The Lipton Institute of Tea is a dedicated tea research facility owned by consumer goods company Unilever, which also owns the Lipton tea brand. The Institute conducts studies on the mental and physical health benefits of tea. As well as research conducted directly by the Institute, it also funds and coordinates research projects at academic and research institutions around the world.
The Lipton Institute of Tea is headquartered in Sharnbrook in Bedfordshire, UK. A formal tea research base was established here by Unilever in 1967. The Institute also has research centres and regional representatives located in major tea-growing regions (such as India and Kericho, Kenya, where Unilever owns tea plantations) and other key tea-drinking markets (including France, Japan, China, and the USA). The Institute claims as its mission "to promote awareness and understanding of tea, from bush to cup". [1] The Institute also participates in and organises scientific conferences. [2] [3]
Integral to the Institute’s research facilities is its operation of what it claims is the world’s most northerly tea plantation at its UK headquarters. This facility grows representative samples of tea from around the world in a controlled environment. [4] [5]
The Institute invests in clinical trials to support benefit claims and its scientific understanding of the health benefits of tea. Many of the Institute’s findings have resulted in academic publications. [6]
Recent work has focused on theanine and flavonoid antioxidants, both of which occur naturally in tea and are claimed to have health benefits. [7] The Institute has also funded research on heart health and stroke [8] and, in April 2009, published the results of research conducted with the University of L'Aquila, Italy, about tea and cardiovascular health.

A dietary supplement is a manufactured product intended to supplement one's diet by taking a pill, capsule, tablet, powder, or liquid. A supplement can provide nutrients either extracted from food sources or that are synthetic in order to increase the quantity of their consumption. The class of nutrient compounds includes vitamins, minerals, fiber, fatty acids, and amino acids. Dietary supplements can also contain substances that have not been confirmed as being essential to life, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols. Animals can also be a source of supplement ingredients, such as collagen from chickens or fish for example. These are also sold individually and in combination, and may be combined with nutrient ingredients. The European Commission has also established harmonized rules to help insure that food supplements are safe and appropriately labeled.

Although health benefits have been assumed throughout the history of using Camellia sinensis as a common beverage, there is no high-quality evidence that consuming tea confers significant benefits other than possibly increasing alertness, an effect caused by caffeine in the tea leaves. In clinical research conducted over the early 21st century, tea has been studied extensively for its potential to lower the risk of human diseases, but there is no good scientific evidence to indicate that consuming tea affects any disease or improves health.

Jun, or Xun, is a fermented drink similar to kombucha, differing only in that its base ingredients are green tea and honey instead of black tea and cane sugar. Jun is brewed by fermenting green tea with a symbiotic culture of bacteria and yeast (SCOBY). Fruits, sweeteners, spices, and other flavor enhancers are also commonly added to make the taste of the beverage more appealing. Jun is not as popular as kombucha or other similar fermented drinks, so the commercial market for it is much smaller. Because there are not many companies selling it, and the brewing process is rather simple, many consumers of Jun choose to make it themselves. Many health benefits have been credited to Jun and fermented drinks in general, but these are unproven. Any health effects stemming directly from Jun as a whole have not been researched or conclusively substantiated, but some of Jun's main ingredients have been shown to individually have positive effects on the human body. Though Jun bears similarities to other fermented drinks like kombucha, water kefir, and kvass, it has enough differences to be considered a distinct drink.
