The Recommended Dosage of Mass Gainers

How much to take will depend on the product you buy. It’s best to just follow the instructions given on the product label. Given below is a general guideline for workout supplements that are aimed to boost energy, metabolism, workout endurance and performance. (3), (4)

You can take the first dosage in the morning. The next one can be taken at least 1 to 2 hours before the workout session. This will enhance your performance through your training routine. 

The last dosage should be used as post-workout nourishment. Post-workout nourishment is required as the muscles are depleted of energy and require nutrients for repair and recovery. (6), (7)

The Risks and Side Effects of Mass Gainers

It’s advisable to consult your physician before using a mass gainer. This will help you avoid side effects and guide you in achieving your health goals. Just like all supplementary diets, there are side effects to a mass gainer as well, especially when it is not used appropriately. 

  1. Most mass gainers contain creatine that may cause gastrointestinal problems. The intake of creatine requires sufficient amounts of water. If the water intake is inadequate, muscle cramping may occur. (8)
  2. Carbs along with whey supplementation have the potential to cause gastrointestinal distress. Have a quick check on the list of ingredients and be aware of the amounts of these compounds that are present in the mass gainer product. 
  3. There could be a body fat increase. You should not be under the impression that a mass gainer will convert calories into muscles. It can increase the fat in the abdominal region (adipose tissue), especially if not accompanied by regular and intensive training. You would have to burn more calories than you consume. (9)
  4. Mass gainers may have a role in the development of type 2 diabetes. Most mass gainers contain a high content of glycemic index carbs. The consumption of these carbs over a long period of time contributes to the creation of insulin resistance.(10) This is a precursor to the chronic medical condition of type 2 diabetes. 
  5. A mass gainer can cause constipation. These supplementary foods have high-calorie and low-fiber content. Research has long been advocating the intake of fiber for a good bowel movement. Low-fiber is a risk factor for chronic constipation.

Frequently Asked Questions (FAQs) About Mass Gainers

How to Choose a Mass Gainer?

Check for the right ratio between carbs and proteins in the product. The formulation should have a ratio of 3:1 complex of carb to protein. The digestion of complex carbs takes more time and therefore will supply you with enough energy to complete your workout routine.

The number of calories will supply you with energy to push through your routine. The right proportions of good fat content and micronutrients will make the mass gainer a holistic dietary supplement.

Is Creatine Bad for Health?

No, Creatine is not bad for your health. Creatine serves many health benefits that have been scientifically verified (11). But overdosing on creatine will cause undesirable side effects. The best mass gainers do not contain high amounts of creatine in a serving.

Creatine taken in high doses may damage the liver, kidneys or heart. It can also cause muscle cramping. If you are stacking multiple supplements, ensure you are not overdosing on any particular ingredient. It’s best to consult a physician for guidance, especially if you are on any medication.

The Final Note

There are many types of bodybuilding supplements in the market. If your health goal is to gain a muscular body and gain weight through workouts and rigorous exercise then a mass gainer will be beneficial. If you desire to chisel out all the additional fat from your body and want to build muscles then you should choose a whey protein supplement rather than a mass gainer. 

For people who struggle to gain weight and are unable to eat enough, a mass gainer will be helpful. Calorie intake can be substantially raised. 

Mass gainers are rich in proteins, carbs and other nutrients like amino acids, vitamins, and minerals. They help to bulk up and build muscle mass in bodybuilders. So take a closer look at the above top 10 mass gainers and choose the one that suits your needs the best.
