The Nutrient Impact of GLP-1 Injections: What You Need to Know
GLP-1 receptor agonists like Ozempic (semaglutide), Mounjaro (tirzepatide), and Wegovy have become headline names in the world of weight loss. Designed to mimic the natural hormone glucagon-like peptide-1, these medications slow digestion, reduce appetite, and help regulate blood sugar — all of which support significant weight loss.
But as your appetite declines and meals become smaller, an unintended side effect can emerge: reduced intake of essential nutrients.
Let’s unpack the science — and explore how to maintain nutritional health on these powerful medications.
🧬 How GLP-1 Medications Work
GLP-1 receptor agonists affect the body in several key ways:
-
Delay gastric emptying – food stays in your stomach longer, so you feel fuller.
-
Reduce appetite – signalling the brain to eat less.
-
Enhance insulin secretion – helping regulate blood sugar levels.
While these effects support weight loss, they can also lead to lower food volume, which means fewer opportunities for vitamin and mineral intake.
⚠️ Potential Nutritional Deficiencies
Because many people on Ozempic or Mounjaro eat less (sometimes significantly so), they may not get enough of the following:
| Nutrient | Why It’s at Risk | Potential Effects of Deficiency | Support from Supplements? |
|---|---|---|---|
| Vitamin B12 | Reduced food intake, slower stomach acid production | Fatigue, nerve issues, mood changes | ✅ Found in TRINITY Morning |
| Folate (B9) | Decreased appetite, lower intake of leafy greens | Anaemia, fatigue, poor concentration | ✅ Found in TRINITY Morning |
| Magnesium | Not easily absorbed in low stomach acid environments | Muscle cramps, sleep disruption, low energy | ✅ TRINITY Night includes magnesium glycinate |
| Iron | Lower meat/legume intake and reduced stomach acidity | Anaemia, fatigue, pale skin | ✅ TRINITY Morning with vitamin C for enhanced absorption |
| Fat-Soluble Vitamins (A, D, E, K) | Reduced dietary fat impairs absorption | Immunity, bone, vision, skin issues | ✅ TRINITY Day contains Vitamins D, E & A in a time-specific blend |
🧠 Key Insight: These medications don’t block nutrient absorption directly — the risk comes from eating less food overall and from digestive changes.
🍽️ The Appetite Paradox: Less Food, Less Nutrition
Weight loss injections are effective partly because they cause early satiety (feeling full quickly). But this also means:
-
Meals are smaller and often less nutrient-dense
-
You might skip meals or forget to eat
-
You may crave fewer whole foods and more simple carbs due to altered hunger hormones
This creates a paradox: while you're losing weight, your body may also be slipping into mild nutritional insufficiency, especially if you're not supplementing appropriately.

💡 How to Support Nutritional Health on Ozempic or Mounjaro
If you're using GLP-1 medications for weight loss, consider the following tips:
✅ 1. Prioritise Nutrient Density
Focus your smaller meals on high-impact foods like:
-
Leafy greens, eggs, legumes
-
Lean proteins
-
Nuts and seeds
-
Oily fish
-
Colourful vegetables
✅ 2. Use a High-Quality Multi-Nutrient Supplement
A time-delivered formula like TRINITY Multi-Nutrients ensures your body receives vitamins and minerals across the day, even when food intake is low.
✅ 3. Monitor Bloods and Symptoms
Work with your healthcare provider to check for deficiencies in B12, iron, magnesium and others, especially if symptoms like fatigue, mood changes, or hair loss occur.
📌 Final Thoughts
GLP-1 medications like Ozempic and Mounjaro offer real hope in tackling obesity and metabolic dysfunction but they come with nutritional trade-offs. Eating less means absorbing less, and that’s where smart supplementation becomes essential.
TRINITY Multi-Nutrients, developed with nutrient synergy and timing in mind, supports the body during reduced food intake by enhancing absorption and filling key gaps — without overloading the body at once.
If you’re on a weight loss journey, don’t just think calories — think nutrients. Your body needs them more than ever.
