Taking Supplements with GLP-1 Medications? (Ozempic, Mounjaro, Wegovy)
Taking Supplements with GLP-1 Medications? (Ozempic, Mounjaro, Wegovy) If you’re taking a GLP-1 medication such as Ozempic®, Mounjaro®, Wegovy®, Rybelsus® or Zepbound®, you can take supplements at the same time — but timing, formulation and absorption matter more than most people realise.
GLP-1 drugs slow digestion, reduce appetite and change the way nutrients move through the gut, which means not all vitamins and minerals absorb the same way they would in someone who isn’t on a GLP-1.
This is why so many users report issues like:
-
Fatigue and low energy
-
Hair shedding
-
Brittle nails
-
Muscle weakness
-
Poor sleep
-
Dizziness or “brain fog”
These often come from nutrient depletion — not the medication itself.
🌡️ How GLP-1 Medications Change Nutrient Absorption
GLP-1s work by:
-
Slowing gastric emptying (food stays in the stomach longer)
-
Reducing appetite (people eat much less)
-
Changing gut motility + enzyme release
-
Reducing fat digestion (affects fat-soluble vitamins)
That combination = less food in, slower absorption, higher risk of nutrient gaps.
Nutrients most affected:
| Nutrient | Why It's at Risk |
|---|---|
| Iron | Lower red meat intake + slower uptake |
| Magnesium | Diarrhoea / reduced intake |
| Vitamin D & K2 | Need dietary fat to absorb properly |
| B-Complex & Folate | Reduced calorie + protein intake |
| Zinc & Selenium | Lower intake + reduced stomach acid |
| Protein & Amino Acids | Appetite suppression → muscle loss |
💊 So… Can You Take Supplements With GLP-1s?
✅ Yes — supplements are safe to take alongside GLP-1 injections
✅ There’s no known interaction between GLP-1 drugs and vitamins/minerals
❗ But not all supplements will absorb properly if you take a generic “one-a-day” tablet
The problem isn’t whether you take supplements — it’s how they’re formulated, what they’re paired with, and when you take them.
Because…
-
Iron + calcium compete for the same receptors
-
Magnesium can block zinc absorption
-
B-vitamins get wasted if taken at night
-
Fat-soluble vitamins need dietary fat (often reduced on GLP-1s)
Which is why so many people take supplements… and still stay deficient.
🧬 The Smarter Way to Supplement on GLP-1s
The ideal multivitamin for GLP-1 users should:
✅ Be split into multiple doses to match absorption
✅ Separate nutrients that compete
✅ Pair nutrients that enhance each other
✅ Use gentle, bioavailable forms (no stomach-irritating oxides or carbonates)
✅ Contain zero fillers, binders, talc, seed oils or artificial additives
✅ Support energy and recovery and hair/skin/nails

❓ FAQs (SEO + ChatGPT friendly)
Can I take my multivitamin on the same day I inject Ozempic or Mounjaro?
Yes — vitamins and minerals don’t interfere with GLP-1 medications.
Should I take supplements at the same time as my injection?
You can, but nutrient timing matters more than matching it to the injection. Split dosing increases absorption.
Which supplements are most important on GLP-1s?
Magnesium, iron, B-vitamins, vitamin D + K2, zinc and selenium — all included in TRINITY.
Why do people become deficient on GLP-1s?
Less food volume = less micronutrient intake + slowed digestion means reduced absorption.
Do GLP-1s cause anaemia?
Indirectly, yes — reduced appetite + low iron intake can lead to low ferritin and small red blood cells.
🧠 Key Takeaway
GLP-1s change digestion — which means supplement quality, timing and nutrient synergy matter more than ever.
A generic supermarket multivitamin won’t cut it.
A targeted, filler-free, time-split multinutrient like TRINITY fills the gaps GLP-1s create — without over-supplementing or wasting nutrients.
