Electrolyte deficiency is a common problem among athletes. Typical signs and symptoms of electrolyte imbalance are muscle cramps, fatigue, nausea, headaches, constipation or diarrhea. In extreme cases this may lead to heart irregularities or cardiac arrest. These problems can be alleviated through proper nutrition and by replenishing effective sources of electrolytes following exercise sessions. When it comes to the best drinks for remineralizing one’s body water after physical activity, there are really only three options: coconut water with sugars and salts; full-strength sports beverages such as Powerade and Gatorade; and diluted fruit juice with sugar added (but that’s not enough).
