Taking Vitamins and Supplements While on GLP-1 Medications
GLP-1 (glucagon-like peptide-1) medications have gained popularity for their ability to help manage type 2 diabetes and support weight loss.[1] Learn how GLP-1 medications work, their role in weight loss and whether supplements can support a healthy diet while taking these medications.

How Do GLP-1 Medications Help with Weight Loss?
GLP-1 medications work by mimicking the GLP-1 hormone produced by the small intestine that helps trigger insulin release to help manage blood sugar.[1] These medications are typically used to treat type 2 diabetes and obesity.[1] When it comes to weight loss to help with obesity, GLP-1 medications can slow digestion and increase satiety, helping you feel fuller longer and potentially reducing your overall consumption.[1] This process contributes to weight loss, especially when paired with lifestyle changes like diet and exercise.[1]
Research on GLP-1 Medications and Supplements
Research shows that GLP-1 medications can contribute to lower food intake and cause patients to eat fewer calories overall.[2] As these medications can cause you to eat less, it’s important to consume nutrient-rich foods to ensure you are meeting your micronutrient needs.[2] As a result, some patients may benefit from supporting a balanced diet with additional vitamin supplementation.[2] Ask your healthcare practitioner for guidance on how to maintain proper nutrition while losing weight.[2]
Before taking any supplements with your GLP-1 medication, consult with your healthcare practitioner to find the best course of action.[2] When considering supplements, it's important to view them as supporting a healthy diet rather than replacing nutrients.
Nutrition and Dietary Needs on a GLP-1
Individuals who take GLP-1 medications often reduce their food intake.[2] This means that the quality of their diet is more important as they need to meet their nutritional needs with fewer calories.[2] Experts suggest eating a balanced diet of nutrient-dense foods while using GLP-1 medications.[2] Examples of nutrient-dense foods include vegetables, fruits, whole grains, seafood, eggs, legumes, unsalted nuts and seeds, low-fat dairy products and lean meats.[2]
Essential Nutrients
Those who struggle with obesity may have trouble getting the micronutrients they need.[3] Here are some nutrients that are essential for your health:[3]
- Vitamin A: This nutrient is essential for immune function and normal vision. It’s necessary for cell growth and development.
- Thiamin (Vitamin B1), Riboflavin (Vitamin B2), Biotin (Vitamin B7) and Niacin (Vitamin B3): These nutrients help release energy from fat, carbohydrates and protein.
- Pantothenic Acid: This nutrient also assists in the release of energy from fat, carbohydrates and protein but also assists fat, cholesterol, steroid hormones and hemoglobin synthesis.
- Vitamin B6: Supports metabolic reactions and assists neurotransmitters, hemoglobin and DNA production.
- Vitamin C: This nutrient is an antioxidant in blood cells and assists with collagen, serotonin, carnitine and adrenaline production.
- Vitamin D: Promotes bone health, immune function and maintains calcium and phosphorous balance.
- Vitamin E: Acts as an antioxidant in cell membranes and supports normal nerve function.
Remember that while supplementation can be used to support nutrition, it should enhance a balanced diet, not replace it.[2] Consult with a healthcare provider before adding new supplements to your routine if you’re using GLP-1 medications.
GLP-1 medications can support weight loss and blood sugar management, but their benefits are best realized when combined with healthy lifestyle choices.[1] Vitamin supplements can complement your diet while taking GLP-1 medications, but they should be seen as supportive rather than replacing nutrients from food.[2] Always consult with a healthcare provider before making changes to your supplement regimen to ensure they fit your health needs.
