Helps with energy and alleviates depression when taken with 5-HTP
I got off antidepressants using 5-HTP and L-Tyrosine in a 1:10 ratio, per recommendation of my naturopath. This was really amazing because when I tried to taper my antidepressants without supplements, I went from feeling good to feeling some of the absolute worst depression I've experienced, and I've struggled with depression most of my life. Once I added 5-HTP and Tyrosine I was able to taper off the antidepressants with minimal side effects. 5-HTP helps the body produce serotonin, while L-Tyrosine helps the body produce dopamine, which somehow balances that out. It's important to take them together because supplementing one in high levels like I am without adding in the other can create an imbalance in your brain chemicals. 5-HTP on it's own has a slightly sedating effect, so it's good to take it at night, but I take part of my dose in the morning with Tyrosine and don't have a problem. Taking the supplements in pill form was getting expensive (much more so than the antidepressants), so I decided to try BulkSupplements, which are significantly cheaper than getting them in capsules. I have no interest in trying to make my own capsules, so I just mix the powers with water and drink it fast while holding my breath. It works! Figuring out the dosage was a little tricky, but here is what I do: In the a.m. (right after I get up) I mix 1/16 tsp (approx. 100 mg) 5-HTP + 1 tsp (approx. 2000 mg) Tyrosine In the p.m. (just before I go to bed) I mix 1/8 tsp (approx. 200 mg) 5-HTP + 1 tsp (approx. 1000 mg) Tyrosine I do the different dosages because Tyrosine is slightly energizing while 5-HTP is slightly sedating. I tried doing the entire dosage of Tyrosine in the morning and the entire dosage of 5-HTP at night and felt very irritable during the day. Tyrosine on it's own can help with energy and focus, but in too high of a dosage or without the balance with 5-HTP it can cause irritability or even a jittery feeling. When I reduced the dosage slightly I noticed a difference in my mood, so I know it's having a significant effect. The Tyrosine powder has a slightly bitter flavor. It's not very pleasant, but I take it so quickly that it doesn't really matter to me. I'm taking a relatively high dosage because, as I said, I'm using them to replace anti-depressants. I'd recommend talking to a naturopath about dosages and what might be right for you, and I definitely recommend taking 5-HTP with a 1:10 ratio of Tyrosine. When I asked my primary care doctor about supplements for depression, she had no idea what I was talking about, and instead put me on anti-depressants. She also recommended tapering antidepressants in a way that was incredibly harmful to me (needless to say she's no longer my doctor), so be wary of primary care doctors when it comes to this sort of thing. General physicians are well trained on a lot of things, but supplements and diet are generally not among them. If you are more of a do-it-yourself-er, then I'd highly recommend the book The Mood Cure by Julie Ross: http://www.amazon.com/Mood-Cure-4-Step-Program-Emotions--Today/dp/0142003646/ref=sr_1_1?s=books&ie=UTF8&qid=1400876462&sr=1-1&keywords=the+mood+cure It details how to figure out what supplements you may need and how much. Overall, this is a high quality and effective supplement.

