Windmill Health Products Raspberry Slim Review

Manufacturer’s Claim

This review takes a look at the product Raspberry Slim by Windmill Health Products which aims to help you lose weight while following a healthy eating plan and exercise. Raspberry ketones are a compound found in raspberries that give raspberries their strong smell and which researchers have found to help burn fat. The manufacturer also states that because it is high in fiber, it keeps you feeling fuller for longer. The manufacturer states that this product is manufactured in a facility that is GMP certified.


Raspberry Slim contains a blend of ingredients and isn’t only purely raspberry ketones. It contains:

  • Green Tea Leaf Extract – 262.5mg
  • Raspberry Ketones – 125mg
  • Concentrated Berry Extracts (Acai Fruit, Blueberry Fruit, Raspberry Fruit, Mulberry Leaf) – 50mg

The manufacturer does not go into detail about the ingredients in this product. It mentions the key ingredient is raspberry ketones, however, the amount of raspberry ketones is lower than the green tea leaf extract. It is also lower than that found in other raspberry ketone supplements. Raspberry ketones help speed up metabolism which helps the body burn fat. It also helps to stop new fat from being stored. Research shows that for raspberry ketones to be effective, they need to be derived from real raspberries. Green tea extract contains caffeine and is also an effective fat burner.


The manufacturer recommends taking one capsule two times a day with a meal. This will only provide you with a daily serving of 250mgs of raspberry ketones. The optimal amount is 1000mg, so this is significantly lower.


Raspberry Slim is not sold directly from the manufacturer but they have provided a store locator function on their website to make finding the product easier. We found this product sold on Amazon for between $18 and $19. The price will vary depending on which retailer you buy from. One bottle will provide you with a one-month supply.

Possible Side Effects

There are no side effects associated with this product. This product is only designed for adults and should be kept out of the reach of children. It is important to note that this supplement contains 50mg of caffeine per capsule.


The manufacturer guarantees quality and that all quality specifications are met during the manufacturing process. The manufacturer does not, however, provide a money-back guarantee for unsatisfactory results. We find it disappointing when a manufacturer fails to back up their product with a satisfaction guarantee. You should pay attention to the return policy of the store where you are buying the product from.

Windmill Health Products Raspberry Slim Review – The Bottom Line

This product seems to contain useful ingredients for helping you to burn fat and reach your weight loss goals. However, their actual effectiveness may be in question. The dosage of raspberry ketones is very low compared to other products. It is also not stated by the manufacturer where they are derived from. It is also unfortunate that the manufacturer does not provide a satisfaction guarantee despite following quality manufacturing standards. There are other products available that meet industry standards, follow the best possible dose, and come backed with satisfaction guarantees.
