Staying hydrated during workouts is essential for peak performance, muscle function, and overall health. While water is the foundation, many fitness enthusiasts overlook the role of supplements in enhancing hydration. By strategically incorporating products like BCAA drinks, electrolyte powders, and bottled protein shakes, you can maintain fluid balance, reduce cramping, and sustain energy levels throughout your training session.
In this guide, we'll explore how to use supplements to stay hydrated during workouts, including the best timing, key ingredients to look for, and practical tips for integrating them into your routine. Whether you're hitting the gym, running outdoors, or doing high-intensity interval training, proper hydration can make or break your results.
Why Hydration Matters More Than You Think
Water makes up about 60% of your body weight and is critical for regulating temperature, lubricating joints, and transporting nutrients. During exercise, you lose fluids through sweat, and even a 2% loss in body weight from dehydration can impair performance, reduce strength, and increase fatigue. Supplements can help replenish not just water but also electrolytes and amino acids that aid recovery.
Many athletes mistakenly believe that plain water is enough, but intense or prolonged workouts deplete sodium, potassium, and magnesium. Adding a hydration-focused supplement can restore these minerals and keep your muscles firing optimally. For example, a BCAA drink provides branched-chain amino acids that support muscle repair while encouraging fluid intake.
- Aim to drink 500ml of water 2 hours before exercise, then sip during your workout.
- Use supplements with electrolytes if you sweat heavily or train in hot environments.
- Monitor urine colour as a simple hydration check: pale yellow means you're well-hydrated.
Key Supplements for Workout Hydration
Several supplement categories can boost hydration and performance. BCAA powders are a popular choice because they combine amino acids with flavoured water, making it easier to drink more. The added electrolytes in some BCAA blends help replace what you lose through sweat. Another option is bottled protein shakes, which provide fluid along with protein for muscle repair—ideal after a session when rehydration and recovery are both priorities.
Creatine monohydrate, while not a direct hydration supplement, draws water into muscle cells, improving cell volumization and hydration status. However, it's best taken consistently rather than just during workouts. For a quick energy and hydration boost, some athletes turn to thermogenic pre-workouts, but be cautious as caffeine can have a mild diuretic effect—pair them with extra water.
- BCAA drinks: sip throughout your workout for continuous hydration and muscle support.
- Bottled protein shakes: use post-workout to replenish fluids and start recovery.
- Electrolyte tablets or powders: add to water for intense or long-duration exercise.
How to Time Your Hydration Supplements
Timing is everything when it comes to hydration. Before your workout, drink water and consider a small serving of a BCAA drink to pre-load amino acids. During exercise, take regular sips—every 15-20 minutes—of a hydrating supplement. After training, a bottled protein shake like the White Chocolate Protein Shake can deliver fluid, protein, and carbs to kickstart recovery and rehydration.
Avoid chugging large amounts at once, which can cause bloating or stomach discomfort. Instead, spread your intake evenly. For morning workouts, you may need extra electrolytes to compensate for overnight dehydration. For evening sessions, a lighter BCAA drink can prevent overstimulation while keeping you hydrated.
- Pre-workout (30-60 min before): 300-500ml water with electrolytes or BCAA.
- During workout: 150-250ml every 15-20 minutes of a BCAA drink or water.
- Post-workout: 500ml of a protein shake or electrolyte beverage within 30 minutes.
Practical Tips for Staying Hydrated with Supplements
To make hydration a habit, keep a shaker bottle or reusable flask handy and pre-mix your BCAA or electrolyte drink before heading to the gym. Experiment with flavours like the Birthday Cake Protein Bar or a refreshing BCAA blend to make drinking more enjoyable. If you train in a hot climate or do endurance sports, consider adding a pinch of salt to your water or using a dedicated electrolyte supplement.

Track your sweat rate by weighing yourself before and after exercise—each kilogram lost equals roughly 1 litre of fluid to replace. Use supplements that taste good to encourage consistent sipping. Grenade offers a range of options from protein shakes to bars that can complement your hydration strategy, but remember: supplements are an addition to, not a replacement for, plain water.
- Flavour your water with BCAA powder to increase your intake naturally.
- Keep a hydration log to see how different supplements affect your performance.
- Combine a protein bar like the Fudged Up Protein Bar with a shake for a complete post-workout refuel.

Mastering workout hydration doesn't have to be complicated. By incorporating the right supplements—like BCAA drinks for sipping during exercise and bottled protein shakes for post-workout recovery—you can maintain fluid balance, improve performance, and recover faster. Start with a simple routine: pre-hydrate, sip consistently, and replenish after training. Explore Grenade's range of hydration-friendly supplements to find what works best for your body and goals.
