Nutribud is made from the leaf of a tree that comes from the semi-tropical jungles of South America. We import the raw material and make the extract at our facility. We take the dried leaf and run it through our proprietary extraction process. This is an all-natural process that maintains the naturally occurring vitamins, minerals and antioxidants needed for optimum growth. Naturally-occurring is the key phrase here. The following nutrients are naturally present in the extract: phosphorus, potassium, calcium, magnesium, sulfur, zinc, iron, manganese, copper. Nothing is added. Only what nature intended!
