The Benefits Of Intra Workout Supplements

Now that we've shown you the best intra workout supplements available in 2021, you're probably wondering what these products have to offer.

Well, there are many reasons why you should consider adding an intra workout supplement to your routine. In our opinion, they're one of the staple supplements every serious athlete should have in their stack.

Allow us to walk you through these products' main benefits and what to expect from taking one.

1. They Boost Energy And Power

Tired and fatigued during your intense workout, but want to continue pushing your body to the limit? Or are you merely looking to get the most out of your training sessions?

Then an intra workout with carbs is exactly what you need.

The fast-acting carbohydrates found in most of these products is the main reason they are so effective at rapid energy boosts. Your body absorbs them much faster than regular, simple carbs.

They'll fuel your entire workout, providing you with plenty of energy and power to break down as many muscle fibers as possible.

2. They Improve Recovery Rate

If you get yourself a properly formulated intra workout such as Formula XII, you'll find that they also can improve the rate at which you recover. Having your recovery rate improved can be a game-changer since it plays a massive role in the growth of new muscle tissue.

Certain promising ingredients, such as branched-chain amino acids, creatine, and betaine anhydrous, can significantly impact recovery.

Take creatine, for example. It's one of the most prevalent compounds when it comes to boosting recovery. It's even been clinically proven to improve recovery, muscle growth, and workout performance (1).

You're not just taking a supplement that helps you during the workout. An intra workout goes much further than that and enables you to improve recovery, which leads to more muscle growth. That's why we consider it to be such an essential product for those that are serious about changing and improving their physique.

3. They Keep You Hydrated

Making sure your body and muscles stay hydrated during a training session is essential. Intra workout supplements often contain a wide variety of electrolytes.

Electrolytes such as potassium, sodium, and magnesium are necessary for various processes in the body. Those processes include muscle function and contraction, which you obviously want to have optimized as much as possible.

When you work out intensively, your water goes out of the body because your sweating; this is when you go through your electrolytes (2). So, those electrolytes must get replenished with the help of an intra workout supplement.

By ensuring you're getting in enough electrolytes, you will stay hydrated through the entire workout, which helps your overall performance.

If you're interested in combining an intra workout with other products that can help you boost performance, read our best pre-workout supplements and best bcaa supplements articles.

Should Intra Workouts Contain Carbs?

When you look at the supplement facts of different intra workout supplements, you'll find that many contain carbohydrates. It's typically between 10 to 30 grams per scoop, depending on what the source is.

Carbs, short for carbohydrates, are essential in an intra workout supplement. You're going to want to get a product that contains easily digestible carbohydrates, such as Clusterdextrin or Modcarb.

Having a source like the ones mentioned is extremely important for intense workouts. This is because your body and muscles will be able to use those fast-acting carbs as a source of energy during a workout.

Let's take Formula XII by Huge Nutrition as an example. It contains three sources of carbohydrates, one of which is Clusterdextrin (Highly branched cyclic dextrin). 

Clusterdextrin is an excellent ingredient and great example because it has favorable properties that allow your body to digest it much, much faster than regular carbohydrates. Even research has shown it to boost exercise performance (1).

Personally, I feel that these high-quality carb sources do wonders during an intense workout session. It's like your body and muscles instantly absorb them and proceed to turn them into energy. I'm always able to push myself beyond my limits when I'm using one of these products.

So if you're looking for an intra workout supplement that can help you boost your performance, get one that contains quality carbs.

The Bottom Line

We've shown you what we consider to be the best intra workouts of 2021 based on ingredients, user reviews, and our own experiences.

These products are, by far, the most advanced products to maximize performance during your workouts.

Not only do they provide a direct source of energy and hydration, but some can also help improve recovery and muscle mass.

Take a look at one of the products from our top 10; we recommend going with Huge Nutrition's Formula XII due to the wide variety of scientifically proven ingredients.
