💉 Side Effects of Ozempic, Mounjaro & Other GLP-1 Injections: Nutrient Gaps & How to Support Your Health
Side Effects of Ozempic and GLP-1 receptor agonists — including Ozempic® (semaglutide), Mounjaro® (tirzepatide), Wegovy®, Rybelsus®, and Zepbound® — are helping thousands of people in the UK and worldwide to lose weight and manage type 2 diabetes.
By slowing digestion, reducing hunger hormones, and increasing feelings of fullness, they can lead to significant health improvements. But alongside the benefits, some people experience side effects — and a few of these may be linked to reduced nutrient intake over time.
⚠️ Common Side Effects of GLP-1 Injections
While everyone’s experience is different, these are the side effects most often reported:
-
Digestive Changes
-
Nausea, vomiting, diarrhoea, constipation, bloating or heartburn.
-
Can lead to reduced appetite and food variety.
-
-
Headaches & Dizziness
-
May be linked to hydration changes, low blood sugar, or nutrient imbalances.
-
-
Hair Thinning or Shedding
-
Often occurs after rapid weight loss or insufficient intake of key nutrients such as protein, iron, zinc, and biotin.
-
-
Fatigue & Low Energy
-
Can be due to lower calorie intake and reduced levels of B-vitamins, magnesium, and iron.
-
-
Muscle Weakness or Cramps
-
Magnesium, potassium, and calcium shortfalls may contribute.

🧬 Why Nutrient Deficiencies Can Happen on GLP-1s
GLP-1 medications don’t “steal” nutrients — but they can change how much you consume and absorb:
-
Smaller meals & fewer snacks → less chance to hit daily nutrient targets.
-
Low-fat eating → reduced absorption of vitamins A, D, E, and K.
-
Nausea or diarrhoea → minerals like magnesium, zinc, and potassium can be lost more quickly.
-
Selective eating → if you avoid certain food groups, key micronutrients may be missed entirely.
🥗 Nutrients Worth Paying Attention To
| Nutrient | Why It Matters | Risk on GLP-1s |
|---|---|---|
| Magnesium | Sleep, nerve health, muscle function | Reduced intake + diarrhoea losses |
| Iron | Energy, oxygen transport | Less red meat + lower absorption |
| B12 & Folate | Brain health, energy, red blood cells | Low intake from smaller meals |
| Vitamin D & K2 | Bone health, calcium balance, immune support | Fat-soluble + low-fat diets |
| Zinc & Selenium | Hair, skin, thyroid, immunity | Reduced intake and absorption |
| B-Complex | Energy, cognition, metabolism | Depleted on low-calorie diets |
🌿 Why a Good Multivitamin Can Help
If you’re eating less overall, a quality multivitamin can help cover the gaps — provided it’s:
-
Bioavailable (uses nutrient forms your body can absorb easily)
-
Free from unnecessary fillers or binders
-
Timed so competing nutrients don’t block each other’s absorption
