  • Human Clinical Trials
    TAHITIAN NONI® Juice is the only Noni Juice backed by multiple human clinical trials.
    When Tahitian Noni International (TNI) introduced TAHITIAN NONI® Juice in 1996, TNI became the world’s first noni company. TNI has been the recognized noni leaders from that time until today—no one knows more about noni, period.TNI is the only noni company that controls the entire noni production process, from tree to bottle. They harvest the fruit from the pristine islands of Tahiti, where the soil remains naturally rich and the native Tahitians have used and revered the noni fruit for thousands of years.It’s been helping people for more than a decade. Now ongoing research has revealed even more reasons to drink TAHITIAN NONI® Juice…and more reasons to drink more!

  • TAHITIAN NONI® Juice is Cholesterol-Friendly
    In order to maintain a healthy cardiovascular system, you have to keep your cholesterol under control. In research presented to the American Heart Association, Dr. Anne Hirazumi-Kim indicated that drinking three to four ounces of TAHITIAN NONI® Juice daily helps sustain cholesterol at existing normal levels.

  • TAHITIAN NONI® Juice Supports the Immune System
    Without a variety of daily nutrients, the body’s complex immune system won’t always function properly. Our daily lives are filled with stresses and complications, which can contribute to weakening our immune system. Luckily for us, research shows that drinking TAHITIAN NONI® Juice can help support a healthy immune system. See Research

  • TAHITIAN NONI® Juice Increases Energy
    Today’s hectic lifestyles leave many of us with a lack of physical and mental energy. Almost two decades’ worth of studies indicate that drinking TAHITIAN NONI® Juice consistently can naturally increase both mental and physical energy. See Research

  • TAHITIAN NONI® Juice is a Super-Antioxidant
    Antioxidants are vital to healthy living—they help boost the immune system and fight off harmful free radicals. In laboratory tests, TAHITIAN NONI® Juice has been shown to be rich in natural antioxidants that your body can easily use. See Research

  • TAHITIAN NONI® Juice Supports a Healthy Cardiovascular System
    A healthy heart is essential to overall well-being, and numerous studies have demonstrated noni’s ability to support a healthy cardiovascular system. See Research

  • TAHITIAN NONI® Juice used in Athletics and Sports Recovery
    Numerous reports and personal testimonials from world-class athletes suggest that TAHITIAN NONI® Juice may assist in recovery from sports exertion and discomfort. In addition, TAHITIAN NONI® Juice does not contain any substances banned by the World Anti-Doping Association.See Research

    1. May lower cholesterol and triglycerides in adult smokers

    In this study presented to the American Heart Association, TAHITIAN NONI® Juice was given to 106 adult smokers ranging from 20-60 years in age. After one month of drinking the juice, researchers found that the average cholesterol level of these TAHITIAN NONI® Juice drinkers fell from 235.2 to 190.2. Another group which received a placebo experienced no significant change.

    2. A complete review of TAHITIAN NONI® Juice

    Noni has been used by Tahitians for thousands of years, but only recently has it become a popular item for mainstream consumers. This popularity has raised several questions about the noni fruit, and in this study Tahitian Noni scientists conduct several tests to verify that the noni fruit and TAHITIAN NONI Juice are, in fact, safe for consumption.
