From the research

What vitamins are you deficient in on GLP-1?

Every GLP-1 journey is different. The nutrient gaps are not.

The most commonly documented deficiencies in GLP-1 patients are vitamin B12, vitamin D3, magnesium, and iron. These gaps emerge because appetite suppression reduces total food intake, and slower gastric emptying reduces B12 absorption specifically. Research shows up to 22% of GLP-1 patients become newly deficient within 12 months.

Common questions

What patients ask about GLP-1?

What vitamins should I take on Ozempic?
People on Ozempic most commonly become deficient in vitamin B12, magnesium, vitamin D3, and iron. These gaps open because appetite suppression reduces total food intake and GLP-1 drugs slow gastric emptying, which can reduce absorption. A protocol targeting these four nutrients - plus omega-3 and zinc - covers the deficiency patterns seen most frequently in clinical studies.
Does GLP-1 medication cause nutrient deficiency?
Indirectly, yes. GLP-1 medications like Ozempic, Wegovy, and Mounjaro reduce appetite significantly, so patients eat fewer calories and take in fewer vitamins and minerals. Slower gastric emptying can also reduce absorption of B12 and other nutrients. Research shows B12, magnesium, iron, and vitamin D are the most commonly affected.
How do you prevent muscle loss on GLP-1 medication?
GLP-1 medications reduce appetite effectively, but they do not distinguish between fat and muscle when the body is in a calorie deficit. Studies show that a significant proportion of weight lost on GLP-1 drugs can come from lean mass. The evidence-backed approach involves adequate protein intake, resistance training, and targeted supplementation - particularly magnesium and omega-3, which support muscle protein synthesis.
What is GLP-1 Shield and how does it work?
GLP-1 Shield is a phase-adaptive supplement protocol designed specifically for people on GLP-1 medications. It identifies which nutrients your reduced intake is leaving behind and delivers a targeted formula that changes as your journey progresses - from early titration through deep weight loss and into long-term maintenance.
How is GLP-1 Shield different from a standard multivitamin?
Standard multivitamins are designed for people eating a normal diet. GLP-1 patients face a specific combination of reduced intake plus altered absorption - so the gaps are different in type, size, and timing. GLP-1 Shield is formulated around the deficiency patterns clinically documented in GLP-1 patients, and adapts to your phase rather than delivering a static one-size-fits-all dose.
