Alpha GPC Choline Brain Supplement for Acetylcholine (60 Count, 600mg Servings) Advanced Memory Formula, Focus and Brain Support, Focus Supplement (Manufactured in The USA) by Double Wood

Everyone is different, here is my experience. Have taken 1 capsule daily in mornings for over a week. Reason for taking: Although not yet proven, I thought it probably would not hurt and may help offset the anticholinergic effects of allergy meds I have taken for years. The main thing I noticed and did not expect was my energy levels & mental focus are both greatly improved, but the flip side is I have been having difficulty getting to sleep and my deep sleep cycle has been reduced dramatically, I am also sleeping much less than usual. My daytime energy has still been ok though, but after a week on this stuff the lack of sleep is getting to me. I have energy, but getting tired from the lack of sleep. It is hard to explain. To be fair, my husband has been coughing a lot through the night with a cold, but I normally can sleep through some noise, and (more significantly) I am still waking up even when he is quiet & my mind just goes nonstop. My conclusion is that this stuff is too stimulating for me. I stopped taking today and energy dropped like a rock and now I am fighting taking a nap. I need to see if I sleep better tonight. If I am correct & after stopping these I can catch up on sleep then I may try a 1/2 capsule daily, or maybe every other day or so. Overall I think it is a good and probably effective product (I mean how do we really know what it is doing to our brains!?) I do think it may just be too strong for some people like myself.

Great stuff! Since I started taking it I've noticed my mental acuity has increased as has my short term memory.

Having done a lot of research on various supplements, I have found that Alpha-GPC is one of the strongest and most effective of the choline supplements. I bought this particular supplement for both my mother and I because pharmaceutical grade means that there are less fillers, and the product is more "pure". My mother gets 1200 mg per day because she has dementia, and this is the effective dose used in studies. For her, this is split into two. So she gets 600 mg twice a day. I take 600 mg once a day. Almost immediately, I noticed an increase in energy and I felt more mentally in-tune. After a couple of weeks, I noticed that this effect was going away and I actually was feeling more tired than before. With some research, I found out that Uridine should also be taken with Alpha-GPC as a choline regulator. So I bought the Uridine in this brand, and started taking 300 mg per day. That did it. The energy came back, and I am feeling really good. My mother is getting 300 mg twice a day of the Uridine. These supplements should be taken in conjunction with an Omega-3 supplement for effectiveness. UPDATE 11/22/16 I have changed the supplements for my mother and myself so that we are both taking multi-supplements that include most of the individual ones we were taking. Although I continued use of Alpha GPC and Uridine for my mother, I stopped taking them. I started feeling tired all the time, and my level of ambition dropped dramatically. I went on like this for a few months, and then started wondering why I felt tired so much when my sleep patterns hadn't change and my stress level in taking care of my mother was the same. One day, I decided to try taking Alpha GPC and Uridine again (2 Alpha GPC and 1 Uridine daily). Within a couple of days, my energy level increased and I feel more awake. This also seemed to improve my emotional state because I feel better. Since I made no other changes, I have to assume that these supplements have helped improve my energy level.

I started taking Alpha GPC Choline about 6 months ago together with some other NuTropics... The effects were not as I expected (like in the "Limitless" movie), but my ability to stay focused on my tasks increased by multiple 100S%. Without the supplements, I can work for hours and feel like I worked hard but didn't accomplish anything - with the NuTropics I work and I feel focused and I actually complete my tasks. I feel like I'm in "the zone" and I'm doing what I'm supposed to do (vs. getting "lost"/distracted/ or scattered). I tried to NOT take GPC Choline for periods of time - a week or two - but it showed in my performance (I'm home-based self-employed, with lots of creative work, and managing a small team). Now, for the past 4 months, or so, it became part of my every day life. I take two pills at least twice a day, at time 3 times a day. * Sometimes I combine it with genius consciousness or genius mushroom; about half of the time I take it on it's own. I also tried other NuTropics, the only constant is Alpha GPC. Based on what I read, Choline enhances the other NuTropics effects.

Quality Alpha-GPC at a fraction of the price of leading competitors. DoubleWoods commitment to quality and affordability has made me a reliable customer for years. As a direct to consumer brand the likelihood of fraud and counterfeit goods is also less of a concern. Choose wisely friends. I’m not a robot or a paid sponsor, I genuinely like the product, I’ve reviewed other merchandise of their’s in the past purely based upon quality and service, never received a freebie or a discount and I don’t need one to share the good word.

I’m studying neuroscience at Tulane U so I bought this product after learning about the neurotransmitter acetylcholine, hoping it would increase the acetylcholine concentrations in my brain. Acetylcholine is important for learning (Look up long term potentiation) as well as sleeping/dreaming. This product definitely helps both. From the first dose I took I felt like my mind was more *on* and that I was more mentally present. I was able to stay engaged in class and took better quality notes and was able to learn things quicker when I studied new Topics for the first time. Homework was less of a chore. I have to do a lot of intense studying and drugs like adderall are commonly used by my peers. I avoid them because daily stimulants only work for a short time before the quality of your sleep and waking mental state deteriorate. However alpha GPC improves the quality of your sleep. I had more vivid dreams and woke up feeling more rested. I don’t want to say this is some panacea but I have yet to find a downside to this product. It does make you more tired at night, but this makes sense because of the higher quality work your mind did during the day. And of course, you need to sleep to let your mind fully process the memories you made all day long. Bottom line: if you’re looking for a mental boost and you already found your way to this product, go ahead and try some.

