The GLP-1 Companion Guide: Protecting Muscle, Protein & Digestion

Educational content, not medical advice. We make supplements, not medications — nothing here replaces your prescriber's plan, and we are not affiliated with any GLP-1 medication.

GLP-1 medications changed what weight loss looks like for millions of people. What they didn't change: your muscle still needs protein and a reason to stay, and your digestive system — now deliberately running slower — still needs fiber, fluid, and support. Those jobs used to be handled incidentally by the sheer amount of food you ate. Now they need to be handled on purpose.

This guide is the map. Each section links to a full article, and every product mentioned prints its complete dose on the panel — because if you're managing your health this deliberately, you deserve a label that tells the truth.

Job one: hit your protein number anyway

Appetite suppression pulls protein intake down right when your body needs it most. Target roughly 0.6–0.7 g per pound of goal weight, put protein first at every meal, and lean on liquid protein when solid food won't cooperate — a whey isolate gives you ~25 g in a glass with minimal lactose and volume.

Job two: give your muscle a reason to stay

Fast weight loss without countermeasures takes lean mass with it. The three proven countermeasures: resistance training 2–4× a week, the protein target above, and 3–5 g of creatine daily — creatine supports the strength and training volume that keep muscle from becoming optional. Pure Power is Creapure®, the 99.9%-pure reference standard.

Job three: support a digestive system running slower on purpose

Slowed gastric emptying is the mechanism, and constipation, bloating, and quiet dehydration are its side effects. Soluble fiber (Myofiber, 5 g per serving, ramped up gradually), digestive enzymes with protein meals (built into Nitro^UP), and electrolytes to make water worth drinking (Super8) each map to one of those problems.

The GLP-1 companion stack

• ISO^UP — the protein gap, closed in one glass a day (or two on the hard days)
• Pure Power — 5 g Creapure® daily for strength and muscle retention
• Myofiber — 5 g soluble fiber for the regularity problem everyone gets and nobody mentions
• Super8 — electrolytes + aminos so hydration actually happens

Not sure you need all four? Take the 60-second Stack Finder, or read the Ingredients Guide and decide ingredient by ingredient — it's written to be useful even if you never buy from us.

The honest part

No supplement makes a GLP-1 work better, and anyone telling you otherwise is selling you something. What supplements can do is cover the jobs the medication leaves behind — protein, muscle, digestion — with doses you can verify on the panel. That's the standard this company was built on in 2003, and it's the same one we hold on every label today.
