Make sure any liquid mineral supplements you buy do not contain any aritificial ingredients/
preservatives - in particular thimiserol which is a preservative used in vaccines/injections/liquid minerals etc. Thimiserol contains mercury, which is one of the most toxic chemicals known and has been implicated in cancer and immune-dysfunction amongst other things.
Personally I prefer to get my trace minerals from good ol' fashioned sea-salt. Its the way our ancestors got theirs for thousands of years. I look upon it as God's mineral supplement. And hey it's a lot cheaper.
See the link below for the full benefits of sea-salt.
