Anaemia on Ozempic, Mounjaro or Wegovy? Understand the Risk & How to Prevent It

Are You at Risk of Anaemia on Mounjaro, Ozempic or Wegovy? Here’s What You Need to Know

GLP-1 medications such as Ozempic® (semaglutide), Mounjaro® (tirzepatide) and Wegovy are highly effective for weight loss and metabolic health. But with reduced appetite comes another, less discussed risk: iron deficiency and anaemia.

If you’ve been feeling more tired than usual, getting dizzy, or struggling with low motivation on your medication — it may not just be side effects. It could be a sign of underlying iron deficiency.

Let’s break down how this happens — and what you can do to support healthy iron levels while on GLP-1 therapy.

🔬 What Is Iron Deficiency Anaemia?

Iron deficiency anaemia occurs when your body doesn't have enough iron to produce adequate haemoglobin — the oxygen-carrying component of red blood cells. Without enough haemoglobin, your cells don’t get enough oxygen, leading to:

  • Fatigue and weakness

  • Shortness of breath

  • Pale skin or dark under-eyes

  • Dizziness or light-headedness

  • Brain fog or poor concentration

  • Cold hands and feet

⚠️ Why Ozempic and Mounjaro Users May Be at Risk

Several factors contribute to low iron status in people taking GLP-1 medications:

1. Reduced Appetite = Lower Iron Intake

GLP-1s suppress hunger significantly. As food intake drops, so does consumption of iron-rich foods — especially red meat, legumes, leafy greens, and fortified grains.

2. Less Meal Diversity

Some users on Ozempic or Mounjaro tend to simplify their meals to avoid nausea or discomfort — often favouring toast, crackers, or small snacks. These lack the nutritional density needed to support iron levels.

3. Menstruation + Weight Loss = Increased Demand

People who menstruate are already more prone to iron deficiency. Combine that with rapid weight loss or changes in hormone levels, and the risk of anaemia increases further.

4. Poor Nutrient Absorption

GLP-1 drugs slow gastric emptying — and in some people, this affects mineral absorption. If meals are smaller and digestion is slower, iron may not be absorbed effectively, especially if taken alongside calcium or caffeine.

🔍 What Kind of Iron Should You Look For?

Not all iron supplements are created equal. Many common multivitamins use ferrous sulphate, which is hard on the stomach and poorly absorbed.

The gold standard for absorption and gentleness is iron bisglycinate — a chelated form that’s both bioavailable and gentle on digestion, even for sensitive users.

🌿 How TRINITY Helps Support Iron & Prevent Anaemia

TRINITY by Arbor Vitamins includes a targeted, time-optimised Morning Formula that delivers:

  • Iron (Ferrous Bisglycinate) — highly absorbable and non-constipating

  • Vitamin C (Ascorbic Acid) — enhances iron absorption by up to 300%

  • B-complex vitamins (B6, B12, Folate) — essential for red blood cell production

  • Magnesium malate and turmeric — reduce inflammation and support oxygen delivery

This blend is taken in the morning, when your body is most active and needs support for energy metabolism and mental focus.

💡 Unlike one-a-day multivitamins, TRINITY separates iron from calcium and other competing nutrients to avoid absorption conflicts.

✅ Why It Works for GLP-1 Users

  • Designed for low-appetite lifestyles

  • Gentle on the stomach — no binders or synthetic fillers

  • Vegan-friendly and gut-conscious

  • Supports daily energy, oxygen transport, and nutrient synergy

🧠 Summary: Don’t Let Anaemia Undermine Your Progress

Fatigue isn’t always “just a side effect.” If you’re on Ozempic, Mounjaro, or another GLP-1 and you’re feeling drained, it’s worth checking your iron status — and making sure your multivitamin is actually helping, not hindering.

TRINITY delivers a clean, clinically thoughtful solution that supports red blood cell health, energy levels, and nutrient absorption — all in a time-of-day format designed for how your body truly works.

✅ Key Takeaways

  • GLP-1 users may be at risk of anaemia due to reduced food intake, poor absorption, and low iron-rich meals

  • Symptoms like fatigue, dizziness, and brain fog may be signs of iron deficiency

  • TRINITY includes iron bisglycinate + vitamin C and B-complex — optimised for absorption and energy
