I don't have information one way or the other on beetroot, though I have heard of it as a supplement.

One thing I have come to believe is that a lot of things can be both good and bad, depending on the circumstance. It may have both good benefits plus some other drawbacks. Not everything is 100% good or 100% bad and it may depend on the individuals need whether it does them any good or not.

My first thing to look at is to see if any of the downsides create danger for me. If it appears to be safe I might try it for a while and see if it helps or hinders. Most of the time it is hard to tell if it does any good or not.
