Are you looking for an energy booster without negative side effects like anxiety, agitation, and insomnia? Consider adding Adrafinil to your nootropic regimen.


Lafon Labs developed Adrafinil in the 1970s and it quickly became widely used in many European countries to improve wakefulness and for conditions that negatively impact the ability to stay awake. Now Adrafinil is more commonly recognized for its use as a mild stimulant; however, it does not function like your typical energy booster. Rather than causing hyperactivity, Adrafinil helps your body fight fatigue. It is much gentler than standard stimulants as it lacks most of the common side effects [2].

Adrafinil and Athletic Performance

Some athletes substitute a preworkout powder with adrafinil because of its stimulating effects. Using adrafinil one to two times weekly instead of a preworkout powder is an excellent way to cycle. Cycling is necessary with stimulants as the body will otherwise build a tolerance to them, meaning they lose their effectiveness.

Adrafinil vs Modafinil

Adrafinil is also a prodrug for Modafinil, meaning that it leads to increased concentrations of Modafinil in your body.

Adrafinil and Modafinil are similar compounds both created for battling fatigue [3]. Both nootropics have cognitive benefits including increased focus, memory retention, and mental and physical energy. Though they are similar, modafinil cannot be purchased without a prescription.

Adrafinil Benefits and Experiences

Aside from enhancing energy, Adrafinil has also been shown to improve cognitive function through an increase in mental focus, concentration, and memory. The beauty of Adrafinil’s effects is that it is able to fight off fatigue without the negative jittery effects common to most stimulants. Quiet and reserved users have also reported feeling more open and talkative when taking Adrafinil [3].

Adrafinil’s effects might not be immediately noticeable, as they typically build subtly over a period of several days to a few months [2]. This is because Adrafinil selectively stimulates l-adrenergic receptors in the brain. Other stimulants affect a wide range of receptors in the brain leading to possible over stimulation. This is likely why Adrafinil typically has fewer negative side effects [2].

Adrafinil Dosage

The recommended dosage is one scant 1/8tsp scoop (300mg) once daily as needed.

Adrafinil Side Effects

Since Adrafinil is metabolized by the liver, you may wish to use milk thistle to help minimize the impact on your liver from use.
