Nicotine is a nicotinic acetylcholine receptor (nAChR) agonist known for its cognitive-enhancing effects. Its relevance to healthspan is speculative, based on preclinical evidence suggesting it may offer neuroprotection against diseases like Parkinson's and Alzheimer's by reducing neuroinflammation and promoting cell survival. However, these potential benefits must be weighed against its significant addictive potential and cardiovascular risks.
Verdict
High-risk cognitive tool with unproven benefits for overall healthspan.
