Can I take supplements while on Ozempic?
Yes, but specific ones require caution or physician guidance. The supplements with the highest safety profile on Ozempic are: vitamin B12 (methylcobalamin), magnesium glycinate, vitamin D3+K2, omega-3 fish oil, and creatine monohydrate. The supplements to avoid or use with physician guidance are: berberine, gymnema, bitter melon (blood glucose interaction), and high-dose viscous fiber (worsens constipation). Discuss with your prescribing physician before starting any supplement.
What vitamins are depleted by GLP-1 medications?
GLP-1 medications don't directly deplete specific vitamins in the same way as metformin (which specifically depletes B12 via a known mechanism). The primary nutritional risk from GLP-1 therapy is reduced intake due to profound appetite suppression — you are eating far less, so you are absorbing less of everything. The nutrients most at risk are: vitamin B12 (also affected by gastric emptying slowing and, if co-prescribed, metformin), vitamin D (fat-soluble, at risk if fat intake is very low), magnesium (widely deficient in type 2 diabetes populations and worsened by reduced intake), and calcium (bone health concern on rapid weight loss). Iron and folate deficiency have also been reported in clinical practice.
Is it safe to take creatine with Wegovy?
There is no known pharmacological interaction between creatine and semaglutide (Wegovy). Creatine operates at the skeletal muscle level; Wegovy operates at GLP-1 receptors. The main practical considerations are: use maintenance dose 5g/day (not loading) to avoid compounding GI effects; inform your physician if kidney function is tested (creatine raises serum creatinine); confirm with your physician that your baseline kidney function is appropriate for supplementation if you have diabetes with any kidney involvement.
What form of B12 should I take on Ozempic?
Methylcobalamin is preferred over cyanocobalamin for people on GLP-1 medications. Cyanocobalamin requires stomach acid and intrinsic factor for absorption from the gut — both of which may be functionally reduced when gastric emptying is slowed. Methylcobalamin is already in the bioactive form and is absorbed via passive diffusion in high doses, bypassing the intrinsic factor requirement. Sublingual methylcobalamin (dissolves under the tongue) at 1,000mcg daily is a practical first choice. If you are also on metformin, your deficiency risk is higher and your physician may recommend testing B12 levels.
What should I NOT take with Mounjaro or Zepbound?
The main supplements to avoid with tirzepatide (Mounjaro or Zepbound) without physician guidance are: berberine (significant additive hypoglycemia risk), gymnema sylvestre (insulin secretagogue, additive glucose-lowering), bitter melon (same), high-dose fenugreek extract (mild but real glucose-lowering effect). Also: vitamin K2 MK-7 if you are on anticoagulants. High-dose viscous fiber supplements (psyllium, glucomannan) should be used cautiously — they can worsen constipation, already a common tirzepatide side effect.
