Below we take an in-depth look to see just how effective GNC Total Lean Thermo CLA really is at aiding weight loss.
GNC Total Lean Thermo CLA boosts thermogenesis, increases energy levels and supports the metabolism of the consumer. Whilst the main ingredient of Thermo CLA is Conjugated Linoleic Acid (CLA), unlike many other CLA products it also contains a variety of other active ingredients designed to increase calorie burn in the body.
GNC Total Lean Thermo CLA is a part of the Total Lean range of fat burning and weight loss products that is manufactured directly for GNC. GNC, which stands for General Nutrition Company, is an American supplement store that sells products both online and in GNC stores across the nation. GNC can be contacted using the information on their website. They also have a number of stores across the USA, where members of staff should be able to help customers with any queries they have.
As a dietary supplement, take two softgel capsules once or twice daily. Do not take before bedtime.
GNC provide the following description of GNC Total Lean Thermo CLA:
The ingredients for GNC Total Lean Thermo CLA are listed below. The ingredient quantities provided are per two capsule serving. Consumers are advised to take up to two servings per day.
Green tea contains a range of polyphenols, including a sub-group called catechins, which clinical trials have focused upon. One study found that participants who drank beverages high in catechins extracted from green tea (690 mg/d) lost significantly more weight and body fat than those who drank beverages low in catechins (22 mg/d).
Green tea also contains naturally occurring caffeine. Caffeine is also present as a separate ingredient; it will increase energy levels and potentially cause a slight increase to the body’s metabolic rate for a few hours after consumption.
Whilst CLA has shown positive results in studies in rats and mice, aiding significant weight loss and acting as a fat burner, the clinical results in humans are much more varied. Some human clinical trials showed significant fat loss, improved body composition and even increases in muscle mass. However, other studies found no results or changes at all.
One review paper that pooled the results of 18 studies of CLA found that, on average, CLA caused ‘modest’ fat loss. Other reviews describe it as a relatively poor and unreliable fat burner. It may help to retain muscle mass whilst losing weight.
The dose of CLA provided per daily serving is 3000 mg, which falls on the lower end of quantities used in clinical trials. Similarly, the dose of L-Carnitine is much lower than experts recommend for building muscle and treating fatigue. However, CLA and L-Carnitine are arguably the two least effective ingredients in this product. Both CLA and L-Carnitine are most beneficial for individuals who exercise regularly and who are trying to build strength and muscle. L-Carnitine reduces fatigue after strenuous exercise, and also helps to speed up recovery from exercise, with studies showing less muscle damage, including less muscle soreness, when taking L-carnitine than the exerciser would feel without supplementation.
GNC Total Lean Thermo CLA contains caffeine as a separate ingredient, but also contains green tea, which may contain some additional, naturally occurring caffeine. Consuming caffeine can cause side effects such as headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness and insomnia. Green tea can also cause constipation.
There are some potential side effects associated with the use of CLA. It can cause stomach upset, diarrhoea, nausea and fatigue. CLA can also increase triglyceride levels in some cases.
Supplementation of L-carnitine can lead to side effects such as nausea, vomiting, stomach upset, heartburn, diarrhoea, and seizures. According to WebMD, it can also cause the urine, breath, and sweat to have a “fishy” odour.
For adult use only. Do not use this product if you are pregnant or lactating. If you are taking medication or have a medical condition, consult a physician before using this product. Discontinue use two weeks prior to surgery. Not suitable for anyone who may be sensitive to caffeine and other stimulants. Not suitable for anyone who has any heart related health issues, including but not limited to high blood pressure.
There are numerous customer reviews for Thermo CLA. The majority of the reviews are positive, but some people saw no results whilst using the product.
Did not work for me.I started taking these pills a week ago. I haventlost any weight, nor have I seen any changes. I work out 4 days a week at the gym. I have noticed that I am less hungry, only because of my stomach being upset from taking these pills. I have not had that boost of energy everyone is talking about. As a matter of fact, I feel tired and dizzy. These pills also gave me a lot of gas. Very disappointed and will seek a refund.
I have been working out regularly and not seeing results. I will be the first to admit that my diet is the problem area. I was looking for something to boost my fat-burn, metabolism, or whatever that would help me lose weight! I took this for 10 days, also with Garcinia Cambogia. It gave me an energy boost much the same way caffeine does. I do felt it curbed my appetite during the day, but you’re not supposed to take it at night so you can sleep—well, that’s when I would snack. I lost about a pound, but in the end, I can’t say that I thought it was doing much for me so I returned it. Thankfully GNC doesn’t give you any grief about taking products back. For about $1/day, I would expect to see better results.
