Today at Examine.com, we bring you a page on adrafinil, a synthetic stimulant. Adrafinil is a precursor to modafinil, which means adrafinil is metabolized into modafinil after supplementation. The two compounds have very similar properties.
In fact, a lot of research on adrafinil stopped after it was discovered that modafinil was a more effective option. Adrafinil takes more time to start exerting its effects (since it has to be metabolized first), which meant the faster-acting modafinil is used to treat disorders like narcolepsy. Modafinil also leaves the body faster, which makes it less likely to interfere with regular sleeping patterns.
Both adrafinil and modafinil are being investigated for their roles as nootropic agents, as they have potential for enhancing memory formation. Both supplements are used to reduce sleepiness and improve alertness. Evidence suggests they may even be more effective than caffeine at improving focus.
Though there is no published evidence to suggest adrafinil is bad for the liver, the producers of adrafinil have issued a warning against prolonged usage. Since adrafinil is metabolized in the liver, adrafinil should not be supplemented for more than six months at a time.
