Coconut water has become a popular beverage choice recently and is often marketed as “mother nature’s sports drink”. It is derived from young green coconuts and is rich in potassium and low in fat and sugar. Compared to sports drinks - it is lower in sugar, sodium and calories and much higher in potassium. Potassium assists in alleviating muscle cramps that may result from exercise. Coconut water contains small amounts of sodium, calcium, magnesium and phosphorus.
Straight up Sparkling Coconut water from Raw C is a fantastic hydration option as it contains 100% pure coconut water (it is not produced from a concentrate) and is free from preservatives/cholesterol/fat/sugar/added sodium. It is rich in potassium, vitamins and minerals. It has a good pH balance. Natural Raw C is the freshest and most natural coconut water on the Australian market. This brand uses only the youngest coconuts (up to 7 months old) ensuring the highest natural nutritional benefits.
Excessive sweating results in the loss of especially sodium, potassium and chloride. Therefore, in addition to water, athletes need to also replenish electrolytes after a strenuous workout. All the major fluids of the body require large amounts of potassium to function, and 90% of the body's potassium lies within the cell walls. Thus, it is essential to replenish these electrolytes daily through the intake of clean fluids and foods.
When the kidneys are functioning correctly they regulate concentrations of electrolytes in conjunction with fluid levels in the body. During high intensity exercise or endurance sport much of the body's fluids (and electrolytes - especially potassium and sodium) are lost. Electrolytes are also lost during urination, vomiting, diarrhoea etc. Combining the intake of fluids with electrolytes results in more rapid rehydration as water follows electrolytes. Additionally, consuming electrolytes like sodium reduces the amount of water lost via urination, allowing the fluids to be more readily absorbed back into the muscles, tissue and nerves.
During strenuous exercise, endurance sport and extreme heat/humidity the body sweats excessively and loses both water and electrolytes. Staying adequately hydrated in these circumstances therefore requires replacement of both lost fluid and electrolytes. In these circumstances coconut water is a good choice.
The human body is composed mostly of water. The essential electrolytes most commonly found in the body are sodium, potassium, magnesium, bicarbonate, chloride, calcium, and phosphate. Electrolytes are minerals in the body that have an electric charge. They are found in blood, urine, tissues, sweat and other body fluids.
Electrolytes are obtained through your diet, but in cases where you need significant rehydration, beverages that contain water as well as electrolytes are key. In cases of severe dehydration medical treatment is required.
