No cramps & improved focus
I started taking this supplement mainly for the fertility positives and I read it helps with mood support. I have had so many positive outcomes with this supplement.One of the two major pros have been improved focus & zero cramps during my last cycle. I have had cramps during every cycle I’ve ever had, not this month. And the only thing I have really changed is the addition of this supplement. I also noticed that my hair is better, skin and my muscles feel better after workouts.I cannot say enough good stuff about this supplement.

Great for cognitive and energy benefits. Pair with Alpha Lipoic Acid if you can.
Acetyl-L-Carnitine, often called "ALCAR" is an amino acid that I take with Alpha Lipoic Acid for cognitive, blood sugar, and energy benefits. I take it in the morning because I find it gives me a nice energy boost.Momentous is a top supplement company out there. If you follow Dr. Huberman, that's most likely why you are here. I feel this is a high-quality supplement. It's hitting me exactly like the ALCAR I usually take does.Acetyl-L-Carnitine isn't a cheap supplement so I think the pricing here is more than fair.This supplement also gives me a boost for my workouts as well as my desk work.It can affect your sleep at night so try to take it early or mid-day at the latest. I take it with my meals. Paired with Alpha Lipoic Acid, it protects from blood sugar spikes.Do some reading about what pairing this with Alpha Lipoic Acid can do for you and try it out. It's proven to help you cognitively and physically.

This L-Carnitine is Great Quality!
I found out about L-Carnitine about 5 years after being diagnosed with Multiple Sclerosis and being EXTREMELY exhausted. I tried prescription medicines but didn't like the way they made me feel. L-Carnitine is a nearly immediate (within an hour) acting natural stimulant, unlike any other, except a few other amino acids. It gives you energy, helps your mood, and helps your muscles work. I like the dosage of this L-Carnitine, as it is enough to give you energy, without making you feel shaky. 900 mg. is a good dose, and you take it whenever you need extra energy! Not a daily pill, unless you are exhausted daily! Contact your doctor before taking any supplement, but this is a safe way to get extra energy, a great mood, and get your muscles working properly!I rate this a great product and also a DEFINITELY BUY IT item!

Unnecessary fillers, not the best deal
This is not a bad supplement. I don't think I really noticed any dip in the effects vs. my regular brand of acetyl-carnitine, but I'm not overly pleased with the fillers — stearic acid and silica? I've appreciated the results of supplementing with carnitine, but I don't need to supplement with these.I like my regular brand (Superior Labs) which provides the same amount of active ingredient without the fillers (except organic rice flour) for a lot less per pill. Currently, this product is asking around 40 cents per pill. My regular brand? Less than 15 cents. Based on this alone, I can't really recommend it, and with the higher number of inactive ingredients, I'd also lean towards a different brand.

Great product
Momentous is a great brand, always consistent and delivers results. Been taking this less than a month and feel the difference.
