Informational guide to Cluster Dextrin/Dextrose Supplements

What Is Cluster Dextrin/Dextrose?

Dextrin is a group of carbohydrates with a low molecular weight. Often, they’re produced in the body during digestion through enzymes. Dextrin will come in the form of a white, brown or yellow powder, which is water soluble.

It’s fairly common to supplement dextrin into the diet through the use of cluster dextrin/dextrose. Cluster dextrin is similar to natural dextrin but is manufactured through the application of a branching enzyme onto cornstarch. It’s been on the market since 2002, and can often be found in sports drinks.

What Does Cluster Dextrin Do?

Are you aware that, after working out, your body loses a lot of blood sugar? This is because carbohydrates, mainly glycogen, are used by your muscles as their main source of energy when you exercise.

Even after exercising for just 30 minutes, your body’s carbohydrate resources must be replenished in order to avoid hypoglycemia. What’s more, low glycogen levels in the body will not only affect your strength but also your ability to make any gains in the gym.

This is where cluster dextrin/dextrose comes in, as it’s important to consume a decent amount of carbs two hours after training. Simply consume a cluster dextrin supplement intra-workout or post-workout for the best results.

The Benefits of a Cluster Dextrin

So, what exactly do these cluster dextrin products achieve?

What to Look for in the Best Cluster Dextrin

So, how do we know what to look for in the best supplements for the job? Let’s see…

Sugar Levels

Before working out, your blood sugar levels should be between 100 and 250 mg/dL. If you feel shaky, weak or confused during your workout, your blood sugar levels may be too low, and a boost of around 15 grams of sugar should help. Any products with this amount, or a little more, are ideal for a post-workout supplement to replenish your blood sugar levels.

Includes BCAAs

BCAAs, or branched-chain amino acids, are often found in gym supplements. They include the amino acids leucine, isoleucine and valine, usually in a 2:1:1 formula for the best results, and are known for their aid in muscle recovery. They’re usually found in the food you eat, but sometimes this isn’t enough if you work out regularly.

Proteins are essential in the recovery and growth of your muscles. When BCAAs enter your body, they break apart and piece together again, forming new chains of amino acids to create the proteins needed to aid this recovery. This helps to not only build muscle but also reduce muscle soreness.

Some of the supplements we’ve featured do include BCAAs.


Although many of these cluster dextrin products impress us with their unique ingredients, we have to choose a favorite. We love the Now Sports Dextrose Powder most of all, for a number of reasons.

Firstly, you get good value for money with this product, as there are 227 servings per container. This is almost five times higher than our next highest product, servings-wise.

Otherwise, we love the Now Foods’ ethos in terms of helping everyone achieve their gains. Its fantastic clinical trials on humans mean the products are trustworthy, safe and actually work!
