Long celebrated for its tangy flavor and refreshing aroma, lime (Citrus aurantifolia) is emerging as more than just a culinary staple. Nutritionists and health experts say the fruit is packed with medicinal, nutritional, and cosmetic benefits that make it a “superfruit” with wide-ranging applications—from weight management and skin care to disease prevention.
According to the USDA National Nutrient Database, a single serving of lime (about 67 grams) provides just 20 calories while delivering 32% of the recommended daily intake of vitamin C. Limes are also rich in potassium, magnesium, folate, vitamin A, vitamin E, vitamin K, and soluble fiber.
Their peel and pulp contain antioxidants, flavonoids, and phytochemicals such as limonene and terpenes, which contribute to their healing properties.
Boosts Immunity: High vitamin C content strengthens the body’s defense against infections, coughs, colds, and diseases like malaria and diarrhea. A 2017 study in Nutrients confirmed vitamin C’s role in enhancing immune response.
Aids Digestion: The fruit’s natural acids stimulate digestive enzymes and bile production, improving gut health and preventing constipation. Its roughage content adds further relief from digestive discomforts.
Promotes Weight Loss: A 2010 animal study suggested that lime essential oils may reduce appetite and prevent weight gain, while citric acid aids fat metabolism. Drinking warm lime water before meals is a traditional weight-loss remedy.
Improves Skin & Hair Health: Lime juice, rich in antioxidants and vitamin C, helps reduce acne, blemishes, wrinkles, and dark spots. When applied to the scalp, it promotes dandruff-free, shiny hair. Lime essential oil is also widely used in cosmetics and aromatherapy.

Manages Diabetes: With its low glycemic index and high soluble fiber, lime helps regulate blood sugar and reduce glucose spikes. The American Diabetes Association lists citrus fruits like lime as diabetes-friendly.
Supports Heart & Kidney Health: Potassium in lime aids kidney function, while citric acid may help dissolve kidney stones. A 2014 study in the Korean Journal of Urology found lime juice effective in reducing stone recurrence.
Protects Against Gout & Arthritis: Lime’s antioxidants and citric acid help break down uric acid, reducing joint inflammation.
Fights Oral & Gum Diseases: Flavonoids in lime have antibacterial properties that may prevent gum bleeding and infections.
Prevents Anemia: Vitamin C enhances the absorption of iron from plant-based foods, helping people with iron-deficiency anemia.
Experts caution that excessive consumption of lime can erode tooth enamel due to its high citric acid content. Direct application on skin may also increase sensitivity to sunlight, causing phytophotodermatitis. Washing the peel before use is strongly advised to avoid bacterial contamination.
From combating chronic diseases to enhancing beauty regimens, lime has proven to be more than just a zesty fruit for garnishing meals. Health experts recommend incorporating lime into daily diets—whether as juice, zest, or in warm water—to harness its wide spectrum of benefits.
