I think this cured my ADHD
I took this without expecting much of it, but one month in I realized my mind was less messy. The constant influx of thoughts in my mind has stopped! The sudden bursts of energy (which leave me drained after) has stopped. I'm able to keep my mind in one place, I can focus!! My moodiness which I usually have little control over has vanished! I don't know how it worked so well for me, but I'm glad it did. I'm less impulsive and my short term memory seems to function like a normal human being now. (Since it doesn't struggle to hold onto one thought in a tsunami of thoughts in my explosive mind anymore). It's nice.

Life Saver! Great Product!
I ordered HCF after reading about its benefits in aiding with discontinuing antidepressants. I've been really happy with the results this far. I've started a taper off from a SSNRI medication that I've been taking for about 6 years and the withdrawals can be extremely nasty. I feel that HCF has helped me GREATLY with withdrawals. I feel, well... Happy, Calm & Focused. Something thing that I haven't felt in YEARS! My family and co-workers can attest to the improvement in my mood since starting HCF at the beginning of April 2016. Over the past few years I've struggled with awful moods, none of which were nice. There were days that I was literally afraid that I may actually hurt someone from the rage that I was experiencing. Then the next minute I was beyond sad. It was everything I could do to get through a day without crawling into a hole and crying. When I realized that it was the medication that I was taking causing me to be so unbearably miserable, I told my doctor that I wanted to stop the medicine. His response was to just stop taking it! BIG NO NO! The withdrawals from these medicines WILL cause you to go insane if not something a million times worse! Especially if trying to stop cold turkey! After I researched for weeks on how to get off the meds without ending up in prison or dead, I came across a post where others had used HCF to decrease the withdrawal symptoms and thought what could it hurt? I'm nothing less than amazed and SO glad that I gave this supplement a try! I still have a ways to go with getting off of the antidepressants completely and I am confidant that HCF will help with my progress. I would recommend this product to anyone trying to live a better, happier life. The results aren't immediate and you may not be the first to notice the difference in your improved mood, but when you do, you will be amazed! I haven't felt this good since before I ever started taking the antidepressants back in 2000! I'll admit that the price is high and that is the ONLY draw back that I have on this supplement, but it is worth the price as it works for me.

Helping with my ADHD symptoms!
UPDATE: I am still amazed with this product AND my doctor has approved my use of this in place of Adderall! *** I am not stating this course of action is advised for everyone, please discuss with your own doctor *** My doctor did urge me to get back on my anti-anxiety meds, because HCF does not increase seratonin and he said the side effects of discontinuation are very unpleasant after a few days... I have to admit I did not start that back up as I was not feeling anxiety or any unpleasant side effects from stopping the anti-anxiety medication - it's been almost 3 weeks. I realized that I suffered from anxiety because of the symptoms of my ADHD... Adderall was helping some but actually increased my anxiety levels. With HCF, I am getting the focus I need and staying calm through it all. I have gotten SO much done, and in fact we are in the process of trying to buy a home and sell our current home at the same time. It's enough to make any normal functioning person go coo-koo, but the HCF has made a huge difference. Right now my mind is distracted and so much going on but I know that once we're moved and settled I'll be able to focus even better than ever! My sleep was a little odd at first, not so much the sleep itself but my dreams were darker, I'm guessing the lack of anti-anxiety and seratonin.... after about 3-4 days my dreams started to feel normal again. I can wake up on weekend mornings now and get things done. I organized a ton of my belongings in one weekend whereas before HCF it was an ongoing struggle and years have passed without being able to complete any organization projects! I am not feeling any physical side effects. Also, with the Adderall, on days I didn't take it, I was in a zombie-like state especially on weekends. 2 weekends ago I went 3 days without HCF and functioned normally, still able to figure out what I needed to do and remain calm. I'd have to say my only complaint is that it costs way more than my prescription with insurance, and that I have to take 3 pills at a time (once daily). I wish the pills were smaller and that 3 wasn't required, but this is so minor, the results more than make up for it! I have combined ADHD and have been taking Adderall for about 18 months. Unfortunately I also have been diagnosed with anxiety and mild depression so I was also taking an anti-anxiety medication, which I recently learned can cause the Adderall to have a stronger effect. The 'stronger effect' I was feeling was more in the area of even higher anxiety and a block of time each day I would feel overly happy and have more hyper activity in my brain, not so much increased focus or productivity. I needed to keep taking it to counteract the increased anxiety that is caused by the Adderall. If not taken, I would worry more and have racing thoughts, racing heart rate, etc. I have good health insurance so the total cost of my meds for me is average $70 per YEAR. This supplement costs $40 per month. Huge difference in cost, however, sometimes it's worth it when it comes to your health. Of course I don't want to end up overdosing on seratonin (or at least feelings that are associated with it) so to try this supplement out I have not taken either my Adderall or anti-anxiety medication for a few days while using HCF. It's only been 2-3 days but I have noticed a huge difference. I am feeling exactly how I think I should be... calmer and more focused. Too soon to tell about the happy part but I have noticed even troublesome events at work this week did not seem to have as much of a negative impact on my thought processes and emotional well being as before. I can sit for hours and stay focused and driven to be productive and I'm finding myself less distracted and less unnerved by irritating elements of my tasks. Today I was actually working on something very boring and tedious and I got through it without the usual emotional stress and needing to stop to do something interesting. Actually just the thought of getting it done and over with was interesting enough to power through! The Adderall does help me with work productivity, however, I still find myself day dreaming, very unorganized and messy, and mentally hyper that has it's good points and bad. I still agonize and procrastinate over little things like making a phone call or just taking care of a small thing that wouldn't be any issue for people without this disorder. I also still have a terrible time making decisions, and trying to organize things at home is a painful and very slow process. At work it's a little different, I can quickly decide what to do with papers and files, it's just finding the time to actually do it that is challenging. This weekend I will be finding out how the HCF affects my ability to take on organizing projects, etc. With the HCF at work, I find myself taking care of things without giving it much thought, and much less irritation and frustration when I come across an issue that could have potentially set off an ADHD meltdown, even when on Adderall. With the Adderall, if I didn't take it by 11am, I couldn't take it for the day because it stays in the system 12 hours and I wouldn't be able to sleep. Then with the anti-anxiety, I would sleep too much (even if taken in the morning). I could easily sleep 12-15 hours a day on weekends which isn't fun when there are things I want to do. Although the directions for HCF say to take in morning, I have taken it as late as 1pm and it doesn't effect my ability to sleep at a decent time, I actually find myself more tired in the evening which is a good way to motivate me to get to bed at a normal time. I am planning to continue to take it without my other meds for the duration of the month's supply and will update when it's done. I need to talk to my doctor about using this in place of the meds, and I am interested to see if this is more helpful in the long term. The idea of being on those prescription meds for the rest of my life is daunting and if HCF helps me do what I need to do and feel better overall, I'd rather take a supplement even if it costs a lot more. I am testing out the results of this supplement vs. prescription meds for ADHD and anxiety, and will discuss with my doctor. I do not recommend anyone replace their prescriptions without discussing with their doctor. I do not know if this will be a good alternative in the long run but so far I am very pleased with the results and hope to make a decision with my doctor that will be better for my health.

