Friendly, clear advice for real life — your guide to staying healthy and supported while taking
GLP-1 medications.
Why this matters
If you’re taking a GLP-1 medication (like injections for weight loss or diabetes), you’re already doing something big for your health. But here’s the thing: because these medications change how your body handles food, appetite and nutrients, they can also make you more likely to miss out on vitamins, minerals and proper nutrition. It’s not just about losing weight — it’s about staying strong, feeling good and getting results safely. In this article, we’ll answer what many people ask:
What vitamins should I take while taking GLP-1?
What vitamins/supplements should I take with weight-loss injections?
What supplements should I take with tirzepatide?
What supplements should I take when on Mounjaro?
How to maximize GLP-1 results?
And yes — we’ll include easy meal plans and recipes for people taking Tirzepatide (brand name Mounjaro) or other GLP-1 medications. Plus, a friendly call to action so you know exactly what to do next.
What vitamins should I take while taking GLP-1?
When you’re on a GLP-1 medication, you might eat less (or feel less hungry). That’s great for weight loss, but it also means you might get fewer nutrients naturally. Experts say you may need extra support.
Here are key nutrients to pay attention to:
Vitamin B12 – Some articles suggest considering 500–1000 mcg if you’re on long-term GLP-1 therapy.
Vitamin D + Calcium – Important for strong bones, especially when your food intake drops.
Magnesium – Helps muscles, nerves and overall energy conversion. Found in some “GLP-1 companion” multivitamin packs.
Fiber – Not exactly a vitamin, but really important. It helps digestion and supports gut health — especially since GLP-1 meds may slow digestion.
General multivitamin/mineral support – Because when you eat less, you might miss a bunch of smaller nutrients (vitamins A, C, E, etc.)
Bottom line: Yes — you should consider taking vitamins/supplements while on a GLP-1, but only as a support to a good diet, and always in consultation with your doctor.
What Vitamins/Supplements Should I Take with Weight-Loss Injections?
If by “weight-loss injections” you mean GLP-1 medications (like semaglutide, tirzepatide, etc.), then yes — many of the same nutrient concerns apply: fewer calories, appetite changes, slower digestion, possible side effects (like nausea or constipation).
Here are some top picks:
A multivitamin/mineral supplement designed for people who eat less or are losing weight.
Extra focus on B12, D, calcium, magnesium as listed above.
Include fiber + probiotics/prebiotics to help digestion and gut health (which may be challenged).
Pay attention to protein: when you lose weight fast, you risk losing muscle. So a higher-protein diet helps.
Warning: Not all supplements are safe or helpful. Some may interfere with how your medications work or cause side-effects. For instance, chromium or high-dose zinc may be problematic.
What Supplements Should I Take With Tirzepatide?
Tirzepatide (brand Mounjaro) is a newer medication that works on GLP-1 pathways (and more). So the support strategy is very similar to any GLP-1 med, but you may have even stronger effects (less hunger, more weight loss) so nutrient support becomes even more important.
Focus on:
A high-quality multivitamin/mineral that covers your bases.
B12, D + calcium, magnesium.
Adequate protein and fiber.
Ensuring you’re drinking enough water (because some GLP-1 meds reduce thirst or make you less hungry for fluids).
Again: make sure you talk to your doctor before adding or changing any supplement.
What Supplements Should I Take When On Mounjaro?
If you’re taking Mounjaro (tirzepatide), here’s your checklist:
Multivitamin/mineral designed for weight-loss support (to fill the gaps)
Vitamin B12
Vitamin D + Calcium
Magnesium
Fiber and probiotics for digestive balance
Adequate water (target ~80-100 oz/day depending on your size and doctor’s advice)
Good quality protein and whole food meals — see the meal plan below
How to Maximize GLP-1 Results?
Taking your medication is step one. Now you want to maximize the results — meaning greater weight loss (if that’s your goal), better health outcomes, lean muscle, good nutrition. Here’s how:
Stay consistent with your medication and follow your healthcare provider’s plan.
Eat enough protein + fiber, even if you’re eating less overall — helps prevent muscle loss and supports fullness.
Stay hydrated — GLP-1 meds can reduce thirst signals, so you might not feel thirsty but still need fluids.
Fill nutrient gaps with the right vitamins/supplements (see sections above).
Move your body (strength + cardio) — muscle supports metabolism, helps with weight loss and keeps you strong.
Choose smart meals (see our meal plan below).
Listen to your body for side-effects (nausea, constipation) and manage them with diet, fiber, hydration, and your provider’s advice.
