Sulbutiamine – essential information
Sulbutiamine is a synthetic compound consisting of two thiamine molecules – vitamin B1. It was discovered by Japanese scientists with the aim of finding a method to increase the absorption of this vitamin. The discussed compound is characterized by excellent solubility in fats, allowing it to quickly pass from the blood into the brain. Unlike vitamin B1, sulbutiamine is excreted more slowly from the body.
The characteristics of sulbutiamine
Sulbutiamine possesses nootropic properties, which means that it is primarily used to stimulate metabolism within the central nervous system. As a result, it can activate various mental processes, alleviate conditions commonly perceived as abnormalities, and improve the functioning of the nervous system, which is geared towards managing the rest of the body. Thanks to increased brain energy and improved cognitive functions, sulbutiamine is effectively used in the treatment of anxiety and depressive states and reduces feelings of shyness and discomfort. It can even be used in therapy for psychological sexual disorders. Additionally, sulbutiamine increases the number of dopamine receptors in the brain, responsible for experiencing pleasure, and influences focus and self-control. Enhancing brain circulation brings a range of benefits for the entire body, such as increased energy, endurance growth, reduced recovery time, increased tolerance for physical exertion, improved blood flow, and optimization of the body's physiological processes. Therefore, sulbutiamine can be effectively utilized by athletes to improve performance and maintain homeostasis in the body.
Daily dosage recommendation
The recommended amount of sulbutiamine, a derivative of vitamin B1, to be taken daily is approximately 400 mg. Generally, supplementation with this substance is safe and the human body tolerates it well. However, it is crucial to remember that incorrect use of sulbutiamine may result in unwanted side effects. These unpleasant symptoms include eczema and rashes, mood swings, and sleep problems. It is always advisable to consult with a doctor or pharmacist before starting sulbutiamine intake and inform them of the goals one wishes to achieve with this product. This way, unpleasant surprises due to lack of knowledge can be avoided.
