The Cognitive Review assesses focus and cognition products by what their labels actually say — which form of each active, whether every amount is printed, and whether a standardisation percentage is stated. Everything we score can be checked by anyone holding the pack.
Rankings
We buy the products, read every panel, and score them on factors stated before the first product appears.
