5 out of 5 stars from 23 reviews

L-Carnitine L-Tartrate is a great choice for athletes and bodybuilders alike, assisting with greater improvements in fat loss, performance and recovery.

Various studies suggest that L-Carnitine L-Tartrate may improve aerobic performance and also increase recovery, making it a good choice for those looking to improve body composition as well as increase aerobic performance and recovery. In summary, various studies suggest it may assist in:

  • Combining L-Carnitine with L-Tartrate improves Carnitine absorption
  • Transports fat to be burned in the mitochondria
  • Preserves and spares Glycogen for improved energy reserves (Bucioli S et al, 2012)
  • Reduces muscle lactate buildup for improved endurance and performance (Wall B et al, 2011)
  • Faster recovery times
  • Decreases oxidative stress and inflammation caused by intense workouts (Bucioli S et al, 2012)
  • Improves aerobic performance

L-Carnitine is a nitrogen-containing compound derived from L-Lysine & Methionine. L-Tartrate is a powerful antioxidant that has been attached to L-Carnitine to improve carnitine absorption.

L-Carnitine L-Tartrate has been shown to be more bio-available and faster absorbed than other forms of L-Carnitine (Eder K et al, 2005).

The carnitine molecule works by transporting fat (long-chain fatty acids) into the mitochondria (our energy generators) so they can be burned – hence the term fat burning. This produces the energy rich ATP.

Once the energy is burned, carnitine transports the toxic compounds back out of the mitochondria. L-Carnitine is thus essential for the supply of energy to the muscles.

Gluten free and suitable for vegans.

I have this prior to my gym session mixed with creatine on a regular basis. Find it helps during a session and after for recovery...

I purchased L-carnitine L-tartrate a couple of weeks ago and was amazed at how much more energy I had and endurance whilst doing my workout. I found that I could increase my weights easier than without taking this wonderful product. Taking a dose 15-30 mins before starting, and immediately afterwards, kept my energy levels up. It has an unusual smell but tastes ok. I definitely recommend this for anyone who wants to workout with peak performance. Also, I'm new to taking any of this type of product or supplement and I'm so happy I have. Great quality. Great performance. Natural.

Excellent for shedding unwanted fat

Highly recommend this product and wouldn’t be purchasing anywhere else. Since I’ve started taking this supplement, I have seen massive changes with my body. I will keep repurchasing this product and the most amazing part about it is It’s pure without any artificial flavours and Supper affordable. Thank you for the amazing product.

Unexpected Necessity

By: on 23 May 2017
I got started on this product to help with my bikini competition prep, I'd never heard of it before my coach recommended it but now that I've been using it for a while I wonder how I went without. It's seriously helped with my body composition and burning fat, alongside that it helps me go into my workouts focused and after working out helps my muscles recover faster so I'm actually able to function the next day at work after a killer workout. Definitely recommend.

Using just small dose for about a month, I've found myself with more energy and endurance during the day and my workouts. I've definitely noticed fat loss. Sure, the stuff smells pretty rank in the bag (so try not to sniff the bag), but it has a lemony flavour that I quite like. The only downside I've experienced is that it gives me constipation at a higher dosage, easily managed by decreasing the dose and increasing fibre and water intake.

Lost without it

I'm so glad I've caught onto professional whey's L caritine product. I train intensely 6 days a week. I always have and alway will but this product has given me the edge I've been looking for. My recovery times are low. My fat metabolisation is high. I have this 3 times a day and I'm set. Nothing stops me and results just keep coming. This added into a balanced diet will push you over the line and renew your passion for working out and seeing results. About to order some more!

Great product

I had plateaued with my weight loss but this product helped me lose the last couple % of body fat. I also felt like I had more energy whilst working out


By: on 29 July 2015
I originally took this product not for it's fat loss properties, but to help aid my recovery and mental focus. It definitely has helped my recovery and I have lost a bit of weight since I've been on it. But I'm not sure if it was due to the product, the training or both.

