What is the copper-zinc ratio in the zinc capsules?

As the guava leaf naturally contains some copper, it is regularly tested for this for quality assurance purposes. The copper content of guava leaf extract is <10 ppm (= parts per million). If you follow our recommended intake of 1 capsule/day, you will consume 250mg of guava leaf extract. This contains 2.5 µg copper or less. This corresponds to an approximate ratio of 4000:1 (zinc:copper).
