It sounds like the protein powder may be causing your digestive symptoms like loose motions and vomiting.

🩺 What This Likely Means

These symptoms could be due to intolerance or mild sensitivity to an ingredient in the protein powder, such as artificial sweeteners, flavorings, or lactose if using milk. Sometimes starting a new supplement can upset the stomach temporarily.

🏥 What You Should Do

• Stop taking the protein powder for now to see if symptoms improve.
• Stay hydrated, especially if you have loose motions or vomiting.
• If you want to try again, start with a smaller amount and take it with plain water rather than milk.
• Avoid other new foods or supplements until symptoms resolve.
• If symptoms persist beyond 2 days, worsen, or you develop signs of dehydration (dizziness, very little urine), seek prompt evaluation.

🩺 When to See a Doctor

Consult a gastroenterologist or your primary care doctor if symptoms continue or worsen despite stopping the powder, to rule out other causes and get tailored advice.
