Staying hydrated is essential for overall health and exercise performance. But despite the hype around sports hydration/drinks and electrolyte powders, the reality is that most people don’t need them.
If you’re wondering whether you really need an electrolyte drink after a workout, this blog will help you cut through the noise. As a dietitian, I’m here to break down the science of hydration, explain when electrolytes are actually helpful, and share some reputable Canadian brands to consider—only if you need them.
Hydration 101: Why It Matters
Proper hydration supports:
- Body temperature regulation
- Muscle and joint function
- Cognitive performance
- Energy and endurance
- Prevention of fatigue and dizziness
Even mild dehydration—just a 1–2% loss in body weight through sweat—can affect physical and mental performance. That’s why fluid intake matters, especially during longer or intense activity.
Water vs. Electrolytes: What's the Difference?
- Water replaces fluid lost through sweat and breathing.
- Electrolytes (such as sodium, potassium, magnesium) help the body maintain fluid balance, muscle contractions, and nerve function.
For the average workout (under an hour), water is typically enough. A well-balanced diet will replenish electrolytes naturally.
When Electrolytes Are Helpful
Electrolyte drinks or powders may be beneficial in certain situations:
- Prolonged exercise (more than 60–90 minutes), especially in heat or humidity
- Muscle cramping during or after workouts
- Recovery from illness involving vomiting or diarrhea
Food Sources of Electrolytes
Most people can get all the electrolytes they need from food:
- Sodium – table salt, broth, canned goods
- Potassium – bananas, potatoes, legumes, yogurt, leafy greens
- Magnesium – whole grains, nuts, seeds, legumes, dark chocolate
- Calcium – dairy products, fortified plant milks, tofu, leafy greens
A varied, balanced diet easily meets the needs of recreational and active individuals.
Canadian Electrolyte Brands - Sports Hydration Drinks
If your activity level or situation calls for additional electrolyte support, here are some brands widely available in Canada:
When choosing a product, look for those with 200–500 mg of sodium per serving, and minimal added sugars unless you're doing endurance activities.
Timing Your Fluids: Before, During, and After
- Before Exercise: Aim to start well-hydrated with a glass or two of water 1–2 hours before.
- During Exercise: Sip water regularly. If activity lasts more than an hour or you sweat heavily, consider an electrolyte beverage.
- After Exercise: Rehydrate with water and eat a balanced meal containing some sodium and carbohydrates.
Frequently Asked Questions: Sports Hydration
No. Water is sufficient for most people during short or moderate workouts.
Yes. Drinking too much water without replacing sodium can lead to hyponatremia, especially during prolonged endurance events. Drink according to thirst, and consider electrolytes if needed.
Powders and tablets let you control the concentration of electrolytes and sugar. Bottled drinks are convenient but often contain more sugar than necessary.
Generally, yes—when used appropriately, such as during prolonged sports tournaments or illness. For day-to-day hydration, water and meals are typically sufficient.
Final Thoughts
As a dietitian, I want to emphasize that for the general population, water and a well-balanced diet are enough to stay hydrated—even if you exercise regularly.
Electrolyte products have their place, but they’re not essential for most workouts. Focus on building good hydration habits, listening to your body, and using specialty products only when needed.
If you’re unsure about your hydration needs or whether an electrolyte product is right for you, consult a registered dietitian or health care provider for personalized guidance.
