Refreshall is a high potency product that, at two tablets daily, provides the full 6000mg of ginkgo that has been in scientific studies, plus three other herbs, lemon balm, sage and rosemary all at relevant levels. We use the same premium quality ginkgo in Refreshall as we do in our straight ginkgo product and VeinTain. It is the highest quality ginkgo extract available as we insist on a raw material that has low levels of a naturally occurring, but unwanted compound, called ginkolic acid. No other company in the UK insists on this grade, but in Germany only this grade is permitted. Ginkgo is the herb most associated with memory thanks to its gentle ability to improve the flow of blood, and therefore oxygen and nutrients, to the brain. Daily intake: 2 tablets
