Just as good as the more expensive theanine

In a world where patents such as suntheanine are touted as the only maximally effective choice, I can gratefully vouch for more affordable alternatives such as this theanine. Don't get wrong, Suntheanine has been great, but this product is just as calming and anxiolytic. As a student, theanine has also been great for calm focus! Thanks iherb!

It is health that is real wealth and not pieces of gold and silver (Gandhi)

L-theanine is one of those lesser-known supplements that I love to tell people about. Used on n empty stomach, theanine produces a subtle feeling of calm while not impairing physical or mental processes. In fact, people who use l-theanine tend to perform BETTER on tests, as it aids concentration. When taking a long drive, for instance, l-theanine would be very helpful, especially when paired with caffeine. When used with magnesium, theanine produces a relaxed feeling that is helpful when getting ready for bed. Note: it does NOT make one sleepy; it makes one relaxed. I use theanine with magnesium l-threonate about 30 minutes before going to bed. I then take melatonin as I'm climbing in, and I sleep like a baby.

Great

L-theanine is a unique supplement. It is an amino acid and most find they can use it night or day. Great stacked with coffee for no jittery yet focused. Can calm histamine in the body too. I started using it when I was stressed and normal herbs weren’t enough. Once I added this everything changed.

NutraLife, L-Theanine

The quality of the ingredient package benefits for my sleeping aid combination of L-Theanine & Gaba to terminate our brain activity to promote better quality sleep n enhance the energy for the very next day routine, especially training to promote muscle growth as L-Theanine is protein base, good for diet as don't have to intake so much protein, not much on taste as it's in small size capsules.

I've been using these L-Theanine capsules for about a month now to take the edge off my work anxiety. I was skeptical, but I genuinely feel a noticeable sense of calm about an hour after taking one. It doesn't make me drowsy, just helps quiet the constant mental chatter. This has become an essential part of my daily routine.

For focus and relaxation

It supports relaxation without causing drowsiness: Theanine has been shown to increase alpha brain-wave activity (which is associated with a calm but alert state).  May help with stress, anxiety and promote mental calm. May improve sleep quality (not necessarily make you sleepy, but help you relax and fall asleep easier) and enhance focus/attention when used appropriately. If you take it together with caffeine, effects may change (for better or worse) depending on your sensitivity. Basically good ingredients, nice packaging and good quality.

I like it

I’ve been taking NutraLife L-Theanine for a little while now, and I can really notice the difference in how I handle stress. I’m usually the type who gets restless at night, my mind running a mile a minute, but this supplement helps me feel calmer without making me groggy. I can still focus on work and daily tasks, but I’m not as tense as before. The capsules are easy to swallow, and I appreciate that the dosage is already at 200 mg, so I only need one. It also came safely and in good packaging, which is something I always pay attention to since I’ve had a few bad experiences with damaged bottles from other brands. Overall, this has become part of my daily routine, and I can’t recommend it enough if you’re looking for something natural to support relaxation and mental clarity.

Calm Focus and Stress Relief

This L-Theanine works really well for promoting relaxation while keeping the mind clear and focused. It helps reduce daily stress without any drowsiness, making it useful both during work and in the evening. The 200 mg strength feels effective, and NutraLife delivers good, consistent quality. A great supplement for balance and calm.

Can recommend

Very happy with it! The size is perfect, it has no taste and the quality is good with this brand. I feel the benefits in combination with intermittent fasting. Uplifted mood, calmer and less stressed. I take 2 a day, one on empty stomach in the morning and the other one end of afternoon.
