Gatorade can help with POTS, but it’s far from ideal. It contains some sodium, which is the key electrolyte people with POTS need, but not nearly enough to make a meaningful dent in the 3,000 to 4,800 milligrams of daily sodium most POTS treatment plans call for. A 20-ounce bottle of original Gatorade delivers just 270 milligrams of sodium. You’d need to drink more than 14 bottles a day to reach the lower end of clinical sodium targets, and all that sugar would likely make your symptoms worse.
Why Sodium Matters for POTS
POTS causes your heart rate to spike when you stand up, largely because your body has trouble keeping enough blood circulating to your brain and upper body. One of the most common treatments is increasing sodium intake, because sodium pulls water into your bloodstream and expands your total blood volume. More blood volume means your cardiovascular system doesn’t have to work as hard when gravity shifts blood toward your legs.
The Heart Rhythm Society’s expert consensus recommends 10,000 to 12,000 milligrams of salt per day for POTS patients, which translates to roughly 4,000 to 4,800 milligrams of sodium. The American Society of Hypertension suggests a slightly wider range of 2,400 to 4,000 milligrams of sodium daily. For context, the average American consumes about 3,400 milligrams of sodium per day, so most people with POTS need to actively add sodium on top of what they already eat. Clinicians typically recommend adding 1,000 to 2,000 milligrams of supplemental sodium three times a day, paired with 2 to 3 liters of fluid.
How Gatorade’s Sodium Stacks Up
Original Gatorade Thirst Quencher contains 160 milligrams of sodium per 12-ounce serving (about 270 milligrams in a standard 20-ounce bottle) and 45 milligrams of potassium per 12 ounces. Compare that to a medical-grade oral rehydration solution, which packs roughly three times the sodium concentration. In lab terms, Gatorade sits at about 18 millimoles of sodium per liter, while oral rehydration solutions deliver around 61 millimoles per liter.
That gap matters. If you’re relying on Gatorade as your primary electrolyte source, you’re getting a fraction of what your body needs to meaningfully expand blood volume. It’s better than plain water, which dilutes your blood without adding electrolytes, but it falls well short of what POTS management actually requires.
The Sugar Problem
The bigger concern with original Gatorade is its sugar content: 21 grams of carbohydrates per 12-ounce serving. For someone with POTS, sugar isn’t just empty calories. It can actively worsen symptoms.
Research published in the Journal of the American Heart Association found that after consuming glucose, people with POTS experienced a 21% increase in heart rate while standing, compared to just 6% in healthy controls. At the same time, their stroke volume (the amount of blood the heart pumps per beat) dropped by about 10%. This happens because sugar triggers the release of a gut hormone that dilates blood vessels in the abdomen, pulling even more blood away from your brain and heart. Essentially, a sugary drink can trigger the exact hemodynamic shift that POTS patients are trying to prevent.
Dysautonomia International’s treatment guidelines specifically advise people with POTS to avoid sugary drinks while staying well hydrated. Meals and beverages rich in carbohydrates are listed among the factors that exacerbate POTS symptoms.
Gatorade Zero: A Better Option
Gatorade Zero eliminates the sugar issue entirely, with zero grams of carbohydrates and zero calories, while providing the same 160 milligrams of sodium and 45 milligrams of potassium per 12-ounce serving. If you’re choosing between original Gatorade and Gatorade Zero, the zero-sugar version is the clear winner for POTS.
That said, the sodium content is still low. You’d need to drink roughly 25 twelve-ounce servings of Gatorade Zero to reach 4,000 milligrams of sodium, which is nearly 2.5 gallons. That’s neither practical nor comfortable. Gatorade Zero works best as one piece of a broader hydration strategy, not the whole plan.
What Works Better
Several alternatives deliver significantly more sodium per serving. Products specifically designed for electrolyte loading (brands like Normalyte, Liquid IV, Trioral, and LMNT) typically contain 500 to 1,000 milligrams of sodium per packet. Medical oral rehydration solutions available at pharmacies also provide higher sodium concentrations. Some people with POTS use salt tablets or simply add a measured amount of table salt to water, which is cheap and precise.
The most effective approach combines multiple sodium sources throughout the day. Salty foods at meals, an electrolyte drink between meals, and salt tablets or packets when you need a quick boost all work together. Spreading your sodium intake across the day, rather than loading it all at once, helps maintain a more stable blood volume. Fluid intake should total 2 to 3 liters daily, with most experts recommending a mix of water, electrolyte beverages, milk, tea, smoothies, and soups.
One important finding from exercise research: when people drink fluids during physical activity in hot conditions, the total volume of fluid consumed matters more than the exact sodium concentration of the drink. Both sports drinks and oral rehydration solutions maintained blood volume equally well during exercise. This suggests that for short-term hydration during activity, simply drinking enough of any electrolyte-containing fluid helps. For the longer-term goal of expanding baseline blood volume in POTS, though, hitting your daily sodium target is what matters most, and that requires higher-sodium sources than Gatorade alone can provide.
The Bottom Line on Gatorade and POTS
Gatorade isn’t harmful for POTS, and Gatorade Zero in particular is a reasonable way to stay hydrated without the blood sugar spikes that worsen symptoms. But treating it as a primary electrolyte solution leaves you far short of the sodium levels that actually improve POTS symptoms. Think of it as a supplement to your hydration plan, not the foundation. Pair it with higher-sodium options and salty foods to get closer to the 3,000 to 4,800 milligrams of daily sodium that clinical guidelines recommend.