Precursor and Building Block for your Brain Power!
Here's the scoop, I did the research so you don't have to... This stuff is legit and is helping in heaps! Literally! L-Tyrosine is a powerful aromatic amino acid that is a building block for dopamine, epinephrine, norepinephrine, and thyroid hormones. Tyrosine supplements are nootropics and adaptogens that help with performance during times of stress. Many people find that it helps significantly with fatigue from stress. L-Tyrosine is produced within the body from a variety of dietary sources. Its primary roles are protein synthesis and maintaining healthy brain chemistry by providing the material from which dopamine, epinephrine, and norepinephrine are produced. These three vital neurotransmitters, known as catecholamines, have a profound effect on energy levels, mood, motivation, and cognitive function. Though L-tyrosine doesnโt directly stimulate the production of these neurotransmitters, it does provide a โbufferโ of the raw material the brain needs to produce them, particularly beneficial when stress has depleted their levels. L-Tyrosine also helps regulate the production of certain hormones and is necessary for the creation of the pigment melanin, which is present in skin, hair, and eyes. In addition, L-tyrosine is chemically related to thyroid hormones and may enhance weight loss by suppressing appetite and improving the bodyโs ability to burn fat. Because the body can produce adequate amounts of L-tyrosine, supplementation isnโt essential for basic health. However, studies suggest that taking additional L-tyrosine can have both physical and cognitive benefits, particularly in scenarios that involve physical or environmental stressors. Benefits and Effects There is robust evidence for the effectiveness of L-tyrosine supplementation, particularly regarding cognitive enhancement, mood and motivation improvement, and mitigating the effects of stress on the mind. Some of the most commonly attributed benefits of L-tyrosine include the following: Cognitive Enhancement Under Stress A 2015 review of more than a dozen studies found that tyrosine loading effectively offset working memory and information processing deficits created by environmental stressors such as extreme weather or extreme cognitive demand. The review speculated that this effect might be explained by the fact that tyrosine provides a โbufferโ of raw material from which the brain can produce neurotransmitters, effectively neutralizing the depletion that stress creates. The review concluded that there is evidence that healthy individuals exposed to demanding situational conditions may benefit from supplemental L-tyrosine. A 1999 military study of cadets on a combat training course showed that a week of L-Tyrosine supplementation significantly lowered systolic blood pressure.[2] The participants receiving L-tyrosine also performed better on memory and tracking tasks than those receiving a placebo. Sleep-deprived individuals receiving supplemental L-tyrosine performed significantly better at a variety of cognitive and psychomotor tasks than a similar group which was given placebo in a 1995 study. Working Memory Improvement Under Increased Cognitive Demand A 2013 study investigating the effect of L-tyrosine on adults doing a progressively challenging mental task found that participants who took supplemental tyrosine did better on the more difficult levels of the task but showed little or no improvement on the easier levels. The researchers said the results confirm the concept that L-tyrosine selectively targets cognitive control situations, providing more resources only when more control is needed. Increased Cognitive Flexibility A small 2015 study involving 22 healthy adults showed that supplemental L-tyrosine enhanced cognitive flexibility, the ability to switch between tasks or modalities of thought. This result was attributed largely to the fact that L-tyrosine increases brain levels of dopamine, which is believed to control cognitive flexibility. ADHD Treatment and Focus Enhancement A 2011 study of both adult and pediatric ADHD patients showed that 77% of patients treated with L-tyrosine alone showed significant improvement over a period of 10 weeks. Further studies indicated that the positive effect of pharmaceutical ADHD medication was markedly enhanced by the simultaneous administration of L-tyrosine. Anecdotally, even individuals without ADHD report enhanced focus from L-tyrosine supplementation.

Perfect Powder!!
I have struggled lately with being able to focus as much. I have been burning the candle at both ends, so I am grateful I found this product! Iโve heard that this L-Tyrosine can be a highly effective nootropic for boosting cognitive function. Almost immediately I noticed this really helps with stress and is particularly helpful in maintaining cognitive performance when youโre under practically any kind of stress. If youโre unsure if this will help you, give it a try! I have heard others have had success when dealing with ADHD/ADD using this when stacking with ALCAR (Acetyl-L-Carnitine). ALCAR easily crosses the blood-brain barrier and itโs particularly effective. If youโre considering trying this supplement, jump inโฆyou wonโt be disappointed!

Tired? Stressed? Take this!
I have been taking 2 grams of this product everyday for a week now. I have noticed already some benefits. This products helps with fatigue. I may be tired from lack of sleep or working, but I still feel up to help around the house or in the yard. This product helps with how your brain handles stress and anxiety. I don't have a lot of stress in my life, but I have seen my wife handling calls from her sisters and mother better. She takes about 1 gram everyday. Haven't noticed any bad taste with this product, but we mix it in juice to mask any strong tastes. We have started taking this with other products provided by BulkSupplements, and they mix well together. The only complaint we have is actually with the bag it comes in. It is a sturdy zip-lock bag. The sealing mechanism does not want to work very easily. It could be because of the rigidness of the bag. As the product contained is supposed to be kept dark and dry, the seal not wanting to work easily to the bag closed is annoying. Overall, I would recommend this to anyone.

