Potential Uses of Guava juice: 

Guava juice may have potential uses for various health conditions; however, more human studies are required to suggest its true extent in humans.

However, this information is insufficient and therefore, we require more human studies to suggest the benefits of guava juice on human health. And if you have high blood pressure, consult your doctors for appropriate diagnosis and treatment.  

2. Potential uses of guava juice for diabetes 

Guava juice may have a blood sugar-lowering activity. It may reduce insulin resistance in persons with diabetes. An animal study (Cheng and Yang. 1982-83) observed that oral intake of guava juice significantly lowered animal blood sugar levels. They found that the essential components of guava juice, such as flavonoids, quercetin, dietary fibre pectin, ursolic acid, etc., were responsible for regulating blood sugar levels and slowing down glucose absorption in the body. Hence, people with diabetes mellitus may use guava juice to manage high blood sugar.1  

However, these observations were made during animal studies and hence, further human trials are needed to support its scope in human beings. Therefore, before using guava juice, speak with your doctors and only use it in therapeutic quantities if recommended. 

3. Potential uses of guava juice for weight loss 

Guava is a good source of vitamins, proteins, minerals and dietary fibre (pectin), which may aid the passage of food and solid waste product through the gut. In addition, guava juice has no cholesterol and traces of carbohydrates. Therefore, it may provide significantly less sugar if you drink raw guava juice compared to other fruit juices. This probably helps increase the proper absorption of nutrients and regulate the metabolism.1 Hence, you may add guava juice to your weight loss regime. However, do not use it to self-medicate on your own; it is better to consult a doctor.
