Creatine

Cheap, proven, and muscle-protective.

What it is

Creatine is one of the most-studied supplements there is — a compound your muscles use for quick energy. Plain creatine monohydrate is the gold standard: inexpensive, well-tolerated, and effective.

Why the experts include it

Creatine has moved from a 'gym' supplement to a mainstream pick among longevity-minded experts, valued for supporting strength, muscle, and increasingly cognition. The near-universal advice is to keep it simple — pure monohydrate, with Creapure a common gold-standard raw material.

Why it matters on a GLP-1 journey

When you're eating less, holding onto muscle becomes the priority — and creatine, paired with protein and a little resistance training, is one of the most reliable tools for that. It adds almost no volume, which helps when appetite is low.

Creatine to hold onto muscle

Alongside protein and a little resistance movement, creatine monohydrate is one of the most reliable, well-studied ways to help hold onto muscle while you're eating less — and it adds almost no volume.

General amounts (not a prescription)

A common daily amount is around 3–5 g of creatine monohydrate — follow the label.

Common questions

Is creatine worth taking on a GLP-1?

Creatine monohydrate is one of the most studied supplements in nutrition, with a strong safety record in healthy adults. It's especially relevant when you're losing weight and want to hold onto muscle. If you have kidney concerns, mention it to your clinician before starting — standard advice for anyone, not specific to a GLP-1. Otherwise, around 3–5 g a day of monohydrate is the usual amount.

How much creatine should I take to help protect muscle?

About 3 g of creatine monohydrate a day saturates your muscle stores over a few weeks without any loading phase. Loading (a higher amount for a week) works faster but can bring temporary water weight and some stomach discomfort — less ideal when digestion is already adjusting. A steady 3–5 g daily in water or a shake is simpler and just as effective over time.

Creatine or protein — which matters more for muscle?

Protein comes first. Hitting your daily protein target is the main driver of holding onto muscle. Creatine supports the strength and power you put into a little resistance training, which helps you make use of that protein. Protein is the building material; creatine is a helpful tool. Cutting protein to make room for creatine is the wrong trade.

Does creatine cause bloating?

Creatine pulls a little water into your muscle cells, which can nudge the scale up by a pound or two of water — that's inside the muscle, not the puffy kind from sodium or digestion. Stomach discomfort is uncommon at 3–5 g a day and more likely during a loading phase. If your stomach is already sensitive, skip loading and start at 3 g a day with plenty of water.

When's the best time to take creatine?

Consistency matters more than timing. Many people take it after a workout with a shake because it's easy to remember and pairs with protein. On rest days, any time with a little food works. On a smaller appetite, mixing it into a drink rather than adding it to an already-small meal keeps the volume down. Pick a daily anchor and stick with it.
