Listol is a natural supplement advertised as an alternative product for ADD and ADHD. The company behind it is Progressive Health, a private American company that started back in 1997.
From the start we need to point out that the official product website offers excellent information regarding the formula and its exact purpose. Listol is claimed to increase attention span, decrease impulsiveness, and increase the ability to process information quickly.
The ingredients include GABA, Huperzine A, Vitamin B6, Magnesium, Iron, Calcium,Zinc, DMAE, and Phosphatidylserine.
The impressive number of positive testimonials is quite refreshing. However, consumers see the first improvements between 6 to 8 weeks, which basically means you need to order at least two bottles of Listol to continue the treatment for so long. Considering this, we have to point out that Listol is quite expensive compared to other similar products.
