Trace Minerals and Vegetable Shortening

Dear Dr. Jeff,

I purchased a bottle of the ConcenTrace Trace Mineral Drops that you sell on your website a few weeks ago. Recently, I received a vitamin/mineral supplement from another company and I just noticed this supplement also contains trace minerals. Is it possible to "overdo it" on the trace minerals?

Also, I heard of a trick to help keep hands soft and slow down the aging process. Basically you use vegetable shortening and sleep with a pair of gloves on. This may sound silly but, can the shortening get in your blood stream and cause problems, or do you think this would be safe to do?

Thank you!