Actual results

By: on 16 January 2014
I hit a bit of a wall with my fat loss, despite sticking to my caloric goals. Taking this twice daily (upon waking up and with lunch) has helped me break through that plateau and am seeing some serious vascularity. A little pricey, but totally worth it. Smells a bit odd, but has a pleasant lemon taste when mixed with water. Tastes awful with any kind of whey protein.

A great product

By: on 15 January 2014
A great product at an even better price. Taking this twice per day has helped me with my focus and fat loss efforts. The taste is pallatable and not as potent as other Lcarnitine brands. Another great product by professional whey with a very prompt customer service team and delivery times - there is nothing to fault here at all! I would love to see a small scoop include in the bag OR available for purchase.

Great Taste!

By: on 4 January 2014
Although this stuff stinks, it has a pleasant fruity taste. I just mix in water and it's easy to drink, fully dissolves. Early days for me so can't attest to results, but I am confident in Professional Whey's products.

Essential for Cutting!

By: on 3 January 2014
I found this a great help for me to lose that little extra fat combined with an appropriate diet/cardio/weight training when cutting. dont be mislead when you open your package! its a small bag but great value for money with 100 serves!

No placebo effect here, this is the real stuff

By: on 1 November 2013
I have taken the Carnitine on (for 4~6wks at a time) and off (again for 4~6wks), several times just to compare and confirm results in a controlled manner. I take it 1~2g in the morning first thing when i wake up, and in the afternoon before a work out. when I'm on it, the same gym routine work outs becomes noticeably easier, especially cardio work outs - recovery time for resistance/weights becomes shorter and overall fitness levels feels better all round compared to when I'm off it. I'm at the lightest weight I have been in the last 10 years and keen to see how much further I can push with this great product. taste is ok, but just gulp it down and wash it down with another glass of water, dont even stress it :P

Totally Surprised Me

By: on 22 October 2013
Palatable was nice but I consistently feel a difference both when I work out and for the rest of the day. Top product.

Morning routine

By: on 16 September 2013
I have been using this product for approx 8wks now and have definitely achieved results. I add it to my morning glass of water and fresh squeeze of lemon. PROFESSIONAL WHEY is a favourite brand of mine

Great improvement!

By: on 6 September 2013
Been taking L-Carnitine for a couple of months now to get a little less body fat percentage and i can honestly say that this product has worked for me.I will keep using this product and have gotten a few of my friends on it too with some success in a short period.Very happy!!!!!

Amazing Result!!!!!

By: on 19 August 2013
Great product!!! i will never achieved 20 kg weight loss!!! amazing result, early morning just it works perfect, good taste and no heart burn like these tablets from the chemist. I will buy definitely more because i finally find something that work!

Great tasting FAT KILLER!

By: on 7 July 2013
I've recently bought 2 X 250g packets of L-Carnitine L-Tartrate after doing some research regarding the issue of FAT LOSS. I've also started doing some gym work targeting muscle mass. The idea is to rid my body of excessive fat thus expediting visible muscle gain...it tastes great (fruity flavor) and I drink it as a stand alone product although it can be mixed with protein powders. I mix 5g of L-Carnitine L-Tartrate with 100ml water drinking the solution before and after a gym workout. My wife also uses L-Carnitine L-Tartrate purely for weight loss purposes, she drinks 5g of L-Carnitine L-Tartrate with 100ml water before and during her cardio exercises.

Helps shred !!

Works great in helping me lose fat !


By: on 11 December 2012
I believe Professional Whey supply quality product in no nonsense packaging. This is another example. Early days yet but I notice a slight change in my endurance. Can't attest to the fat burning ability yet but we will see. It is an acquired taste but would give it a second look.

Another great product!

By: on 24 May 2012
Another quality product from the team at Professional Whey. Easily the best value, best tasting Carnitine i've used, and it has helped me to shed those last few stubborn kilos. I will definitely be buying this one again!
