Electrolytes: When and How to Use Them for Pregnancy & Postpartum

Electrolytes are essential minerals that play a vital role in key body functions, especially during pregnancy and postpartum. The main electrolytes in the body include sodium, potassium, calcium, chloride, magnesium, and phosphate. 

During pregnancy, maintaining the right balance of electrolytes is crucial as they help regulate fluid balance, which is important for both the mother and the developing baby. Sodium, for instance, is critical for maintaining hydration and ensuring that cells absorb nutrients efficiently. This is particularly important as the mother's blood volume increases to support the growing fetus.

Electrolytes also support muscle function and chemical reactions in the body. They don’t directly impact energy but assist processes that control energy production, such as ATP synthesis, which is vital for coping with the increased energy demands during pregnancy.

Postpartum, electrolyte balance continues to be important as the body recovers from childbirth. Electrolytes are lost through sweat, urine, and more significantly during episodes of vomiting or diarrhea, which can be common during early pregnancy. Ensuring adequate electrolyte intake can help alleviate symptoms of dehydration like fatigue, headaches, or dizziness, which are often experienced during both pregnancy and postpartum.

When to Take Electrolytes:

• After exercising or being in a hot or humid environment.

• Following episodes of vomiting or diarrhea.

• If experiencing symptoms of dehydration such as dark-colored urine, dry skin, or headaches.

• When feeling fatigued or experiencing muscle cramps, which can be more frequent during pregnancy.

Whole foods like fruits and vegetables are excellent sources of electrolytes. However, during pregnancy and postpartum, additional supplementation may be needed in specific situations like those mentioned above.

Types of Electrolytes & Their Use During Pregnancy and Postpartum:

Sports Drinks (Ex: Gatorade, Powerade): Electrolytes (sodium in particular) have been used for decades to aid athlete’s hydration status. The problem with these sports drinks is that they often have a lot of sugar, moderate amounts of carbohydrates, and artificial food dyes. While sports drinks containing sugar do help your body absorb water, it is not the best fit for someone who is not engaging in intense exercise.

Coconut Water: I love that this is a natural food option for electrolyte replacement. This can be used to replace electrolytes, due to its content of essential minerals (potassium, calcium sodium, and magnesium). However, it contains high amounts of natural sugar so should be reserved for intense or high electrolyte replacement needs.

Himalayan Sea Salt + Lemon Juice + Water: This homemade concoction provides a small amount of electrolytes, which is good for enhancing daily hydration. This drink does contain electrolytes such as sodium, potassium, calcium, and magnesium. The exact quantities will vary on the amount of lemon and sea salt used. This is not the best option for more intense electrolyte replacement needs.

Powdered, low-sugar options:

• LMNT Electrolytes: Each Packet contains 1,000mg sodium, 200mg potassium, and 60mg magnesium. I love that there is no sugar in this brand. The science behind these electrolytes is also fascinating, check out that here. As you can see, this is the highest-containing sodium brand of electrolytes. I typically reserve this brand for intense electrolyte replacement needs. For moderate intense replacement needs you can use half a pack at a time.

• Redman’s Relyte Electrolytes: Each serving contains 810mg sodium, 400mg potassium, 60mg calcium, and 50mg magnesium. I love that there is no sugar in this brand (sweetened with stevia) and it is from natural Redmond Real Salt®, which contains naturally-occurring trace minerals. I also love that it contains higher levels of potassium from Coconut Water Powder.

• Ultima Electrolytes: Each serving contains 47mg calcium, 260mg potassium, 100mg magnesium, 90mg of chloride, 70mg of phosphorous, and 55mg of sodium. There is 0g of sugar. The sweetener is stevia. As you can compare the different brand, this offers the lowest amount of electrolytes per serving. This brand is best used for daily use of supporting hydration or mild exercise.

• Nuun Electrolytes: This brand offers a wide variety of electrolytes based on your needs.

  • Nuun Daily: Each tablet contains 30mg of calcium, 20mg of Magnesium, 75mg chloride, 200mg of sodium, and 125mg of potassium. Sweetened with stevia. As the name suggests, its best for daily hydration needs.

  • Nuun Sport: Each tablet contains 13mg of calcium, 25mg of magnesium, 40mg of chloride, 300mg of sodium, and 150mg of potassium. Sweetened with stevia. Again, as the name suggests it is best used for sports or after a mild to moderate intensity workout. Be sure there is no caffeine in this!

• Coconut Water: A natural option for replenishing electrolytes, rich in potassium, calcium, sodium, and magnesium. It is beneficial but should be consumed in moderation due to its natural sugar content.

Maintaining proper electrolyte levels is key to supporting both mother and baby during pregnancy and aiding recovery postpartum.
