We find a very exceptional exotic citrus. Thanks to their nutritional properties, they provide us with different benefits for our health.
Among them we can distinguish the following:
1. Antioxidant fruit
Although we are not aware, a constant battle between free radicals and antioxidants is unleashed in our body. The free radicals are molecules that are created naturally in our body and can damage cells.
In addition, they can cause oxidative stress when there are too many.  Here comes the role of antioxidants, neutralizing these molecules and helping to prevent aging and many diseases.
Therefore, it is important to maintain good health to eat fresh foods rich in antioxidants, such as fruits and vegetables.
Yuzu provides us with a large amount of vitamin C and other plant compounds with great antioxidant power. Being deals with carotenoids and flavonoids. In this study the antioxidant activity of the seed is detailed. 
In addition, limonene, which is a natural substance present in the skin of citrus fruits and also of yuzus, also acts as antioxidants. This study details how it helps reduce inflammation. 
2. For a healthy heart
Several studies show that the extract of this fruit can have anticoagulant effects by inhibiting the clumping of platelets. 
It seems that two flavonoids are the ones that notably favor this action. These are hesperidin and naringin.
Also, improving the flow of blood circulation helps to reduce the risk of heart disease. This is highlighted by various investigations. However, further research in this line has to be done to reach a more stable conclusion.
3. It can help our memory
Yuzu extract can be helpful in reducing brain dysfunction and improving memory . In addition, as this animal study demonstrates, yuzus extract improved brain function, among other benefits. 
4. Antibacterial effects
