Aren't the side effects mimicked so that participants won't see the lack of them and then know that they're taking the placebo which will defeat the double blind study?

For example, if you're testing fish oil, you wouldn't use a sugar pill since it's easy to know what you're taking by looking at it. You would use something like olive oil.

There are certainly ways to simulate fish oil with biologically inert ingredients.

Earlier quoted context omitted.

So, is there anything that could be said to be biologically inert in any and every scenario?

Chalk?

Cellulose as well? Dicalcium phosphate is also a common tablet filler, though I don't know if it's biologically inactive.
