Galantamine is an alkaloid originally derived from the bulbs and flowers of certain plants (such as Galanthus and Narcissus species). Its use in supporting or treating memory and brain function is scientifically validated, particularly for mild to moderate Alzheimer's disease. Galantamine acts as a reversible, competitive inhibitor of acetylcholinesterase, an enzyme responsible for breaking down acetylcholine in the brain. By inhibiting this enzyme, galantamine increases acetylcholine levels, thereby enhancing cholinergic neurotransmission, which is often deficient in Alzheimer’s disease and other dementias.

Numerous randomized, double-blind, placebo-controlled clinical trials have demonstrated that galantamine can modestly improve cognitive function, activities of daily living, and global clinical status in patients with mild to moderate Alzheimer’s disease. These findings have led to its approval by regulatory agencies (such as the FDA and EMA) for this indication. The evidence for use in other types of memory impairment (such as mild cognitive impairment or non-Alzheimer’s dementias) is less robust, with studies showing mixed results.

Galantamine’s efficacy is not based on tradition or anecdotal evidence but is grounded in modern pharmacological research and clinical trials. It is not considered a cure, but it may help slow the progression of cognitive symptoms in eligible patients. Adverse effects are primarily cholinergic (nausea, vomiting, diarrhea), and it should be used under medical supervision.
