GLP-1 medications like Ozempic, Wegovy, and Mounjaro have revolutionized weight management for millions of people. By reducing appetite and slowing gastric emptying, these drugs help patients achieve significant weight loss. However, this same mechanism creates a hidden challenge: nutritional deficiencies.
When you eat less, you naturally consume fewer vitamins and minerals. Combined with changes in how your body absorbs nutrients, GLP-1 users face specific nutritional gaps that need attention.
The Most Common Nutrient Deficiencies in GLP-1 Users
1. Vitamin B12
Vitamin B12 deficiency is one of the most well-documented concerns for GLP-1 medication users. These drugs slow gastric emptying and alter stomach acidity, which affects B12 absorption. B12 is critical for energy production, nervous system function, red blood cell formation, and cognitive health. Signs of deficiency include fatigue, weakness, numbness or tingling, memory problems, and mood changes.
2. Iron
Reduced food intake often means reduced iron consumption, particularly from animal sources. Additionally, changes in stomach acidity can affect iron absorption. Iron is essential for oxygen transport throughout the body, energy metabolism, and immune function. Signs of deficiency include fatigue, pale skin, shortness of breath, cold hands and feet, and brittle nails.
3. Vitamin D
Many Canadians are already vitamin D deficient, especially during winter months. Reduced food intake can further decrease vitamin D consumption. Vitamin D supports bone health, immune system function, and muscle function.
4. Calcium
With reduced appetite often comes reduced dairy consumption. Calcium is crucial for bone density and strength, muscle contraction, and nerve transmission.
5. Magnesium
Magnesium is found in nuts, seeds, leafy greens, and whole grains. This mineral is vital for over 300 biochemical reactions in the body, muscle and nerve function, blood sugar control, and blood pressure regulation.
6. Thiamine (Vitamin B1)
Thiamine is critical for energy metabolism and nervous system function. The body stores very little thiamine, so deficiency can develop quickly with reduced intake.
7. Zinc
Zinc is commonly found in protein-rich foods like meat, seafood, and legumes. With reduced protein intake, zinc deficiency can occur. Zinc is necessary for immune function, wound healing, protein synthesis, and sense of taste and smell.
8. Folate (Vitamin B9)
Folate is found in leafy greens, legumes, and fortified grains. Folate is important for DNA synthesis and cell division, red blood cell formation, and neural health.
How to Address Nutritional Gaps
Prioritize nutrient-dense foods like lean proteins, leafy greens, nuts, seeds, and fortified dairy. Consider a quality multivitamin specifically formulated to address these nutritional gaps. Work with your healthcare provider to monitor nutrient levels regularly.
