Expiration of Trace Elements

[Salty Sam]

Are there any expirations on trace elements, how long can they be on the shelf for and still be ok?

I don't generally recommend adding cocktails of trace elements, but if you choose to, you'll have to go by the manufacturer guidelines, if any, since we do not usually know what the actual ingredients are. In many cases, where there are no organic ingredients (vitamins, etc), the shelf life is probably quite long. Many years, perhaps.

Thanks....I found an almost new bottle of Inland Seas Strontium.
