What is Kudzu Root?

Kudzu root, sometimes known as Japanese arrowroot, is the root of the kudzu vine that is native to East Asian countries, including China, Korea, and Japan.

But these days, it is also growing in other parts of the world. Some people consider this plant an invasive weed as it grows over other plants and trees as a climbing vine. For centuries, Chinese medicine practitioners have used this starchy root due to its positive effects on inflammation, fever, and digestive problems, as well as diabetes and heart diseases.

Kudzu root is a rich source of several important nutrients that can benefit our health. For example, it contains high levels of isoflavones, a type of phytoestrogen that can help lower cholesterol levels and reduce the risk of heart disease. Additionally, kudzu root is a good source of protein, fiber, and various minerals such as calcium, potassium, and magnesium, which are essential for bone health and the proper functioning of the nervous and muscular systems.

Some studies also suggest that kudzu root may have anti-inflammatory and antioxidant properties, which may help protect against chronic diseases such as cancer and Alzheimer’s. However, researchers need to conduct more studies to fully comprehend the potential health benefits of kudzu root and its active compounds.

The Role of Kudzu Root in Weight Loss

Kudzu root has gained immense popularity among people who are looking for ways to shed extra pounds and maintain a healthy weight. One reason why it’s popular is that people believe it’s a natural remedy free of adverse side effects and safe to use. A few studies have also shown evidence to support the weight loss benefit of kudzu root. Can Kudzu Root Help with Weight Loss? Let’s explore a few health benefits of this root that may contribute to weight loss.

Kudzu Root Suppresses Appetite

One reason people gain weight is that they consume more calories than they can burn. When you eat more than your body needs, it stores all the extra calories as fat deposition instead of utilizing them for energy production. Kudzu root may help reduce your food intake and promote early satiety, leading to reduced calorie consumption and, ultimately, weight loss.

When you eat more than your body needs, it stores all the extra calories as fat deposition instead of utilizing them for energy production. The high fiber content of kudzu root causes it to absorb water in the stomach, expand to create a feeling of fullness, and suppress the desire to consume more food.

In addition, the kudzu root is a rich source of isoflavones, which also help suppress appetite. Various plants contain isoflavones that can mimic the effects of estrogen on the body. According to some studies, isoflavones can regulate appetite and reduce food intake.[1] The researchers suggested that the isoflavones in kudzu root may reduce the desire for high-fat foods and contribute to the overall decrease in calorie intake and weight loss.

Kudzu Root May Reduce Calorie Intake

Another way the kudzu root can help with weight loss is its suppressing effect on calorie intake. Kudzu root is known to have an amazing effect on reducing your desire for high-calorie food consumption. Using kudzu root or its extract can help you eat fewer high-calorie, fatty food, which is one of the major contributing factors in weight gain. With the immense popularity of fast food and dining out, this effect of kudzu root can have a tremendous impact on your weight loss journey.

Kudzu Root May Help Boost Metabolism

Metabolism is the measure of energy production from the food we eat. The body uses this energy to perform various bodily functions. However, people with a slow metabolism store most of the food they consume as fat, which can cause significant weight gain. This effect can be counter-balanced by eating foods that can boost the metabolism—a properly functioning metabolism results in effective energy production and utilization, resulting in weight reduction.

Although the research is still in the early stages, there are a few animal studies that show the positive impacts of kudzu root on boosting metabolism. For example, in one study, the researchers found that kudzu root extract can increase fat oxidation and reduce fat storage in rats who were given a high-calorie diet.[2] These results show that kudzu root extract can help reduce weight by boosting metabolism and inhibiting fat storage.

Kudzu Root May Help Regulate Weight Regulation Hormones

Along with calorie intake and metabolism, some hormones also play a crucial role in weight regulation. One of these hormones, leptin, is responsible for appetite regulation and metabolism, and the other, called ghrelin, is responsible for stimulating hunger. Kudzu root is known to regulate these hormones, which is another contributing factor in weight loss.

A few studies have proven the effects of kudzu root in hormone regulation. For example, in one study, the researchers concluded that the kudzu extract could reduce the levels of ghrelin, which can result in suppressed hunger and ultimately fewer calorie consumption. In addition, this study also found that kudzu root extract also increases the levels of leptin, causing a boosted metabolism and weight loss.[3]

How to Use Kudzu Root for Weight Loss?

If you are planning to start a kudzu root supplement to aid your weight loss, you should consult your healthcare provider first. This is especially important if you have a medical condition or are using any medications. Your healthcare provider can ensure if this supplement is safe for you and what dosage would work best for you.

Although some studies suggest a kudzu root dosage of 500 mg to 3,000 mg per day for a weight loss journey, there are no standard dosages for optimal weight loss. Consulting with your healthcare provider or nutritionist can best help you determine a dosage according to certain factors like your age, weight, and health status that will provide optimal weight loss results for you.

Here are some general tips for using kudzu root extract:

  1. Choose a reputable brand: Look for a high-quality kudzu root extract supplement from a reputable manufacturer. It is also a good idea to check for third-party certification to ensure that the supplement contains the stated ingredients and doses.
  2. Follow the instructions on the label: Always follow the recommended dosage and usage instructions on the label of the supplement. Do not exceed the recommended dose or use for longer than recommended.
  3. Take it with a meal: Kudzu root extract may be more effective when taken with a meal. This can also help to reduce the risk of gastrointestinal side effects.
  4. Be patient: Kudzu root extract may take time to show results, and it is important to be patient and consistent with its use. It is also important to remember that it is not a magic pill for weight loss and is best used as part of a comprehensive weight loss plan.
  5. Monitor for side effects: While kudzu root extract is generally considered safe, some people may experience side effects such as gastrointestinal discomfort, dizziness, or headache. If you experience any unusual symptoms, discontinue use and consult with your healthcare provider.
  6. Keep it out of reach of children: Kudzu root extract supplements should be stored in a cool, dry place and kept out of reach of children.

Furthermore, it is important to note that using kudzu root extract alone is unlikely to lead to significant weight loss. It is best used as part of a comprehensive weight loss plan that includes a balanced diet, regular exercise, and other healthy lifestyle habits.

Where to Find the Kudzu Root?

Kudzu root is easily available in online stores and natural food supplement stores. You can find kudzu root in various formulations, such as drink mixes, kudzu root extract drops, capsules, and tablets. In addition, you can also purchase it in the form of food-grade starch powder.


Kudzu root has the potential benefit of aiding weight loss by suppressing appetite, reducing calorie intake, boosting metabolism, and regulating hunger hormones, as shown by some studies. However, it is crucial to speak with your healthcare provider before starting any new supplement regimen, especially if you have any underlying medical conditions or are taking any medications.
