BulkSupplements.com L-Tyrosine Powder Sports Nutrition Amino Acid Supplement Unflavored And Gluten Free 500 Milligrams Per Serving 100 Grams

As advertised. But get a food grade container to keep in. The reviews about the zip lock not working was correct. First use it would seal. No biggie tho. Its better to keep it in a container.

Seems like a decent value for the money. Its a cool unique product i heard about on the internet. It looks just like powdered sugar. I just get a spoon and mix a little bit like 500mg in with any type of juice/milk/drink 2-3 times a day to treat my severe Attention deficit disorder (ADHD). It tastes good! I have no side effects so far after 3 days of taking it with the prescription drug Strattera. It seems to make me focus better, i have a better attention span and i am somewhat less distracted. My only suggestion is to get a food clip used for a bag of chips to keep the bag shut since the zipper doesn't really work, but that's not a deal breaker for me. I actually was very surprised to get an email from an employee offering me a free complimentary sample of the smallest size of any one single product of my choice shipped to me!! Talk about top-notch customer service.... i have nothing but respect for people that go the extra mile to make people happy. Two thumbs up! I will definitely be buying from bulksupplements again in the future. :)

Affordable, no-frills tyrosine that mixes easily into anything for a clean focus boost.

I increased my rating from 4 to 5 stars because I realized there was a much easier way to prepare my L-Tyrosine such that it is easier to measure out a consistent amount as opposed to the way I had been doing it previously.I still mix 32 oz at a time as a suspension. I originally diluted it such that 1 tablespoon would provide one dose. The problem was that the suspension was too thin, and it would start to settle almost immediately after I stopped shaking it.I now concentrate it such that 1 dose = 1 teaspoon. Now when shaken, it doesn't even start to separate for a few minutes because of the thickness. As an added bonus, the 32 oz of suspension lasts 3 times as long as when I was mixing for 1 tablespoon doses. To make it as bit more palatable, I add 8mL of Mio Fruit Punch flavoringMiO Liquid Flavored Water Enhancer, Fruit Punch, 1.62 Ounce Bottleso it actually tastes good! It ends up looking almost exactly like Bismuth subsalicylate, so if that is a problem for anyone for some reason, I'm sure a different flavor of Mio would work just as well. Great product at a great price as usual. Not an issue with the product itself, just that this bulk powder does not lend itself as well as others for the process I use.So now one of my bottles of supplements is technically a suspension as opposed to a solution. Just have to remember to shake it before dispensing. I just realized I took away a star because I need to shake the bottle first. I must admit that makes me sound a bit lazy and.or weak. Maybe I need another supplement that will enhance my bottle shaking ability. :-)

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 doesn't directly stimulate the production of these neurotransmitters, it does provide a "buffer" 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 body's ability to burn fat.Because the body can produce adequate amounts of L-tyrosine, supplementation isn't 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 EffectsThere 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 StressA 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 "buffer" 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 DemandA 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 FlexibilityA 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 EnhancementA 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.
