LG Sciences C2K Review

LG Sciences C2K Facts

  • Manufactured by LG Sciences
  • 120 servings per bottle- 30 day supply
  • Liquid product for increased absorption into bloodstream

C2K is a thermogenic weight loss aid manufactured by LG Sciences. Its liquid composition is intended to make it more bioavailable, and hence much more effective even in low doses.

The LG Sciences website has a contact form at the bottom of each page, making it fairly easy to contact them. There is surprisingly little contact information available, although there are links to their Facebook and Twitter. Luckily, their Facebook page provides slightly more information, including a phone number (+1 810-599-9402) and an email address.

When we contacted LG Sciences through Facebook asking about the returns policy, they replied within a few hours, which even more impressive considering this was during the weekend. They had presumed that we were a current customer, and also asked what was wrong. When our researcher stated that she was still trying to decide what to buy, they asked what product she was looking at and were more than happy to help.

An FDA report revealed that LG Sciences are based in Brighton, Michigan, but also revealed that the company had huge amounts of stock confiscated back in 2008 for failing to adhere to FDA guidelines, and manufacturing several different products that contained banned ingredients.

How to Take LG Sciences C2K

Shake well.

Snap down the syringe dispenser or use the dropper.

Dispense 1.5ml under the tongue for 60 seconds, then swish the content around your mouth and swallow completely.

Use 4 doses spread out during the day with at least 30 minutes between doses or whenever you feel hungry.

Doses can be taken any time of the day but are best spaced out as far as possible.

Consumers are instructed to cycle the product, using the product for 8 weeks before taking a four week break, and repeating as necessary.

What does concern us about this product is the huge legal disclaimer printed on the bottle. Disclaimers such as these are fairly standard on product websites, but the fact that the company feels the need to print this on the bottle makes us wonder how worried they are about potential law suits:

By purchasing this product you agree: (1) all disputes, claims, and causes of action arising out of or in connection with this product shall be resolved individually, without resort to any form of class action, by binding arbitration to take place in Detroit, MI pursuant to the rules of the American Arbitration Association; (2) all claims, judgments, and awards shall be limited to the actual out-of-pocket amount paid by you to LG Supplements LLC. to purchase the product, but in no event attorney’s fees; and (3) under no circumstances will you be allowed to obtain awards for, and you hereby waive all rights to claim punitive, incidental, or consequential damages, any other damages other than actual out-of-pocket expenses, and all rights to have damages multiplied or otherwise increased. A judgment of any circuit court may be rendered upon the arbitration award made pursuant to this agreement. The construction, validity, interpretation and enforceability of this agreement, or the rights and obligations of users and us in connection with this product, shall be governed by and construed in accordance with the laws of Michigan, without giving effect to any choice of law or conflict of law rules or provisions (whether of MI or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the Michigan. If any of these terms are found unlawful, void, or for any reason unenforceable, the provision will be considered severable from the remaining terms, and will not affect the validity and enforceability of the remaining provisions.

LG Sciences C2K Concerns:

  • Website does not explain how all ingredients work
  • No ingredient quantities
  • Length of the money-back guarantee?

What Does LG Sciences C2K Claim To Do?

LG Sciences claim that this is a thermogenic weight loss aid, but do note that all claims made are dependent upon the consumer also undertaking a proper diet and regular exercise.

The website states:

Use this potent combination to help supercharge your diet and exercise program. Oral dosing under the tongue with plant extracts like chlorogenic acid found in green coffee and raspberry ketones has been shown in one preliminary study to be up to 250X more bioavailable than oral capsules. This means that it is possible that 5 mg of raspberry ketones in our unique delivery system may be equal to 1250mg of a capsule based product!

So What Is LG Sciences C2K and What Are The Ingredients For LG Sciences C2K?

The main three ingredients used in C2K are a proprietary blend. No ingredient quantities are provided.

  • L-Carnitine, L-Tartrate: Supplementation of this ingredient has been found to improve fat oxidation in some studies, whilst it has shown no effects in other studies. Also known to improve athletic performance and to reduce fatigue, improving recovery time. Greatest results were seen with doses of 2 grams per day.
  • Chlorogenic Acid (from Green Coffee Bean and Eucommia U.): Chlorogenic acid has been shown to increase weight loss in numerous studies. However, many of the trials were heavily influenced or funded by manufacturers of diet pill supplements. Studies suggest that chlorogenic acid has little effect upon those who are already within a healthy weight range.
  • Raspberry Ketones: Raspberry ketone is the part of a raspberry (and other fruits) that provides the distinctive smell of raspberries. Whilst it can be extracted from the fruit, especially for use in food flavourings and perfume production, it is much cheaper to synthesize it in a lab, especially for the large quantities that are required for use in raspberry ketone supplements. Whilst there is a small amount of evidence that raspberry ketone can cause weight loss in rats, there have never been any human trials on the potential weight loss effects of raspberry ketone. The safety of using such large quantities of raspberry ketone has also never been fully researched.

Other Ingredients: Water, Glycerol, HPBCD, Citric Acid, Na Benzoate, Ca EDTA, K Sorbate, N&A Flavor, Sucralose, Ace K, Stevia. Xanthin Gum.

Sucralose, Ace K and Stevia are sweeteners. Na Benzoate and K Sorbate are food preservatives. HPBCD binds with cholesterol, allowing it to be removed from the bloodstream more easily by the body. Ca EDTA is typically used to treat lead poisoning, and its purpose in this diet pill is unclear.

So What Does All This Mean?

Green coffee bean extract has been proven to boost the metabolism and increase weight loss, and is considered a good ingredient to have in a diet pill.

