Calamansi, also known as calamondin, Philippine lime, or Philippine lemon, is an economically important citrus hybrid predominantly cultivated in the Philippines. It is native to the Philippines, Borneo, Sumatra, and Sulawesi in Indonesia in Southeast Asia, as well as southern China and Taiwan in East Asia.

Calamansi (also known as kalamansi and calamondin) is a small citrus fruit, with bright orange flesh and a peel that goes from green to orange as it ripens. It tastes sour with a hint of sweetness, like a mix between a lime and a mandarin.

11 Health Benefits of Calamansi

My family grew up drinking calamansi juice almost every day. My Mom would always have a pitcher or two of the calamansi juice in our house so we can always have it ready to drink. We were never brought up to drink any sodas or soft drinks and so the calamansi juice was always a part of our daily intake.

My Dad also had it every single day with his diet. It was so refreshing to drink it, especially when it is icy cold. My country is always hot and so it is a more nutritional drink to have than other artificial packaged drinks or sodas.

1. Immune Booster

Packed with vitamin C and other beneficial nutrients, calamansi juice has been used as an immune booster for generations. Despite its high levels of citric acid, many people drink it as a soothing substance for the stomach.

Another good thing about calamansi is that it strengthens the immune system. Shaikh wrote: “Calamansi has good amounts of minerals and vitamins, especially vitamin C which is essential to building immunity. It provides immunity against viral and bacterial infections. Drinking this juice on a regular basis helps build immunity against the common cold, flu, and fever.”

Now the other side of the coin. While calamansi juice has numerous health benefits, Shaikh warned that it should not be consumed in excess, especially during pregnancy. “Citrus fruits like lemon and calamansi can trigger heartburn during pregnancy,” she explained. “Also, citrus juices may cause stomach cramps, indigestion or diarrhea if consumed in excessive amounts.”

2. Weight Loss Drink.

People who want to lose weight might consider drinking calamansi juice. “This tropical juice is legendary for its impact on weight loss, as it has the ability to not only boost the metabolism but also eliminate many of the toxins in the body that can contribute to fat storage,” said the website of Organic Facts.

“By increasing metabolic speed, this juice can improve passive fat-burning throughout the day, while detoxifying the body will help all of your organ systems run more smoothly and function properly, aiding in calorie burning. By reducing fat storage, you will have more usable energy and less adipose fat formation. Many people drink a glass of calamansi juice every morning to stimulate the body and achieve weight-loss goals,” the website adds.

3. Controls Cholesterol Levels.

Calamansi can also help control cholesterol levels. This is good news, particularly for those who want to lose weight. More important, Organic Facts claims calamansi can “also help lower your risk of atherosclerosis, heart attack, and stroke.”

4. Lowers Body Acidic Content

Curiously enough, while calamansi is known for its acidic content, it can reportedly help lower acidity. “Despite the high levels of citric and acidity of this fruit, many people drink it as a soothing substance for the stomach,” the Organic Facts says, citing a study published in the Journal of International Oral Health, which throws light on the anti-inflammatory property of tannins from the rind of calamansi.

5. Lowers level of Inflammation.

“Calamansi can lower levels of inflammation when consumed in moderation, lower your risk of developing ulcers and protect you from acid reflux disease,” the website points out.

6. Helps Control Diabetes

Here’s good news for those who are susceptible to diabetes. Calamansi has been found to help control diabetes. A study cited in the International Journal of Science and Research has been done on the blood sugar-moderating effects of calamansi juice. “It can help regulate the release of glucose and insulin into the bloodstream, which is excellent news for those suffering from diabetes or those at risk of developing the disease,” the website says.

7. Aids in Preventing Oral Problems

Another website, maintained by Foods for Better Health, calamansi prevents oral problems. In preventing oral problems, calamansi juice can be used as a mouthwash. “Vitamin C from this juice helps prevent tooth decay, bleeding gums, gingivitis or loosening of teeth,” wrote Farah Shaikh, author of the report. “It helps remove stains and plaque.”

8. Helps in Keeping the Kidney Healthy.

When taken regularly, calamansi juice keeps the kidney healthy. “It reduces foul urine odor and lightens its color,” Shaikh claimed.

9. Helps Improve Bowel Movements

“Regular intake of the juice also purifies the organs and detoxifies the colon. It improves bowel movement and relieves constipation.”

10. Aids in Collagen Production

Calamansi also increases collagen production. Vitamin C, which calamansi is loaded, is a crucial element in collagen production, which is the compound needed to create every tissue, muscle fiber, and cell in the body. “Collagen acts as a cement to bind loosely connected cells and tissues; this way, it is able to prevent signs of aging like wrinkles,” wrote Josephine Mills in an article titled, “Calamansi Health Benefits.”

11. It Acts as Skin Bleacher

“Calamansi juice can also tone and refine the skin when applied topically,” Mills writes further. “The fruit also helps make the skin fairer, since it acts as a mild bleach. The fruit extract can be applied to the affected area safely, without causing burning sensation or irritation.”
