Top 10 Best Weight Gainer Supplements

Top 10 Best Weight Gainer Supplements

For those looking to gain weight and muscle mass, we’ve identified our top 10 weight gainer supplements below. We’re confident that these mass gaining protein powders are the best options on the market, and welcome your feedback at the bottom of this post.

Gaining weight, oftentimes, can be just as frustrating as trying to lose it. As ironic as it is, the age old saying is true – “you have to eat big, to get big.” And for some (those with fast metabolisms) it seems virtually impossible to add muscle mass because it ends up getting burned off, seemingly faster than it’s put in.

One of the biggest obstacles to gaining weight is often due to an insufficient daily caloric intake. What that means in Layman’s terms is that your not eating enough.

After all, how does eating 3000 – 4000 calories worth of chicken, rice, and vegetables sound everyday? Training aside, that’s an obstacle in itself. Weight gainers were designed with this in mind – to be a quick, convenience, and high-quality alternative, packed with large amounts of proteins, carbohydrates, and calories per serving.

Keep in mind, weight gainers are different than your standard protein shakes. With higher amounts of protein, carbs, and calories, the top 10 weight gainers below help to support the following:

  1. Faster muscle growth
  2. Increased workout recovery rate
  3. Prevention of muscle catabolism between workouts

* All Protein, Carbs, and Calorie are listed as “per serving”

Best Mass Gainer Supplements

#1 Transparent Labs MASS GAINER Protein with Grass-Fed New Zealand Whey

Weight Gainer Supplement
When you want to gain some serious muscle mass you need an excess of protein, carbohydrates, and fats. But you know all about macro-nutrients already. Once you meet those macros though, there is no guarantee that your going to be happy with the quality of the weight you put on.

Straight macros alone isn’t going to cut it.

Instead, you need to get those proteins, carbohydrates, and fats from half decent sources. Transparent Labs MASS GAINER protein is probably the only weight gainer supplement that meets the criteria of a healthy source.

Each serving of MASS GAINER protein contains 750 calories from 53 grams of grass-fed New Zealand whey concentrate, 109 grams of carbs (100 g from organic maltodextrin), and 6 grams of fat.

In terms of weight gainer proteins, MASS GAINER is a bit pricey. But, the quality of this protein powder heavily outweighs the $65 price tag. To make this a true value, the SD team requested a discount for our readers. So, by using discount code “supplementdemand” you can save 10% and get MASS Gainer for $58.

#2 Pro Complex Gainer by Optimum Nutrition

Optimum Nutrition has long been known for its weight gainer and protein supplements, and for very good reason!

Optimum Nutritions Pro Complex Gainer reminds us to not judge a gainer based solely upon its calories per serving.When it comes to obtaining lean muscle mass, not all calories are created equally.
