Is a trial that synthesises one component good for the patient?

I have just watched

nutritionfacts.org/video/be...

which has the interesting take-away many if not most trials are funded to make money by extracting and/or synthesising an interesting chemical from one plant or another. They do this because they can create a pill out of the results and also because trial are easier to organise.

But is that going to lead the best solution for the patient? Is the whole better than the sum of the parts?
