We have discussed the health benefits of camu camu in the following section.

Evidence-Based Health Benefits Of Camu Camu

1. Has Antioxidant And Anti-Inflammatory Properties

This Amazonian berry is rich in antioxidants and can also reduce inflammation (3). Antioxidants protect the cells from the harmful action of free radicals. Regular intake of camu camu in specified dosage can help fight inflammation and decrease oxidative stress. However, the bioactives in camu camu responsible for these properties are yet to be clearly established.

2. May Improve Immune Function

Camu camu is rich in vitamin C that is known for its immune-boosting activity. Vitamin C also protects the body against oxidative stress caused by free radicals (4).

3. May Help Maintain Blood Cholesterol Levels

The vitamin C in camu camu can reduce the levels of serum cholesterol and also help maintain blood cholesterol levels (5).

4. May Help With Iron Absorption

The high vitamin C in camu camu facilitates iron absorption. Vitamin C can effectively absorb the iron from a meal (6).

5. May Help Regulate Postprandial Glycemia

Postprandial glycemia is characterized by a quick spike in blood sugar levels after a high-carbohydrate meal. Camu camu juice may be effective in controlling postprandial glycemia (7).

6. May Help Regulate Blood Pressure Levels

The seed coat of camu camu may have anti-hypertensive compounds that may help dilate blood vessels and lower blood pressure (8).

7. May Aid Weight Loss

Camu Camu may aid weight loss by preventing visceral fat deposition and positively altering the gut bacteria (9). However, more research in humans is warranted in this regard.

These are the major benefits of camu camu. But before you go for the fruit, you must be aware of its potential side effects too.

Camu Camu: Potential Side Effects

Almost all natural foods may have a few potential side effects that generally occur due to its overconsumption. Camu camu also, if taken in excess, may cause the following adverse effects.

1. Digestive Problems

The high levels of vitamin C in camu camu may increase the levels of stomach acids and lead to intestinal wall damage, along with other digestive problems. However, research is limited in this regard.

2. Insomnia And Appetite Loss

Some believe camu camu may elevate serotonin levels that may lead to insomnia or a loss of appetite. Serotonin is essential for regulating your mood and appetite. It is a neurotransmitter that tells the brain whether you are happy or hungry.

Although a healthy serotonin level can alleviate depression, improve your mood, and make you feel happier, excess of it may lead to adverse effects like lack of sleep and loss of appetite. However, limited research is available to prove this adverse effect of camu camu.

3. Chronic Diarrhea

Digestive problems usually lead to constipation and bloating or diarrhea. With camu camu, excess vitamin C may lead to counter-reactions and diarrhea (10).
Note that these side effects, though adverse, are rare. But keep in mind not to consume camu camu in excess.


Camu camu is preferably consumed in the form of powder as the fruit has a strong tangy flavor. Five grams of camu camu powder has 682 mg of vitamin C, and covers 760% of the Recommended Dietary Intake (RDI) of vitamin C. The Tolerable Upper Limit (TUL) for vitamin C is 2,000 mg per day and the current recommended dietary allowance (RDA) of vitamin C is 75 mg for women and 90 mg for men. However, these recommendations may slightly vary from one individual to another (11), (12).


Camu camu may possibly interact with few chemotherapy drugs that rely on free radicals. The vitamin C in camu camu may fight the free radicals and interrupt treatment. However, detailed scientific research is not conducted to clearly establish this interaction.

Special Precautions and Warnings

  • Driving: Camu camu is thought to cause dizziness in a few individuals. If you tend to experience the same, avoid driving right after consuming the fruit.
  • Alcohol: The interaction between alcohol and camu camu is not yet established. However, it is advised to limit alcohol consumption while taking the fruit or any associated vitamins or supplements.
