Customer Ratings & Reviews

I initially bought this because my Partners business causes him a lot of mental stress and ups his anxiety levels. When I read that Theanine is a Neurologically Active Amino Acid that is found almost exclusively in green tea which is an excellent antioxidant. The JARROW formula is a food brand, and reading that it promotes relaxation without any drowsiness, it sounded perfect and it has worked! Just found the empty bottle so will repurchase this today!

What I appreciated most was its gentle, yet effective, calming effect. It helped me feel more centered and focused without any noticeable side effects. I found myself better equipped to handle daily challenges with a sense of clarity and composure. The convenience of the capsules made it easy to incorporate into my daily routine, whether at home or on the go. Plus, knowing that it's a naturally occurring compound found in tea leaves gave me peace of mind about its safety and efficacy. Also, it gives me so much energy!

Theanine is incredibly helpful for promoting focus and calm at the same time, but I find that if I take it every day over a period of time, I no longer notice the effects as much. I like to keep it on hand for periods of stress or to help with relaxation. And Jarrow is one of the brands I trust!

Jarrow Formulas' Theanine 200 provides effective support for maintaining focus and reducing stress. Theanine, an amino acid found in green tea, promotes a calm yet alert state of mind without causing drowsiness. Since incorporating this supplement into my routine, I've noticed a noticeable improvement in my ability to concentrate and manage stress. While the effects may vary from person to person, I appreciate the natural approach to enhancing cognitive function that Theanine 200 offers.

It’s much better than just 100 mg for me. Gets me the results that I want. See also my review on the 100 mg product. If you’re on the fence, I recommend it! It can be life-saving in various life circumstances that involve stress, reactivity, pressure. I love this. Due to price per value I switched to the Now foods brand L-theanine product.

Jarrow Formulas Theanine has become my go-to supplement for promoting a calm and focused state of mind. The 200 mg potency per capsule delivers a gentle yet noticeable sense of relaxation without causing drowsiness. I've experienced enhanced mental clarity and a welcome reduction in stress since integrating this into my daily regimen.

If you struggle with stress, anger, and sleep issues you should give Jarrow's Theanine a try. It is a small veggie capsule to be mostly taken on an empty stomach or as directed by your physician. L-theanine is a non-essential amino acid found in higher concentrations in green tea. I take it with my coffee in the mornings and before bedtime. The quality is excellent for the price and the ingredients are gluten-free and non-GMO. The size of the capsule is small.

Theanine has become a game-changer in my daily routine. As someone prone to stress and occasional jitters from caffeine, the subtle calming effect of theanine is a welcome relief. It provides a smooth focus without the drowsiness, making it perfect for a centered and stress-free mindset. Whether sipping on green tea or taking it as a supplement, theanine has earned a permanent spot in my self-care toolkit.

With this high-quality product, I improve my general well-being. The product tastes good and does have not any redundant smell. I don't experience any side effects. This product improves calmness and focus in my mind. And while I am training, I don't feel any effects which would bother me.

Theanine is amazing! I withdrew from antidepressants and started taking theanine. It's been 6 months, and I no longer experience anxiety. I am better able to handle stress, and it's more difficult for me to have another meltdown since I started taking it. One pill is enough for me, but I increase the dosage on days I know will be difficult. There have been many studies on Theanine, and it's considered safe for use even in children
