Best Drinks for Energy During Pregnancy

DetoxWater Editorial Team•Published November 5, 2026

Partly: during pregnancy, water can help with energy if dehydration contributes to tiredness, while drinks containing carbohydrates or protein provide calories the body can use. No drink reliably fixes every cause of fatigue, so the safest choice depends on what you can tolerate and whether you have a medical condition.

For a broader comparison beyond pregnancy, see the best drinks for energy. During pregnancy, pay particular attention to caffeine, food safety and any advice from your maternity care team.

What are the best drinks for energy during pregnancy?

Water is a good first choice throughout the day. If you also need food, pasteurized milk, a fortified soy drink or a smoothie can provide calories as well as fluid. Coffee or tea can temporarily improve alertness, but caffeine needs to be limited during pregnancy.

Water

Water helps prevent dehydration, which can contribute to tiredness. It does not supply calories, so it will not replace a meal or correct fatigue caused by a problem such as anemia.

Keep water available and drink regularly rather than waiting until you feel very thirsty. If nausea makes a full glass difficult, try small, frequent sips or water at a temperature that is easier to tolerate.

Pasteurized milk

Pasteurized milk provides fluid, protein and carbohydrates, as well as nutrients such as calcium. It can be a useful choice alongside breakfast or a snack when you have gone a while without eating.

Choose pasteurized rather than raw milk during pregnancy. If milk causes digestive discomfort or you cannot tolerate it, ask your clinician or a dietitian about alternatives that fit your needs.

Fortified soy drink

A fortified soy drink can be an option if you avoid dairy. Soy drinks generally provide protein, and fortified versions may also contain calcium and vitamin D; check the label because products differ.

Choose an unsweetened version if you prefer to limit added sugar. Other plant drinks may contain much less protein, so do not assume every product is nutritionally equivalent to milk or a soy drink.

A smoothie made with safe ingredients

A smoothie made with washed fruit and pasteurized milk or a fortified soy drink can provide fluid and calories. Including a protein-containing ingredient can make it more substantial than fruit and water alone.

Wash produce under running water, use pasteurized dairy or juice, and refrigerate the smoothie promptly. If you have gestational diabetes or another condition that affects blood glucose, ask your care team how a smoothie can fit your eating plan.

Coffee or tea within the caffeine limit

Caffeine can temporarily increase alertness, so a modest serving of coffee or tea may be useful if you choose to consume caffeine. It does not replace sleep, food or treatment for a medical cause of fatigue.

The caffeine content varies by drink and serving size. Check the label when possible, count caffeine from other sources, and avoid it if your clinician has advised you to do so or if it worsens symptoms such as difficulty sleeping.

Why might these drinks be safe or unsafe during pregnancy?

The potential benefit depends on the reason you feel tired. Water may help if you are dehydrated; milk, a soy drink or a smoothie can supply calories when you need food. Neither approach is a dependable treatment for fatigue caused by anemia, thyroid problems, infection, depression or another medical condition.

There is no pregnancy-specific clinical evidence cited here that ranks drinks by how well they relieve fatigue. A drink that feels helpful to one person may make little difference to another, especially when tiredness has several causes. Regular meals and rest matter too.

Food safety is important even when a drink seems nutritious. Raw milk and unpasteurized juice can carry harmful germs, so choose pasteurized products. Wash fruit and other produce before adding them to a drink, and keep perishable drinks refrigerated.

Caffeinated energy drinks are a less predictable choice during pregnancy. They may contain substantial caffeine or added stimulants and herbal ingredients whose safety in pregnancy is uncertain. Avoid them rather than relying on them for energy; if you have already had one, check its label and ask your clinician about any concerns.

Herbal drinks are not automatically safe just because they are caffeine-free. Ingredients and concentrations vary, and some have not been adequately studied in pregnancy. Check with your maternity care team before regularly using an herbal product or supplement for energy.

How much is safe to drink during pregnancy?

The American College of Obstetricians and Gynecologists recommends drinking 8 to 12 cups of water a day, approximately 1.9 to 2.8 liters, during pregnancy. Your needs can vary, and other beverages also provide fluid. If your clinician has given you a different fluid target, follow that advice.

For caffeine, the same organization recommends less than 200 milligrams per day during pregnancy. Count caffeine from all sources, including coffee, tea, chocolate, soda, energy drinks and supplements. Decaffeinated products can still contain some caffeine.

There is no single safe number of cups of coffee or tea that applies to every product: caffeine content varies with the drink, preparation and serving size. Check the amount when it is available, and choose caffeine-free options if you cannot tell how much caffeine you are consuming. You do not need caffeine for a healthy pregnancy.

Milk, fortified soy drinks and smoothies do not have a single pregnancy-specific amount for improving energy. Use them as part of your usual meals or snacks rather than expecting a particular quantity to resolve fatigue. If a drink replaces food regularly because eating is difficult, tell your maternity care team.

If nausea or vomiting makes drinking hard, try small sips more often rather than forcing a large amount at once. Contact your care team promptly if you cannot keep fluids down, feel dizzy or are passing little urine; you may need assessment and treatment rather than a different beverage.

When should you talk to your doctor about low energy during pregnancy?

Bring up fatigue at a prenatal visit if it persists, is getting worse or interferes with daily activities. Your clinician can consider possible causes and decide whether you need an assessment or tests. Do not start an energy supplement or change prescribed medication on your own.

Ask for individual advice if you have anemia, thyroid disease, diabetes, kidney disease or a condition that requires a fluid restriction. Mention any medications and supplements you take, including caffeine-containing products. Your care team can help you choose drinks that fit your treatment and nutritional needs.

Contact your maternity care team promptly if vomiting prevents you from keeping fluids down or you have signs of dehydration, such as very little urine or dizziness. Also contact them if you notice reduced fetal movement when you are accustomed to feeling movement.

Seek urgent medical care for chest pain, severe shortness of breath, fainting, heavy vaginal bleeding or severe abdominal pain. A severe headache or vision changes also need urgent assessment during pregnancy. Do not wait to see whether a drink improves these symptoms.

Frequently asked questions

Is decaf coffee completely caffeine-free?