Raspberry Ketone, on the other hand, has never been researched in humans, and has been classed as a novelty product in the EU, because of this lack of research. L-Carnitine can increase fat oxidation in some groups of people, but the doses required to duplicate studies are unlikely to be present in this product, as most studies use a dose of 2 grams per day.

Does LG Sciences C2K Have Any Side Effects?

Because of the various ingredients used in C2K, it is possible that various different side effects could occur. The bottle warns consumers that potential side effects include,

acne, hair loss, hair growth on the face (in women), aggressiveness, irritability, and increased levels of oestrogen.

Chlorogenic acid and Raspberry ketones are still relatively under-researched in terms of their side effects, and so no serious side effects have been reported at this time.

However, it is possible that they are merely undiscovered, rather than non-existent.

L-Carnitine can cause side effects such as nausea, vomiting, heartburn, stomach upset, diarrhoea, and seizures. It can also cause the urine, breath, and sweat to have a ‘fishy’ smell, although this is more likely when it is taken in much higher doses than are found in C2K.

The following warning message is detailed on the official product website.



Consult a physician or licensed qualified health care professional before using this product if you have, or have a family history of, prostate cancer, prostate enlargement, heart disease, low “good” cholesterol (HDL), or if you are using any other dietary supplement, prescription drug, or over the counter drug.

Do not exceed recommended serving. Exceeding recommended serving may cause serious adverse health effects.

Possible side effects include acne, hair loss, hair growth on the face (in women), aggressiveness, irritability, and increased levels of oestrogen. Discontinue use and call a physician or licensed qualified health care professional immediately if you experience rapid heart beat, dizziness, blurred vision, or other similar symptoms. Made in a facility that may process dairy, peanuts, tree nuts, wheat, fish, barley and shellfish. Do not use if governed by anybody that prohibits hormone use.

Any LG Sciences C2K Reviews From Customers?

There are two customer reviews on the official website:

Great for kicking the metabolism into overdrive. It’s like I am a walking furnace right now. My hunger is under control, I was always walking around hungry but now not so.

I have had the trouble in the past always being hungry and snacking a lot, but once I started using this product it has boosted my metabolism and helped stop my hunger cravings. I have extra boost of energy when I do my cardio sessions and i feel great afterwards! I definitely recommend this product to everyone and anyone.

Whilst C2K is also sold on, and has been sold by in the past, there are no customer reviews on either of these websites. sells C2K, and has some positive customer reviews:

This is the best non stim thermo on the market. I have a log on forum under the LG Q and A (C2K log). The effects were amazing and I took the recommended dosage 4x’s a day. When I would train I would sweat more than usual and could tell it was working. I have before and after pics to show the results.

I am very picky about what I put into my body, BUT I was getting ready to do a cut, and I stumbled across this product. The ingredients looked great and GUESS WHAT, it WORKED. It wasn’t one of those caffeine highs that you usually get, but this one WORKED GREAT.

I started this product last week as part of my contest prep and have already dropped another 5lbs and couple % of body fat with its help. Just 4 droppers a day so very simple and tastes really great too. Thermogenic aid it is so claim fits the title.

These reviews are all posted by consumers who have clearly been pairing the drops with intensive exercise, and so consumers who do not exercise should not expect such dramatic results.

So Does LG Sciences C2K Work?

The product website states that,

The liquid delivery system gives you immediate absorption in the mouth and then prolonged absorption through the digestive tract. This allows for better bio-availability and more immediate action in the body.

Whilst this may mean that the much smaller doses of active ingredients are still effective as they are absorbed into the bloodstream effectively, we do not believe that C2K is a very effective weight loss aid. One of the main ingredients, raspberry ketone has never been tested in humans, and there is no recommended dose for this ingredient.

L-Carnitine may have an effect upon weight loss, but when used in much larger quantities than found here. Chlorogenic acid seems to be the only ingredient that is likely to contribute to weight loss, but as we do not know the quantities used, we consider it unlikely. Consumers of coffee are going to consume more chlorogenic acid from their cups of coffee than they are going to receive from the few drops of this product consumed per day.

On the other hand, customer reviews are overwhelmingly positive, especially when the use of this product is combined with intensive exercise.

Where Can I Buy LG Sciences C2K?

Each bottle of C2K costs $35.99 plus delivery, reduced from $59.99, when purchased from lgsciences. The product is also available on, at a price of £22.95 per bottle, with free UK delivery, or from, at $29.46 per bottle with $4.99 shipping.

What About A Guarantee

Although the official website does not mention the company’s returns policy, when we contacted LG Sciences through Facebook, posing as a potential customer, they stated that they had a 100% satisfaction guarantee. Customers need to contact the company to arrange a refund.

Watchdog Verdict

We have mixed opinions when it comes to C2K. On the one hand, the customer reviews are overwhelmingly positive, leading us to conclude that this supplement can aid weight loss when combined with regular and intensive exercise.

However, the product comes with a long list of warnings, especially about the possible side effects that could occur. One of the main ingredients, raspberry ketone, has never been tested in humans, and animal studies are only preliminary.

Chlorogenic acid may aid weight loss, and L-Carnitine may improve fat oxidation, but it seems that healthy people in the normal weight range are not affected by either ingredient much.

There is no information on the LG sciences website about their returns policy or their location, although a company representative assured us that there was a 100% satisfaction guarantee, although he failed to mention how long this guarantee was valid for.

With insufficient clinical evidence to support the entire ingredients profile, a lack of ingredient quantities, and the lack of information provided freely by LG Sciences, we cannot approve C2K as a viable weight loss supplement.

We reject LG Sciences C2K.
