You’re anxious, worried, freaked. You’re upset about (pick one): money, health, work, family, love. Your heart is beating fast, your breathing is shallow and rapid, your mind is imagining doom, and you wish you could just relax…now! Whether you have a full-blown anxiety disorder or are just freaking out, you may not want to try medication—at least not yet.
There are many safe nondrug remedies for anxiety, from mind-body techniques to supplements to calming teas. Some start working right away, while others may help lessen anxiety over time.

You can get that much L-theanine from green tea, but you’ll have to drink many cups—as few as five, as many as 20.
