Incorporating a variety of fruits into your weekly diet ensures you achieve sufficient vitamin C levels.
Vitamin C is crucial for immune health and function. Since fruits are particularly rich in vitamin C, knowing which ones pack the highest amounts enables you to modify your eating habits to align with your health goals.
1. Acerola Cherries
Vitamin C: 1,680 milligrams (mg) per 100-gram (g)

Vitamin C: 2,000-3,000 mg per 100 g
Camu camu is a small, tangy berry found in the Amazon rainforest. Both the skin and flesh are rich in vitamin C. However, it is rarely found fresh in the U.S. Instead, look for it in powdered or capsule forms.
3. Guava
Vitamin C: 228 mg per 100 g

6. Strawberries
Vitamin C: 60 mg per 100 g
Strawberries are widely available and versatile. Beyond being a rich source of vitamin C, they provide fiber, which is great for gut health. Their low glycemic index means they won’t cause rapid spikes in blood sugar.

How Vitamin C Supports Your Immune Health
Vitamin C serves as an antioxidant, shielding cells from damage that could lead to inflammation and illness. Additionally, it enhances iron absorption from plant-based foods while supporting the development and maintenance of the body. Insufficient vitamin C levels can weaken immune response and raise the risk of infections.
Since vitamin C is water-soluble and not stored in the body, daily consumption through diet is essential.
How Much Vitamin C Do You Need?
The recommended daily allowance of vitamin C for adults over 19 years is 75 milligrams (mg) for women and 90 mg for men. It is best to avoid excessive consumption, as it may result in changes to DNA makeup.
Most individuals can satisfy their daily nutritional requirements through a balanced diet.
Can Fruit Provide Too Much Vitamin C?
It’s unlikely to ingest excessive vitamin C from fruit alone, as the body naturally eliminates excess amounts through urine. Regular fruits do not contain the high doses found in some supplements. Most individuals can enjoy multiple servings of vitamin C-rich fruits daily without negative effects.
