Stimulants, in general, work by increasing the levels of neurotransmitters such as dopamine and norepinephrine in the brain. These chemicals play a critical role in alertness, attention, and motivation. Many OTC stimulants are formulated with ingredients that naturally support cognitive performance, such as caffeine, L-theanine, and herbal extracts. While these substances can provide noticeable benefits, their efficacy depends on factors such as dosage, individual tolerance, and the specific formulation of the supplement.
Most Effective OTC Stimulants for Mental and Physical Performance
Several over-the-counter stimulants have been shown to be highly effective in enhancing mental clarity and energy. The most popular choices include caffeine, which is the most widely used stimulant worldwide, and other compounds that complement its effects.
Caffeine, found in coffee, tea, and various energy supplements, is a well-researched stimulant known for its ability to improve alertness and cognitive function.
