If you have kidney problems, a history of kidney stones, or you’re on blood pressure medication, beetroot juice isn’t worth the risk. Same goes if you have iron overload conditions like hemochromatosis—beetroot juice contains iron, and too much of it can be genuinely dangerous for you. Pregnant women should be cautious too. While small amounts are probably fine, going heavy on beetroot juice when you’re pregnant isn’t worth experimenting with.
People with sensitive digestive systems need to be realistic. If your gut already struggles with fibrous foods or concentrated liquids, beetroot juice is going to make things worse, not better. And if you’re diabetic, pay attention to how it affects your blood sugar. The natural sugars in beetroot are still sugars, and they can spike your levels.
