Ozempic (semaglutide): nutrition and supplement hub
Short answer
Ozempic is once-weekly semaglutide, a GLP-1 receptor agonist that slows gastric emptying and reduces appetite. Because food intake typically falls 30–40%, the highest-value support is protein (0.7–1.0 g per pound of goal weight), electrolytes, magnesium glycinate at night, 5–10 g of soluble fiber, and a B-complex with vitamin D. Supplements do not change how Ozempic works — they replace the nutrients smaller meals no longer supply.

Supplement priorities on Ozempic
1. Protein
Semaglutide cuts food intake 30–40%, and 25–40% of the weight lost can be lean muscle when protein intake falls short.
Typical dose: 0.7–1.0 g per pound of goal body weight daily, split across 2–3 servings
2. Electrolytes (sodium, potassium, magnesium)
Reduced thirst plus lower food volume strips sodium and potassium, which drives most of the fatigue, headaches, and cramps blamed on the drug.
Typical dose: 1–2 servings daily, more on dose-escalation weeks
3. Magnesium glycinate
Supports sleep quality, muscle relaxation, and bowel regularity while gastric emptying is slowed.
Typical dose: 200–400 mg, 30–60 minutes before bed
4. Soluble fiber
Constipation is the most persistent GI complaint on semaglutide; soluble fiber softens stool when paired with fluid.
Typical dose: 5–10 g daily, at least 2 hours away from prescription medication
5. B-complex + vitamin D3/K2
Smaller plates mean fewer micronutrients; B12, folate, and vitamin D are the most common gaps on long-term treatment.
Typical dose: Once daily with your largest meal
Side-effect playbook
| Symptom | What to do |
|---|---|
| Nausea | Eat smaller, cooler, lower-fat meals; sip ginger or peppermint tea; keep protein liquid for 24–48 hours after your dose. |
| Constipation | Add 5–10 g soluble fiber, 200–400 mg magnesium glycinate at night, and increase fluid by 16–24 oz per day. |
| Fatigue | Check protein and calories first, then electrolytes. Persistent fatigue with hair shedding warrants ferritin, B12, and vitamin D labs. |
| Muscle loss | Hit your protein target daily and lift 2–3 times weekly. Resistance training is the only intervention that reliably preserves lean mass. |
| Hair shedding | Usually telogen effluvium from rapid weight loss, not the drug. Support with adequate protein, iron, zinc, and biotin-containing B-complex. |
| Leg cramps | Almost always sodium, potassium, or magnesium. Add an electrolyte serving mid-afternoon and magnesium at night. |
