Hi wallyworld –
If you’re referring to Swanson’s Soil-Based Organisms probiotic supplement, there is such a small amount of the trace nutrient (225 mg.) that I wouldn’t be concerned – there’s maybe 2 – 3 mg. of each of the trace nutrients. If you’re referring to Dr. STephen Langer’s Ultimate 15 Strain Probiotic with FOS – that contains even less (only 12.5 mg.) which would amount to almost nothing. If you want more detail on the trace nutrient component it’s sold as a separate supplement called “ConcenTrace” – it’s naturally derived from sea water and contains minerals such as lithium, boron, sulfate, etc. (all in very trace amounts).
