5 Best Hydration Tablets

Best Hydration Tablets

Whether you’re exercising, training, traveling or just having fun in the heat, staying hydrated is the most important thing to keep in mind. We'll dive into the five best hydration tablets you can take to maximize your fluids.

What Causes Dehydration?

Dehydration is a condition that occurs when you lose more fluids than you take in. When you're dehydrated, your body doesn't have enough water and other fluids to carry out its normal functions.

The most common causes of dehydration are:

  • not drinking enough water
  • competitive training or athletic competitions
  • during exercise, sports or workouts
  • excessive sweating
  • high heat conditions or heatstroke
  • vomiting or diarrhea
  • medications such as antihistamines, diuretics, and antidepressants
  • fever or sickness

Water makes up about 60 percent of your body weight. If you become dehydrated, your blood volume can decrease and blood pressure drops. This leads to your organs not getting enough oxygen and nutrients. This process could potentially cause an imbalance in electrolytes like sodium and potassium, which are important for regulating nerve impulses and muscle contractions throughout the body.

If you’re an active person and not getting enough water, it can have a negative impact on your mood, energy level, and physical performance. Symptoms of dehydration include, dry mouth or thirst, dark yellow urine, fatigue or tiredness, decreased urine output, low blood pressure, headaches, dizziness or lightheadedness, and in extreme cases loss of consciousness. 

Hydration tablets, chewable hydration tablets, and cellular hydration supplements are a great way to combat dehydration.
