What is Acetyl L Carnitine HCL Powder?

Acetyl L Carnitine, also usually abbreviated as ALCAR, is an acetylated form of L-carnitine, a supplement often used to support athletic performance. L-carnitine is a compound that is produced naturally in the body and transported to the heart, brain, and other tissues. L-carnitine can also be found in some food sources, primarily protein like lean cuts of beef, pork, poultry, and even some seafood. L-carnitine can also be found in dairy products, like cheese and ice cream.

L-carnitine helps transport fats into the mitochondria within cells. Once in the mitochondria, the fatty acids can be oxidized and then used as fuel to create adenosine triphosphate, or ATP. L-carnitine performs this both when you are active and at rest, but some research suggests that Acetyl L Carnitine is much more effective during exercise. However, when taken as a supplement in its plain form, L-carnitine has low oral bioavailability, meaning the body has trouble absorbing most of the L-carnitine. However, when L-carnitine becomes Acetyl L Carnitine, the body absorbs it much easier and even though it is produced naturally in the body, Acetyl L Carnitine is typically taken as a dietary supplement.

Acetyl L Carnitine Benefits and Uses

    • May help promote cellular energy*
    • May help support cognitive function*
    • May help promote feelings of well being*
    • May help support vitality*

Acetyl L Carnitine HCL Nootropic and Bodybuilding Benefits

Carnitine molecules are generally used in the body in the process of transporting fatty acids to the mitochondria. From there, the fatty acids are broken down to produce energy. This may explain why many athletes aim to incorporate carnitine into their diets. Acetyl L Carnitine research focusing on Acetyl L Carnitine bodybuilding benefits found that taking an Acetyl L Carnitine supplement may support greater endurance during exercise, and some human trials found that Acetyl L Carnitine may even promote muscle recovery after a workout as well. It’s no wonder Acetyl L Carnitine has managed to make a name for itself in the fitness world. 

Although L-Carnitine and Acetyl L Carnitine share similar structures, their effects are notably different. L-carnitine is primarily used as a supplement for supporting physical energy while Acetyl L Carnitine HCL benefits extend beyond just energy boosting properties. As a nootropic supplement, Acetyl L Carnitine HCL powder offers a variety of potential uses and benefits.*

Acetyl L Carnitine research found that taking an Acetyl L Carnitine supplement may also support mental energy, concentration, and focus. Studies on ALCAR found that Acetyl L Carnitine benefits may extend to promoting metabolic energy of brain cells, which may support overall cognitive processes. Some people take Acetyl L Carnitine and report experiencing clearer thoughts and greater alertness.* In contrast to other Acetyl L Carnitine benefits, these effects might be explained by Acetyl L Carnitine’s interaction with acetylcholine. Studies were able to uncover that Acetyl L Carnitine provides dietary or supplemented choline with an acetyl group, in order to create acetylcholine, an important neurotransmitter. Research suggests that the increased cholinergic activity in the brain may lead to a variety of cognitive benefits, typically along the lines of mental energy and concentration.

Acetyl L Carnitine Dosage

    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.

    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.

    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.

    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.

    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.

    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, Alex

    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.

    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.
