Preventing nausea from protein shakes may require some detective work to learn what's triggering your queasiness. Cutting calories excessively, pregnancy, food poisoning, lactose intolerance, food allergies, exercise and certain medical conditions, medications or medical treatments can cause nausea. Some people experience queasiness when they take vitamins or supplements. If there isn't a problem with the protein shake, using a natural remedy can help prevent nausea. Consult your doctor about nausea, as it could be a sign of a medical condition.

Read the label. Check the ingredients, the serving size, the amount of protein per serving, the carbohydrates and sugar per serving and the amounts of any added vitamins or supplements. For example, if the protein shake has 27 g of protein and you're sedentary and ingest other protein sources, you may be consuming too much protein. Examine the supplement content. If you take daily vitamins, you may be getting too much of some vitamins or supplements.
Try a different protein shake. Switch from whey concentrate to whey isolate for a lower lactose content, or try an egg or vegetarian protein powder. Vegan options include pea, hemp and rice. You may find that eliminating a shake with refined sugar, artificial sweetener or added vitamins solves the nausea problem.
Eat a banana 30 minutes before drinking your shake. Bananas promote mucus formation from the stomach lining to protect your stomach from acidic digestive juices that can cause nausea, according the University of Maryland Medical Center.
Try drinking smaller portions. Divide the protein shake into two or more servings. You may find your protein shake easier to digest if you consume it in small quantities. Sip the protein drink slowly to avoid swallowing air. Drinking too fast can contribute to nausea.
Take ginger to prevent nausea. If you've consulted your doctor and ruled out a medical condition, food allergy or food poisoning, taking ginger may help you consume protein shakes and control the nausea. Try ginger root tea or stirring a pinch of powdered ginger into a glass of water. Drink the ginger 20 minutes before drinking your protein shake.
