Amazing for a Workout!
Here is a story about my experience with Acetyl L-Carnitine for my workout regiment. It's worth the read if you're considering it for more than just neurological help. I hope you get though it! Several months ago I started a workout routine that involves me going to a rock climbing gym for hours at time. The biggest problem I encountered was hitting a wall after an hour and a half or so and unable to really push myself further. I talked to my brother, who has been a major body builder for years, and he recommended this product. I was skeptical as I've tried many other supplements in the past, even ones that cause rushes of energy, and nothing really got me past the wall. The energy ones were nice too, but, rushes of energy or not, my hands and body were unable to support the constant push of strength that rock climbing requires. I ordered this Acetyl L-Carnitine mainly because it's not only inexpensive compared to some other brands, it's made by Jarrow, who's name I recognize as being top-tiered according to a lot of reading I've done, and they're capsules not tablets. I know Acetyl L-Carnitine has quite a benefit if taking daily, but I'm not necessarily after all the benefits it provides since it can get expensive. I take two capsules, 1000mgs, and a protein bar before I leave for the rock gym. I think it's good to mention I've always had a good quality protein bar before I go to the gym so the energy from it kicks in about an hour after I get there making it so I can push a bit harder for a bit longer. The first time I took these tablets after that hour and a half mark I just felt good... a bit fatigued from the constant push, but otherwise my muscles responded well. I went hard for three hours that day and couldn't figure out why, or how. I didn't think such a supplement capable of that so I didn't even consider it. The next time I went to the rock gym, two days later, I failed to take this supplement since I wasn't really in the habit of taking it yet. I had a very hard time at the rock gym that day. I crashed into my physical wall like most other times and longed for whatever made my last visit different. I thought about these supplements at that point with dim suspicion that they might have caused it. Two days later I went back to the rock gym and was certain to take the two Acetyl L-Carnitine capsules that time. Shockingly my energy level maintained and I was able to push for hours until my hands were litterly unable to support my weight. Not because of pain or me just being weary, but because my muscles hit their end point and were completely done. I've taken 1000mgs of Acetyl L-Carnitine ever since and have not hit a wall since then. Maybe it's the combination of the protein bar I eat along with the Acetyl L-Carnitine, but, either way, with results like this, I couldn't be happier! I will ALWAYS take this before I go to the rock gym going forward. HIGHLY recommended!

Helps with Mental Acuity and Gym Performance
Acetyl L-Carnitine is my favorite supplement and Jarrow is my favorite brand of it. With some other brands, I've noticed a difference in quality the pills from month to month. I attributed the slight changes in energy to general lifestyle factors until I purchased a bottle of the Jarrow brand and noticed way more consistency in my energy levels. This is a high quality product at a fair price. ---Gym---- The best way to describe the effects that the Acetyl L-Carnitine has for gym performance is: you have more energy to get passed your physical wall. I notice that when i'm lifting a particularly heavy weight, I have the necessary energy (both mental and physical) to get through the set. When I forget to take it for a couple of days, I notice that I fatigue much sooner in my normal workout. People think of these as "body building" supplements and, thus, many people shy away from taking it out of fear of becoming some huge steroid monster. In reality, Acetyl L-Carnitine provides a gentle increase in energy allowing you to get more out of your workouts. ---Mental Acuity--- On top of providing a physical boost in energy, I've noticed that this supplement also provides a mental boost in energy. After a long day of work and staring at a computer screen all day, I still feel energized enough to work out, read a book, etc. Pros - No noticeable side effects from daily use - Easy to digest - More energy in the gym - More mental energy - Consistent quality from month to month Cons - None

Very helpful for workouts, side effect: vivid dreams
I've been taking this product for more than two weeks now. I take 1000 mg on my workout days. I definitely noticed a difference. Normally, if I work out earlier in the day, I usually spend the rest of the day super tired, wanting to go to sleep. If I take this product, however, I am very energetic for the rest of the day. I am also very productive and focused on my studies. However, there are some side effects that I observed. If I take l-carnitine, when I'm not working out, I am a little too alert and I think really fast. The over-alertness creates a mental fog (sort of like an ADD feeling). As a result, I don't take l-carnitine if I'm not working out that day. One other thing I realized is that, my dreams have become very vivid and memorable after taking this product -to the extent that I once got confused if something happened in a dream or reality. The sleep is usually very peaceful and relaxing. Other than that, I'm very happy with this product as a workout supplement. However, I am considering giving it a break for a few days, because of the dream side effect.

