When Should You Take Mass Gainer?

When you should take mass gainers all starts with understanding your body’s needs at different times of the day.

And the best time to fuel your body is when it runs low on nutrients, which makes the following timings ideal for taking mass gainers:

Your body is usually nutritionally deficient at these times and fueling it with a mass gainer enriched with all the essential vitamins, minerals, proteins, carbohydrates, and salts, will not only give you that much-needed jolt of energy to hit the gym or start your day but also put on some healthy muscle mass.

And no doubt, a mass gainer can help you build a lean physique in no time, but if you want to gain the most from a mass gainer, you need to pair it with the right workout as well.

You can take a mass gainer before or after the workout—but according to research studies and real-life experiences of those who have tried, post-workout is usually the best time to take it.

As you scroll down, I will unveil several research-backed reasons why taking mass gainer after a workout is considered more favorable.

Mass gainers are a blend of carbohydrates, proteins, and healthy fats.

Studies have found that the timing of protein ingestion does not influence your muscle protein synthesis. But, the timing of carbohydrates does have an impact on muscle growth.

According to an article published by the National Library of Medicine, carbohydrates intake right after exercise results in a super-compensation of glycogen stores while delaying consumption by just 2 hours reduces the rate of muscle glycogen re-synthesis by up to 50%.

You might be wondering what glycogen has to do with weight gain.

Well, a significant quantity of water is held by glycogen; 1 g of glycogen contains 2.7 g of water. As a result, if you consume more carbohydrates, your body will retain more water.

This extra water is not the same as water retention, in which excess water is stored between cells; the water bound to a glycogen molecule is inside the cells, making them healthy.

Nonetheless, it can boost your body weight by 3 to 5 pounds. Because this weight gain is only water weight and not fat weight, the athlete or fitness enthusiast who encounters it should not fret.

No wonder why carbohydrate to protein ratios of 2:1 or 3:1 are also typically used for post-workout recovery.

This is what makes mass gainer a perfect drink after a workout.

But all this does not negate the wonders protein does in reducing muscle damage and enhancing muscle growth.

Some brands also add electrolytes in their mass gainers, and our body is in dire need of them after a workout, So it replenishes our body with electrolytes.

Moving forward, let’s find out if you can take mass gainer while doing a workout.

Can I take a mass gainer during a workout?

Well, the answer to this question is a resounding yes!

You might find it strange, but it is not a bad idea to fuel up your body during long strenuous exercise with a high-calorie supplement.

But don’t forget your body is a machine, and the machine needs PRECISELY the right amount of fuel to keep running. If you try to overfill it, it will spill out the excess. So taking it within a limit is a key to avoiding puking.

However, if you have a weak gut, it is recommended to avoid taking mass gainer during exercise because it may cause gastrointestinal distress as it is rich in carbohydrates.
