Top 10 Natural Sources of Vitamin C: Powerful Foods to Boost Immunity and Overall Health
Vitamin C, or chemically termed as ‘ascorbic acid‘, is one of the most important nutrients required for maintaining strong immunity and overall well-being. Because the human body cannot produce or store this water-soluble vitamin, it must be obtained through diet on a regular basis.
Vitamin C plays a central role in collagen production, supports the body’s defense system, protects cells from any kind of stress, and enhances the iron absorption from plant-based foods. These combined benefits make it essential for healthy skin, efficient metabolism, heart health, and general life functioning.
While citrus fruits often take the spotlight, many other foods contain far higher concentrations of vitamin C. Below are ten great natural sources of this important nutrient, ranging from exotic superfruits to everyday vegetables.
1. Kakadu Plum
The Kakadu plum, a native to Australia, is recognized globally as the most potent natural source of vitamin C. With an extraordinary concentration of about 2900 mg per 100 g, it contains more than 50 times the vitamin C found in oranges.
- This powerful fruit is available fresh, in powdered form, or as a supplement.
- Its exceptionally high nutrient density makes it an outstanding choice for individuals looking to increase their daily vitamin C intake.
2. Acerola Cherry
Acerola cherry is another nutrient-rich fruit renowned for its high vitamin C content. Providing approximately 1500–1600 mg per 100 g, it stands amongst the most concentrated natural sources available.
