest cost first. Nothing here is paid placement, and a nutrient with no active deals simply drops off the list.
If you are assembling a stack for glp-1 companion, cost per dose is the figure that tells you what each option actually costs to take day after day — a smaller bottle with a lower sticker price can cost more per serving than a larger one. Use it to compare like-for-like and avoid overpaying; it is a price-comparison signal, not a measure of quality or suitability.
