Gave energy lost weight
I bought this purely for energy, I also started taking vitamin B complex, omega 3, vitamin D 3, and tumeric. I am fairly fit I play ice hockey twice a week I have been 180Lb’s for years. I started taking these supplements mainly for energy and to help stop any inflammation. I noticed I lost about 5 pounds within a month I had no desire to lose weight most of it came off my stomach. I am not sure why I lost weight nothing in my diet has changed other than these supplements that I added. So take it for what it’s worth. My energy level is lasting much longer throughout the day. I am not a coffee drinker or big on caffeine I like natural energy. If you do take the tumeric only take one capsule per day. 2 wrecked my stomach. I am 46 so as I get older it’s important for me to stay in shape and keep the dad bod at bay.

Been taking them every day for almost 2 weeks with a meal & I honestly feel a difference in my cravings, energy & mood which happened the first day. I’ve been looking for something to help me lose the baby weight from having my daughter a year & 2 months ago because it’s been a struggle. Down only a few pounds but I also started eating better & trying to be more active. I feel like my focus & brain function has improved too.

My title review read great supplement for your lungs. It's also beneficial to other parts of your body. Do some research and you'll find out it's a positive supplement to take. This brand is reasonably priced and is manufactured under an FDA registered facility. Serving size is two at a time there's a hundred capsules in the bottle. So you have enough to last you 50 days. Any supplements you take if you put them on auto order you'll save extra money. I highly recommend this brand.

3.0 out of 5 stars Most reasonably priced of many on here, not sure it's helping much though - UPDATED 10/16/21
Reviewed in the United States on October 2, 2021

While in the military, I had a collapsed lung, and have had aggravating respiratory issues ever since. I did some research and this supplement was supposed to help the issues I was having. Small enough and easy to take at and the price is the most reasonable of most on here. One pictured atop US Dime. As a consumer, how do we really know what we're getting with supplements? This seems okay and has no aftertaste noted. I am just not really seeing any noticeable improvements but will update if appropriate.

UPDATED 10/16/21: I ordered this mistakenly after the product N-acetyl-l-cysteine, or NAC, was recommended to me. A search of Amazon for NAC produced Acetyl L-Carnitine as results and I mistakenly assumed that these were synonymous. THEY ARE NOT. I stress this here so that no one else makes the same mistake and that you order the correct supplement. Acetyl-l-carnitine, or ALCAR, is synthesized from carnitine, while N-acetyl-l-cysteine, or NAC, is derived from the amino acid cysteine. ALCAR and NAC are used to treat a wide variety of medical conditions.

I will add that I am not finding that Acetyl L-Carnitine, this product in review, is helping with mood, mental clarity, energy, etc., to any extent noticeable to me and I changed the rating to 3 stars from 4 after trying this for even longer now. Since NAC can no longer be ordered via Amazon, I will try it (NAC) from somewhere else. But, I reiterate, make sure of what you are getting.

5.0 out of 5 stars I CAN'T BELIEVE THIS PRODUCT ACTUALLY WORKED!!!!!
Reviewed in the United States on November 17, 2019
Verified Purchase
I've been experiencing severe headaches, nausea, dizziness, fever, fatigue, lack of energy and extreme brain fog since 2014. I was age 43 at the time. I went back and forth to various Doctors, receiving MRI's C.T Scans and medications that made the condition even worse. I stopped taking all the medications, practiced holistic healing, detoxed/cleansed and went vegan for 12 months. After all that, the symptoms REMAINED!!! I became really depressed and considered suicide because I went from being a very active person to a shell of the person I used to be. On top of that, the pain from the headaches have been totally unbearable. I've been researching so many products, most of which I tried and it never worked; until I came across Acetyl L-Carnitine. I ordered it 11/13/19 and received it on time, 11/15/19. I took 2 capsules with my lunch around 2pm and took a nap because I was exhausted, which wasn't anything new. I've gotten into the habit of taking multiple naps throughout the day (in my car at work during lunch time as well) because I was always so tired. Well, when I woke up from this particular nap, I had a TON OF ENERGY!!! I went grocery shopping, ran errands and cooked. Usually after a nap, I wake up tired and ready for another nap. Thanks to Acetyl L - Carnitine I'm getting my life back at the age of 48!!!! I thank GOD that I was so blessed to find this product!!!!! Thank you Jesus!!!!! Praise the Lord!!!!!!! Amen!!!!!!!
