Managing GLP-1 Side Effects with Nutrition: Fibre, Hydration & Electrolytes (Canada 2026)
Constipation, dehydration, low energy and occasional nausea are common on GLP-1 medications like Ozempic and Wegovy. No supplement treats these, but a few nutrition basics — fibre, hydration, electrolytes and key vitamins — can make your day more comfortable while your provider handles the medical side. Here’s a practical, non-medical playbook with the in-stock products we recommend.

Side effects are common — and nutrition can ease the day-to-day
Slower digestion, constipation, easy dehydration, low energy and occasional nausea are frequently reported on GLP-1 medications. No supplement treats these, but a handful of nutrition basics — fibre, hydration, electrolytes and a few key vitamins — can make daily life more comfortable while your provider manages the medical side.
1. Fibre for digestion & regularity
Add fibre gradually to support regularity. A greens blend is an easy start when your appetite for whole vegetables is low — increase slowly and drink plenty of water.
2. Hydration & electrolytes
Eating and drinking less makes dehydration easy. Low-sugar electrolyte tablets or single-serve mixes in your water are a simple daily habit that supports hydration, energy and comfort.
3. Enzyme support for richer meals
When digestion is slowed, some people find enzyme capsules help them handle protein-rich or fatty meals more comfortably.
4. Fill the nutrient gaps
A smaller diet makes shortfalls in magnesium and B vitamins more likely. Targeted vitamins can help cover the gaps — alongside, not instead of, real food.

Frequently asked questions
- What helps with constipation on a GLP-1 medication?
- GLP-1 medications slow digestion, which can lead to constipation. Nutritionally, add fibre gradually (a greens blend or whole foods), drink plenty of water, keep electrolytes up, and stay physically active. Increase fibre slowly to avoid bloating. If constipation is severe or persistent, speak with your healthcare provider.
- Why do I feel dehydrated on Ozempic or Wegovy?
- When you eat and drink less, you also take in less fluid and fewer electrolytes, and some people experience nausea or looser stools that add to fluid loss. A low-sugar electrolyte tablet or mix in your water helps you stay hydrated, which can also support energy and comfort.
- Which electrolytes matter most, and how do I get them?
- Sodium, potassium and magnesium are the key ones for hydration and normal muscle and nerve function. Low-sugar electrolyte tablets or single-serve mixes make it easy to add them to water through the day. Choose low- or no-sugar options so you’re not adding unwanted calories.
- Can digestive enzymes help with nausea or heavy meals on a GLP-1?
- Some people find enzyme supplements help them digest protein-rich or fatty meals more comfortably when digestion is already slowed. Enzymes aren’t a treatment for nausea, and eating smaller, lower-fat meals and staying hydrated usually matters more. If nausea is significant, talk to your healthcare provider.
- Do I need a multivitamin or extra vitamins when eating less?
- Eating much less makes it easier to fall short on some nutrients, including magnesium and B vitamins. A greens blend and targeted vitamins can help fill gaps, but they don’t replace a balanced diet. A dietitian can tell you which, if any, you actually need.
En résumé (Français)
Les effets secondaires des GLP-1 (digestion lente, constipation, déshydratation, fatigue) sont fréquents. Aucun supplément ne les traite, mais quelques bases aident au quotidien : ajoutez des fibres progressivement, gardez une bonne hydratation avec des électrolytes faibles en sucre, envisagez des enzymes digestives pour les repas riches, et comblez les carences en magnésium et vitamines B. Buvez beaucoup d’eau. Information nutritionnelle générale, pas un avis médical.
