You should only consume a glass of orange juice daily. That’s about 8 ounces a day. Children should consume fewer amounts, about 4 to 6 ounces of juice.

However, too much orange juice can create an imbalance and make you feel sleepy. It can lead to a sugar crash and extreme tiredness.

Orange has the right blend of vitamins and minerals that can help you feel better.

It is a known immune booster that lessens inflammation which is vital if you’re sick or suffering from the flu.
