Whey Protein Isolate
Protects lean mass when protein intake drops on a reduced-calorie diet.
GLP-1 Companion Nutrition
The protein, creatine, magnesium, and gut support your body still requires. Formulated specifically for people on GLP-1 medications.
Chapter I
GLP-1 medications reduce appetite. That is what they are designed to do. But your muscles do not know that. Your cells do not know that. The parts of your body that depend on consistent protein, creatine, magnesium, and fiber intake do not adjust when your plate gets smaller.
The gap between what you are eating now and what your body still requires is real. It is not a motivation problem. It is a math problem.
Anchor is built to fill that gap.
Understand the physiology
Chapter II
GLP-1 medications are effective. The side effects are documented. Here is what the clinical evidence says about what your body still needs.
In the SURMOUNT-1 trial (tirzepatide, NEJM 2022), a portion of weight lost was lean mass, not only fat. Adequate protein and creatine protect what your body is working to keep.
Your cells use phosphocreatine to regenerate ATP, the molecule that powers everything from walking to thinking. When food intake drops, creatine stores follow. This is not a stimulant problem. It is a substrate problem.
Magnesium depletion is common on GLP-1 therapy. Constipation is a top-five reported side effect in both STEP 1 and SURMOUNT-1. Magnesium glycinate is the form with the highest gut tolerability. It also supports sleep quality, separately relevant during dose escalation.
GLP-1 medications slow gastric emptying intentionally. Slower digestion means less fiber absorbed, more constipation risk, and incomplete nutrient breakdown. Prebiotic fiber and digestive enzymes support what the medication is changing.
Chapter III
Each Anchor product addresses a specific physiological gap documented in GLP-1 trial data. Not a general wellness line. Targeted.
Protects lean mass when protein intake drops on a reduced-calorie diet.
Supports cellular energy and muscle protein synthesis on a GLP-1 protocol.
Relieves GLP-1-related constipation. Supports sleep during dose escalation.
Chapter IV
The data on GLP-1 medications and nutritional needs is not ambiguous. These numbers come from published clinical trials. Anchor products address what the science documents.

Chapter V
The questions people on GLP-1 medications actually ask. Direct answers, with sources.
Not categorically. But GLP-1 medications reduce the volume of food you eat, and with that comes reduced protein, magnesium, fiber, and creatine intake. Whether those gaps cause problems depends on what you were eating before, your body composition, and how your medication affects you. The SURMOUNT-1 trial documented lean mass loss as a secondary outcome. The STEP 1 trial listed constipation in the top adverse events. These are not rare edge cases. Anchor products address what the data documents.
GLP-1 medications slow gastric emptying. This can affect the absorption timing of other substances. None of the Anchor products are contraindicated with semaglutide or tirzepatide based on current prescribing information. That said, your prescribing physician knows your complete medication list. Tell them what you are taking. That is not a liability disclaimer; it is practical advice.
Yes. The evidence base on creatine monohydrate is one of the most robust in sports nutrition science. Lanhers et al. (Journal of Sports Medicine, 2017) confirmed creatine's role in muscle strength and ATP regeneration. Female-specific trials show equivalent benefit with no adverse hormonal effects. The myth that creatine is a men's supplement traces to its marketing history, not its biology.
Morning: Whey Protein Isolate, Creatine Monohydrate, Complete Multivitamin, Omega-3 EPA+DHA. With your largest meal: GLP-1 Support Complex, Digestive Enzyme Pro Blend. Between meals: Creatine + Electrolyte Hydration for hydration and cramp prevention. Evening (30 minutes before bed): Magnesium Glycinate, Gut Health Prebiotic Fiber. These are practical defaults based on absorption research and GLP-1 side effect timing. Adjust for your routine.
A general multivitamin does not address the specific gaps GLP-1 users face. It does not include creatine. It does not include therapeutic-dose magnesium glycinate for constipation. It does not include prebiotic fiber. It was not formulated with the documented side-effect profile of GLP-1 medications in mind. Anchor products are specific. Each one addresses a documented need, not a general one.
