Best form of theanine

This is a favorite in our household. Suntheanine is also the best absorbed form of theanine as well. Good price compared to others. Helpful for anxiety and insomnia.

Smooths out racing thoughts and cortisol spikes

L-theanine really is like “safe nicotine without the sketchy baggage.”Both sharpen your mind without putting you to sleep.Both reduce mental noise and help you feel “in the zone.”But unlike nicotine, theanine doesn’t come with dependency, vascular stress, or a dopamine crash.Nicotine lights you up like a firecracker—and then drops you off a cliff.L-theanine is like that cool friend who just brings peace and clarity without causing drama.Take Doctor's Best L-theanine with Doctor's Best magnesium glycinate for best overall results.

Great supplement

Suntheanine, so far, has been a really great supplement to have handy. I have been using it regularly for 3-4 months as of now.The effects: While you may not completely stop thinking anxiously, I find the amount of time spent worrying is greatly reduced. Usually as soon as an anxious thought crosses my mind, it's dropped within 10 seconds, and that's that. Obviously this can have a major effect, especially if you tend to overthink things. Your mind is calmer, depending on how calm or otherwise you were in the first place. Other people report benefits for focus and mental clarity too, and some people also report some sedation at higher doses.The risks: I have had no side effects while using this, and I'm pretty sure many others can say the same. Suntheanine is infamous for being safe at high doses. I have taken up to 600mg (four capsules) at once and 1050mg (seven capsules) a day without any negative effects I can definitely attribute to the suntheanine. That's not to say there definitely isn't any, but you're pretty safe with this one.The dose: The bottle suggests 1 capsule (150 mg) a day away from food. And for a lot of people, that would probably be okay. However, you are not strictly limited to this, and people with anxiety disorders can derive a lot more benefit from taking more than one. I have been told that I could take up to 1200mg a day (eight capsules) if I need to, and that larger doses in some people induces some degree of sedation (and even if it doesn't, the stress relief is still a good thing to have right before bed). I typically take one in the morning, one in the afternoon, and one or more just before I go to bed (I also take one in the middle of the night if I can't go to sleep, and I find it tends to relieve symptoms of not sleeping, which in my case, are worse and probably more anxiety-based). Lately I've been taking 600mg (four capsules) at night in response to insomnia - I can't yet conclude that this helps more since I've only done it three times. But in the beginning, one capsule was a fantastic way to end the day - it felt like all the stress of the day just vanished.The drawback of having 1200mg a day is... you'll run out of this in less than two weeks. So I prefer to keep my consumption as low as possible without ignoring this in times of high stress. My average use for right now still cleans out a bottle within 1 month (it IS important to note, however, that I am currently attempting to drop other anxiety meds, so of course I am subject to some extra stress during this time, and the fact that I use this a lot definitely does not mean that you'll have to as well).Another big plus over anxiety medication is you can simply take this as needed, not at set times every day. No withdrawal, no addiction, nothing like that. My psychiatrist has told me, however, that there are long-term benefits to using this. I haven't been able to verify that (actually, she's the only person I've heard that from, I've never read that online), but if you want to attempt to benefit from that, taking at least one a day as instructed is recommended.In general, I am very pleased with this safe and generally effective alternative to potentially risky prescription medications, and hopefully soon this is the only thing I'll be taking for anxiety.

Excellent Nervous System Support

This helps calm and regulate. I’ve been struggling with 3am cortisol wake ups and taking this before bed has helped lessen these symptoms. I take it during the day too if it’s been an especially stressful day. It doesn’t make you drowsy just calm and grounded. This is wonderful nervous system support.

Natural alternative to anxiety medication

This is such a great natural alternative to anxiety medication. It takes the edge off of stress caused by everyday living. It helps you to go about your day without a lot of the worries associated with our daily lives. I like taking it along with Calms Forte by Hylands.. Taken together definitely calm you without making you sleepy. I always have these two products on hand. After I stopped taking anxiety meds from the doctor I went through withdrawal and these two products were a God send for the side effects the chemical withdrawals I was going through due to Klonopin and Xanax. I really don't know what I would've done without them. A Naturopath recommended them to help with withdrawal and then to help with any anxiety I may have in the future. Awesome product. Helped me immediately. Here is some more helpful information about Suntheanine. I found Doctors Best to work the best, as I have tried other brands.Mental AlertnessClinical trials suggest that an amount of between 50 to 200 mg of Suntheanine stimulates alpha waves (brain activity), which are identified with a calm but alert mental state. Because Suntheanine is absorbed through the large intestine and transported directly to the brain, it stimulates alpha brain waves, which are "emitted" once we have finished an activity and have stopped to rest. Suntheanine encourages the activity of neurotransmitters, which help regulate attention, learning, mood, memory, body temperature, appetite and sleep. All of these are enhanced by the presence of Suntheanine in our bodies. And the substance also may heighten our mental acuity and support our immune system.Stress ReliefSuntheanine is believed to promote stress relief while providing calm and relaxation similar to deep meditation. A completely natural substance, Suntheanine does not produce the undesirable side effects produced by synthetic drugs such as fatigue and drowsiness.: Suntheanine Benefits | eHow.com [...]

You need a full 8-10 hours!

Honestly, if you’re taking this for sleep, you really do need a solid 8–10 hours. I’m guilty of not always doing that, and it definitely catches up with me. If you only get 5-6 hours, don’t expect to just pop up and function like normal. This stuff will have you moving in slow motion. And the next day, even when I think I can squeeze in a nap to make up for it, it still has me feeling like I’m stuck in a fog and at the same time, unable to actually fall asleep.
