misleading

The bottle says it is 200 MG 60 capsules. But the servings in the back say it is 200 gm per two capsules so it is only 30 servings. For the price they charge you can find yourself ltheanine that has higher dosage and more servings. Will not buy it again.

Excellent Coffee Antidote

NaturesPlus Pro Suntheanine L-Theanine 200 is an excellent antidote whenever too much coffee has been consumed -- and you get the jitters, or even worse, anxiety about something that otherwise is insignificant. Based on personal experience, many sleepless nights caused by a late night coffee, were made tolerable by the use of L-theanine. The amount of caffeine in drip-brewed coffee is difficult to control, based on the coffee brand, etc. For a coffee drinker, it's important to have on hand L-theanine. Suntheanine is a well-regarded brand of L-theanine, and thus the best choice for an antidote to too much coffee.

Peace of Mind with the Benefits of Suntheanine

“If you’re gonna get L-theanine, make sure it’s Suntheanine. It lasts longer than the regular stuff and this one really helps me feel calm. I usually take 2 caps a day – either during the day when my brain won’t stop racing, in the evening after work, or sometimes right before bed. Feels super safe too. Some people even pair it with caffeine for that calm-but-alert vibe, way better than caffeine alone.”

High quality L-Theanine

I ordered this to be part of a diet supplement regiment. I ordered this particular brand because when I was researching each one on iherb Suntheanine kept coming up as the highest quality form of L-Theanine. I looked a a few including a very expensive “Thorn” supplement version and came back to Nature’s Plus for the quality/brand/price ratio. L-Theanine is the ingredient.

Good

The bottle feels sturdy with a solid seal, and the capsule size is easy to swallow. 60 capsules will last a bit over two months if you take one a day. Quality seems good—they use Suntheanine, which is supposed to be the pure form, and there’s no weird aftertaste or fillers. No noticeable flavor, since it’s a capsule, and it doesn’t upset my stomach. I’ve found it helps me relax without making me sleepy, just a calm focus, which is exactly what I was hoping for.

The best for calm and sleep

It's my routine now. I’m taking it every night and I can sleep like a baby, whole night and next day I'm calm and I have energy to start a day. The capsules has great size. I trust for this brand, I’m buying many products of them, because they have the best quality.

I bought a combination of magnesium and this, L-Theanine, to help with my stress, lack of sleep and for all the neuroprotective properties. I definitely feel quite a change with an overall calmer feeling. The quality of the product goes without requiring mention but being a vegan friendly supplement was the deciding factor. I-Herb is quick to ship as well.
