What is Natural Factors CLA Tonalin?

Natural Factors CLA Tonalin is a dietary supplement indicated for fat reduction and muscle toning. It is formulated from Conjugated Linoleic Acid (CLA), a fatty acid that occurs naturally. Among other properties, CLA blocks fat from filling fat cells by modifying the enzyme lipoprotein lipase, which helps the body accumulate fat. This enzyme is also believed to offer other fat burning properties through its interactions with the body’s metabolic processes.

This supplement’s long-term use may help fight obesity, high blood pressure, diabetes and other ailments caused by excess fat.


Natural Factors CLA Tonalin comprises a 2000mg Tonalin CLA blend comprising of 1620mg Conjugated Linoleic Acid. The ingredients that make up the softgel capsule include glycerin, gelatin, caramel, and purified water.

In addition to managing fat, CLA may provide a host of other health benefits. Studies indicate that the inclusion of CLA in your daily diet may prevent tumor cell growth by 50%, thus helping to stem off cancer of the breast, stomach, lungs, and skin.

CLA has also shown promising action against diabetes. In addition to lowering circulating glucose levels, it enhances insulin action on the body’s cells. However, you need regular consumption of CLA for a minimum of eight weeks for these effects to start manifesting.


Natural Factors CLA Tonalin comes in 1000mg softgel capsules. The manufacturer suggests a daily intake of 1 to 2 softgel capsules, three times a day, or as directed by a health practitioner. It is also advised to take this supplement before meals.

Possible Side Effects

CLA can be converted naturally by the body from food sources, mainly from dairy and meat. Thus, when taken in moderate amounts, it is largely safe. However, the CLA found in supplements is extracted artificially. The supplement form is easier to overdose on and more likely to cause side effects such as diarrhea, nausea, stomach upset, and fatigue if you consume high doses.

CLA taken in medicinal amounts is safe for children and pregnant women but effects of long-term consumption have not been thoroughly studied. Therefore it is better to keep on the safe side and avoid use.

Manufacturer’s Commitment

There is no guarantee provided with the purchase of this supplement. You carry all the potential risks when you buy it. It is important to pay attention to the return policy of the store where you purchase the product from.

The Bottom Line

We are aware of CLA’s benefits in reducing fat and preventing disease, which this supplement attempts to ride on in order to woo potential buyers. However, the manufacturer makes little attempt at offering sufficient product and pre-purchase information. What’s more, the manufacturer is not willing to stand by their offering through a solid guarantee.

Therefore, we came to the conclusion that there are better options available on the market.
