Best Companion Supplements for GLP-1 Users
If you're already taking Wegovy, Zepbound, Ozempic or Mounjaro, this is the category that matters. These products don't claim to boost anything — they cover the protein and micronutrient gaps that eating substantially less creates, which is the problem that determines how much of your weight loss is fat rather than muscle.
Why this category has better evidence than boosters
Companion supplementation doesn't depend on any claim about hormone modulation. It rests on arithmetic: if a medication cuts how much you eat, your protein and micronutrient intake falls with it. That's not a hypothesis, it's a consequence.
The consequence that matters most is lean mass. Roughly a quarter to a third of weight lost on GLP-1 therapy is lean tissue rather than fat, and that ratio responds reliably to only two things — adequate protein intake and resistance training. Everything on this page targets the first.
What to prioritise, in order
- 1. Protein. Aim for roughly 1.2 to 1.6 g per kg of body weight while losing weight. Protein-dense whole foods are the least appealing thing on a suppressed appetite, which is why a shake usually beats advice to eat more chicken.
- 2. Fibre. Constipation is one of the most common GLP-1 side effects, and reduced food volume means reduced fibre. Introduce it gradually — GLP-1s already slow gastric emptying.
- 3. Micronutrients. Iron, B12, vitamin D and calcium intake all fall with total food volume. A multivitamin covers most of this cheaply.
- 4. Hydration and electrolytes. Easy to overlook when you're not eating much and not thinking about food.

A gut-support option worth knowing about
Many GLP-1 patients find their worst problem isn't nutrition but the GI side effects — bloating, constipation and general digestive discomfort caused by slowed gastric motility. Our top-rated product overall, CoreAge Rx GLP-1 Support, is technically a booster but is frequently taken alongside a prescription for exactly this reason. Worth a look if digestion rather than protein is your sticking point.
