In a market that is dominated by weight loss supplements, it’s a bit odd to run into a weight gain supplement. Despite the weirdness, many people want to gain weight whether to bulk up in the gym or for other reasons. Weight gain supplements are designed to help you put on pounds and keep them. 

CB-1 is a weight gain supplement designed for both men and women. CB-1 claims itself to be clinically tested and that it has been proven to help you put on weight. 

We cover a lot of weight loss supplements here so let’s try something new. Today we are going to talk about CB-1 and see if it can make good on its promises. 

CB-1: Overview

CB-1 Weight Gainer

CB-1 is a weight gain product derived from natural products. Among other benefits, CB-1 claims that it can support a healthy metabolism and increase your appetite. Each pack of CB-1 contains 90 capsules, which is enough for a 30 day supply. The instructions say you are to take one pill before each meal. 

CB-1 claims that all of its ingredients undergo third-party testing to determine veracity but we could not find any links to confirm those claims. The manufacturer also says that all their products are created in an FDA approved factory. CB-1 is made with ingredients meant to help you put on weight. It contains ingredients to stimulate hunger and other ingredients to create body mass.

CB-1 does not contain any drugs or steroids and everything in it can be found in other supplements on the market. The company guarantees that it is safe for sport and is suitable for people of all ages, even children. Of course, at the bottom of the site is that ever-important disclaimer that says none of the product’s claims have been tested by the FDA. 

We should mention that if you are having trouble gaining weight, you need to figure out the root cause first. See your doctor first as low weight gain can be signs of other medical issues.

Who Makes CB-1?

CB-1 is created by Supragenix, a nutritional supplement company. Unfortunately, Supragenix does not have much internet coverage so we were unable to find out who its founders are or when it was founded. The company does have a BBB page but it is not accredited. There are a handful of complaints on the page but the company seems to have responded to all of them. 

Otherwise though Supragenix has a low profile on the internet. Normally, we take that as a bad sign. We also could not find any customer reviews on the product website. When a supplement company does not have a sizable internet presence and does not allow customer reviews on their website, we get a bit skeptical. 

How Does CB-1 Work?

CB-1 Weight Gainer Guide book

According to their website, CB-1 was put through an 8-week randomized clinical trial. Participants in this trial gained an average of 3 pounds after 4 weeks when taking the supplement. After an additional 4 weeks, the participants had still managed to keep on the weight. Supragenix does not give a link or citation to this claimed study anywhere on their website which makes us believe they are exaggerating or just making it up. 

Here’s another problem too: The website says that you need to maximize your calorie intake to get the most weight gain benefits while taking CB-1, but that is also how you are supposed to gain weight without taking CB-1. In other words, if the subjects gained weight in the study, it’s not clear if the weight gain was because of CB-1 of just because participants were eating more than usual. 

Either way, the study seems to imply you can expect to gain about 4 pounds per every 2 months. That is not exactly stellar results. The product does come with a weight gain guide book, which is nice, but not worth much if it doesn’t actually help you gain weight. 


CB-1 contains some pretty common ingredients in vitamin supplements. Here are some of the major ones:

  • Vitamin D3
  • Vitamin E
  • Soy Lecithin
  • Zinc
  • Echinacea Purpurea Powder
  • Echinacea Angustifolia Powder

Vitamin D3 is the so-called sunshine molecule. Vitamin D3 helps strengthen bones, teeth, and can help nerve function. Vitamin E is an antioxidant that can soak up free radicals that cause cellular damage. Both of the ingredients are good and needed by the body, but there isn’t evidence that they help with weight gain. 

Soy lecithin is a common food additive. It may have some benefits for the heart, brain, and liver, but there is little evidence on this point. Zinc is an important nutrient that regulates bodily functions. Zinc is also an antioxidant, but there is no evidence that it supports weight gain. 

Those last 2 weird sounding ingredients come from two plants in the sunflower family. Both of these ingredients are linked to a boosted immune system and lowered stress, but not weight gain. 

Side Effects and Safety

Most of the ingredients in CB-1 are mild and have no noticeable side effects. Purpurea powder and Angustifolia powder are known to cause nausea, vomiting, stomach pain, or diarrhea. 

Where to Buy CB-1 and Cost

CB-1 Weight Gainer Website

You can buy CB-1 from Supragenix’s website or from Amazon. It does not seem to be available in physical retail stores. A 90 capsule 30-day supply costs $49. 

CB-1 Weight Gainer: Does it Work?

Unfortunately, we are going to recommend passing over this one. The lack of customer reviews on the website and the negative reviews elsewhere make us skeptical that CB-1 helps you gain weight any more than eating more food does. If you need to gain weight, it might be more effective to talk to your doctor and figure out a new diet plan or see if you have an underlying condition.
