Cholinergics are preparations whose activity is inevitably combined with acetylcholine – a key neurotransmitter and neuromodulator in the body. They work in various ways: they provide substrates (especially choline) and cofactors necessary for the production of acetylcholine; they stimulate its release from the synapse; modulate the sensitivity of specific receptors; they inhibit acetylcholinesterase, an enzyme responsible for the degradation of acetylcholine.
Acetylcholine is involved in all the important functions of the body. It conditions memory processes, encoding memories, learning, the ability to focus attention. It also affects mental well-being, supports normal sleep, stimulates skeletal muscles. The effect of cholinergics is to raise the level of acetylcholine or to strengthen its activity in the body, leading to a considerable improvement in the psychophysical condition.
Supplements in this category are reputed to be extremely effective nootropic agents. They can significantly improve memory and cognitive functions; they also show neuroprotective effects. In addition, they promote well-being and increase energy levels. They can be successfully used to increase mental performance and strengthen intellectual potential.
