PrintWhat’s the Best Way to Rehydrate Postworkout?

It’s well known that we need to rehydrate after exercise to replace sweat loss. But did you know that when you sweat you lose more than just water?

Electrolytes such as sodium and potassium are also lost in your sweat. These minerals need to be replaced when you rehydrate during and after exercise to restore the balance of water and electrolytes in your body (1).

Why Are Electrolytes Important?

Electrolytes are electrically charged minerals that travel through the blood and extracellular fluid (2). Sodium is the most highly concentrated electrolyte lost in sweat, and is needed by the body to help balance the level of fluids (1, 3). As a positively charged ion, sodium works in contrast with the negatively charged potassium to create cell membrane potential, which is essential for normal muscle and nerve function (4).

Maintaining stable sodium levels is especially important during an intense workout. Low sodium levels can result in a decrease in the amount of extracellular fluid in circulation, which results in less blood volume and a lowered blood pressure which can cause fatigue (5).

Potassium is another important electrolyte that helps to control the balance of fluids in the body. It also helps nerves and muscles “communicate” and supports heart muscles (3, 6). A lack of potassium in the body can cause muscle cramping and weakness, as well as leave you with low energy. Even though far less potassium is lost in sweat compared to salt, it’s still important to restore depleted stores after a workout (4).

Refuel on Carbs

It’s also essential to rehydrate with a drink that provides carbohydrate, as the body’s energy stores will have been depleted during your workout. More and more studies are suggesting that consuming carbohydrates during a workout can improve performance, endurance, and recovery (7, 8).

In addition, consuming carbs immediately after exercise works to your advantage. It’s the time when your muscles are ready to store glycogen at a much faster rate (9, 10). By consuming carbohydrate in the form of monosaccharides, or simple sugars, – as opposed to complex carbohydrate that will need to be broken down by the body – can increase the rate of delivery of the carbohydrate to be absorbed in the small intestine (11).

Introducing AMPED™ Hydrate

Sports drinks are a great tool to help rehydrate and restore electrolyte balance; however, many popular formulations tend to contain excess sugar and calories that can deter health-conscious exercisers from using these products.

With your goals in mind, Isagenix created AMPED Hydrate. This unique carbohydrate-electrolyte solution includes sodium and some potassium, and is also enriched with B vitamins and vitamin C. AMPED Hydrate also supplies the body with easily digestible carbohydrate that can be delivered to your muscles quickly. One of the benefits of consuming a carbohydrate-electrolyte mix is that sodium stimulates the uptake of sugar and water in the small intestine, which helps with rehydration (11).

No matter what exercise you’re undertaking, AMPED Hydrate helps to rehydrate, nourish, and energise your body to get the most out of every workout.
