3 Reasons Why You Should Use A Weight Gainer

We want to help you understand your body’s needs so you could choose the weight gainer that best suits you. If you’re still undecided whether to start taking a weight gain supplement or not, here are three important reasons why you should use a weight gainer.

1. To help fulfill calorie requirements

Calories are the stuff that makes you gain weight. Thus, it is important to know the amount of calories that you need per day. According to the American College of Sports Medicine, the average caloric intake for women should not fall below 1,200 a day.

Calorie requirements also vary according to age. For women between 19 and 30 years old, the average requirement is 2,000 to 2,200 calories a day. On the other hand, women aged 31 to 50 years old need a minimum of 2,000 calories per day while those older than 50 years require about 1,800.

Most weight gain supplements contain a thousand calories in every pack. With regular intake, you could easily achieve your minimum calorie requirement.

2. To gain weight without getting fat

Most people confuse gaining weight with getting fat but this is not necessarily the case. Sure, you will gain weight when you get fat but there is a healthier and leaner way to increase your body mass.

Weight gainers are packed with specially formulated fats. This particular type of fat keeps you lean while also promoting your body’s muscle-building process. Additionally, it is recommended to choose weight gainers that contain the least amount of saturated fat, as this is the kind of fat that increases “bad” cholesterol.

3. To produce creatine more efficiently


Creatine is one of the chemicals required to create adenosine triphosphate (ATP). ATP is the substance that provides energy for the cells.

Research has shown that taking creatine supplements may enhance physical strength and quickens muscle recovery, so it is no wonder why it is very popular among athletes and gym buffs.

The additional creatine provided by weight gainers is another reason for you to take it since gaining weight requires both diet AND exercise. Creatine gives you more energy and helps you last longer during workout sessions. It also speeds up muscle recovery, allowing you to hit the gym more frequently so you could build more muscles, which increases your weight.

Creatine is usually sold separately but there are available products that combine creatine with protein shakes or meal replacements so you could hit a few birds with one stone.

What You Should Know Before Buying

A crucial tip in making any purchase is to first understand what you are buying. In choosing the right weight gainer for you, you should know the breakdown of the key ingredients and their functions so you could make the most of your weight gainer.

  • Protein

Protein is the main building block of muscles. As you build muscles, your total mass also increases. The recommended protein intake for women is 46 grams daily, and weight gainers usually contain 50 grams of protein in each serving.

  • Carbohydrates

Carbohydrates are the body’s primary source of calories. To gain weight, an average woman needs to eat more than 2,000 calories per day.

  • Other ingredients

Weight gainers also contain ingredients that don’t necessarily make you gain weight but they help in maintaining metabolism, such as vitamins and minerals.

Most brands also include branched-chain amino acids or BCAAs. This kind of amino acids provide energy. According to the Journal of the International Society of Sports Nutrition, BCAAs stimulate protein synthesis to develop muscles, which increases your weight.


In terms of muscle bulk and overall body mass increase, the weight gainers on this list have almost similar features. However, comparing each product’s benefits versus bang for your buck, the Optimum Nutrition Gold Standard 100% Whey Protein Powder emerges as the best weight gainer for women.

Each serving is packed with high concentrations of protein, calories, and BCAAs, which are key components in creating new muscle tissues and increasing overall body weight. It also features enzyme additives which help with digestion, which is a big plus as whey protein powders are usually strong and may upset sensitive stomachs.
