## Direct 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.

## Quick facts

- Active ingredient: semaglutide
- Drug class: GLP-1 receptor agonist
- Maker: Novo Nordisk
- Approved for: Type 2 diabetes (used off-label for weight management)
- Dosing: Once-weekly subcutaneous injection, titrated 0.25 mg → 0.5 mg → 1 mg → 2 mg
- Active ingredient: Semaglutide
- Class: GLP-1 receptor agonist
- Dosing: Once weekly, subcutaneous
- Typical appetite reduction: 30–40% fewer calories
- Most common complaint: Nausea and constipation
- Top supplement priority: Protein + electrolytes

## Supplement priorities

- Protein (0.7–1.0 g per pound of goal body weight daily, split across 2–3 servings): Semaglutide cuts food intake 30–40%, and 25–40% of the weight lost can be lean muscle when protein intake falls short.
- Electrolytes (sodium, potassium, magnesium) (1–2 servings daily, more on dose-escalation weeks): Reduced thirst plus lower food volume strips sodium and potassium, which drives most of the fatigue, headaches, and cramps blamed on the drug.
- Magnesium glycinate (200–400 mg, 30–60 minutes before bed): Supports sleep quality, muscle relaxation, and bowel regularity while gastric emptying is slowed.
- Soluble fiber (5–10 g daily, at least 2 hours away from prescription medication): Constipation is the most persistent GI complaint on semaglutide; soluble fiber softens stool when paired with fluid.
- B-complex + vitamin D3/K2 (Once daily with your largest meal): Smaller plates mean fewer micronutrients; B12, folate, and vitamin D are the most common gaps on long-term treatment.

## Side-effect playbook

- 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.

## FAQ

### What supplements should I take with Ozempic?

Protein, electrolytes, magnesium glycinate, soluble fiber, and a B-complex with vitamin D3/K2 cover the five gaps Ozempic creates: muscle retention, hydration, sleep and regularity, digestion, and micronutrients.

### Do supplements interfere with Ozempic?

Standard protein, electrolyte, vitamin, and magnesium products do not interfere with semaglutide. Take fiber and mineral supplements at least two hours apart from oral prescription medication, and check any new supplement with your prescriber.

### Why am I so tired on Ozempic?

Fatigue on Ozempic is usually a calorie, protein, or electrolyte shortfall rather than the drug itself. Hit your protein target, add sodium and potassium, and ask for ferritin, B12, and vitamin D labs if it persists past a few weeks.

### How do I stop constipation on Ozempic?

Combine 5–10 g of soluble fiber, 200–400 mg magnesium glycinate at night, an extra 16–24 oz of fluid daily, and daily movement. This resolves most Ozempic-related constipation within a week.

### Will I lose muscle on Ozempic?

You can lose 25–40% of total weight as lean mass if protein is low and you do not train. Eating 0.7–1.0 g of protein per pound of goal weight and lifting 2–3 times per week keeps most of that muscle.
