Acetyl-L-Carnitine HCL Powder

Acetyl-L-carnitine, also known as ALCAR, is an acetylated form of L-carnitine, a supplement often used to support athletic performance. Carnitine molecules are generally used in the body in the process of transporting fatty acids to your cells’ mitochondria. From there, the fatty acids are broken down to produce energy, hence why athletes include carnitine into their diets. As a nootropic supplement, acetyl-L-carnitine HCL powder offers a variety of potential uses and benefits.

How Acetyl-L-Carnitine HCL Powder Works

L-carnitine is a compound that is produced naturally in the body. The compound is then transported to the heart, brain, and other tissues. L-carnitine can also be obtained from certain food sources, primarily protein like lean cuts of beef and pork, poultry, and some seafood. L-carnitine can also be found in dairy products, like cheese and ice cream.

However, when taken as a supplement in its plain form, L-carnitine has low oral bioavailability, meaning the body has trouble absorbing much of the compound that you take. The acetyled form allows for much easier absorption.

Acetyl-L-Carnitine HCL Uses and Benefits

L-carnitine and acetyl-L-carnitine share similar structures, but their effects differ. L-carnitine is primarily used as a supplement for supporting physical energy while acetyl-L-carnitine HCL benefits are much wider and varied.

ALCAR is used to potentially boost the metabolic energy of your brain cells, which may support your cognitive processes. 

Acetyl-L-carnitine may also support mental energy, concentration, and focus. Some people taking this supplement also report experiencing clearer thoughts and greater alertness and perceptual awareness.


ALCAR breaks down and can form with choline to form acetylcholine, an important neurotransmitter.

Studies suggest that this increased cholinergic activity in the brain may lead to a variety of cognitive benefits, including:
⦁ Improved capacity for working memory
⦁ Improved reasoning abilities
⦁ Improved long-term memory formation
⦁ Improved memory recall
⦁ Increased learning abilities and fluid intelligence

Acetyl L-Carnitine Dosage

As a dietary supplement, take 500mg of Acetyl-L-Carnitine once daily.

    Gets me motivated

    I take this with Cognizin and Alpha GPC. I'm not sure which one is doing what, but I am far more motivated than I was before.

    Excellent Quality

    I have bought this stuff from other companies. And it's not that good... the powder from Nootropics is excellent.

    acetyl l-carnitine hyrdochloride

    I am using as a part of a general alertness and wakefulness stack. My evaluation is not controlled, however, taken as a set/stack with other nootropics depot compounds, it appears beneficial at first blush.

  • Jason - 18th Jan 2019

    Some respond differently

    I responded differently. I started with 500mg. It started with a fairly intense lift in mood, followed by intense irritability and then a really strange depressive crash and diarrhea. Turns out I need closer to 50mg. Just a thought for anyone who has never used this supplement. It lifts my mood and gives me clarity of thought with a little energy. Too much makes me irritable. Tastes a bit like malic acid.

    Great energy source and mental stimulation

    I can feel myself wanting to do more and feel more motivated to do things while taking this product! I notice on my Fitbit that I take more steps during the day and walk more miles. I definitely get more done while taking this supplement. I have more energy. I am mentally more stimulated. This pairs well with racetams and cholinergics.

    Nice shop

    Exactly what I wanted

  • alchemist●22 - 13th Aug 2018

    purity is evident. helps a ton with fatigue (paradox exp.)

    After my numerous concussions and a few TBIs, I've found that stacking 500mg to 1.5g (.5 3x) with ani (and choline), sensoril, and noopept (up to 7x a day- too much for most) is a bomb stack for anyone with a history of brain trauma. The purity is evident to sight by the chunks that accumulate not long after first opening and extremely acidic taste. The paradox however I've found is that if I dont have a protein rich breakfast followed by a full lunch and dinner i end up hitting a wall about 6-10hrs after first dose. Likely from increased metabolism.

    Great product

    Works as advertised.

    High quality and fast delivery.

    All of my orders have been handled in a speedy and professional manner. I’ve been confident with the quality of all my orders. I’ve have dealt with complications in purity and shipping issues from others venders in the past, but I’ve been very satisfied with nootropicsdepot.

    ALCAR has a very noticeable effects of clearing the mental cobwebs for me.

    i love it

    Alcar is pretty awesome and when i mix it with bitter stuff, it tastes like citrus!

  • Andy - 15th Mar 2018

    does give you a lot of energy

    This thing works and gives as much brain energy as body energy. Highly recommend this for everyone. Also it helps with the Acetyl Choline cycke

  • Alex - 17th Feb 2018

    Very powerful

    This is the first time I order ALCAR from nootropics depot. I use it for weight loss, however, it's a very powerful supplement. I use it in combination with Na-R-Ala, the combination seems to work great for weight loss. All in all, I'm very satisfied with ND and the product.

    Best regards,

    Necessary for lifting and work

    I work in the contruction industry so taking this two times daily has helped in the gym and at work.

    A Workhorse Cognitive Supplement

    I read quite a bit of research on this stuff awhile back and have been taking it since. There always seems to be a certain grit, intensity, or seriousness that is added to my cognition when I take this. Its one of the many supplements that has yielded success in clearing brain fog time and time again. Little to no tolerance issues with this stuff. On days that I take 2g, major productivity usually ensues from a cleaner perspective.

  • Unknown - 25th Sep 2017

    good product

    noticeable effects on cognition, mood and energy.

  • Unknown - 7th Aug 2017

    along with NA-R-ALA

    So far, so good!. Can be a little rough on the gut between the two, but many other benefits to both.

  • Unknown - 30th May 2017

    Best service

    Very good quality, fast delivery. Keep up the good work :)

  • Glen R. - 20th Apr 2017

    Great Quality

    The ALCAR supplement I purchased recently is of very high quality.I also really like the plastic tubs,which to me,are the best way to ship,store,and use supplements.Reasonably priced,as well.Highly recommended to anyone looking for a great source for ALCAR.

    Best ALCAR

    Best ALCAR I have tried. It gives the usual effects of ALCAR, but this powder is finer and seems to taste slightly better than my usual ALCAR powder sources. Strangely, I don't notice any GI side effects of taking 5g+ of this ALCAR, whereas I struggle to take 2 grams of the coarser powders
