Supplements to Consider with Meds Like Ozempic and Mounjaro

Mounjaro

This article is for informational purposes only. Always consult your healthcare provider before adding any medications, supplements, or dietary changes to your prescribed regimen.

GLP-1 medications, such as Ozempic (semaglutide) and Mounjaro, are widely used for managing Type 2 diabetes and obesity. These medications can reduce appetite, which may lead to lower nutrient intake, especially if paired with a low-fat diet often recommended during treatment. While we don’t fully understand how these medications affect nutrient absorption, some evidence suggests they may impact levels of certain vitamins and minerals. Below, we outline seven supplements to consider, but always consult your healthcare provider to assess your needs through blood tests before starting any supplements.

Key Considerations

  • Nutrient Deficiencies: GLP-1 medications may reduce iron absorption and could contribute to lower levels of vitamins A, D, E, B12, magnesium, and potassium, particularly in individuals with obesity or Type 2 diabetes.
  • Dietary Impact: Reduced appetite and low-fat diets may increase the risk of deficiencies.
  • Avoid Certain Supplements: Do not take weight-loss supplements (e.g., ephedra, green tea extract, garcinia cambogia) or calcium supplements without medical approval, as they may pose risks when combined with GLP-1 medications.

Supplements to Discuss with Your Healthcare Provider

  1. Vitamin B12
    • Why it matters: Low B12 levels are linked to obesity and Type 2 diabetes, and a small study noted lower B12 in semaglutide users post-weight-loss surgery. B12 supports energy and metabolism.
    • Sources: Beef, poultry, dairy, or OTC/prescription supplements.
    • Note: Your provider will determine the appropriate form and dose.
  2. Iron
    • Why it matters: Iron deficiency is common globally, and GLP-1 medications may reduce iron absorption, increasing the risk of anemia.
    • Sources: Red meat, seafood, dark poultry, beans, seeds, leafy greens.
    • Note: Excess iron can be harmful, so only take supplements if prescribed after testing.
  3. Fiber
    • Why it matters: Only 5% of U.S. adults meet fiber recommendations, and reduced appetite from GLP-1 medications may worsen this. Fiber supports digestion and overall health.
    • Sources: Whole grains, beans, lentils, nuts, seeds, fruits, vegetables, or OTC supplements like psyllium (Metamucil).
    • Note: Increase fiber gradually to avoid digestive issues.
  4. Vitamin D
    • Why it matters: About 25% of people have low vitamin D, with higher risks in obesity and Type 2 diabetes. It supports bone health, immunity, and sugar metabolism.
    • Sources: Fatty fish, fortified cereals, dairy, or OTC/prescription supplements.
    • Note: Too much vitamin D is toxic, so only take as prescribed.
  5. Vitamins A & E
    • Why it matters: These fat-soluble vitamins are often low in obesity and Type 2 diabetes, and low-fat diets may reduce absorption. Vitamin A supports vision and immunity; vitamin E is an antioxidant.
    • Sources: Carrots, sweet potatoes, spinach (A); nuts, seeds, vegetable oils (E).
    • Note: Excess can be harmful, so confirm need and dosage with your provider.
  6. Magnesium
    • Why it matters: Low magnesium is common in Type 2 diabetes and may occur with GLP-1 medications due to side effects like vomiting or diarrhea. It supports blood pressure, blood sugar, and nerve function.
    • Sources: Nuts, whole grains, leafy greens, or OTC supplements.
    • Note: Excess magnesium can cause diarrhea or heart issues, so consult your provider.
  7. Potassium
    • Why it matters: Vomiting from GLP-1 medications or diabetes may lower potassium, which is vital for heart and muscle function.
    • Sources: Avocados, beans, raisins, or OTC/prescription supplements.
    • Note: Too much potassium can cause serious heart issues, so only take as prescribed.

Should You Take a Multivitamin?

A balanced diet is the best way to get nutrients. However, if you follow a restrictive diet (e.g., vegan or vegetarian) or struggle to eat enough nutrient-rich foods, a multivitamin may help. Always check with your healthcare provider to confirm it’s safe and necessary.

Supplements to Avoid on Ozempic, Mounjaro, Etc..

  • Weight-loss supplements: These may increase appetite suppression or nutrient deficiency risks and lack safety data with GLP-1 medications.
  • Calcium: GLP-1 medications may elevate calcium levels, so avoid supplements unless your provider confirms they’re safe.

The Bottom Line

While GLP-1 medications like Ozempic and Mounjaro are effective for weight management and diabetes, they may affect nutrient levels due to reduced appetite or side effects like vomiting and diarrhea. Focus on a nutrient-rich diet with adequate fiber, and work with your healthcare provider to monitor nutrient levels and determine if supplements are necessary. Never start supplements without medical guidance, as some can cause harm.
