CLA (Conjugated Linoleic Acid) is a naturally occurring, polyunsaturated fatty acid found in the meat of ruminants (cows, sheep, etc.) and dairy from these animals. It is formed in the rumen of grazing cattle in a process where linoleic acid from grass is transformed into CLA.
About green tea
Green tea extract is particularly popular among dieters. It has a high content of the active compound epigallocatechin gallate (EGCG). Natural green tea extract with EGCG helps to enhance metabolism and contributes to fat oxidation.
Why do we need to supplement?
CLA has been explored in a wide range of body composition trials, with evidence showing that it may increase lean muscle and decrease body fat storage. The most important aspect of weight is how it is distributed. Muscle weighs more than stored fat (adipose), so someone with a high lean muscle may weight the same as someone with lower lean muscle, but will appear much leaner.
How does it work in the body?
A CLA supplement with green tea extract can support your body’s fat oxidation and enhance your metabolism.
CLA contains a mixture of different naturally occurring chemical shapes, known as isomers which have slightly different effects. The two main CLA isomers shown to have health benefits are c9t11 (cis-9, trans-11) and t10c12 (trans-10, cis-12) associated with general health and body fat reduction respectively.
The main way CLA is shown to work in the body is in the activation of Peroxisome Proliferator activated Receptor alpha (PPARa), a protein found in high levels in the liver. PPARA’s major function is to regulate the metabolism of fats in the liver.
Green Tea extract can inhibit absorption of fat from the digestive tract, reduce blood lipid levels, activate fat burning and increase energy expenditure, according to clinical trials. Green Tea is also high in flavonoids and catechins, offering a powerful antioxidant defence.
Benefits in research
CLA supplementation may contribute to fat loss, according to several clinical trials. The additional mechanism proposed for this is the suppression of fat-gaining enzymes, including fatty acid synthase 1.
In one study, participants who supplemented with CLA over 6 months saw a significant reduction in body weight when compared to those taking placebos 2.
Green tea also demonstrates strong potential for weight loss. In a meta-analysis of studies, it was found that green tea significantly contributes to the reduction of body weight. The proposed component in green tea associated with this reduction was a family of plant compounds known as catechins 3.
Lean muscle mass
CLA supplementation may also support the increase of lean muscle mass. In one example study, CLA supplementation ( when compared to fish oil as a control ) was able to increase lean muscle mass in individuals by 2.4% (over 12 weeks) 4.
The mechanism behind this isn’t fully understood, but it’s proposed that CLA may alter the way muscle fibres behave or altering the muscle’s metabolism 5.
Bio-CLA + Green tea
Bio-CLA + Green tea is a double action product blending the evidence-based benefits of two effective compounds. The product has won several international prizes in European consumer and retail events aimed at selecting the best preparations in categories such as “Weight Management”.
Bio-CLA + Green tea contains conjugated linoleic acid of the types t10,c12 & c9,t11 in a 1:1 ratio. These isomers are considered the most well documented and important to human health.
In our diet, fats occur as triglycerides that must be broken down to "free" fatty acids before the digestive tract is able to absorb them. This process is enabled by a digestive enzyme called lipase. Bio-CLA + Green tea contains conjugated linoleic acid in the form of free fatty acids that have already been broken down and are ready for use. The advantage with this type of fatty acids is that they can be absorbed directly even by individuals with impaired lipid absorption.
