The nutritional content of noni juice varies widely.
One study analyzed 177 different brands of noni juice and found significant nutritional variability among them (2Trusted Source).
This is because noni juice is often mixed with other fruit juices or added sweeteners to mask its bitter taste and foul odor.
That said, Tahitian Noni Juice — produced by Morinda, Inc. — is the most popular brand on the market and widely used in studies. It’s comprised of 89% noni fruit and 11% grape and blueberry juice concentrates (3).
The nutrients in 3.5 ounces (100 ml) of Tahitian Noni Juice are (3):

Like most fruit juice, noni juice contains mostly carbs. It’s rich in vitamin C, which is essential for skin and immune health (4Trusted Source).
Additionally, it’s a great source of biotin and folate — B vitamins that play many important roles in your body, including helping convert food into energy (5Trusted Source).
