Many Americans struggle with getting a restful night’s sleep. In fact, statistics show that 25 percent of Americans experience acute insomnia each year. Many sufferers have turned to alternative methods for relief.

One powerful method is the use of a unique chemical called L-theanine. L-theanine is a potent amino acid, most commonly found in tea leaves, and is known to improve mood, reduce occasional stress and anxiety, and promote total-body wellness. It may also help the body's immune system respond to infection by boosting the disease-fighting capacity of gamma delta T cells.

One major benefit of this phytochemical is its ability to support restful sleep. Research shows that L-theanine promotes relaxation, and can also help consumers ease stress and unwind.

Researchers in one study found that L-theanine reduced the resting heart rate in human participants and also greatly improved sleep in both humans and animals. Similarly, another study found that human participants who regularly consumed L-theanine for six weeks experienced longer, more restful sleep.

If you’re interested in taking advantage of the benefits of L-theanine, it may be time to think about incorporating this nutrient into your diet.
