AST Sport Science CLA 1000 - Does It Work?-Review

What is AST Sports Science CLA 1000?

This is a review of CLA 1000 manufactured by AST Sports Science. Containing the active ingredient conjugated linoleic acid, a fatty acid that promoted as a weight loss aid, CLA 1000 claims to enhance and promote lean muscle and the loss of fat. In its natural form, CLA is found in many types of meats and dairy products. However, this supplement’s main ingredient has been extracted from Safflower.

Ingredients & How It Works

  • Conjugated Linoleic Acid
  • Gelatin
  • Glycerin
  • Purified Water
  • Carob

CLA 1000 contains active ingredients associated with the reduction of body fat and the promotion of muscle development. However, the inclusion of gelatin means that this product is not suited for consumption by vegetarians and vegans. It is also not specified whether the glycerin in this product is derived from a plant or animal source. Additionally, when consumed in improper amounts glycerin may have a laxative effect.

Daily Serving

The manufacturer suggests that one to two soft gel capsules should be taken, between two and three times daily with meals. This instruction is, however, somewhat vague as consumption could vary between two or six softgels. This does not suggest what dosage would be more beneficial for the weight loss process. Furthermore, studies have shown that 3.4 g of CLA should be used for optimum effect - which is far from this product’s lowest ( 2g) and highest (6g) recommended dosage.

The Cost

At present time you can buy AST Sports Science CLA 1000 from the manufacturer’s website for $23.99 per bottle. Each bottle contains 90 softgels. According to this product’s label suggests that each bottle has enough softgels for 30 servings - which does not match the suggested dosage. Resulting in the need to purchase multiple bottles at a time. The manufacturer is also not offering any discounts or special offers on the bulk purchase of this supplement - making this a pricey option.


After much research, we could not find any satisfaction guarantee. Thus questioning the effectiveness of this product, particularly as the website seems to be very confident in this supplement. The only type of guarantee we found was related to damaged goods. If you buy CLA 1000 directly from the manufacturer and the product is returned, they will refund the amount for the purchase excluding shipping. They are also not liable if your shipment is destroyed or seized by customs.

Our Review Summary Of  CLA 1000

Concluding our review of AST Sports Science CLA 1000, we liked that this product contains a key ingredient derived from a plant-source, which can assist in fat loss programs. We also liked that the manufacturer offers a return policy. However, we were concerned that there was no guarantee connected to this weight loss supplement and that the gelatin used renders this product not suitable for vegetarians or vegans. Another concern we found was the vague indication for use, which will require the customer to purchase several bottles at no discount.
