What is TNvitamins Ultra Thin CLA?

TNvitamins Ultra Thin CLA is a dietary supplement that aims to support efficient fat metabolism and promote lean muscle development. When used alongside exercise, this product claims to help support your diet goals by providing you with an adequate amount of CLA that is difficult to obtain from an ordinary diet. TNvitamins Ultra Thin CLA aims to assist consumers in achieving a healthy body composition.


TNvitamins Ultra Thin CLA is on the upper end of the scale when it comes to active CLA (conjugated linoleic acid), boasting 80%. Whilst there are products out there that contain up to 85%, this is still fairly high. The CLA is derived from safflower oil, and other ingredients found in this product include gelatin, vegetable glycerin, and purified water and it comes in an easy-to-swallow softgel capsule.


TNvitamins Ultra Thin CLA should be taken daily. It is suggested to take one or more softgel each day or as directed by a health professional. We feel these directions could lead to harm, as there is no upper amount set, it is purely up to the consumer to decide a safe and effective dosage. TNvitamins clearly states that pregnant or lactating women, along with those who have underlying medical conditions, should consult with their doctors before use.


At just $7.58 (excluding shipping) for a bottle of 90 softgels, TNvitamins Ultra Thin CLA is one of the cheaper products on the market. Consumers can buy the larger quantity bottles of 180 softgels for $13.98 (excluding shipping), decreasing the price of each softgel. These quantities will last 3-6 months making them excellent value at less than 1c a day!

Possible Side Effects

TNvitamins do not mention any adverse effects on their product. However, it is clearly stated that if any are experienced then advice from a medical professional should be sought. Many customer reviews do not state any side effects, yet some have struggled to see a difference in belly fat when using the product.

Manufacturer’s Commitment

Whilst there is no form of money back guarantee on offer from TNvitamins, it does not mean that the company does not back their product. However, with many other similar products on the market that do offer a guarantee, TNvitamins Ultra Thin CLA could be seen as a risk on effectiveness.

The Bottom Line

Overall, we have found that TNvitamins Ultra Thin CLA offers a low-cost supplement to assist in increased muscle tone and metabolism. It appears safe for most consumers with not many reviews reporting side effects, however, it is no miracle pill. It needs to be taken alongside a healthy diet and plenty of exercise in order for weight loss and muscle toning to occur, leaving the consumer unsure if the changes in their body are a result of improved diet and exercise, or if they are from the product itself.
