But, in some cases, it may prove bad for your kidneys. So, we will know that in detail.

First of all, you should never use mass gainer. It is high in calories that you can easily take from natural foods. This high caloric supplement occurs due to the high quantity of carbs in mass gainers.

And carbs are easily available in your kitchen, and we consume them in our daily diet. So if you want carbs, you can simply add simple high carbs rich food to your diet to stimulate more energy.

Carbs provide you energy during workouts while protein recovers and builds your muscle. With the energy given from carbs, we can do better exercises that break down our muscles even more.

It is easy to fulfill the requirement of daily carbs as compared to protein. So, it would help if you take whey protein in place of Mass Gainer.

    If you still want to use it, then consult your doctor first because it is a condition. Almost all brands have mentioned their products to consult the doctor before using if you are already suffering from any treatment.

A mass gainer is a complete meal that contains protein, carbs, fat, minerals, and vitamins. Due to its excess calories in one scoop, it can put loads on your kidneys. But you have to maintain your daily water intake level to have no problem in the digestion process.

Is it Ok to take mass gainers?

It’s not Ok to take mass gainers because you have the best alternate option, which is natural. Mass gainers provide you extra calories to gain mass, but that mass will get lost if you stop doing the workout for 1-2 months.

I have seen my friend gaining 5-10 kg in just one month, and after leaving workout for two months due to some reasons, he had loosed all the gains.

So, instead of using mass gainer, you should take natural foods to meet your daily carbs and protein requirement. To fulfill the protein need, you can use whey protein because it is not much high in calories but contain only protein.
