Tyrosine
(to strengthen alertness & memory, and fight depression & stress)
Probably the best bang for your buck, this gem of a supplement wears several hats. Fighting depression? Check. Need stress relief? Check. Want to feel more alert and have better cognition? Check. Still need more proof? According to the Naval Aerospace Medical Research Laboratory in Pensacola, FL, tyrosine “may prove useful in counteracting performance decrements during episodes of sustained work coupled with sleep loss.” So, work smarter on limited sleep without the stress. Um… Why did I take No-Doz in college? Tyrosine is found in dietary proteins like egg whites, fish, soy, seaweed and spirulina, or it can be taken in capsule form, as L-Tyrosine (with an RDA of 500mg/day).
