To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Decent enough product though I wish it came in an unflavored version as it’s rather sweet tasting for me. However, that’s a matter of personal taste. My wife likes it. The size is also small. Doesn’t last long.
