The Top 3 Supplements to Consider While Taking GLP-1s

GLP-1 medications can change the way you eat. Appetite drops. Portions get smaller. Some days, even finishing a normal meal can feel like a job.

That can be useful for weight management, but it also means your nutrition has to work harder. When you are eating less, every scoop, snack and meal needs to earn its place.

Supplements are not a replacement for food, and they are not medical treatment. But the right basics can help you stay consistent with the things that matter most: protein, fibre and fluids.

Always follow your prescriber’s advice, especially if you have diabetes, kidney disease, digestive issues, or you are taking other medication.

1. Protein Powder

Protein should be the first priority.

When appetite is low, it can be harder to get enough protein from meals alone. That matters because protein contributes to the growth and maintenance of muscle mass. During weight loss, especially rapid weight loss, supporting muscle through protein intake and strength training is a smart move.

A shake can help because it is simple, portion-controlled and easier to manage than a full meal when you do not feel very hungry.

Good options include:

2. Fibre

GLP-1 medications can slow digestion, and many people naturally eat less fibre because they are eating less overall.

Fibre should still start with food: vegetables, fruit, oats, beans, lentils, wholegrains, chia seeds and flax seeds. But if your intake has dropped, a fibre supplement can be useful when introduced gradually.

Go slowly. Suddenly adding lots of fibre can make bloating or digestive discomfort worse, especially if you are not drinking enough.

A sensible approach:

3. Electrolytes

When food intake drops, fluid intake often drops too. Add training, hot weather, nausea, vomiting or diarrhoea, and hydration can become harder to stay on top of.

An electrolyte drink can make fluids easier to drink consistently, especially around training sessions or on days where plain water is not appealing.

Look for a low-sugar option and check the label. If a product contains qualifying levels of minerals such as magnesium or potassium, those nutrients may carry authorised claims such as contributing to electrolyte balance or normal muscle function.

What About Creatine?

If you already have protein, fibre and hydration covered, creatine is worth considering if you train regularly.

Creatine increases physical performance in successive bursts of short-term, high-intensity exercise, with the beneficial effect obtained from 3g per day. For HYROX, CrossFit and hybrid training, that makes it a strong performance staple.

But while taking GLP-1s, cover the basics first: protein, fibre and fluids.

The Simple GLP-1 Supplement Stack

Then add creatine if you are training hard and want a performance-focused fourth.

Small appetite does not have to mean poor nutrition. Keep the stack simple, keep meals nutrient-dense, and build around what your body can tolerate consistently.
