How it compares in Diet & Nutrition
Across the 50 rated diet & nutrition products we track, the typical score is 4.4 out of 5. This one sits at 4.6, which puts it in the upper quarter of the category rather than level with it. Where almost everything is rated well, the gap at the top is small in points and large in practice.
It carries 3,630 ratings against a category median of 2,629. That is enough of a base to take the score seriously without treating it as settled.
On price it sits in the lower third of a category running from £2.50 to £96.90, where the midpoint is about £14.99. Cheaper than most while rating at or above the category norm is the combination worth looking for, and it is the main argument for this one.
