Interaction Details
Modafinil is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Beet Overview
Beetroot is a type of root vegetable belonging to the Chenopodiaceae family. It is commonly consumed as a food and utilized as a dietary supplement. Beetroot supplements are purported to have a number of potential health benefits, including lowering blood pressure by increasing the production of nitric oxide, improving exercise performance, and reducing inflammation.
Dietary supplements containing beetroot are generally in powdered form, and are sometimes standardized by their nitrate content.
Modafinil Overview
-
Modafinil is used to treat excessive sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts). Modafinil is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore doesn't get enough restful sleep). Modafinil is in a class of medications called wakefulness promoting agents. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.
