What are the best supplements for Wegovy?

Protein, an electrolyte blend, magnesium glycinate, soluble fiber, and a B-complex with vitamin D3/K2. These five address muscle loss, dehydration, sleep, constipation, and the micronutrient gaps that appear at the 1.7–2.4 mg doses.

Does Wegovy cause hair loss?

Wegovy does not directly cause hair loss. Rapid weight loss triggers telogen effluvium, a temporary shedding phase. Adequate protein, iron, zinc, and vitamin D — plus slower weight loss — shorten it.

How much protein do I need on Wegovy?

Aim for 0.7–1.0 g of protein per pound of goal body weight, which for most adults lands between 100 and 150 g per day. Split it across two or three servings because appetite is lowest right after your injection.

What should I take during a Wegovy dose increase?

Double electrolytes for three days, keep protein liquid, eat smaller and lower-fat meals, and take magnesium glycinate at night. Most escalation symptoms fade within 72 hours.

Wegovy (semaglutide 2.4 mg): nutrition and supplement hub

Updated July 31, 2026Reviewed by the Elevate GLP nutrition team

Short answer

Wegovy is semaglutide dosed for weight management, titrated to 2.4 mg weekly. At maintenance dose most users eat 35–50% less, so protein, electrolytes, magnesium, fiber, and a daily multivitamin matter more than on lower diabetes doses. Prioritise protein and resistance training to limit lean-mass loss, and step up electrolytes during each titration increase.

Supplement priorities on Wegovy

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.
