Yeah, um... don't waste your money. Diatomaceous earth is efficacious as a pest control product, but beyond that... you're just eating sand. Expensive, fancy sand.

It probably won't hurt you in supplement-sized quantities, but silica is almost completely biologically inert. There's a reason that a lot of implanted medical devices are encased in glass -- glass is made of silica, and silica does absolutely nothing in the body.

Now, if you were a bird, there might be a decent argument that it would help with your digestion, but most avian doctors recommend calcium (such as cuttlebone) over silica because the calcium is more biologically useful and is less likely to get impacted in your crop. But then again, you aren't a bird.
