Best Electrolyte Tablets for Runners – Take Those Endurance Levels Up

You need more than water to rehydrate if you are a heavy sweater.

Athletes like runners who pour sweat need electrolytes to nourish their bodies and regain strength and energy. When you can’t eat food filled with electrolytes during an intense workout, it might be time to turn to electrolyte tablets.

We’ll go through the best electrolyte tablets for runners and the different ways you can fix an electrolyte imbalance in your body.

Whether a marathon runner or a sprinter, this article will help you keep electrolyte levels high even after plenty of sweating.

What are Electrolytes?

When you sweat, you lose more than water. Over 99% of sweat is water, but 1% is salt and fat.

If you are a heavy sweater, it all makes sense now why any sweat that gets in your mouth tastes salty. Ew, right? When we rehydrate, we must replace the water and the extinguished salt.

So what are electrolytes exactly? They are a combination of minerals in your body dissolved in water to produce the energy you need throughout the day.

When we sweat, those electrolytes in the water leave the body. When you lose electrolytes, you must replenish them for your body to function correctly. The main minerals that make-up electrolytes are calcium, potassium, and sodium chloride.

Without those essential minerals, your body cannot regulate the amount of fluid in your bloodstream. That can lead to muscle cramps or blood clots. By replenishing lost electrolytes, we help the body function properly again.

What are Electrolyte Tablets?

How do we go about replenishing electrolytes? We’re glad you asked.

A fast way is to drink a sports drink filled with electrolytes or dissolve electrolyte tablets or powder in water. An electrolyte tablet can mean a better performance after heavy sweating.

Studies have shown that people who supplement with electrolyte tablets had a significant improvement in endurance and better heart rate performance.

You have to love science!

Defeating an Electrolyte Imbalance

An electrolyte imbalance is when the level of electrolytes in your blood is too high or too low.

When that happens, your body feels tired and lethargic. Side effects range from nausea and vomiting to muscle cramps and blood clots. Sounds pretty awful, right?

Knowing what causes this helps you to prevent it from happening. We talked about excessive sweating, but poor nutrition, not drinking enough water during vigorous exercise, and prolonged exercise are all factors.

The excellent news is that electrolyte drinks and tablets are there to ensure you don’t have an imbalance. It’s all about keeping things in the normal range and staying hydrated, especially for those endurance athletes.

When to Grab that Sports Drink?

So when should you replenish those electrolytes? You need to replenish after an intense workout, but you can also do it before and during a strenuous exercise that lasts for an hour or more.

If it’s sweltering outside, it’s a good idea to grab an electrolyte drink as you might be sweating just standing outside. It’s better to hydrate before dehydrating because it’s an uphill battle. Replenishing electrolytes when you are sick is also essential.

It will help your body fight whatever virus or ailment you have.