Appetite suppression without the jitters
Carnitine is an amazing supplement. Since turning 30, I have become obsessed with optimizing my health. First, I started taking carnitine for claudication. Since starting carnitine, I have had very few episodes of exercise intolerance (prior to that, I was having serious problems with this and my legs would tense up whenever I would walk more than a few blocks). In terms of appetite suppression, carnitine allows me to not obsess about food or have too many blood sugar spikes all day. Although, I do notice that its effects wear off after about 8 hours. Jarrows is an excellent brand and the only brand of carnitine I will take after experimenting with Whole Foods generic L-Carnitine this year. There is a noticeable difference with Jarrows and it's worth paying more. My mood and overall energy has totally improved since taking carnitine, although it's worth noting that I also attempt to eat paleo about 70% of the time and I also started supplementing vitamin D3. But I do think that the carnitine is helping because I feel different when I don't take it. Highly recommended!

Caution
For my metabolism if I take one at breakfast and one in the afternoon I find that it is difficult for me to sleep but if I take it only in the morning then the effects have worn off by the time I go to bed and that my ability to sleep is not affected. This supplement is too effective so be careful using it. The effect when I take one pill in the morning is to be more energetic early in the day and it wears off (noticeably) in the late afternoon. If I take a second pill in the afternoon it is difficult for me to sleep (others have noted having vivid dreams) so I take only the morning pill and sleep restfully. UPDATE: I have started taking another pill before lunch. The reason is that this supplement is very effective and I have found that the early use of a second pill does not impair ability to sleep. ANOTHER UPDATE: After having to cope with a few days of none, because my bottle of pills ran out, I found that the effect of this supplement (given my body chemistry) was dramatic. I ran out of energy far earlier in the day. Knowing that the effect of doing without this supplement was so dramatic I decided to increase the overall rating. BEWARE THAT IF YOU TAKE THIS SUPPLEMENT LATER IN THE DAY THAT THE EFFECT WILL PROBABLY INCLUDE DISTURBING YOUR SLEEP. btw - i never give a unit 5 stars unless it performs in an outstanding way

Going to another brand (was: (5 stars) "Exceeded my expectations")
12/28/2016 When the Jarrows formula changed it's label to what it is now, I didn't think to check if everything was copacetic. I can't say for sure that in this last year or so that I wasn't receiving benefits from it because I am taking their sustained release of Alpha Lipoic Acid. I have regained my lost short term memory and regained my photographic memory. It has been wonderful. What I don't like is that this isn't high quality either pharmaceutical grade or some other certification (not self-policing) and it comes from China. It's the "comes from China" AND crosses the blood-brain barrier that has me concerned. I had this on a Subscribe & Save purchase. I have switched to a more expensive brand that states that they have the high quality stuff. Sure, I can't prove that they are pharmaceutical grade, but stating it is what Jarrows can no longer do. It's as far as I can go as far as due diligence and it is better than stating nothing and knowing it isn't pharmaceutical grade at all. That means I have to take charge and get the good stuff into my system once again. I have lowered my star rating from 5 stars to 3 stars, docking 2 stars for the lower quality grade that it is. Here's my old post before I knew they dropped the pharmaceutical grade: I purchased the acytel l-carnitine from Jarrow just because I needed it for managing my ADHD symptoms and i consider Jarrow products to be quality products. I had no other expectations of improvement for anything else that I've been having problems with. Not only did it do better than my ADHD prescriptions for some of my ADHD symptoms, but suddenly I started remembering where things were and I regained my photographic memory which I haven't seen since college! Why do I know that the improvements I experienced are related to Jarrow acetyl-l-carnitine? Because when I stopped it for 2 months prior to surgery I needed, I lost the photographic memory and regained the ADHD symptoms. After the surgery when I was given the ok to go back on it, within the same month just like when I first started with this product, I regained my photographic memory and the same ADHD symptoms abated once again. Even more so, I take 3000 milligrams of the product a day. I was getting tired of taking 6 pills during the day. Another brand had a 1000 milligrams acetyl l-carnitine pill, so I decided to switch to that brand so instead of taking 6 pills a day I only needed 3. Over the next month I lost my photographic memory and the ADHD symptoms we're not being well managed. I still decided to let this product have time to work and gave it two more months. Nothing ever got better like it was when I was on the Jarrow product. This was a no brainer. I returned to Jarrow again and after about 1 month, my photographic memory is back and my ADHD symptoms once again have abated. Jarrow, if you can make a 1000 milligrams a pill, I'd really appreciate it!
