| I was wondering if the Copper in this thermal water has the potential to react with other products to cause any of the negative effects possible in copper peptides? Thanks |

| Hard to say. It depends on numerous factors, including copper concentration, its chemical state, pH, etc., etc. |

| That's quite low -- shouldn't create problems, especially at neutral pH. |