Lowers my prolactin
This has helped to lower my prolactin. And increased my dopamine (feel good hormone). My hormones are getting balanced better everytime my labs are ran! I wasn't depressed before, but Tyrosine has helped me feel more motivated to get stuff done. And to even go for a walk. Finding myself happier & losing weight more easily. I started at 500mg & just went up till I felt normal. Typically, take around 2,000mg a day now. I read it's safe to go up to 5,000mg a day. Tyrosine needs a slight sugar spike to cross the blood/brain barrier, so I just shoot it in a little water before my first bite. And I don't take it with any other aminos since they all compete with each other. Although a non-essential amino acid, tyrosine is one of the most important. It's the precursor to the neurotransmitter dopamine, and the stress hormones adrenaline and noradrenaline. It's also the precursor to the two thyroid hormones T3 (triiodothyronine) and T4 (thyroxine), plus melanin, the pigment found in hair and skin. It's part of the enkephalin peptide involved in regulating and reducing pain, and increasing pleasure. Lack of protein and stress lower tyrosine levels, with a subsequent reduction in dopamine. A drop in dopamine increases levels of prolactin, the hormone of lactogenesis, but also an inflammatory hormone. Dopamine is essential for a normal sexual response, increased prolactin causes a drop in libido. Tyrosine is essential for any stressful situation, cold, fatigue, emotional trauma, prolonged work, sleep deprivation, it improves memory, cognition and physical performance, and is used for weight loss treatments. ADD patients have significantly lower levels of tyrosine, phenylalanine, tryptophan, histidine and isoleucine. Acute, uncontrollable stress depletes dopamine, leading to depression and a rise in cortisol, tyrosine reverses this. The rate limiting step in dopamine synthesis is the enzyme tyrosine hydroxylase. Insufficient levels of vitamin D inhibit tyrosine hydroxylase, resulting in a disturbance in the dopamine pathway. This is essential for motivation and vitality, levels rise when rewarded, resulting in feelings of pleasure. A lack of tyrosine can lead to addictions to tobacco, alcohol, marijuana, cocaine, heroin and glucose. These substances raise dopamine levels. Tyrosine is used effectively for substance abuse.

Can you say... ahhhhhhhh! (?)
Occasionally I get stress related depression if too many life events (good and/or bad) happen too close together. Nothing bad enough to see anyone about, but enough that I am over-tired, forgetful, cranky and not really enjoying life. I also have a thyroid issue that is controlled by prescription strength desiccated thyroid. From what I have read, I understand that L-Tyrosine is essential for neurotransmitter and thyroid hormone synthesis, and is important nutrient for healthy adrenal function, supports the thyroid gland and promotes a positive mental state and healthy stress management. I take 1/4 teaspoon in the mornings along with my desiccated thyroid. For me, it worked almost immediately and within a few days I was less tired, forgetful, and cranky. It helps me to focus at work. I am thinking about adding another 1/4 teaspoon before lunch. There is some thermogenesis but not a lot. I put some of it in a large empty brown pill bottle (by rolling up a clean paper into a funnel) and the rest in in the cupboard. I put a label on it that tells me when / how much to take. That way I don't have to mess with the zip closed envelope. There is no real taste. I just put in in my mouth ad water and swish. Done. Update: I have been taking it in the am for about three weeks and I feel like my old self -- the self I haven't seen in a while... my creative self. <3 this stuff.

Helps my focus and mood
First off, a review of the quality of the product itself. I've ordered plenty of supplements (5 total) from BS and have always been more than pleased with their products. I can't attest to the actual quality of the products because I've never actually run full scale lab tests on them, but I'm sure they are pure and what they are advertised as being. As for the tyrosine itself, although I haven't experienced the same dramatic effects as other reviewers, I do feel as if it's improving my focus and general well being. Before supplementation, there would be days where I feel sluggish, unmotivated, and would daydream constantly. This would lead to lack of productivity and even anxiety as I often felt as if I was wasting my life. Ever since the first day I began supplementing, I noticed (within the first 15 minutes actually) that it was much easier to get "into the zone" and be productive. This in turn has improved my mood because I actually feel as if I'm doing more with my life. I've experimented with different dosages ranging from 500mg once or twice a day to as high as 2000mg just in the morning. I don't feel much of an effect with dosages under 1000mg and don't feel as if splitting up the dosages throughout the day makes any difference. For me, 2000mg in the morning has been the most effective and I'll continue this dose and slowly taper it off. I also take 200mg of 5-htp (also from BS) at night to help balance my levels of dopamine and serotonin. I'm still experimenting with dosages and plan to taper off, but for now, these dosages work well for me.

Think twice, and google the side effects before using.
Increased energy, increased mental alertness, elevated mood, increased visual clarity as well. What can I say? And it seemed to come on in about 20 minutes with essentially no taste (I stir it in plain water), doesn't clump up. I've been taking 1/2 tsp twice or three times per day. No problems. Feels natural, not like caffeine or stimulants. LATER: after taking this product for a month, which amount I lowered to about 600 mg twice a day during that time, I found these unwanted symptoms in addition to the positive ones listed above: increased irritability, angry outbursts, inability to pronounce occasional familiar words (anomic aphasia). It seems to work like a mild form of amphetamine, with the initial elevation and subsequent irritation, etc. Even in the small amounts I took it. So for some folks this might be great, but for me (and a friend taking it at the same time) it was NOT.

To balance with L-Tryptophan
If you are eating L-Tryptophan, L-Tyrosine to balance out. If you don't balance out, your mood will be pretty dull.
