The ingredients, their exact dosage, and interesting information.

Guayusa extract

110 mg caffeine from 500 mg Guayusa extract / 30 ml concentrate

Guayusa (Ilex guayusa) is a holly plant from the upper Amazon region, closely related to Mate. Its center is in the rainforests of Ecuador, Napo Province, at an altitude of 200 to 2,000 meters. Archaeological finds prove its use for over 1,000 years: In Bolivia, researchers found dried Guayusa leaves in a tomb far outside its distribution area, evidence of early long-distance trade. Among the Kichwa, the tree is called "Night Watchman"; the leaves are boiled in a clay pot in the early morning hours. It is still cultivated in chakras, traditional forest gardens.

Bluenesse®

93 mg / 30 ml concentrate

Bluenesse® is a standardized special extract from lemon balm (Melissa officinalis), a Lamiaceae plant from the Eastern Mediterranean and the Near East. Its name comes from the Greek word for honeybee. Charlemagne ordered its cultivation in every imperial estate in 812 in the Capitulare de villis — since then, lemon balm has been an integral part of European gardens. Bluenesse® itself was developed in the 2000s at Vital Solutions (Langenfeld) under Dr. Sybille Buchwald-Werner: a specially selected cultivar, grown in Europe, extracted with water. Patented since 2009 (WO2009/056208).

Citicoline

250 mg / 30 ml concentrate

Citicoline (Cytidine-5'-diphosphocholine, or CDP-Choline for short) is not a plant extract, but an endogenous mononucleotide found in the cells of humans, animals, and microorganisms. Its history began in 1956: Biochemist Eugene P. Kennedy, together with his doctoral student Samuel B. Weiss at the University of Chicago, described the Kennedy pathway named after him. To this day, it remains one of the cornerstones of cell biochemistry. Since the 2000s, citicoline has been obtained through biotechnological fermentation. In the EU, it has been approved as Novel Food since July 1, 2014 (Implementing Decision 2014/423/EU, now VO (EU) 2017/2470).

Rhodiola rosea

200 mg / 30 ml concentrate

Rhodiola rosea (rose root) belongs to the Crassulaceae family and owes its name to the rose scent of its freshly cut rhizome. It grows on barren rock crevices in the Arctic, Siberia, Scandinavia, Iceland, Greenland, and in the high mountains of Central Asia up to 5,000 meters. In Northern Europe, the Sámi and Vikings used it for centuries; in China, it is known as Hong Jing Tian. From the second half of the 20th century, Rhodiola was the subject of a state-sponsored Soviet research program. The extract is standardized to at least 3% rosavins, a group of compounds found only in this species.

L-Tyrosine

360 mg / 30 ml Concentrate

L-Tyrosine is not a plant extract but a proteinogenic aromatic amino acid (chemically 4-hydroxyphenylalanine) and a component of the proteins of all living beings. It was discovered in 1846 by Justus von Liebig, who isolated the substance during the alkaline decomposition of the milk protein casein from old cheese and named it after the Ancient Greek tyros (cheese). The structure was described by Warren de la Rue in 1848 and confirmed in 1883 by Emil Erlenmeyer and Lipp through synthesis. Today, L-tyrosine is obtained either through the hydrolysis of plant proteins such as corn, wheat, or soy protein, or through biotechnological fermentation.

Eleuthero

400 mg / 30 ml Concentrate


Eleuthero (Eleutherococcus senticosus) is a thorny shrub belonging to the Araliaceae family, related to true ginseng and ivy. It grows in the Taiga of Northeast Asia, Eastern Siberia, Northeast China, Korea, and Hokkaido at temperatures as low as -40 °C. In China, the root has been known as Ci Wu Jia for over 2,000 years. Its modern history began in the 1950s: The Soviet pharmacologist Israel Brekhman systematically studied the plant and published his findings in 1958; from 1964, the extract was industrially produced in Russia.

Panax Ginseng

250 mg / 30 ml concentrate


Panax ginseng belongs to the Araliaceae family and grows in the shady mountain forests of East Asia, Manchuria, the Korean Peninsula and the Russian Far East. In Chinese, the root is called Renshen, "human root," due to its human-like branched shape. It was first mentioned in writing in the Shennong Ben Cao Jing during the Han Dynasty (206 BC to 220 AD). For a long time, it was reserved for the imperial family; wars were fought over the ginseng forests of Manchuria. It came to Europe in the 17th century through Jesuit missionaries. Carl Anton von Meyer gave it its botanical name in 1842. Cultivated ginseng grows for about six years.
