What are Rhodiola rosea and succinic acid doing in the formula?

Rhodiola rosea is a plant traditionally used during periods of increased mental and physical demands. In herbal medicine, it is classed as an adaptogen: such components are thought to help the body cope more easily with stress factors — whether a deadline, an exam session or prolonged concentration on a difficult task. It is important to understand that it is not a stimulant in the usual sense: rhodiola does not give a sudden energy boost like caffeine, but rather supports resilience to strain.

Succinic acid is a substance involved in cellular energy metabolism. It occurs naturally in the body and is part of the energy-producing cycle in cells. In the kissel, it complements the action of niacin, which is also linked to energy processes.

Together, these components make the product more specifically geared towards periods of mental fatigue, rather than simply making up for a vitamin deficiency. Nevertheless, it is a food supplement, not a medicine, and its effect varies from person to person.
