Lose the fat. Keep the muscle.

On a weight-loss medication — GLP-1s like Ozempic or Wegovy, the next wave of drugs, or dieting on your own — the scale can drop fast, but up to 40% of what you lose can be muscle, and your nutrition falls with your appetite. Proco gives you the evidence-dosed essentials to protect your muscle, heart and metabolism while you lose, so you come out stronger, not just smaller. Every ingredient is backed by human clinical trials. If the evidence is not there, we do not stock it.

What we focus on — and why.

Protect your heart

Omega-3, berberine and magnesium — each shown in human trials to support healthy cholesterol, blood sugar and blood pressure while you lose weight.

Protect your muscle

Rapid weight loss strips lean muscle. Protein and creatine, backed by human trials, help you hold onto the muscle that keeps you strong and your metabolism healthy while you lose.

We start with supplements — and build the support around you.

Losing weight well is about more than what is in the bottle. Alongside the stack you get plain, cited guidance on protecting your muscle, heart and metabolism, the right routine for where you are, and a brand built to support you through the whole journey — not just sell you a tub. Proco is an evidence-first obesity & cardiometabolic health company: supplements are where we start.

On a GLP-1 or weight-loss medication? Come out of it stronger.

GLP-1s and the new generation of weight-loss medications are a powerful tool, and the right supplements help you get the very best from them. Research shows up to 40% of weight lost on these medications can be muscle — so Proco's GLP-1 Support Stack is built to protect it. Four evidence-backed essentials in one: protein and creatine to defend and rebuild lean muscle, omega-3 for heart health, and magnesium to cover the nutrient gaps that come with eating less — all among the most researched compounds in human science. All backed by human trials.

Frequently asked

Do I need supplements while on a weight-loss medication?

On a GLP-1 or other weight-loss medication you eat far less, so protein and key nutrients fall short and rapid weight loss draws from lean muscle as well as fat. The stack helps you protect muscle, heart and metabolic health while you lose.

What's in the GLP-1 Support Stack?

Whey protein, creatine, omega-3 (EPA+DHA) and magnesium — four evidence-backed essentials, €99 (save €22 vs buying separately).

How do I take it?

A simple daily routine — a protein serving and creatine daily, omega-3 with a meal, and magnesium in the evening.

Are Proco supplements safe?

Every product is dosed to published human-trial ranges, made in GMP/HACCP-certified facilities and batch-tested with a Certificate of Analysis. If you take medication or are pregnant, check with your clinician.
