Tonalin - CLA (conjugated linoleic acid)

Decades of research indicate that CLA (conjugated linoleic acid) actually changes body composition by reducing body fat and increasing or preserving lean muscle mass—giving you a leaner, healthier appearance.

Studies found that 3.4 grams of CLA was needed in order to get the benefits. That's 3,400 mg. Since the various formulas contain a percentage of other oils as ingredients, it's wise to probably calculate how much each pill is delivering to make sure you're getting the full 3.4 grams a day. For example, if your capsule contains 75% CLA, and it's 1000 mg, then you're getting 750 mg of CLA, and would need 5 per day to get to the 3.4 grams level. There are only a few brands that offer this measurement including:Diet Lean Body Fat Regulator, Tonalin CLA and Chromium,> Natrol Tonalin CLA Softgels> , and  Source Naturals Tonalin 1000 CLA Softgels.

Dr. Michael Pariza, who conducted research on CLA with the University of Wisconsin-Madison, reported in August 2000 to the American Chemical Society that "It doesn't make a big fat cell get little. What it rather does is keep a little fat cell from getting big." Pariza's research did not find weight loss in his group of 71 overweight people, but what he did find was that when the dieters stopped dieting, and gained back weight, those taking CLA "were more likely to gain muscle and not fat.'' In a separate study conducted at Purdue University in Indiana, CLA was found to improve insulin levels in about two-thirds of diabetic patients, and moderately reduced the blood glucose level and triglyceride levels.

CLA has been the subject of a variety of research in the past several years, and findings also suggest that some of the other benefits of CLA include the following:

     Increases metabolic rate-- This would obviously be a positive benefit for persons with low metabolic rates.
     Decreases abdominal fat
-- Hormonal shifts such as those related to PMS and menopause or persons suffering from acute stress, frequently cause rapid accumulation of abdominal fat, so this benefit could be quite helpful.
     Enhances muscle growth
-- Muscle burns fat, which also contributes to increased metabolism, which is useful in weight loss and management.
     Lowers cholesterol and triglycerides
-- Since many overweight persons have elevated cholesterol and triglyceride levels, even with treatment, this benefit may have an impact on a persons health.
     Lowers insulin resistance
--  Lowering it can also help prevent adult-onset diabetes and make it easier to control weight.
     Reduces food-induced allergic reactions
-- Since food allergies can be at play when weight loss becomes difficult, this can be of help.
     Enhances immune system
-- Enhancing the immune system's ability to function properly is a positive benefit.

If you're interested in taking CLA to help with weight loss, keep in mind that it's not a magic pill, and you will need to start a program of diet and exercise in order to successfully lose weight and keep it off.

There's no evidence that CLA, a food supplement, interacts with medications, or poses any special dangers. But you should always discuss any supplements you intend to take with your own physician or practitioner before starting.

Some people report feeling slightly green or nauseous after taking their CLA, or isolated cases of gastrointestinal upset or loose stools. These side effects typically are reduced when the product is taken with protein (i.e.,with milk), and usually decrease after about 2 weeks taking the supplement.



STUDIES INCLUDE:

"Conjugated Linoleic Acid Reduces Body Fat in Healthy Exercising Humans"
Institution:Journal of International Medical Research
Description:
Volunteers received CLA or placebo for 3 months, and asked not to make any changes in their diet and lifestyle during the study.

"Conjugated linoleic acid (CLA) reduced abdominal adipose tissue in obese middle-aged men with signs of the metabolic syndrome: a randomised controlled trial."
Institution:
International Journal of Obesity
Results
: The CLA group had a significant reduction in body fat percent from 21.3% to 17.0%, and a reduction in body weight (from 69.6 to 68.9 kg).
Description:Volunteers received CLA or placebo for 4 weeks, and did not make changes in their diet and lifestyle during the study.
Results:The CLA group had a significant decrease in abdominal diameter, an average of one inch from their waistlines.

"Conjugated linoleic acid supplementation for 1 year reduces body fat mass in healthy overweight humans"
Institution:
 American Society of Clinical Nutrition
Description: 
Overweight volunteers received CLA each day over 1 year or received a placebo (control group) per day.
Results:
 Mean body fat mass in the CLA groups was 6.9% - 8.7% lower than that in the placebo-control group. Long-term supplementation with CLA reduced body fat mass in healthy overweight adults.

"Supplementation with Conjugated Linoleic Acid for 24 Months Is Well Tolerated by and Reduces Body Fat Mass in Healthy, Overweight Humans"
Institution: 
Journal of Nutrition
Description:
 Follow-up of 12 month placebo-controlled study. Moderately overweight volunteers received CLA each day.
Results: 
Subjects who lost body fat mass in year one of the study could keep their body fat off, and subjects who previously had received placebo and were switched to CLA, now lost body fat mass significantly. Leptin levels decreased over the whole period of supplementation by more than 20%. Long-term supplementation with CLA is safe over 24 months at least.

"The Effects of Conjugated Linoleic Acid Supplementation during Resistance Training"
Institution: 
American College of Sports Medicine (2006)
Description:
 Healthy men and women received CLA or placebo while participating in a total-body resistance-training program for a 7-week period. Measurements, before and shortly after completion of the study, included total body weight, precent body fat, lean body mass, fat mass and muscle thickness.
Results: 
AAfter 7 weeks, the CLA group had greater increases in lean tissue mass and greater losses of fat mass and percent fat compared with the placebo group. Additionally, the resting metabolic rate (RMR) remained constant in the CLA group, while RMR decreased in the placebo group.

"The role of conjugated linoleic acid in reducing body fat and preventing holiday weight gain"
Institution: 
International Journal of Obesity (2006)
Description:
 Forty healthy, overweight men and women between the ages of 18-44 years with a body mass index between 25-30 kg/m2> received CLA or placebo during a 6 month period. Body weight was measured monthly during the pre-holiday season (August-December), holiday season (November-December) and post-holiday season (January-March).
Results:  
Compared to CLA, the placebo group showed a greater rate of weight gain during the holiday season.  Within the placebo group, holiday weight change was significantly greater compared to the pre-holiday period.  Six-month change in body composition was improved with CLA compared to placebo, and body fat was significantly reduced within the CLA group.

CLA is a supplement, and does not require a prescription. Please note also, that you should not think that CLA alone will help you lose weight. You still need to be on a balanced, reduced-calorie, low-glycemic diet, and have to incorporate regular, vigorous exercise, and weight bearing activities, into your life Studies found that 3.4 grams of CLA was needed in order to get the benefits. That's 3,400 mg. Since the various formulas contain a percentage of other oils as ingredients, it's wise to probably calculate how much each pill is delivering to make sure you're getting the full 3.4 grams a day. For example, if your capsule contains 75% CLA, and it's 1000 mg, then you're getting 750 mg of CLA, and would need 5 per day to get to the 3.4 grams level.
