Product Overview

#1 Selling Protein Synthesis Amplifier five-star iSatori L-Carnitine LS3 Fat Loss Support*

Supports Healthy Metabolism*

Improves Energy Production*

Helps Convert Fat to Fuel*


L-CARNITINE LS3™ is a true advancement in L-Carnitine supplementation. It is a combination of L-Carnitine, Acetyl-L-Carnitine and L-Carnitine L-Tartrate. With this, iSatori has created a calorie free, sugar free, gluten free, great-tasting liquid that supports fat loss and metabolism.*

L-Carnitine has long been a staple in the sports and weight-loss supplement industry. Aiding in fat loss, energy production, and metabolism, L-Carnitine is a great supplement for not only those who are looking to supercharge their metabolism and change body composition, but anyone looking to optimize their performance in and out of the gym.*

L-Carnitine assists in the metabolic process of shuttling fatty acids across cell membranes into the mitochondrial matrix where energy is processed. Increasing the efficiency of this process helps the body produce natural energy more readily allowing the fat-burning process to improve. With the assistance of L-Carnitine in the energy production of free fatty acids, endurance can also be optimized and extended; as well as post-workout recovery.*

L-Carnitine LS3
Calorie Free
Sugar Free
Gluten Free
Stimulant Free



In very simple terms, the primary mechanism of action behind Carnitine is to assist in transporting fatty acids across mitochondrial membranes (mitochondria are like your cells’ furnace) so the fatty acids can then be processed and converted into energy (burned as fuel).*

How much bodyweight can I expect to lose with L-CARNITINE LS3?

Because everyone is different, individual results will vary. L-Carnitine assists in the processing of fatty acids, helping your body become more efficient at utilizing fat as a fuel, which supports overall fat loss.* Combining this with exercise and a balanced nutrition plan will increase your results. The great thing about the L-CARNITINE LS3 base formula is that it is stimulant free and can be combined with any thermogenic or weight-loss products such as LIPO-DREX™ to help your body improve its overall ability to burn fat.*

How is L-CARNITINE LS3 different than other carnitine formulas?

L-CARNITINE LS3 is unique in two very distinct aspects. First is flavor. It's indulgent and absolutely delicious. You'll want to drink it all day (and you can do so by simply flavoring your water bottle with it). Second, we developed L-CARNITINE LS3 with an exclusive blend, called CarniTone™, which combines the three most effective and clinically studied forms of Carnitine : L-Carnitine base (the most widely used form), Acetyl-L-Carnitine (the most usable form) and L-Carnitine L-Tartrate (the most studied form for recovery after exercise). Unlike most other formulas, which only contain one form, L-CARNITINE LS3 contains an exclusive 3-form blend of Carnitine to help optimize your results.*

Can I combine L-CARNITINE LS3 with any other iSatori supplements?

Yes, since L-CARNITINE LS3 does not contain caffeine or stimulants, it can be combined with a wide variety of other supplements including LIPO-DREX™ for a class-leading weight-loss stack.*

I really like this iSatori L-Carnitine! Gummy Bear does not taste 100% about but it still taste good! I can tell I have a little more energy and also is helping me maintain/cut some weight off. Great addition for your cut, just make sure you eat right and you will get some results.

With 3 different forms of Carnitine in this product, I'm really impressed with the extra energy that I am getting from this product. I had an older measuring cap that I keep with the bottle to pour out 15 ml for each serving. The taste of the Gummy Bear flavor is excellent. The only wish is that the product came with its own measuring cap as I've used other liquid carnitine products that had this along with it. But overall, you couldn't ask for a better product that delivers on energy and helping me to keep my weight in check.

The product while it does work, doesn't taste like gummy bears. It tastes great and is nice and sweet but does not remind me of gummy bears. I'll have to use the product a little longer to notice its effectiveness but still a great product

I can definitely tell a difference in my energy levels since using this product as I don't fatigue nearly as quickly. I've made sure to keep consistent with my training & diet as well as mixing in some cardio, and all combined, I feel like everything is coming together and giving me a tighter physique. The liquid l-carnitine is super tasty and easy to take each day. I'm really impressed with how well my body responded to this supplement.

The only downside was the bottle cap was cross threaded and leaked a little. Other than that it tastes like a handful of gummibears! Mixed with a little water and honestly one of the best tasting sups I have ever had. Stomach is noticeably flatter with no diet changes or additional cardio. Noticeable results in a week, I am stoked! Reasonably priced, Isotori hit a homerun with this

Isatori l-Carnitine LS3 is incredible in the Gummy Bear flavor at room tempature but it's even better cold! It's especially great for those of you who like me, had a sweet tooth! I truly believe that Liquid L-carnitine is one of the most over looked supplements on the market. I've only been using it a few days and I can feel the steady burst of energy in the morning and have felt the warmth in heating my body while it burns fat! Do not hesitate to buy this product, you will not be disappointed.

