Your aunt swears by her morning glass of noni juice. Your colleague says she read it can hurt your liver. Your pharmacist looked at you sideways when you asked about it. So who's right? The honest answer is that noni juice is enjoyed daily by many people, but it isn't right for everyone. At Noni Nectar we'd rather you drink Tahitian Noni Juice with your eyes open, so this guide covers the real noni juice side effects, who should avoid it, and how to drink it sensibly.
Is Noni Juice Safe?
For most healthy adults, small daily servings of noni juice are generally well tolerated. Safety research on noni mostly covers use for up to around three months, and regulators such as the European Food Safety Authority have reviewed noni juice. The main cautions relate to the liver, potassium, pregnancy and certain medications. If none of those apply to you, noni juice is simply a food product with a very distinctive taste.
Common Noni Juice Side Effects
Digestive upset
Some people notice mild stomach discomfort or looser bowel movements, especially when they start with a large serve. Start small, around 30ml, and see how you feel.
The taste
Noni has a strong, fermented, slightly bitter flavour (the fruit is nicknamed "cheese fruit"). It's not harmful, but it's the number one reason people give up. Our guide on how to drink noni juice has tips to make it easier.
Less Common but Important: Liver, Kidneys and Potassium
Liver
A small number of case reports have linked noni products to liver problems. The European Food Safety Authority concluded in 2006 that there wasn't enough evidence to prove noni juice caused them, but later reports suggest some people may be particularly sensitive. Noni fruit contains natural compounds called anthraquinones, which have been studied in this context. If you have liver disease, avoid noni. If you notice yellowing skin or eyes, dark urine, unusual tiredness or abdominal pain, stop drinking it and see your doctor.
Potassium and kidneys
Noni juice is relatively high in potassium. That's fine for most people, but if you have kidney disease or are on a potassium-restricted diet, avoid noni juice unless your doctor says otherwise.
