What to Look for in Weight Gainers?

Weight gaining supplements are different from the usual protein powders. The main difference is that weight gainers contain protein plus carbs and fats.

Many people get confused with this. All too often they get disappointed when they find out their mass gainer contains carbs when what they really want is a protein shake powder.

Vital Components of a Lean Weight Gainer Product

You need proteins when you want to build lots of lean muscle. If you want to gain weight and mass quickly as well, then you need lots of calories both from protein, carbs, and fats from the best weight gain supplements you can find.

Taking weight-gain supplements with plenty of carbs will help you gain muscle mass because your body will use it for energy instead of having to resort to breaking down proteins from your muscles. Fats are also an excellent energy source and aid in the absorption of essential vitamins like A, D, E, and K.

Many types of weight-gain supplements will help you load up with the massive amounts of calories that you need to build body mass, and also benefit from more efficient vitamin and mineral absorption.

Check Protein Quality

When you choose your gainer, you first look at the quality and amount of protein it contains. This is shown as the BV or biological value. Higher BV values mean the protein content is higher and more easily digested and absorbed.

Higher BV values mean the protein content is higher and more easily digested and absorbed.

For instance, whey isolate has BV 159 while milk protein casein has BV 77. Whey isolate is more readily absorbed and easier on the digestive tract than casein.

Lower BV proteins tend to be of less quality. However, it does not mean you have to stay away from these.

You can take weight gain powder with low BV values when you want slower protein absorption. One example is when you want to take the weight gain shake before going to bed and make sure the protein is absorbed during the whole night.

High-quality protein with a high BV value is best used after workouts to refuel muscles with amino acids needed for muscle building.

Check Carb Amount

Next thing to check is the amount of sugar och high GI carbs is in the gainer supplement. This is in terms of carbohydrates.

Too much carbs at one time can cause too high insulin spikes. This can lead to symptoms such as irritability, headaches, and drowsiness.

Insulin spikes will lead to more fat storage. This might also affect your appetite and will interfere with building muscle and safely gaining body weight. Insulin spikes are ok after workouts though when most of the carbs will be used for muscle repair instead of going to fat storage.

The ideal amount of carbs in mass gainer supplements is around 30 to 60 gram of protein. If you can handle carbs well there is however no reason you cannot go higher then that.

Check Fat Content

You now know what kind of protein to look for and how many carbs should be there. How much fat then?

The ideal ratio is two times more proteins than fats, and carbs twice as many as proteins. Our favorite type of fat for lean super mass gains is MCT (medium chain triglycerides) because they have a tendency to result in less fat gains and are quickly converted into energy by the liver.

Conclusion

Bulking up fast even when you’re very skinny is possible with the use of the right weight gainer supplements. There are several on the market that caters to many individual needs, preferences, and conditions.

Proteins and carbs work together for optimized training, muscle repair, and post workout recovery. Fats work for sustained energy and more rapid absorption of some vitamins into cells.

Taking into consideration the pros and cons of each product in this list, our favorite product is LESS NAKED MASS since it contains the essentials and offer a clean and organic product. Don't compromise your health with downing lots of calories from products containing many artificial ingredients and additives.
