G.I. plus


Vegan food supplement for the gut and the immune system

G.I. plus was developed in cooperation with doctors and nutritionists. Precious natural plant extracts from frankincense, chamomile and myrrh form its basis. In addition, the innovative, application-specific formulation contains the amino acid L-glutamine as well as biotin to support a healthy intestinal mucous membrane and zinc to promote the immune system. The carefully selected ingredients make G.I. plus a valuable dietary supplement with a focus on the gastrointestinal tract. G.I. plus can be used as a stand-alone intestinal remedy or in combination with regular antibiotic intake.


Frankincense extract

Frankincense, the gum resin of the olibanum tree (Thus album), has a long tradition of being used for medical and traditional religious applications.  It has intensely been studied for its anti-inflammatory properties, such as joint pain and arthritis. Among the most important and biologically active ingredients of incense are boswellic acids in beta configuration.

Myrrh extract

Like Frankincense, myrrh (Commiphora molmol) can also look back on a long tradition. Myrrh is an air-dried rubber resin. Even though the mechanism of action of myrrh has not yet been finally clarified, it is assumed that the ingredients of myrrh can have a contracting effect on the mucous membranes. Myhrre extracts can be used in many ways, for example in dentistry, gastrointestinal complaints or as tinctures.

Camomile extract

Chamomile is a world-famous medicinal and medicinal plant for various complaints. Camomile blossoms are used, which can also have a positive and calming effect on the gastrointestinal tract. Due to the additional anti-inflammatory, antibacterial and antispasmodic properties, chamomile can be used in a wide range of applications.

L-Glutamine belongs to the semi-essential amino acids. This means that our body can basically produce them itself. However, under various conditions such as illness or growth, L-glutamine can become essential and must therefore be supplemented externally. In addition, L-glutamine is one of the most abundant free amino acids in terms of quantity and represents an important substrate source, especially for cells of the gastrointestinal tract.

Zinc is an essential trace element and is important for healthy skin, hair, nails and the immune system. The compound zinc gluconate has a high bioavailability and can therefore be effectively absorbed by the body. Zinc contributes to the normal functioning of the immune system and to the protection of cells against oxidative stress.


Biotin, also known as vitamin B7, belongs to the water-soluble group of B vitamins. Like zinc it contributes to the health of skin and hair as well as to the maintenance of a normal (intestinal) mucous membrane.
