Yes, commercially available lemon juice like ReaLemon is made from real lemons. However, it's a concentrated and processed version of the juice.
Understanding "Real" Lemon Juice
The term "real" in this context is subjective. While ReaLemon and similar products start with real lemon juice, they undergo processing. This involves concentrating the juice to remove water and then adding filtered water back to restore it to a natural strength. Additionally, oil from the lemon peel is often added to enhance flavor.

ReaLemon's Process: ReaLemon and ReaLime are made with the juices of high-quality lemons and limes, concentrated to a uniform strength. Filtered water is then added to return it to its natural strength, and peel oil is included for flavor enhancement. (Source: ReaLemon and ReaLime website)

FDA Standards: ReaLemon meets or exceeds the FDA standard of identity for lemon juice, which is 4.5% w/w. (Source: A Gardener's Table)

Fresh vs. Bottled: While bottled lemon juice provides convenience and a consistent flavor, fresh-squeezed lemon juice offers a superior taste for some, with more nuanced and complex flavor notes. (Source: Reddit r/cocktails discussion)

Alternative Forms: There are also other forms of "real" lemon juice, including powdered lemon juice (like True Lemon), which offers convenience in another format.
Differences Between Fresh and Bottled Lemon Juice
While both are derived from lemons, key differences exist:
- Flavor Profile: Freshly squeezed lemon juice generally has a more complex and vibrant flavor profile than bottled juice.
- Nutrient Content: The processing of bottled lemon juice may slightly alter the nutrient composition.
- Convenience: Bottled lemon juice offers convenience and a longer shelf life than fresh juice.
Conclusion
Commercially available lemon juice is derived from real lemons, but it's a processed version. Whether it's considered "real" enough depends on your definition and preferences. The use of “real” in this context is relative and often linked to the degree of processing.