Amazing! Has changed my life!
I'm 49 years old and I've been suffering from depression on and off for the last 2 years. In addition, lately I've been having memory problems and just feeling my mind was very foggy. Also I've been studying the piano for the last 4 1/2 years and I noticed that I was having more and more problems learning pieces. I've taken multi-vitamins before but either they seen to offer little benefit or they make me irritable. I do take a B vitamin supplement which seems to help with energy and with my mood but it didn't do anything for my focus and memory. I started looking online for supplements that would help with these issues but I wanted to stay away from anything that seemed risky or unproven. I came across HCF on several websites and it was always ranked in the top ten. The ingredients seemed along the line of what I was already taking- the B vitamins and the explanation of how the product worked made sense and didn't seem risky. I've been taking HCF for two weeks and it has changed my life. The first day I took it- literally within an hour I noticed a difference. After a few days the change in how I felt and the clarity of my mind was undeniable. Not only is my mind clearer and my energy levels higher but I feel more positive, relaxed and motivated. My piano study has also shown significant improvement. Pieces seem to easier to learn and I am sight reading much faster. I've only written a few reviews for a products even though I've spent thousands on Amazon but I am so impressed and happy with the results of this product I just want to share what it has done for me in case others might benefit. I don't know that it will work for everyone but it has certainly helped me. Also, I'm very sensitive to supplements and medication so I've only been taking one each morning rather than three. One day when I was feeling extremely sluggish because I hadn't slept well, I took a second one which really helped me get focused and energized for the remainder of the day. HCF came with some literature explaining how the product worked which I really appreciated and which helped me understand the product better. If I continue to have the positive results I've experienced in the last two weeks then I imagine I will be a life long customer. Great product! Update: I've been on HCF for a couple of months now and I can't believe the difference it has made. I can play piano longer with greater focus; I don't get those energy crashes in the middle of the day anymore; and overall I just feel more motivated. I take it religiously now. I'm still only taking one a day which seems to work fine for me. If I'm feeling like I'm starting to get a little foggy or down then I sometimes take a second one during the middle of the day. Again I don't know that it would work for everyone but for me it has been a miracle!