I was suffering from depression, lack of energy, and my brain was just not working like it used to. I knew a lot of this was diet/lifestyle related. I decided to do something about it. I found this product because I started eating healthy and tracking my micronutrients to make sure I was getting enough of everything. One thing I was lacking was choline. While researching choline supplements, I stumbled onto nootropics. Wow, I didn't even know they existed. After taking this, and only this, I felt a substantial difference in mental clarity, speed, and overall function. I have since tried other nootropic supplements, which do have benefits but not as much of an improvement as I experienced after starting Alpha GPC. Of course I would love if there was a "limitless" pill but since there isn't, all we can do is make sure our brains have the nutrients they need to function at their best. I did try one other brand, Now Foods. It was not bad, but I could tell a slight difference. Double Wood was better. I was very happy that they started offering it as a subscribe and save item. The %15 savings helps a lot, that is why I tried the other brand in the first place. I order 6 bottles and have them shipped every three months (I take two in the morning and two before lunch). I also tried the loose powder from powder city to try to save money. After doing that 1 month, and figuring out that it was only saving me around $5/month, I decided the powder was not worth the hassle. I also felt like it did not work as well. I would say that Alpha GPC is the second best thing I've done that has helped my mental function. #1 is eating healthy. Maybe someday I will exercise too but I'll take it one step at a time.

First, I am 66 years old and in good health. I find it difficult to write reviews for supplements. Unless a person has a clone that could serve as a control and/or unless there is a dramatic effect from taking the supplement, it is really difficult to be totally objective. I have taken many different supplements over the years. Frankly, the only supplement that I have found that has had a definite and pronounced effect on me is caffeine! I take one or two caffeine pills before I run or workout. There is little doubt of its effect particularly since I eventually crash after 3 to 4 hours. As for other supplements, I always read the background science/research before I invest my money and time. In the case of Alpha GPC Choline there is little doubt about its beneficial effects. The research is quite clear. I started taking it on and off for a few months. However, for the past couple of months, I have been consistently taking 600 mg daily. The primary reason for taking it was to hopefully improve cognitive ability or at least delay the loss of it. Plus, since I run and do resistance training, I was hopeful it would benefit me in that way as well. Results: As I mentioned above, unless there is a clone to serve as a control or the effect is so dramatic that it can not be mistaken, it is very difficult to assess the effects of any supplement. The same applies to this particular supplement by this company. Certainly my training both running and gym work has improved over the past several weeks. But, one would hope that continual training with or without supplements the person would improve. So I cannot say that my improvement is due to this particular supplement. It should be noted that it has not caused me any negative side effects, so that is a positive. The science shows that the dosage ranges from 300 to 1200mg. The research done was with people who had taken the supplement for 4 to 6 months while taking 900 to 1200 mg daily. Perhaps, if I increased the dosage to at least 900 or 1000 or even 1200 mg daily the effects would be more striking. The only reason for not doing this is cost. So this review is based on the company's recommended dosage of 600mg. Since the science is very strong for this particular supplement, I plan on increasing the dosage to 1000mg and continue it for at least 4 months. I believe after that time if there was going to be a noticeable effect, it would manifest itself.Only then can I be sure of its effects. Please note that I will receive a free bottle of this supplement for this review. I think it is easy to tell that I have expressed my honest thoughts about this product. Also, this is the only manufacturer I have purchased it from so I can't compare with others. I probably selected this company because of positive reviews and cost. Anyhow, this review is as honest as I can make it. I will write another review after my personal test of taking perhaps 1000 mg for 4 months.

I've used several Alpha GPC supplements and this ranks among the top. I use primarily it to enhance my weight lifting sessions - focus, mind to muscle connection, motivation. I feel a sense of enhanced wellbeing & cognitive clarity. I find I'm able to learn more effortlessly & my self-confidence is elevated. The comedown is very gentle in comparison to other stimulants. The effects are long lasting: 4-6 hours. I find 900mg to be my sweet spot, 600mg the minimum effective dose (I'm 240lb). Stacks nicely with other nootropics.

Excelente producto, tal cual la descripción, me ha funcionado bien.

I have been using the Double Wood Alpha-GPC Choline Supplement for about three months and am very happy and impressed with the results. I'm generally skeptical of most supplements and their claims, but Alpha-GPC really seems to work for me, improving mental alertness and ability to focus and concentrate. I find the Double Wood product to be of equal quality and effectiveness to another manufacturer's Alpha-GPC which retails for almost double the price. I've recommended Double Wood Alpha-GPC to a friend and they now use it regularly as well.

Todo muy bien, son dosis de 300mg que puedes dosificar según tus necesidades. 1 en la mañana y otra por la tarde. O si lo prefieres, 2 por la mañana.

Funciona, noté el cambio a la semana de usarlo. 2 cápsulas por la mañana en el desayuno y me mantiene concentrado y alerta todo el día. No me causó dolor de cabeza ni de estómago como otros suplementos. Lo recomiendo!