Got this bottle of LS3 to try out for iSatori, and I was blown away! First, the effects are definitely noticeable. I felt a clean energy every morning when taking LS3. It was not a big amount of energy like from caffeine, but was enough to be a nice pick me up and very noticeable. Second, the taste was excellent! Mixed berry tasted great, and was really enjoyable to drink no matter what time during the day. Gummy bear is truly out of this world! I loved it! At first I drank it shot which was a little too strong for me, but when mixed with about 6oz of water, its the perfect flavor to drink! The serving size was perfect to take on its own, or easily enough to add to another drink such as a pre-workout and make a nice drink with it. The convenience is a good feature. The price here on is great! Only $15 per bottle, plus a buy 2 get 1 free special going on as well! It is definitely worth it to pick up a bottle or 3! Overall, this is a great product, and one that is so easy and worth it to take, everyone should!

True to the name, the taste is of a generic Gummy Bear, an interestingly sweet flavor that is very reminiscent of a sugary-gelatin flavor that you get from a gummy bear. It is one of those odd tastes that although in and of itself is mediocre, it is oddly satisfying; let’s face it, gummy bears are tasty in a a weirdly chemical tasting way. This scratches my gummy bear itch perfectly, it is like that handful of gummy bears you are craving, it fills the craving without becoming overwhelming. As I said, it is the handful that you want, rather than being forced to eat a whole 5 pound bag and getting the *****. Mixed in ~5 oz of cold water was perfect, just enough sweetness to be refreshing but not sickly sweet or overly diluted, iSatori did great on this in making it match the namesake. I can honestly say that if you like gummy bears than you will like this, but if you are not a sweetly chemical taste kind of person than you wont like it. I keep mentioning the chemical taste, so let me elaborate that; it has the artificial sweet taste, it just does, but that is what you should expect. I like it, just one of those things that does it for me. As far as aiding fat loss or anything like that, well, I am not in a calorie deficit so cannot comment on that part of it. Overall though I quite enjoyed this, and would be tempted to grab some more for nothing else other than the flavor, given how cheap it is that would not be a bank breaker. Taste- 8/10 if you like Gummy Bears, 4/10 if you do not.

I recently got a chance to try liquid Carnitine to help me drop some weight. Also to help cut back on my caffeine intake for awhile. So in about 10 minutes you'll feel a warming sensation that's very subtle nothing crazy then you will begin to sweat more then you're use to. I feel L-carnitine is versatile and can be added to your supplement routine. Best of all the berry flavor is phenomenal!

I received this from iSatori to test and review. I have taken a few other liquid L-Carnitine products in the past, and the flavor of Mixed Berry was one of the best I've ever tried. I would take this before my fasted cardio in the morning, and could feel extra endurance and energy throughout my run, and felt better after as well. Recovered a lot quicker too, my legs weren't an achy-wobbly mess after a 5 mile jog. I would take the second dose around 3pm, used it as a stim-free pick-me-up during long work days. I would definitely purchase this in the future!

Received this to "test" out from Isatori! I'm not one to hype up a product I don't think performs just because it was given to me. I've only ever used L-Carnitine ( itself ) in around a 1500MG dose, or if it was in my preworkout so not sure I have just a whole lot to compare it to! Flavor is super solid! Mixed Berry is where it's at. Honestly hard not to wanna down more than the recommended dosage. I did as the bottle suggests for the most part, 3oz. 2X a day. Usually took one dose in the morning and one dose before a workout. Around the last week I up'd it to 4oz. ( about spilling out of the cap ) for the remainder of the bottle. Didn't notice just a huge difference so. As far as effectiveness, I seemed to have a bit more energy. I did seem to sweat substantially more. I usually break a sweat fairly easy but with taking this it was almost instant haha. I didn't seem to notice any substantial fat loss per say, but I felt as if I looked like I didn't carry as much water. Whether or not that attributed to sweating my #@@ off I don't know, and I usually take in around a gallon to 2 of water a day so. Overall, I enjoyed the energy/feels from this stuff! For the price, i'd def pick it up.

This is a great L-Carnitine product. The profile is solid, and the flavor (Mixed Berry) is amazing. I seriously had a hard time not just downing the whole bottle at once. I experienced some fat loss while using this. It wasn't a lot, but it was enough to give me the idea that longer usage would have big benefits. iSatori continues to impress.

Flavor was pretty good. Not used to refrigerating my supplements so that was interesting. In the time I used this i did notice it helped me put on less fat. Not so sure on the losing fat though. The science is definitely there if you research it. Not a bad price either.

This is a solid carnitine product. You get what you are paying for, a pure carnitine supplement. The flavor is absolutely excellent, and coming from iSatori you know it is quality. It is a bit pricier than some other products which is the only reason I may opt for something else, but the product itself is a 10/10. Definitely a great weapon to add to your fat loss arsenal. Good job team iSatori.
