Buying Guide

The pervasive thought that women shouldn't buy weight gainers because of societal pressures and the idea that gainers are for bodybuilders and athletes is unfounded and untrue. The truth is that weight gainers are for anyone who wants to become more massive and stronger, including women.

Before you embark on this journey, here are some things that will help you purchase the right weight gainer and that it will be more comfortable to use.

Different Types

Weight gainers can come in various types and forms. The most common forms are as follows:

  • Powder
  • Softgels
  • Capsules

You will have to weigh several factors to decide which is best for you, such as if a milkshake is fine for you or would you rather have something else? Softgels can be a viable option for you, although they are less common on the market. It boils down to which form is most convenient for you. 

However, most people usually choose the powder form because it comes in various flavors like vanilla, strawberry, and chocolate.

Primary Ingredients

In general, for healthy weight gain, the supplement should consist primarily of carbohydrates and proteins. Moreover, protein is an essential element when choosing a weight gainer formula. The following will explain each essential element and its functions and benefits.


The two most prominent forms of protein are Whey Hydrolysate and Whey Isolate, and consequently, they're the two prevalent proteins used in the world of bodybuilding. These proteins are proficient at getting more mass inside the muscle while also enhancing the muscles' definition and shape.


Carbohydrates are the most efficient fuel source that our body uses for energy, especially when exerting ourselves. When consumed naturally, carbohydrates are in cookies, sweets, pastries, and other food items.

These energy sources are so proficient that, when used correctly, they can help you to gain a considerable amount of weight. A good protein to carbohydrates for building lean mass ratio is 3:1.


Creatine should be a contributing ingredient in nearly all quality weight gainers. However, it's not necessarily a deal-breaker if it's not present within a specific weight-gaining formula. There's the possibility that you can find a formula that works for you that doesn't include creatine. Otherwise, it's possible to get it through your diet via red meat or seafood.


Enzymes and their importance shouldn't be overlooked because they prevent poor digestion such as congestion or even diarrhea. Furthermore, they speed the process of digestion and stave ailments such as acid reflux and bloating.


Having good fiber inside of a weight gainer is integral to digestion because it helps to remove toxins. Fibers are proven to be an effective solution against unwanted toxins.

Minerals and Vitamins

If you are someone who consumes nutrient-rich meals or you already have a bevy of multivitamin options, then vitamins may not be a priority for you. However, if your nutrition is lacking, choosing a weight gainer with nutrient value in the formula should be a priority.

Here are some vitamins you should be looking to see: Vitamin C to improve the overall body immunity, vitamin A, vitamin B complex, Vitamin D, and Vitamins B6 and B12.

Zinc or magnesium should be among the minerals present within the weight gainer; these minerals are vital to your muscles and digestive system. In particular, magnesium helps muscles heal and relax after a strenuous training session that leaves your muscles sore and weak.

Too Much Sugar

The powder usually has a sugary element added to flavor it, such as vanilla, strawberry, or chocolate, to offset the unpleasant taste that the powder presents on its own.

Although sugar can cause you to gain weight, your weight gain should come from prescribed carbohydrates in the mix. Too much sugar can lead to imbalance and unforeseen complications with your results. 

The American Heart Association conducted a study that concluded women consume less sugar each day than men. They should not exceed six tsp a day, which is 25 grams and 100 calories.

Weight gainers typically include excessive sugar per serving. However, you should make an effort not to exceed your daily sugar intake by too much. Therefore, if your weight gainer is on the sweeter side, you can balance it out by not consuming sugary food items throughout the remainder of the day.

Weight Gainers vs. Real Food

Weight gainers should not be used to replace food completely, even if they're filling and help to energize you. However, weight gainer servings can give you upwards of 1,000 calories, so eating smaller meals throughout the day is fine.

However, it isn't a good idea to completely remove meals and survive on powdered shakes instead. You will be sure to have some sort of side effects if you abandon meals altogether.


As discussed earlier, weight gainers can cause side effects such as stomach cramps, diarrhea, bloating, acid, nausea, and even vomiting. For this reason, buying a weight gainer that comes with probiotics is an excellent idea to protect your digestive system. 

Probiotics are healthy bacteria found in dairy products such as yogurt. Probiotics regulate your gut flora by removing harmful bacteria and toxins that can complicate digestion and harm your stomach. Weight gainers with probiotics may cost a bit more money, but it may be worth it if you're prone to digestion and, however, you still want to put on mass.

Vegan Options

Finding a weight gainer supplement that is vegan and vegetarian-friendly can be difficult because most protein is sourced from animals. However, thanks to advances in science and technology, companies have succeeded in vegan-friendly weight gainers, which work just fine for women.

Once you've decided on a vegan-friendly weight gainer, check the ingredients to ensure that there are no obscure ingredients that originate from animals.
