What Happens to Your Hydration When You Drink Zero Sugar Sprite

One TikTok claim circulating now suggests that drinking Sprite Zero instead of water before bed hydrates you better, and it doesn’t wake you up to pee.

However, health experts say the switch won’t make much of a difference, and water is still your best bet.

Why Sprite Zero Isn’t More Hydrating Than Water

Hydration comes down to fluid intake, electrolyte balance, and how your body absorbs and retains liquid. Water does this exceptionally well, which is why it’s the gold standard.

The idea behind the Sprite Zero hack is that it contains electrolytes and stays in your body longer than water does. The small amount of sodium in Sprite Zero might help your body absorb and retain fluids, particularly when you’re mildly dehydrated, according to Kezia Joy, RDN, a registered dietitian nutritionist and medical advisor at Welzo.

Still, the small amount of sodium may not make a difference. “The potassium citrate and sodium citrate in Sprite Zero are for flavoring, not electrolytes,” said Magen Luhn, MD, a board-certified family medicine doctor at Houston Methodist Willowbrook Hospital.

“Any electrolytes touted by the trend are coming from other supplements people are adding to the Sprite Zero,” Luhn said.

Most people don’t need to worry about electrolytes overnight, Luhn added. Electrolyte losses during sleep are minimal, and most adults get more than enough sodium and potassium through food during the day.

Joy said that unless you’ve been sweating heavily, exercising intensely, or dealing with illness, plain water is generally sufficient before bed.

Why Some People Might Wake Up Less to Pee

The viral appeal centers on one promise: waking up less to pee. Some TikTok users attribute this to Sprite Zero’s “electrolytes,” but that might not be why.

Luhn noted that the trend may work indirectly. “People might be drinking this Sprite Zero mix instead of consuming drinks that can increase urination (such as tea or coffee) or that are known bladder irritants, such as alcohol,” she said. “This would decrease their nightly urination.”

In addition, “the added electrolyte mixes people are adding could possibly alkalinize the urine,” she said. This may reduce bladder irritation and the urge to urinate, though it doesn’t reduce urine production itself.

Drawbacks to Consider

According to Luhn, Sprite Zero itself isn’t inherently problematic before bed since it contains no caffeine or added sugar.

However, drinking it before bed comes with a few potential downsides to keep in mind:

• Bloating and discomfort: Carbonation can cause gas and bloating, which may be uncomfortable when lying down.
• Acid reflux risk: The acidity of soda can trigger reflux or heartburn, especially at night.
• Dental concerns: Acids can contribute to enamel erosion, even without sugar.
• Sleep sensitivity: While Sprite Zero contains no caffeine, some people are sensitive to artificial sweeteners, which may affect digestion or sleep quality.
• False sense of hydration: Feeling hydrated doesn’t always mean you’re meeting your body’s actual fluid needs.
