The Do’s and Don’ts of Mass Gain Supplements, According to Science


You can’t just consume carbohydrates from a single source. If you did that, your body won’t be able to metabolize the necessary amount of carbohydrates to meet its daily needs. Because of this, more and more mass gainers in the market included mixed carbohydrates as one of its ingredients to try and keep up with the demands of the market.

By using different types of carbohydrates that are metabolized using a different transporter, smart gainers using mixed carbohydrates make it possible to meet your daily carbohydrate needs more efficiently.

Among the most common types of carbohydrate sources used are glucose, sucrose, fructose, and maltodextrin.

The use of mixed carbohydrates is one of the key reasons why you may want to ditch your old mass gainer and find something newer that actually uses multiple sources.


The human body relies on amino acids to help make its protein to help the body break down the food that we eat. Although there are many different types of amino acids (as many as 20), only 9 are referred to as essential. The worst part is that our bodies do not naturally produce these said amino acids, which is exactly why we have to rely on supplements.

These amino acids include leucine, isoleucine, methionine, lysine, threonine, phenylalanine, tryptophan, valine, and finally, histidine.

Each of these amino acids plays their own role in the human body. Some help reduces post-workout muscle damage and improves recovery, while others help minimize the amount of amino acids burned during your workout session. But, all in all, these amino acids work in conjunction with each other to make the muscle-building process as efficient as possible.

Of these nine essential amino acids, however, one stands out the most. Leucine is an amino acid that studies have shown help kick-start the biological process necessary for building muscles.

Make sure to pay close attention to the leucine content of your mass gainer. It’s not unusual for some products to try and skimp on leucine to make their products cheaper.

Ideally, a smart gainer should have a minimum of three grams of leucine and contain additional essential amino acids, as well as extra BCAAs.
