Swanson Health Products Tonalin CLA Review

Editor's Rating:

Swanson Health Products CLA Weight Loss Supplement is CLA capsules designed to promote lean muscle growth, fat reduction, and general fitness using a special blend of safflower oil derived CLA.


These supplements contain 1g of Tonalin CLA, a proprietary formula that contains a minimum of 78% CLA within a capsule made of gelatin, glycerin, caramel coloring, and water.

Tonalin CLA has been the subject of multiple scientific and clinical studies and has been shown to reduce fat percentage while increasing lean muscle mass. This supplement works by speeding the body’s metabolism to burn excess fat before it can be stored, and by encouraging current fat stores to be burned.

CLA has also been shown to help strengthen the immune system and regulate blood sugar levels.

It is derived from safflower oil, but also occurs naturally in small amounts in meat and dairy products. Because of changes to large scale agriculture, the amount of CLA available through diet has decreased, so it can no longer be consumed in sufficient quantities through diet alone.


For best results the manufacture suggests one softgel capsule two to three times per day with a glass of water before meals.

The company notes that individuals taking chitosan-based weight loss products should not take CLA. This supplement is not intended for children, and should not be used by those under the age of 18. Although thought to be safe, women who are pregnant or breastfeeding should consult a healthcare professional before taking CLA.

Possible Side Effects

In clinical trials of Tonalin CLA, there were no significant side effects observed. However, individual with allergies to any of the ingredients should obviously avoid this product.

Individuals who have metabolic syndrome or type 1 diabetes should consult a doctor before taking this supplement, as should anyone with bleeding disorders, as it can impact clotting. Because of this, anyone undergoing surgery should stop taking CLA at least two weeks before a scheduled procedure.


Swanson Tonalin CLA is currently on sale for $17.99 for a bottle of 180 tablets, down 32% from the regular price of $26.49. A bottle of 90 tablets is available through the company’s website for $9.99, down from $16.49. It can also be found through Amazon and other large pharmacy and supplement stores, but the manufacturer seems to have the best available price.


Swanson has a 100% money back guarantee on all of its products, so if you are unhappy with the product you can get a full refund, including shipping your unused portion back to the company.

Customer reviews for this product across multiple websites are positive, and indicate positive results for a wide variety of individuals, though with more enhanced results when used in conjunction with increased exercise. Users of CLA for multiple years note that they have switched to the Swanson brand because of its value and quality.


The primary benefit of this product is the type of CLA used, Tonalin, which is the same kind used in a number of scientific and clinical tests. This means that the ingredient is proven effective, especially since it is backed by a money-back guarantee and strong customer reviews. Because of the type of CLA used though, it is more expensive than some other comparable brands of CLA supplements. The gelatin capsules make this unsuitable for vegetarians, which is another negative overall, and the company does not note whether the CLA is derived from organic safflower oil.
