Should You Choose Whey Protein or Mass Gainer?

The supplement industry has exploded with a variety of supplements today. Owing to a lot of hype and confusion swirling around the supplement industry, it’s tough to figure out what to choose from among the dizzying assortment of dietary and nutritional supplements.

For your information, the best way to choose a supplement is simply to understand the supplement. When you know and understand the essentials of each supplement, half the job is done. This is exactly what applies to the choice between Whey Protein and Mass Gainer.

Let’s go ahead and understand which supplement you should go for based on your requirement.

Whey Protein

Whey, as you know, is a dietary supplement, a by-product of the cheese manufacturing process. The purest, highly bioavailable protein is known for its rapid digestion. This muscle fuel helps amp up daily protein intake. It not only benefits athletes and bodybuilders but is suitable for everyone who wants to stay fit and healthy.

Whey is classified as Whey Protein Isolate/Whey Protein Concentrate and Whey Protein Blend based on the protein content.

Mass Gainer

Mass Gainer/Weight Gainer is a supplement that features protein along with a high quality of carbohydrate and fat to boost your calorie intake. Mass Gainer usually contains carbohydrates and protein is a ratio 3:1, meaning each serving of mass gainer provides 90 grams of carbohydrates and 30 grams protein. 

Difference between Whey Protein & Mass Gainer

Before we talk about the difference between Whey Protein and Mass Gainer, let’s first understand the similarity between the two. Both Whey and Mass Gainer contain protein, which means both of them to assist in muscle recovery and muscle growth.

The major difference between the 2 lies in the number of calories and the amount of protein obtained from each.

  • Typical Whey gives calories around 100-150 calories/serving while a serving of Mass Gainer provides a whopping 1250-1500 calories.

  • Normally, a Mass Gainer supplies 22 to 35% protein whereas Whey Protein supplies more than 60% protein.

  • Mass Gainer is rich in carbohydrates and fats, but Whey Protein has very little of both.

Both Whey Protein & Mass Gainer Are Designed For Different Purposes and Choosing the Supplement Is Based On Your Goal

  •  Want To Build Muscle?

If you are a hard trainer who’s finding it difficult to gain weight easily and want to build a significant amount of muscle mass, you must choose a mass gainer.

If you are expecting slow gains with controlled body fat percentage, a Whey Protein could probably be the supplement you need.

  •   Want To Lose Fat?

If you have already built enough muscle mass and want to cut fat, while preserving the muscle mass, it’s definitely not a simple job.

In this case, you need to for Whey Protein, because Whey prevents muscle catabolism while helping to gain satiety.

  • Want Lean Body?

If all you dream for is to have a lean physique, then Mass Gainer shouldn’t be your choice, because Mass Gainer will ruin the chances of achieving a lean body by making you bulk.

Choose Whey Protein Isolate as it has negligible carbohydrates and fats which help you develop the aesthetic look.

  •  Want To Gain Weight/Bulk?

Do you still remain skinny no matter how much food you eat? If that’s your concern, Whey Protein is not the one you are going to benefit from, as Whey can’t help you get big and strong.  Mass Gainer is the one you must go for. A Mass Gainer contains carbohydrates that spike your insulin, this leads to fat storage. Moreover, you just can’t get enough calories in a day from the food you eat. By providing high calories, a Mass Gainer helps you get bigger and stronger.

  •  Want To Improve Sports Performance?

Sportspeople must always be cautious about their weight as it might affect their performance. Mass Gainer is not a viable option for them. Instead, sportspeople must go for Whey Protein, which is particularly rich in BCAA to support endurance, stamina and improve performance.

Mass Gainer helps you gain weight and bulk quicker than Whey Protein. Mass Gainers are not preferred to be taken without the workout. It is also not advisable for people who easily gain weight. If you don’t work out, a Mass Gainer will just add fat and no muscle.

Whey Protein is suitable for both bulking and cutting stages and its supplementation is regardless of your workout regime.

In the end, whether Whey Protein or Mass Gainer, it doesn’t work if you expect the fastest results without putting in the hard work and dedication required.
