Best L-Theanine Supplement – December, 2019 Reviews & Buyers Guide

There’s no way to sugar coat this: anxiety is a pain. While anxiety can be a normal part of life, excessive anxiety can take a toll on your well-being, physical health, or your quality of life. But thankfully, you may not have to suffer through it unaided—and you may not have to take a prescription medication to reduce your symptoms (which is especially useful if your anxiety is occasional or situational in a way that may make it unlikely for you to get approved for a medication).

Of course, you will need to check in with a licensed medical provider, but you may want to bring up the potential relief from and L-Theanine supplement.

The best L-Theanine supplement may help reduce anxiety by helping you feel more relaxed, restful, and tranquil. This unique amino acid, which is found in green tea, may even help encourage better sleep (and anyone with anxiety knows that insomnia can be a very unfortunate side effect), lower blood pressure, or even help prevent Alzheimer's disease. An L-Theanine supplement may also help improve your alertness and ability to concentrate (I know when I’m anxious, my ability to focus can go right out the window).

Before you decide which L-Theanine supplement amazon offers may be right for you, you’ll want to know these important facts:

1. If you are pregnant or breastfeeding, you’ll want to avoid using an L-Theanine supplement.

2. You may want to speak with your doctor before you begin taking an L-Theanine supplement, since it may interact with or negatively impact some medications.

3. When considering potential L-Theanine side effects, keep in mind that there have not been a lot of long-term studies done on L-Theanine. Your doctor can help you decide if long-term use of an L-Theanine supplement is worth the potential risk.

4. You’ll want to be certain you purchase your L-Theanine from a reputable brand so that you can be confident you’re getting some of high quality.

BulkSupplements Pure L-Theanine Powder

It’s a well-known fact that more and more brands are simply jumping on the “natural health” bandwagon without actually caring about natural ingredients, your health, or the environment. And if you want to support a brand with the kind of commitment and ethics you can believe it, this can be a disheartening thing to realize. But, thankfully, NOW L-Theanine is a brand you can feel good about.

NOW L-Theanine started fifty years ago, with a strong commitment to natural health, and is still going strong on that principle today. In fact, NOW L-Theanine is created by a brand that is still family-owned and operated, so you know exactly who you are supporting and just what they believe in (way more than with some mega-corporations that are faceless and seem to have contradictory missions and goals).

In addition to L-Theanine, NOW L-Theanine features a member of the vitamin B family, Inositol, that is considered essential for the better nervous system and brain health. So when you take NOW L-Theanine, you can feel good both about the company itself as well as the supplement’s ingredients.

Nurtra Champs Focused Energy

Many people love t-theanine not only for its potential ability to help reduce anxiety but also for the way it can work when taken with caffeine. While caffeine can help you feel alert and focused, it can also cause you to feel jittery or too wired, which can in turn even trigger anxiety (it always does in me). But L-Theanine’s calming properties can help you experience the benefits of caffeine without the unpleasant side effects.

Nurtra Champs Focused Energy takes full advantage of that by including not only L-Theanine but caffeine (as well as yerba mate) right in the supplement. This can allow you to possibly have the kind of clear-minded mental focus that you would normally get from caffeine, but without the unpleasant jitters that a cup of Joe can cost you.

And if you aren’t sure that the combo of caffeine and L-Theanine will work well for you, Nurtra Champs Focused Energy has got your back; they offer a full refund if you’re unsatisfied with how Nurtra Champs Focused Energy makes you feel.

Pros and Cons

  • Contains caffeine
  • Lifetime guarantee
  • Includes Yerba Mate
  • May trigger headaches
  • Can cause nausea
