Contains valuable bitter compounds—perfectly balanced: The bitter compounds contained in Pro Intest belong to the group of phytochemicals. When taken before a meal, they stimulate the digestive organs through a reflex action and can thus help alleviate many of the discomforts that may occur after heavy meals. Pro Intest is therefore the perfect companion for meals.

The recommended daily dose is 3 x 30 drops, preferably diluted with water, juice, or fruit puree, for example, 10 minutes before a meal or after a meal.

Notes:
Store in a cool, dry place away from light.
Keep out of the reach of small children.

Gentian and Wormwood

Pro Intest contains extracts from a total of 13 carefully selected natural herbs. Gentian and wormwood are the most bitter herbs known to date. That is why they are also used in our herbal bitters. Pro Intest’s high-quality bitter drops can help compensate for a deficiency in bitter compounds, which is not uncommon these days.

Prevent Cravings with Bitter Substances

Since bitter substances can speed up digestion, the feeling of fullness may set in sooner, thereby curbing appetite. Because they can also curb cravings for sweets, bitter substances—along with many other measures—can help with weight loss.

“I’ve been working as a naturopath for 15 years, and I’ve been recommending TISSO products for just as long. What continues to impress me time and again is the outstanding quality and the well-thought-out formulation of each product. What’s also worth highlighting is that the products are based on the latest scientific findings and take into account the company’s own studies and observational data.”

FREQUENTLY ASKED QUESTIONS

Pro Intest is generally very well tolerated. It contains only natural ingredients—a traditional alcoholic extract made from 13 herbs—and contains no flavor enhancers, artificial colors, or preservatives. However, individual intolerances to specific plant substances cannot be ruled out. If you have known sensitivities—such as to wormwood, walnut, or papaya leaves—it is recommended that you consult a doctor or naturopath.

Note: This product contains alcohol and is therefore not suitable for everyone. An alcohol-free alternative is our Pro Intest alcohol-free.

The recommended dosage for adults is:
30 drops 3 times a day, preferably diluted with water, juice, or fruit puree. It should ideally be taken about 10 minutes before a meal—alternatively, it can also be taken after a meal.

Do not exceed the recommended daily intake.

For best results, the herbal bitters should be taken regularly with meals—preferably before eating to aid digestion. Please shake well before use, as plant-based ingredients may settle. Due to the bitter taste, we recommend diluting it with a little liquid or fruit puree.

Both products are based on the same herbal extract made from 13 proven plants. The difference lies in the manufacturing process and composition:

Pro Intest contains a classic alcohol-based extract—ideal for anyone who prefers an intense, traditionally made bitter tincture.

Pro Intest alcohol-free is the alternative for anyone who wants to or needs to avoid alcohol. In addition, this version provides zinc, which supports the metabolism of carbohydrates, fats, and proteins.
