Side Effects of Noni Juice

Noni juice is an increasingly popular beverage that people drink because of its reputation for body detoxification and cleansing, immune system enhancement and energy boosting. Noni fruit comes from the noni plant, a tropical evergreen plant.

Most side effects appear to be related to the detoxification process and are short in duration.

Laxative Effect

In some world regions, noni juice is used as a laxative, so people can expect a certain risk of diarrhea. Decreasing the dosage should alleviate that side effect.

Detox Effects

The most commonly reported side effects are headaches, bad breath, joint pain, acne, fatigue, rashes and foul-smelling urine. These are all common effects of other natural detoxification substances and usually disappear within a week.


People with ongoing gastrointestinal problems related to noni juice should increase the amount of water they drink, or add fresh lemon juice to the noni juice.

Allergic Reactions

Some people appear to have a mild allergic reaction to drinking noni juice, with symptoms of coughing and wheezing.


Two reports of liver disease associated with noni juice have been reported, and a report from the World Journal of Gastroenterology cautions about the potential hepatotoxicity of the juice.
