The following is a summary of studies on Stevia, which is one of the ingridients in Razitonit Tea.
Stevia leaves for sweetening and weight loss - findings from randomized controlled trials
The stevia plant originates in the rainforests of South America and is known as the "sweet medicinal plant of Paraguay". Stevia leaves are sweet and free of calories and sugar. Therefore, people with diabetes increasingly use stevia for sweetening. Moreover, the use of natural stevia leaves has no side effects, in contrast to the side effects that may exist in various artificial sweeteners.
Because of these properties, many people around the world choose to sweeten their drinks and food using stevia leaves instead of sugar in order to lose weight. But are stevia leaves really able to help with weight loss?
A recent study published in the journal Nutrients examined this question using a randomized controlled trial. The researchers recruited 28 patients and randomly divided them into two groups. The treatment group received stevia leaf extract on a daily basis, while the control group did not receive the treatment. The researchers followed both groups for 12 weeks. At the end of the period, the researchers found a statistically significant difference between the two groups: the patients in the control group gained weight, while the patients in the treatment group who consumed the stevia leaves on a daily basis maintained their weight. Since this is a randomized controlled trial, it can be determined with a particularly high level of confidence that the lower weight among the subjects in the treatment group is a direct result of the consumption of stevia leaves. The researchers concluded that stevia helps maintain weight.
Another study, published in The Journal of Nutrition in 2020, examined how consuming a beverage sweetened with stevia, compared to other sweeteners based on glucose or sucrose, affects appetite and satiety. The researchers randomly assigned subjects to receive various beverages before their lunch without knowing what type of beverage they were consuming. In order to measure the subjects' appetite, the researchers asked the subjects to rate their appetite on a scale ranging from 0 to 100. The results of the experiment showed that the consumption of the beverage sweetened with stevia caused a decrease in short-term appetite and a feeling of satiety compared to the consumption of beverages sweetened with sugar.
The findings from these two experiments provide strong and clear evidence that the stevia plant not only does not contain calories, but also contributes to a feeling of satiety and helps with weight loss.

Obesity and Overweight across the World
The western world suffers today from problems of overweight that have reached epidemic proportions, as well as deficient nutrition deriving from the prevalence of processed foods containing chemicals, preservatives and other flavoring and coloring materials.
In 1975, 20% of the world population has suffered from overweight or obesity. Today, the figure is about 40% (with 650 million who suffer from obesity around the world). Across the globe, obesity has nearly tripled since 1975.
In western countries such as the United States and Great Britain, more than 2/3 of the population suffer from either overweight or obesity.
Obesity increases the chances of diseases such as diabetes, heart disease and vascular disease.
In Israel, youths aged 13-15 are ranked in third place after the United States and Greece.
As a response to this world obesity epidemic, the Israeli company Nufar Natural Products has developed a herbal tea called “Razitonit” Tea.
Razitionit Tea contains: Stevia, medicinal dandelion, fennel, Gymnema Sylvestris, green tea, olive leaves, medicinal sage, eucalyptus and mint.
These medicinal herbs are known to stimulate a feeling of satiaty and reduce cravings.
How does it work?
The medicinal herbs in this new tea help the surplus sugars and carbohydrates in the blood enter the cells, which nourish them and give them the energy our bodies need.
When the body’s cells have been nourished with the food and energy they need, they send “full” signals to the brain, which stops the constant feeling of hunger. As a result of this, we eat smaller quantities and we gradually lose weight.
Razitonit Tea also contains the herb Stevia and thus is naturally sweet and palatable without any sugar or calories.
Another important herb in Razitionit Tea is Dandelion (Taraxacum) which improves the digestion process -- another factor that contributes to weight reduction.
