Prebiotics and probiotics
Mayo Clinic says that high-fiber foods or prebiotics, which healthy gut bacteria love, plus probiotics found in various fermented foods, fruits and vegetables would improve both your gut and mental health.  Probiotic supplements also are good sources, but make sure to consult your doctor to find out which would work best for you as not all supplements are created equal.
Self-care and decompress
Stress and anxiety release stress hormones in the body called cortisol that serves as the body’s flight or fight mechanism. This affects how we react mentally and emotionally that could send us through a downward spiral. So 2020 right?
Well the best we could do for ourselves is a little bit of self-care here and there. Self-care and allowing our body to decompress can help ease mental fatigue and brain fog. Perhaps easier said than done but try your best to take your mind off that thing (or things) causing you stress. Meditate, read a book, go out (provided it’s COVID-safe), take a walk in the park, get some nice warm sun. Even in the middle of a busy schedule, squeeze a few minutes to do some breathing exercises or walk around the block, as your brain will surely thank you for it. Just take this 2018 study, the results of which say that even 10 minutes of mindfulness meditation every day could improve your brain functions. 
Better yet, exercise! Movements go a long way and Harvard Health tells us that “the benefits of exercise come directly from its ability to reduce insulin resistance, reduce inflammation, and stimulate the release of growth factors—chemicals in the brain that affect the health of brain cells, the growth of new blood vessels in the brain, and even the abundance and survival of new brain cells."  Add to that a January 2020 study showing how exercise can improve thinking among young people.  So squeeze in some regular yoga and brisk walking into your lifestyle.

One of them is being more alert, attentive and laser-focused.

Livestrong cites a 2009 study from “Cognitive Science” which validates that caffeine “can improve your mental faculties and alleviate fatigue.” 
The same article, however, warns about going overboard with caffeine. Having one too many cups of joe in a day can be counter-productive, and can cause brain fog:
As you go up with a caffeine boost, so you must come down. If you are prone to ingesting high amounts of caffeine, more than 500 mg a day, brain fog can set in. Insomnia, irritability, poor concentration, anxiety and restlessness are a few of the consequences of heavy caffeine use. These effects can occur hours after your last dose and may prompt you to consume more caffeine to counter the effects. However, the cause is not the cure in this case, and you may want to consider weening yourself off of high-dose use.
Erectile dysfunction. In combination, those are two of the ugliest words known to man. But can caffeine help you get it up?
Science hasn't found the definitive answer to this question, but one study concluded that fewer men who consume caffeine have problems performing. The study said:
Caffeine intake reduced the odds of prevalent ED, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day). This reduction was also observed among overweight/obese and hypertensive, but not among diabetic men. Yet, these associations are warranted to be investigated in prospective studies
