Gaining weight can be challenging and confusing. Generally, in order to gain weight, you need to consume more calories than you burn. Drinks like Ensure can help you consume more calories throughout the day, which can then help you gain weight.

Ensure is an oral nutrition supplement (meaning a drink that provides extra nutrition) that can help people with their weight goals, whether they are looking to gain weight or lose weight. 

If you or someone you know is struggling with poor appetite, weight loss, or difficulty eating, Ensure may be a great option. 

Ensure isn’t your only option though. There are also other healthy ways to gain weight, which we share about here and here. Continue reading to see how Ensure can help you gain weight. 

What is Ensure?

Ensure is a brand of drinks that are designed to help people get additional nutrients.

Ensure drinks are nutrition supplements, and are often recommended by doctors and registered dietitians to help people who struggle getting enough nutrients through only their food. 

It has been shown that oral nutrition supplements, like Ensure, can benefit people with poor appetite and weight loss. (1

Ensure has a good amount of calories in a small amount of volume. It can help you consume more calories throughout the day without filling you up too much. 

Boost is another brand of oral nutrition supplements which you may have heard of and protein powders are also considered nutrition supplements, and can help people gain weight the same way Ensure does.

You may be given Ensure in a healthcare setting, like the hospital, but you can also buy it at major grocery stores, pharmacies, and online. There are lots of different kinds of Ensure drinks, so it’s important to pick the one that’s right for you. 

What are the Differences Between Ensure Drinks?

While all Ensure drinks provide calories and protein, there are slightly different versions of each, and they come in all kinds of flavors. Here are the different kinds of Ensure drinks along with some additional information about them.

How Does Ensure Help You Gain Weight

In general, weight gain occurs when people eat more calories than their bodies need.

Some people struggle to gain weight due to poor appetite, difficulty eating, or they burn more calories than they consume throughout the day. 

Ensure provides calories and protein in a relatively small amount of volume, which can help people get more nutrition in addition to the food they’re eating. 

You can use Ensure as a meal replacement, but if you are trying to gain weight, it may be better to drink 1-2 throughout the day in addition to your meals and snacks.
