PERFORMANCE HYDRATION
Stay hydrated every day with HYDRO Tablets, an easy, drop-in-water tablet that combines essential electrolytes and B vitamins to support energy, muscle function, and fluid balance, whether you’re training, recovering, or simply staying active.
4 KEY ELECTROLYTES
Each tablet contains sodium, calcium, magnesium, and potassium.
ON-THE-GO HYDRATION
Dissolves quickly in water for easy, convenient hydration wherever your day takes you.
SUPPORTS THE SWEAT
Replaces electrolytes lost through sweat to maintain your body’s fluid balance during exercise.
B1, B2, & B12 VITAMINS
Includes B1, B2, and B6(1,2) to support energy metabolism and protein utilization, helping your body convert food into fuel and recover efficiently.
- Vitamin B1 & B2 contribute to carbohydrate conversion.
- Vitamin B6 aids protein metabolism.
EVERYDAY HYDRATION
SiS HYDRO Tablets make it easy to stay balanced and energized throughout your day. Each serving provides a high-sodium formula to help replace electrolytes lost through sweat.
Compact and portable, they’re the simple, refreshing way to stay hydrated at work, on the trail, or during your workout.
WHY ELITE ATHLETES CHOOSE HYDRO TABLETS
- A refreshing, convenient, and low-calorie hydration.
- Clinically shown to hydrate better than water alone.
- 789mg of key electrolytes plus added B vitamins per serving.
- Helps regulate body temperature, prevent cramps, and maintain fluid balance.
SUGGESTED USE
Add 1 tablet to 16–17 oz (500ml) of water and let it fully dissolve. Consume within 24 hours once mixed.
Do not exceed 4 tablets per day.
DRIVEN BY SCIENCE
Even a 2–3% drop in body fluid can affect physical performance, focus, and recovery. During exercise, you lose fluids and electrolytes through sweat, so it’s critical to replace both to avoid dehydration. HYDRO Tablets are precisely formulated to deliver the right balance of electrolytes to keep you performing at your best in any condition.
DRINK BEFORE EXERCISE
Hydrating before you train sets the foundation for better performance. Experts recommend drinking 5–10ml of water per kilogram of body weight in the 2–4 hours leading up to activity (about 12–24 oz for a 155 lb athlete). Proper hydration helps regulate temperature, improve focus, and delay fatigue, especially in heat or humidity.
STAY HYDRATED
When you sweat, your body loses sodium, potassium, magnesium, chloride, and calcium: all vital for endurance and recovery. Sweat rates can range from 0.3–2.4 liters per hour, and failing to replace those losses can lead to fatigue, cramps, and reduced focus. Dehydration also increases body temperature and heart rate, making exercise feel harder. Starting hydrated—and staying hydrated—keeps your body performing smoothly from start to finish.
Each Hydro Tablet provides 789mg of essential electrolytes to replenish what’s lost through sweat and help restore hydration levels.
DAILY ELECTROLYTE NEEDS
Daily electrolyte needs vary by age, gender, and activity level. In general:
- Sodium: under 2,400mg per day
- Potassium: around 3,500mg per day
- Magnesium: 300mg for men, 270mg for women
- Calcium: 700mg per day
OPTIMAL ELECTROLYTE BALANCE FOR PERFORMANCE
Formulated to maintain hydration and muscle function, HYDRO Tablets deliver the ideal electrolyte ratio for daily activity and exercise. Keeping fluid losses below 2% of body weight helps maintain energy, endurance, and mental focus throughout your workout.
Each tablet includes Vitamin B1, B2, and B6 to support energy production and muscle repair. Together with electrolytes, they help your body convert carbohydrates and proteins into usable energy, so you can train harder, recover faster, and stay hydrated all day long.

Tastes great and keeps me hydrated on hot rides. I gave a few tablets for a friend to try and they have been his go-to electrolyte supplement since.

I put 5 stars because these are excellent for hydration when water is cold. I use these while I am at work, I live in a hot climate, and work out side a lot. The temp gets up in the 90's so you can dehydrate really fast. I put a tablet in a water bottle and keep the bottle in my cooler. The only thing I have negative to say is, it taste really, really bad when it is warm. I will not use it while training or racing on my bike, I have tried putting it the polar bottles, add ice, but still when it get a little warm its not good at all.

Great for hydration. Works best when allowed to sit in water bottle overnight so it dissolves thoroughly.

The Hydro Go Tablets are effective and convenient. They do not upset my stomach as some other have. They have become my go-to for long rides and long runs, as well as my pre-hydration regimen prior to long workouts and races. (As an aside, I take offense to your category of "Food, Beverage or Tobacco.")
