Key takeaways:

  • Banana Drops, or banana liquid, is a liquid supplement that isn’t made from bananas.

  • There are no studies showing that Banana Drops help people lose weight. 

  • Other methods to maintain a comfortable weight include eating a high-fiber, plant-based diet and staying active. Medications can also help in certain situations.

What is Banana Drops?

Banana Drops is a liquid supplement marketed as a weight-loss aid. Manufacturers claim that Banana Drops — also called “banana liquid” — can help do the following:

  • Boost metabolism

  • Increase energy levels

  • Reduce appetite

  • Burn fat

Banana Drops isn’t actually made from bananas. It’s a combination of vitamins, minerals, herbs, and other botanicals. Each manufacturer uses its own combination of products. But one manufacturer states that its version contains:

  • Horse chestnut extract

  • Hawthorn root

  • Grape seed extract

  • Motherwort

  • Stone root

  • Gotu kola

All brands of banana liquid are considered supplements and aren’t regulated by the FDA. That means these products aren’t checked by the FDA to make sure they were safely made. They aren’t checked to ensure they contain the ingredients listed on the label and don’t contain additional additives or preservatives. 

So, these products haven’t been evaluated by the FDA to see how well they deliver on promises to help with metabolic health.

How do Banana Drops work for weight loss?

It’s not clear how Banana Drops works for weight loss. There are no published studies on Banana Drops. 

There are studies on some of the ingredients in Banana Drops. Most of these studies were done in mice though. Some mice lost weight while taking some of these ingredients. But there’s no solid evidence these ingredients have the same effects on people. In fact, one study cited by a Banana Drops manufacturer found that no herbal medicines were able to consistently help people lose weight. It’s not clear if taking a combination of herbal supplements makes any difference.

It’s even harder to find evidence that Banana Drops ingredients deliver on other promises like boosting metabolism and increasing energy levels.

How do you take Banana Drops for weight loss?

Banana Drops are easy to use. The liquid comes in a 60 mL bottle that’s topped with a 2 mL dropper. Most manufacturers recommend taking 1 full dropper (2 mL) by mouth once or twice a day.

You can squeeze the dropper directly into your mouth. Or you can mix the drops in a drink. You can even put it on top of food. 

Manufacturers suggest taking Banana Drops consistently for 3 to 6 months. It’s not clear how soon people can expect to experience results. There’s no way to know what the best and safest dose is for each person. 

What are the best natural supplements for weight loss?

Natural supplements can be a helpful tool for weight management. But there’s no good evidence that natural supplements alone can help people manage their weight. And sometimes natural supplements can lead to harm. Some supplements interact with medications and can cause unwanted side effects.

When it comes to weight management, there’s no one answer that works for everyone. Many factors play a role, including your genetics, overall health, and environment, as well as other factors. 

The right plan of care will use many tools to target these factors.

Work with your healthcare team to develop a plan that’s right for you. It may include supplements. But it can also include medications and other changes that can help you achieve the best metabolic health. 

The bottom line

Banana Drops is a liquid supplement that isn’t made from bananas. It’s made from a combination of herbs. Manufacturers claim that Banana Drops can help with weight loss, boost metabolism, and give you more energy. There are no studies on Banana Drops, so it’s impossible to know if it really works.
