Limes: A Citrus Fruit with Powerful Benefits

Limes: A Citrus Fruit with Powerful Benefits

Limes are bright green citrus fruits that are known for their sourness. But they’re also nutritional powerhouses — they are naturally high in vitamin C, antioxidants, and other nutrients that work to supplement your daily nutrition.

There are many species of limes, like the Key lime (Citrus aurantifolia), Persian lime (Citrus latifolia), Desert lime (Citrus glauca) and Kaffir lime (Citrus hystrix).

Each of these different species has unique characteristics, for instance, the Key lime is smaller, more acidic, and more aromatic than the more common Persian type of lime. In the United States, Persian limes are the most commonly available species found in grocery stores and at farmers markets.  

Because limes are loaded with nutrients, they can work to help boost your immunity, reduce heart disease risk factors, prevent kidney stones, aid iron absorption, and promote healthy skin, which is why we add them to our natural supplements and multivitamins. Check out our Immune Booster supplement to see how nutrients from limes can make a positive impact on your health.