Not good, not horrible… I didn’t find this product to really help with weight loss or appetite suppression. I’ve been an OxyElite Pro user and definitely prefer that over the Thermo CLA.
Best Product in the GNC Total Lean line!
I made a resolution this year to get fit and healthy. So, in January I started a workout regimen and sensible diet. I have a lot of midsection weight so, I wanted to get rid of that and drop sizes without taking a diet aid like Hydrocut. I went to my local GNC and told the assistant manager what I was looking for. He recommended CLA complex. I have been using it since January and in combination with my daily workout routine + healthy diet I have dropped 10 inches from my waist. I just recently switched over to Thermo CLA and I already see a bit more improvement in one week. There is more tone in my midsection and less accumulation of fat. I have never felt better and I would recommend this product to anyone looking to add a weight loss aid to their exercise and diet routine.
I have been using CLA for a little over a week now and I love it!!! It gives me a lot of energy and it decreases my appetite. Within the past week I have lost 3 pounds!!! So I can truly say that it works. All I can say is…..I am a very satisfied customer!!!!
Green tea is effective as a thermogenic, but its results are still described by researchers as ‘small but significant’. The quantities used in Thermo CLA are far less than those used in successful clinical trials, especially concerning the catechin content of the extract.
CLA does appear to have some effect upon the body, somewhat reducing fat mass and aiding muscle growth in consumers who are exercising regularly in order to build muscle. It may not result in weight loss overall, but as it may aid muscle growth, it could therefore indirectly boost the body’s metabolic rate. There is also the worry that it is an unreliable or unpredictable supplement. Studies report vastly different effects upon the body, with some noting no changes at all.
L-Carnitine is often hyped up as a fat burner, but in reality this is a massive overstatement; studies show no fat burning in teenagers and adults under the age of around 55 to 60. The strongest fat burning results have been seen in the elderly only.
Overall, there is some evidence that some of the ingredients could aid weight loss, although it seems that some ingredients are more consistent in their effects than others. For anyone who has seen benefits from the very unreliable CLA in the past, this product could be a good CLA supplement that provides extra benefits from its other metabolism boosting ingredients. However, there may be others who lose no weight at all whilst consuming the product.
GNC Total Lean Thermo CLA can be purchased from the GNC official website or any GNC retail store. A single bottle of 90 tablets costs $32.99. Customers who are GNC members will pay a reduced price of $28.99.
Members are people who have purchased an annual GNC gold membership card at a price of $15.00 per year, which grants them additional discounts on many of the products available at GNC. This may be a good investment for those who shop at GNC regularly, but for many the cost of the membership would outweigh savings made on just a few purchases over the course of the year. Shipping costs on all deliveries is a flat rate of $3.99.
GNC Total Lean Thermo CLA can also be purchased from amazon, where a single bottle costs $22.09 plus delivery.
Recommended daily use is between two and four capsules per day. This means that a single bottle of 90 capsules will last between 22 and 45 days.
GNC offer a 30 day money back guarantee on unopened and unused products, minus the cost of shipping. This is valid from the date of the order.
Overall, whilst GNC Total Lean Thermo CLA could aid a small amount of weight loss thanks to its caffeine and green tea content, we are still not convinced that CLA supplements are the best way to aid weight loss. CLA is an unreliable and unpredictable fat burner, at best providing modest weight loss, and its benefits are overhyped. L-carnitine is another ingredient that is overhyped, as only aids fat burning in the elderly, and yet is often promoted as a fat burner for all. GNC Total Lean Thermo CLA is probably going to benefit those who are exercising and trying to gain muscle mass as well as lose fat mass the most. Some of the ingredient quantities are less than ideal; the quantities of L-carnitine, CLA and green tea used in this product are less than those used in successful clinical trials.
GNC offer a 30 day money back guarantee, but this only covers unopened and unused products, and so cannot really be called a full guarantee.
Whilst most CLA supplements can be stacked with other weight loss aids, GNC Total Lean Thermo CLA should be taken on its own, as it already contains stimulant ingredients.
Overall, we do not recommend GNC Total Lean Thermo CLA to our readers, as the potential results that studies suggest are far from guaranteed, with unreliable ingredients used in less than adequate quantities.
