Most people don’t start GLP‑1 medication thinking about supplements.
They start because they want weight loss, health improvement, and a calmer relationship with food.
But once appetite drops, a new problem appears:
You can’t get nutrition from food you’re no longer eating.
This page explains what supplements can realistically help GLP‑1 users — and which ones are usually just expensive optimism.

TL;DR: the only “supplement categories” that matter on GLP‑1s
If you’re going to simplify this, focus on:
- Protein (muscle retention + energy)
- Fibre (motility + satiety + constipation prevention)
- Gut support (comfort + regularity)
- Micronutrient coverage (insurance during low intake)
This is the logic behind the Daily Essentials Bundle concept.
Real‑world context: why I care about this
In 2025 I lost over 6 stone (86lbs) using Mounjaro.
I had most common GLP‑1 side effects at some point, and the biggest learning was this:
You don’t need perfect optimisation. You need a baseline system.

Why appetite suppression creates nutritional risk
When appetite drops: – Food variety drops – Fibre intake usually drops – Protein becomes harder to prioritise – Micronutrients become inconsistent
It’s not because people are lazy.
It’s because GLP‑1s change eating behaviour at a biological level.

“What helps” vs “what’s hype” (simple table)
| Category | Often helpful on GLP‑1 | Why | Usually hype when |
| Protein | Yes | Helps muscle retention + energy | Used instead of meals long-term |
| Fibre | Yes | Helps constipation + motility | Taken in bursts without hydration |
| Probiotics | Sometimes | May help gut comfort | Used as a cure-all |
| Omegas | Sometimes | Supports general health | Used for weight loss claims |
| Fat burners | No | Stimulant marketing | Always |
| Detox | No | Not evidence-led | Always |
The daily routine that makes supplements work
Supplements don’t work in isolation.
They work when the routine is stable:
| Routine piece | Why it matters |
| Hydration | Prevents constipation + fatigue |
| Protein-first meals | Prevents muscle loss + crashes |
| Consistent fibre | Keeps motility stable |
| Gentle daily movement | Supports digestion |

FAQs
Do I need supplements on Mounjaro?
Not always. But many people struggle to hit protein, fibre, and micronutrients early on due to reduced appetite.
What’s the best supplement for GLP‑1 constipation?
Hydration + consistent fibre + movement usually beats random products. A daily baseline is often more effective than “as needed” fixes.
Can supplements replace food on GLP‑1s?
No. Supplements work best as support, not replacements.
Is Lily & Loaf a fat burner?
No. The Daily Essentials approach is positioned as daily nutrition support rather than stimulant-driven weight loss.
