Review: 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.desertcart.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.
Review: 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 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 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 “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 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.

## Questions & Answers

**Q: How many of you were paid with free product to write a review?**
A: I was in the past for a diff product and not just by this company. Our reviews are more important than people realize. 

Allow me to enlighten. Your doctors will not tell you what these supplements can do because what they can do and say is heavily regulated by the FDA. Naturals are not because they are not uniquely created compounds that can be patented and sold for hundreds and thousands of dollars. For instance, a month's supply of brand name A**** usually is upwards of $900. A month's worth of X****, exclusively produced by one company in the US and only distributed by one US pharmacy and requires an extensive process where you get to know your pharmacist by name, ends up being about $6,000. Yes, for a one-month supply. Natural alternatives to these are either illegal or not at all regulated, so information varies and possible side-effects, contra-indications, and drug interactions are hard to find and take a lot of research. So, finding a trusted, good quality brand is a process of trial and error, as well. 

All of that, kids, is why these online reviews are so important. We are one another's best source of information, down to the best ways and times to dose and what to ingest it with. I have been offered free product of my choosing from this company in the past in exchange for a review of a different supplement. Both products were of good quality, packaged well, came in a timely manner and I have yet to order anything from them that I was not satisfied with. This is just one of my go-to brands and this marketing tool is no different from what many similar companies are doing. Not nearly enough people know about these and who doesn't love free stuff? We are killing ourselves with pharmaceuticals and even OTC meds (the warning labels on all ibuprofen products literally list death as a possible side effect). So, this keeps customers happy and gets vital info out there that is intentionally obscured and hard to find. You're welcome.

**Q: what do you mix these with?  is there a bad taste? Thanks!**
A: I did not experience a bad taste.  I mix 6 grams of L-Tyrosine and 3 grams of L-Glutamine and 2 grams of Optimum Nutrition Amino Energy.

**Q: What is the expiration date?**
A: I have some NOW FOODS tyrosine powder from 2009 that I always kept refrigerated. It is still snow white. I have been using it and can feel the difference so it must be good if not at 100%. I am about to run out so will order more of the same or this one from Bulk Supplements. The price of the two is almost the same when ordering a pound of either. NOW will price out at $24/pound while Bulk Supplements is the same price but for 500 grams which means it is roughly 12% more tyrosine per dollar. Buy one NOW tyrosine powder and now you have a clearly marked largish container to put 25% or so of your Bulk Supplements tyrosine into.Taking just less that one level teaspoon in the morning on empty stomach and same or half the dose in the evening. Get some 7% Lugols at ebay and rub into your skin where it is hairless such as your forearm. Or shave hair arond your stomach with a beard trimmer. Rub Lugols in there.The two make a thyroid booster. Add B6 from bulk supplements and you are making dopamine according to this Amazon review>>>>>>>https://www.amazon.com/product-reviews/B00ENQL6A0/ref=cm_cr_dp_srch?filterByKeyword=dopamine&search-alias=community-reviewsI am MD who's taking this product along with vitamin B6, Tyrosine is converted to Thyroxin and Dopa.The Thyroxin is the main hormone produced by the thyroid gland, acting to increase metabolic rate and so regulating growth and developmen.The Dopa is converted to Dopamine in the presense of Vit B6. Dopamine is my target. This product relay helps with focus and concentration. This combination definitely seems to be doing the job. My overall daily outlook is much more positive, and I am beginning to realize how nice it is to be cheerful again. Life's daily tasks no longer seem like overwhelming chores, and people no longer seem to be suspect.So far, so good; I'm very pleased!Recommended!

**Q: How much longer will the 3.5 oz powder last compared to the 100 capsules?**
A: It depends on the size of the capsules. 3.5 ounces is 100 grams which would be equal to 200 each, 500 mg capsules or 133 each, 750 mg capsules, or 100 each, 1000 mg capsules. This is assuming an accurate scale to weigh each dose. The bag claims a dose is 400 mg, which would be 250 doses. If you use a scoop, weigh out ten scoops and then take an average to determine the dose over time.

### ⭐⭐⭐⭐⭐ Perfect Powder!!
*by D***N on October 3, 2025*

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! I’ve 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 you’re under practically any kind of stress. If you’re 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 it’s particularly effective. If you’re considering trying this supplement, jump in…you won’t be disappointed!
