Mr Neal Promax Lean Protein Bar- Low Sugar ?
The product description states low sugar. However the nutrition table on the actual packet is different to the one on the website. The bar is very sweet, not the low sugar I was expecting.
The MaxiNutrition Team:

Good morning, 

Thank you for you taking the time to leave a review. 

We are sorry to hear that the Promax Lean bar is not to your liking.

Please be aware that this product is low in sugar and that the Polyol listed in the nutritional information is a sugar free sweetener (also known as a sugar alcohol), so this doesn't affect the sugar content of the bar. This was listed in the ingredients and we will update the nutritional information shortly.

If you have any questions please contact the team directly -


Kind regards,
