Natural Factors CLA Tonalin Review

Jenny Michelle

Natural Factors CLA Tonalin is a dietary supplement which, the company says, helps block the formation of fat and may help the formation of lean muscle mass. The conjugated lineolic acid in this product is produced by Cognis group under the registered trademark name Tonalin. Read our review below to learn more about this product.


  • Tonalin CLA (2000 mg)
  • Conjugated Lineolic Acid (1620 mg)

Tonalin CLA is derived through a proprietary process from safflower oil which is, itself, a synthetic oil. Safflower oil is said to be the richest source of CLA especially now that cattle (which in the past were commonly grass fed, which resulted in the production of CLA in their milk and meat) are most often grain fed which does not result in CLA production.


The manufacturer recommends taking one to two capsules before meals, three times per day or as directed by your health practitioner. Before you start taking the CLA supplement, it is recommended that your consult your health-care provider first.


The manaufacturer, Natural Factors, seems to be going for the high-end market. At the time of writing, you could buy a 90-capsule bottle on Amazon for $29.33, which is quite high. However, you could choose to purchase the “bonus pack” that was on offer on Amazon as well with two 60-capsule bottles for $23.98 (which is better but still not a bargain).


Bear in mind that Natural Factors CLA Tonalin does not come with a money back guarantee nor is any type of return policy specified on the product website.

Natural Factors CLA Tonalin – Conclusion

Perhaps the best thing we can say about Natural Factors CLA Tonalin is that the dosage looks about right, in line with competitors’ offerings. And while the product has garnered some positive ratings from Amazon customers (and a couple of negative ones) there were too few customer reviews (11 in total at the time of writing) to rely on them for a true indication of the product’s effectiveness. Given the high-end pricing and the lack of a return/refund policy it is difficult for us to recommend this product.
