GLP-1 medications like Ozempic, Wegovy and Mounjaro have rapidly gained popularity for their effectiveness in managing type 2 diabetes and supporting weight loss. But while GLP-1 medications offer significant health benefits, they also come with nutritional considerations that shouldn’t be overlooked.

At Randox Health, we’re committed to helping you optimise every aspect of your wellbeing. If you’re currently taking or considering GLP-1 medications, it’s important to understand how it might affect your micronutrient levels and what you can do to maintain balance.


How GLP-1 medications work

GLP-1 (glucagon-like peptide-1) receptor agonists mimic the action of the natural GLP-1 hormone. They help regulate blood sugar by increasing insulin secretion, slowing stomach emptying and reducing appetite. These mechanisms not only improve glycaemic control but also contribute to significant weight loss.


Food Choices Matter 

While these medications are effective, they can reduce your intake of essential vitamins and minerals.

GLP-1 medications often curb appetite so effectively that individuals eat substantially less. Eating fewer foods means there’s an increased risk you won’t get as many nutrients as you need.

Because appetite decreases individuals are eating less of everything including protein, calcium, iron and vitamins.  Food is where we obtain most of our nutrients, so when someone eats less, nutrient deficiencies can develop.


Vital vitamins and minerals to watch

If you’re using or considering GLP-1 medications, monitoring and supporting your nutrient levels is essential. The following are particularly important:

  • Vitamin D
    Helps support bone health, immune function and insulin sensitivity. Vitamin D deficiency is common, especially in those with limited sun exposure or low dietary intake
  • Vitamin B12
    Critical for energy production, nerve function and red blood cell formation. A B12 deficiency can lead to fatigue, neurological issues and anaemia
  • Magnesium
    Involved in over 300 biochemical reactions in the body.

Take control of your health

To ensure you’re getting the nutrients you need while on GLP-1 medication, it’s vital to assess your current vitamin and mineral levels. At Randox Health, we offer a comprehensive Vitamin and Mineral blood test to identify any deficiencies and help you take proactive steps to support your health.


GLP-1 medications are transforming lives.   By staying informed and checking your micronutrient levels regularly, you can make the most of your treatment while safeguarding your long-term wellbeing.
