Celery juice, a trending drink among health-conscious consumers, offers potential benefits for hydration, blood sugar control and heart health but also carries some risks, experts say.
The juice is approximately 95 percent water and contains significant potassium, an electrolyte that helps the body maintain fluid balance, according to Health. Regular consumption may help keep the body adequately hydrated.
Unlike many other juices, celery juice is low in sugar and carbohydrates, according to United States Department of Agriculture data, meaning it does not cause sharp spikes in blood sugar. It may also improve insulin sensitivity, and its magnesium content can help glucose enter muscle cells more efficiently, supporting more stable energy levels throughout the day.
Better blood sugar control may in turn reduce the risk of inflammation linked to diabetes and heart disease, according to research on plant-based diets and phytochemicals.
Celery is a rich source of antioxidants, including the natural compound apigenin. Preliminary research suggests these antioxidants may support brain health by reducing cell damage and inflammation, according to a review on celery in neurology. Early studies also point to potential benefits for blood pressure, heart function and joint health.
The juice may help lower blood pressure by keeping blood vessels dilated. Celery also has a mild diuretic effect, which may further support healthy blood pressure levels.
Risks to consider
Natural compounds called psoralens can increase skin sensitivity to sunlight in some people. Those with birch pollen sensitivity may experience allergic reactions including itching, rash and swelling around the mouth and lips; in rare cases, difficulty breathing can occur.
The juice may also interact with blood-thinning medications due to its high vitamin K content, and it contains less fiber than whole celery because the pulp is removed during juicing.
