Orange juice is a rich source of vitamin C, which is essential for various functions in the body such as immune system support, heart health, and collagen production. Vitamin C also acts as an antioxidant, protecting cells from damage caused by free radicals. However, the body does not naturally produce vitamin C, so it must be consumed through diet. Excessive consumption of vitamin C beyond 2,000 mg can lead to health issues like kidney stones or indigestion.

Some individuals may consume large quantities of orange juice, exceeding the recommended daily intake of vitamin C. However, consuming excessive amounts of juice can be high in sugar and lack dietary fiber, potentially leading to spikes in blood sugar levels and other health risks. Fruit juices also have a high acidity that can damage tooth enamel and cause heartburn.

Therefore, while orange juice can offer health benefits when consumed in moderation as part of a balanced diet that includes a variety of foods, extreme consumption as described by Osborne poses significant health risks. It is best to consume orange juice as part of a well-rounded diet that offers all the nutrients necessary for good health.