I looked at the ingredients which appear to be good, EXCEPT for the Folic Acid
My 13-year-old son has ADD, OCD, Asperger's, Anxiety and Sensory Integration Disorder. We have tried many things, including medications, you help with his focus problems. Nothing has helped. I heard about HCF through a teacher of a friend's son. She (the teacher) was taking HCF and swears by it. I looked at the ingredients which appear to be good, EXCEPT for the Folic Acid. I was very disappointed to see that. Folic acid (synthetic version of folate) is now known to have detrimental health effects, especially in those with MTHFR variants/mutations (which it now estimated affects almost 50% of the U.S. population). I know about this because I have a variant of this gene, which inhibits my ability to convert folic acid to folate (the form my body can use). Folic acid competes with folate for positions on the cell receptors and bogs down the cell's ability to absorb the bioavailable folate. Having said all of this, HCF does seem to have had a positive effect on my son. His teachers report better focus (initially). And he reported feeling "happy" after the first dose. That effect seems to have worn off, so I think we would have to increase the dose to get the effect we're wanting. However, I can't, in good conscience, continue to give my son something containing folic acid (the full daily recommended amount in one dose), knowing how the body handles it and how it blocks the body's ability to absorb folate and actually builds up in the body (because they body has difficulty processing folic acid, regardless of whether or not someone has an MTHFR variant). If this company decides to make a version of this product with Methylfolate (5 MTHF), I would DEFINITELY buy it again. I think at that point, it will be a WONDERFUL product that everyone could take (including those with MTHFR variants/mutations). As it stands, I'm stuck with a tough decision - have my son continue taking this product for the focus benefit, knowing the detrimental effect of folic acid, or go back to the way things were from the lack of focus standpoint. I will be researching other products to find something comparable without folic acid.

New formula causes severe anxiety!
I purchased their old item many times that used to be in the blue bottle. It was so helpful for me and my chronic illnesses. It gave me the motivation and energy boost I needed and calmed my nerves. However - and this is a big however They changed the formula—B6 jumped up seven times what the original formula was, they added active P5P, folate switched to methylfolate, and amino acids (the important part) were reduced/altered. This made it significantly more stimulating and caused severe anxiety for me. It was very scary. I didn’t feel like myself at all and I was terrified. I had extreme jitteriness. I almost took myself to the ER. I really wish they would switch back to their old formula, that worked so well for sensitive people like me! Make sure to check the dates on the reviews, if they’re prior to 2025 or so, you can’t rely on those reviews because they are based off of the original formula. Read the new reviews since they reformulated and you’ll see many had experiences like me.

My focus is much better and my sleep has improved the feeling of calmness
I am an experienced kitchen chef, who lately has come under quite a bit of ‘on the job’ stresses. The problem is basically this; I am spread way too thin these days. I have, as of the last year, had problems with many things such as memory, mood and proper diet. My wife recently voiced her concerns to me and this is when I began my quest for some type of aid or supplement that could maybe help me with some of things that I was experiencing problems with. As said, I believe it was due to the fact I was under so many stresses, a new constant in my life, where as before, it was here and there. I work at a very busy restaurant and over the course of the last 3 years we have been whittled down to a skeleton crew. My job carries more responsibility and tasks on a daily basis than it ever did before. I have to remember this and remember that. Being stretched so thin began to wear on my faculties and mood. Again, my basic problems were mood and memory, accompanied by improper diet and rest. I did some initial research and found an herbal supplement that seemed to work for a short while, but then didn’t at all after that. With that experience under my belt, I was very wary to make another purchase of any kind as these supplements which are quite often very expensive. Due to the fact that my work wasn’t going to get any easier anytime soon, I did focus a bit more on rest and proper diet, but still kept my mind open for something that could maybe help me out a bit more in my current situation at work and at home. With my improved diet, I did notice some changes in my mood and energy levels, but I was still having some trouble with attention and memory. I have been taking it now for just over a week and I notice enormous changes in my calmness and mood. My focus is much better and my sleep has improved the feeling of calmness, that’s what I’ve really noticed right off the bat.

Not for everyone with ADHD/Depression
I have ADHD and minor depression. I often drive myself crazy trying to remember a thought I just had, not to mention misplacing my keys or wallet often. My mind goes in loops trying to remember the thought I just forgot . Plus I’ve been unemployed going on 5 months, after having lost my entire life savings last year. I’m not depressed, but I do have periods of melancholy. My faith in God is what keeps my head above water. Anyways, I’ve been taking Neuro-Peak by Zhou Nutrition for 3 years now, 2 pills a day. It really helps with my misplaced thoughts without any side effects. I’ve experimented by stopping doses for a few days and no side effects. I just go back to misplaced and hazy thoughts. Well I decided to try this based on reviews and thought it could help my mood. Unfortunately it didn’t and I even had suicidal thoughts while on this. I did stop taking my Neuro-Peak pills while switching to this. Anyways, the first few days on this, I had unwarranted anxiety (which didn’t help going into a job interview). I finally adjusted, but there were some days I felt very depressed, even suicidal. After about 3 weeks, I knew this wasn’t for me and so I stopped. Unfortunately the withdrawal caused me severe insomnia. Not sure what’s in this stuff, but be careful. I’ve since went back to Neuro-Peak and things are ok now. This is just my experience with HCF. Perhaps yours will be better...
