Succinic acid is involved in the process of assimilation of oxygen by cells and ensuring cellular respiration, transport of trace elements, protein synthesis, production of new cells of the nervous and immune systems. It is actively used in asthenic conditions, including in the elderly, contributes to the normalization of the lipid profile of the blood (lowering cholesterol), protecting the liver from overload when disposing of various toxic substances coming from food, as well as when taking alcohol.

Succinic acid acts on organs exposed to free radicals and toxins (for example, as a result of excessive amounts of alcohol, certain medications). At the same time, the amount of energy produced during the oxidation of succinic acid is higher than during the oxidation of any other substrate.
The main cause of malfunctions of various body systems is the excessive accumulation of "harmful" free radicals in the body. The main resource of the body's natural protective antioxidant system is succinic acid, which protects cell membranes from oxidative stress, preventing their structure and functions from being disrupted. It is present in every cell of our tissues, is produced in mitochondria and contributes to energy production. A healthy body has enough of the usual amount of succinic acid produced. However, intense physical exertion, smoking, excessive alcohol consumption, taking certain medications, stress, poor nutrition, exposure to ultraviolet radiation from the sun increase its consumption and deplete the reserves of the body, which can result in the development of a number of diseases and premature aging.
Succinic acid is most important for the functioning of the brain and heart - they require the greatest amount of energy and oxygen. Succinic acid is an organic acid that is produced in all cells of the body. It is utilized to form ATP (adenosine triphosphate), a universal energy source for all types of synthesis.
