This Nutricost Acetyl L-Carnitine has been absolutely incredible for boosting my daily energy levels and cognitive function - the quality is outstanding with 500mg of pure ALCAR per capsule that I trust is properly manufactured and third-party tested, and I appreciate that it's non-GMO and gluten-free which aligns with my dietary needs and health-conscious lifestyle. The functionality has exceeded my expectations as I've noticed dramatically improved mental focus during long work days, better workout performance with less fatigue, and sustained energy throughout the afternoon without any jittery side effects or crashes like I get from caffeine, plus my recovery time after exercise has improved significantly since I started taking this consistently. It looks great with clean, professional packaging that feels medical-grade and trustworthy rather than flashy or gimmicky like so many other supplements on the market, and the capsules are easy to swallow without any unpleasant taste or aftertaste that makes you dread taking them. At this price point for 180 servings, it's incredible value compared to expensive energy drinks, pre-workout supplements, or nootropic blends that cost far more per dose - this single bottle lasts for months while providing consistent cognitive and physical benefits that have genuinely improved my quality of life, and after researching ALCAR extensively and trying several brands, Nutricost has become my go-to because the results speak for themselves and I feel confident in the purity and potency of what I'm putting in my body every day.

Acetyl-L-Carnitine (ALCAR) is a naturally occurring compound vital for converting fats into energy, supporting brain health, nerve function, and athletic performance by improving focus, reducing fatigue, and aiding fat metabolism, often used as a supplement for cognitive decline, nerve pain, and mood, with potential benefits for heart health.

Great price, but whether it works is a question that can't be answered after a few weeks. Read more

It does help with energy levels, and fighting brain fog, but in my experience not all by itself. I'd recommend pairing it with a testosterone booster supplement like DHEA and/or Tongkat Ali if you're a man, and a blood sugar regulator like Ceylon cinnamon capsules since this increases your metabolism. The only downside for me was that Acetyl L-Carnitine always dramatically increased my appetite, and made me more irritable since it burns through your metabolism. So a calming supplement like Ashwaganda helped with that, it wasn't enough to stop the increased hunger side effect. So, I discovered that with increased hunger, and fasting the body creates an enzyme called Gherlin, that makes your more hungry, and eat too much, which is one of the things that ruins diets, and keeping weight off. So, you could really ditch all the other stuff I mentioned as long as you combined this with N-acetylcysteine (NAC), which stops the gherlin production, and helps keep the brain fog, and hunger cravings away. The price for this brand is much more cost-effective than more brands of it I've found in healthfood stores. If you're taking this 3 - 4 times a day, you'll need at least this 180 quantity. Read more

My neuropathy has been getting worse over the years. Gabapentin didn't do a thing. The Doc kept increasing the dosage until I was taking a small handful and very little help. I have had some success with Lyrica, but when it gets bad, that only takes the edge off. In despiration I started searching for more ways that might help. I read an article that mentioned that many find Acetyl L-Carnitine was helpful. I searched Amazon for one with the best reviews and I ordered this product. It doesn't eliminate my neuropathy, but it has taken the edge off way more than Gabapentin and even more than Lyrica. Ask your Doc, but mine said it would be fine to take this with Lyrica. I don't always do that, but when the neuropathy is really bad I do and it is a great 1-2 punch! It may not work for everyone, but it has been great for me! I recommend giving it a try. Read more

I bought this for a PSSM horse to help her with energy. I can’t say that specifically this supplement has helped her or one of the other zillion that she’s on, but it certainly doesn't hurt and she didn’t mind the taste. Note: she can’t have high fat due to IR, so we used ALCAR instead during riding seasons. Read more
