Below we take an in-depth look to see how effective MET-Rx CLA Tonalin 1000 is at aiding weight loss.
MET-Rx CLA Tonalin 1000 is a CLA supplement that, according to the manufacturers, will ‘support your body-shaping goals’ by modulating oxidative enzyme activity as well as energy metabolism. The product is intended for elite athletes, bodybuilders, and anyone striving to get into peak condition; it is not intended for anyone who is not undertaking regular intensive exercise, and is not designed to aid huge amounts of fat loss. The product is a non-stimulant.
MET-Rx CLA Tonalin 1000 is manufactured by MET-Rx, an American company based in New York who have been in business for around 20 years. The company has several international offices, and contact details for all of them are available on the official MET-Rx website. The same contact us webpage also has details for all of the International MET-Rx distributers, organised by region.
Use in conjunction with an intense daily exercise program and a balanced diet including an adequate caloric intake. For adults, take one (1) softgel four times daily, preferably with meals.
MET-Rx describes their CLA supplement as follows:
MET-Rx CLA Tonalin 1000 is an advanced supplement designed for elite athletes, bodybuilders, and anyone striving to get into peak condition. CLA, or conjugated linoleic acid, is believed to work by modulating oxidative enzyme activity as well as energy metabolism. * It is derived from all-natural safflower oil and contains no natural or artificial stimulants of any kind. MET-Rx CLA Tonalin is an ideal choice for people sensitive to the effects of caffeine and other thermogenics. Incorporate this product into your intensive training program to support your body-shaping goals.
MET-Rx CLA Tonalin 1000 is a single ingredient supplement; each serving of a single capsule contains 10 calories and 1000mg of Tonalin CLA.
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. Because it is a single ingredient supplement that is non-stimulant, PHD CLA soft gels can be stacked with other products, and can be taken in the evening.
With each capsule containing 1000 mg of CLA, and consumers being instructed to take 4 capsules per day, spread throughout the day, it seems that consumers would be taking a fairly high dose, which is similar to the doses used in clinical trials. Even at this high dose, the product is far from the most effective diet pill we have ever seen.
There are some potential side effects associated with the use of CLA. It can cause stomach upset, diarrhoea, nausea and fatigue.
Not intended for use by pregnant or nursing women. If you are taking any medications, consult your doctor before use. Discontinue use and consult your doctor if any adverse reactions occur. Not intended for use by persons under the age of 18. Keep out of reach of children.
There are numerous reviews for MET-Rx CLA Tonalin 1000 on the many third party websites that sell the product. Whilst the majority of reviews are positive, we were concerned by two reviews that noted huge increases in their triglyceride levels whilst using the product.
My triglycerides were elevated after taking this for three months. My doctor was so alarmed she actually called me after routine blood work to let me know because I’ve historically had absolutely LOW cholesterol and triglycerides – I’m a vegetarian and work out daily, am actually in great shape for a post-menopausal woman (I’m 63, 5’3″ and weigh 122 lbs). Taking this product was the ONLY difference in my diet and exercise routine so I googled “CLA Tonalin impacts triglycerides” and then saw a few studies that noted in some cases it did cause cholesterol to increase. For me, it’s not worth the risk of developing heart disease even if it does slightly help increase muscle — which studies are still mixed on.
Be very careful. Used this 2 months before my regular yearly physical. In the past year I lost 45 lbs with diet and exercise. Started to use this as a plateau boost, 2 months later my bad cholesterol was 50 points higher than the year before after major diet and exercise changes for the better (nothing fried or high in fat) Could this be the cause, will probably never know but use with caution.
Really good CLA… Not much difference with this one and the others i have tried that are much cheaper, but a good product.
I’ve been taking this product for about a month now and truly notice results. My abdominal area is becoming shredded. I am very strict to begin with and maintain a great off-season.. This just gave me that little bit extra.
This product works for me. I switched to a non-Tonalin CLA brand because it was cheaper, and my weight and health steadily declined. I’m now back on this product, and have once again been losing fat. I can’t say for sure there’s a connection, but since every CLA study that shows a positive effect with CLA use uses Tonalin CLA, I won’t be going back.
I’ve been cycling CLA for about two years. First of all, you need to know that you have to use it for AT LEAST 90 days before judging it. Because of the way CLA causes subcutaneous fat loss, it’s a slow process. Taking it for a week or a month doesn’t give it long enough to work. After my first 90 day cycle, I had excellent separation in my front/lateral/rear delts, and my quads had good definition. After three 90 day cycles (1 year with 4 week breaks between cycles), I had excellent inner pec definition with great serratus muscle separation.
CLA won’t get rid of visceral fat and is not a “fat burner”. It fools your body into decreasing fat beneath the skin which lets muscle definition show through. If you’re working out, this will help with definition and sculpting. If you just want to lose belly or butt fat, this is not the supplement for you.
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.
Customer reviews have predominantly been left by consumers who appear to have a high level of fitness, who are looking to improve their physique to expose their muscle tone, rather than lose huge amounts of fat from their body; these are the types of people who MET-Rx CLA Tonalin 1000 will benefit the most; this product is not likely to make any difference to the consumers weight, fat mass or muscle tone if they do not undertake regular intensive exercise and follow a strict diet.
Anyone who has high triglyceride levels should avoid using this product.
MET-Rx CLA Tonalin 1000 is available from numerous third party online retailers, as well as direct from the manufacturer’s official website. From the official MET-Rx website, a single bottle containing 90 capsules costs $27.19. A six pack of bottles costs $116.14 and a 12 pack costs $226.28.
From drugstore.com a single bottle costs $13.89 plus delivery. Vitacost offer a single bottle for $12.99 plus delivery. MET-Rx CLA Tonalin 1000 can also be purchased from bodybuilding.com, with a single bottle costing $13.04 plus delivery.
A single bottle contains 90 capsules; customers are instructed to take four capsules per day, and so a single bottle of MET-Rx CLA Tonalin 1000 will only last for 22 days. So whilst 90 capsules may seem like a lot, they will not even last for a full month, meaning that the cost of using these in the long term is higher than it initially appears, especially if ordering direct from the manufacturer. On balance, if purchasing the product from one of the cheaper third party retailers, this product still offers relatively good value for money.

For anyone who likes CLA products but dislikes powdered products, MET-Rx CLA Tonalin 1000 could potentially be a good option, if the consumer shops around for a good price.
When purchased from the manufacturers, the price of a bottle is relatively expensive, but if customers shop around then they can find a good deal. The product is covered under a 100% satisfaction guarantee when purchased direct from the MET-Rx online shop.
With each capsule containing 1000 mg of CLA, and consumers being instructed to take 4 capsules per day, spread throughout the day, it seems that consumers would be taking a fairly high dose, which is similar to the doses used in clinical trials. Even at this high dose, the product is far from the most effective diet pill we have ever seen. Taking four capsules, spread evenly throughout the day could also be incredibly tiresome, and it could be easy to forget to take doses.
The product is not hugely effective, and needs to be taken in large doses just for a small effect. MET-Rx CLA Tonalin 1000 can be stacked with other weight loss aids and does not contain any stimulant ingredients. This particular CLA product is also poor value for money. In general, CLA supplements such as MET-Rx CLA Tonalin 1000 are not going to provide significant results, especially for someone who is looking to lose a large amount of weight.
Overall, CLA could play a small role in a larger weight loss system, we do not recommend MET-Rx CLA Tonalin 1000 to our readers.
