What is Acetyl L-Carnitine (ALCAR)?

ALCAR is an amino acid (acetylated form of L-carnitine) that breaks down in the blood into carnitine which helps transport fatty acids to turn them into useable energy to fuel the body. ALCAR is naturally produced by the body, but supplements may enhance its effect.

ALCAR helps the body break down fatty acids into energy supporting metabolism, and may have antioxidant properties. ALCAR may help support healthy weight and may also contribute a sense of heightened endurance and energy. ALCAR when taken in conjunction with Alpa Lipoic Acid may help support mental clarity and focus.

This is a substance is considered safe when taken in the recommended doses. Any negative side effects that may result from consumption of ALCAR are unlikely. Of course, if serving sizes are not adhered to and overdose occurs, this can result in increased blood pressure, diarrhea, heart rate, and fever. However, no side effects were encountered in any of the clinical tests done on the drug, not even for children. To be cautious, however, this drug is not to be used by anyone with a history of Epilepsy or seizure.


This product is absorbed into the system very rapidly and is known to dissolve quite easily in water. While the taste lies on the sour side by a bit, this makes it an even greater candidate for mixture in citrus-based drinks like limeade or grapefruit juice.

ALCAR may have an off-putting taste and may have a slight burning sensation on the tongue. This is normal.

Legit, good quality product.

Product is pretty legit. I cant say that I feel or can tell any physiological differences because I dont think Im capable of determining such information through feeling alone, but I like it. I like Bulk Supplements and am gonna try some of their other products for sure. Its odor is minimal and I cant taste it in my pre-workout.


Must add for any Nootropic stack

As I get older, I've been noticing a slow decline in mental capacity ranging from energy levels to memory. I've been playing with different types of ingredients and stacks to help. I typically take each ingredient by itself first to gauge how it will make me feel, how long it lasts, etc. This hit me right away! Not only did it give me a boost of energy, but it helped with mood and focus. I highly recommend it! I also recommend Bulk Supplements. If you are like me where you don't have all the money in the world, but you want to make sure you get all the right nutrients, this is the way to go. You get a quality product and a lot of it for a great price. The only downside to having it in powder form is having to scoop and weigh all the raw materials out individually, but for me it's worth the money you save. The only gripe I have is that the zip lock is sometimes hard to close. It takes a little finagling. FYI - A digital scale for grams / milligrams is a must! I wouldn't try it without one.
