Zinc is essential for our well-being. Immune system, metabolism, cognition, eyesight, fertility ... hardly any bodily function can do without this trace element. This is because zinc is involved in a large number of enzymatic reactions, for example - either as a direct component of the respective enzyme or as a "catalyst". Through its role in protein synthesis, cell protection and cell division, it also contributes to the maintenance of Skin, hair and nails and nails.

Because the human body cannot produce zinc itself and can only store it for a short time, it must be supplied in sufficient quantities in the daily diet or through a high-quality dietary supplement. In times of stressin the pregnancy and breastfeeding or during growth the demand increases. 

The European Food Safety Authority (EFSA) gives the zinc requirement for adults as 10 mg/day. Incidentally, the actual requirement also depends on how much phytate ends up on the plate at the same time. Unfortunately, this is mainly found in wholegrain cereals, pulses and nuts, which are very good sources of zinc in themselves. But don't worry: sourdough fermentation, soaking, sprouting and other preparation methods reduce the phytate content considerably. Meat, eggs and dairy products also contain easily utilizable zinc - one reason why vegetarians and vegans are at greater risk of zinc deficiency. than omnivores. For them and all other people who want to ensure a continuous supply of zinc, we have developed our bestseller Zinc Compact. 

As already mentioned, the list of easily usable non-animal sources of zinc is relatively limited. However, guava leaves contain large amounts of the trace element in excellent bioavailability. GSE naturally only processes guava leaves from controlled organic cultivation.
