The core issue with sports drinks when sick
When you are sick, especially with symptoms like fever, vomiting, or diarrhea, staying hydrated is crucial for a speedy recovery. Your body loses significant fluids and electrolytes, which are minerals essential for nerve and muscle function, and for balancing fluid levels. It’s a common belief that sports drinks like Gatorade and Powerade are the best way to replenish these losses, but this is often a misconception, particularly due to their high sugar content.
For exercise-induced dehydration, the sugar in sports drinks provides quick energy for muscles. However, this same high sugar content can be problematic when you're sick. During a stomach illness, excessive sugar can pull water into the gastrointestinal tract, which may exacerbate diarrhea and worsen dehydration. While both Powerade and Gatorade contain electrolytes like sodium and potassium, the balance of these minerals is designed for athletes, not for illness-related dehydration. Clinical solutions, such as oral rehydration solutions (ORS) like Pedialyte, are formulated with a more precise balance of salts and glucose to optimize absorption and combat dehydration more effectively.
A comparative look at Powerade and Gatorade
While neither is the top recommendation for illness, a closer look at their nutritional makeup reveals slight differences. Both drinks have similar base ingredients but differ in their specific sugar sources and added vitamins.
| Feature | Powerade (e.g., 20 oz bottle) | Gatorade (e.g., 20 oz bottle) |
|---|---|---|
| Sweetener | High-fructose corn syrup | Dextrose |
| Sodium | Around 150 mg per 12 oz | Around 160 mg per 12 oz |
| Potassium | Around 35 mg per 12 oz | Around 45 mg per 12 oz |
| Added Vitamins | B3, B6, B12, Magnesium | None |
| Electrolyte Balance | Slightly higher potassium | Slightly higher sodium |
For someone who is simply looking for a preference-based choice, the differences in electrolyte balance between Powerade and Gatorade are minor. Powerade offers additional B vitamins, but these have no significant impact on hydration effectiveness for illness. The core issue remains their sugar content, which is high in both. However, both brands now offer lower-sugar or sugar-free options (e.g., Gatorade Zero, Powerade Zero) which are much better choices if you still prefer a sports drink taste.
Better alternatives for illness-related dehydration
If you are feeling unwell and losing fluids, it is best to opt for drinks that prioritize hydration and are gentle on the stomach. Fortunately, there are several options that are more effective and healthier than traditional sports drinks.
- Oral Rehydration Solutions (ORS): Medically formulated solutions like Pedialyte are the most effective for replacing fluids and electrolytes lost from vomiting and diarrhea. They contain an optimal balance of electrolytes and sugar for maximum absorption.
- Clear Broths and Soups: Warm chicken or vegetable broth is excellent for hydration and replenishing sodium, and it's soothing for a sore throat.
- Coconut Water: A natural source of electrolytes, particularly potassium, with less sugar than typical sports drinks.
- Diluted Juice: If you need a bit of flavor and sugar, dilute 100% fruit juice heavily with water to minimize the sugar intake.
- Herbal Tea: Non-caffeinated herbal teas can be comforting and help with fluid intake. Add a little honey and lemon for extra soothing power.
Practical tips for staying hydrated when sick
Beyond choosing the right beverage, how you approach hydration can significantly impact your recovery. Here are some practical tips to follow:
- Sip, Don't Chug: Drinking large amounts at once can overwhelm your system, especially if you have nausea. Instead, take small, frequent sips throughout the day.
- Consider Ice Chips or Popsicles: If you're struggling to keep liquids down, freezing your oral rehydration solution or diluted juice into ice chips or popsicles is an effective way to stay hydrated.
- Listen to Your Body: Pay attention to signs of dehydration, such as dark urine, dry mouth, or fatigue. Your body will signal when it needs more fluids.
- Avoid Problematic Beverages: Steer clear of caffeinated drinks, alcohol, and sugary sodas, as they can further dehydrate you and irritate your stomach.
The takeaway: Prioritize clinical solutions over sports drinks
For illness-related dehydration, the answer to Is Powerade or Gatorade better when sick? is that neither is ideal. While both contain electrolytes, their high sugar content can be counterproductive, potentially worsening symptoms like diarrhea. When battling a cold, flu, or stomach bug, prioritize plain water, oral rehydration solutions (ORS), broths, or diluted juices to replenish fluids and electrolytes safely and effectively. For mild dehydration without digestive issues, diluted sports drinks or zero-sugar versions may be acceptable, but ORS remains the gold standard for restoring balance during illness.

Conclusion: Make an informed choice for your health
When illness strikes, your focus should be on gentle, effective recovery. Opting for a beverage specifically designed for rehydration during sickness, like an oral rehydration solution, is your best bet. By understanding the key differences between sports drinks and clinical-grade options, you can make an informed decision that supports your body's healing process and gets you back on your feet faster.
