Powdered sweet orange juice (Citrus sinensis) is simply dehydrated juice, concentrated into a shelf-stable powder. It serves as a handy way to get vitamin C and can also add flavor to drinks and foods.
Some people use it to help maintain immune health and for its antioxidant content. The powder mixes easily into water, smoothies, or recipes, and often keeps longer than fresh juice.
Because it is acidic, it can trigger heartburn or acid reflux in sensitive individuals. However, sweet orange does not significantly block the CYP3A4 enzyme, unlike grapefruit. So it is not known to interact with statins or blood pressure drugs.
