Apple juice can be useful for rehydrating when you're sick. Its disease-fighting plant compounds may also protect your heart and brain as you age. However, apple juice is not very filling compared to whole apples, nor does it offer much fiber, vitamins, or minerals.

• May Improve Heart Health

Potassium might be present in higher concentrations in this juice, which is good news for your heart health. Potassium can be a vasodilator, which means it can lower tension in your arteries and blood vessels. It might help in relieving pressure and strain on the cardiovascular system. Moreover, apple juice might prevent cholesterol formation in your arteries, which is often the major reason for heart attacks and other cardiovascular ailments.

• Might Boost Immunity

Apple juice might have a notable amount of vitamin C, a key component of the body’s immune system. Vitamin C can stimulate the immune system, thereby functioning as an antioxidant compound that prevents oxidative stress and reduces inflammation.

• Might Give Relief from Constipation

Apples might contain malic acid, which may improve the digestive rate and can support liver function. In combination with fiber and other stimulating minerals in apple juice, this juice might relieve symptoms of constipation, cramping, bloating, and diarrhea. Furthermore, it also might contain sorbitol which may help in smoothing the digestive tract, thereby easing the movement of stool.

• Skin Care

Apples can be consumed in a variety of ways, such as fresh fruit and as a juice that is further processed into apple vinegar, apple cider, or distilled. Packed with antioxidants and vitamin C, apple juice is beneficial for the skin. It helps in reducing inflammation, itching, and wrinkles. Furthermore, it also prevents premature skin aging. 

• Protect Brain Health

Antioxidants are known to prevent oxidative stress in the body. According to a 2011 comprehensive study in the Advances in Nutrition journal, apple juice may have the potential to lower the risk of Alzheimer’s. Another 2010 study showed that antioxidants present in this fruit juice may help relieve symptoms of neurological diseases.

• Boosts Metabolism

Long-term research may have linked the consumption of apple juice with smaller waistlines, lower levels of body fat, lower cholesterol levels, lesser risk of diabetes, and lower blood pressure, all of which are risk factors known as metabolic syndrome. For this reason, apple juice can help optimize your metabolism and might protect your heart.

 

• Improves Liver Function

As mentioned, malic acid can improve liver function. Apple juice, when combined with water, might stimulate urination and may promote the release of excess salts and fats from the body. The alkaline content can also help in flushing out toxins, maintaining a good pH balance in the body, which thereby may be acting as a liver cleanser.
