Hi all,

I have a student that I have tasked with measuring the nitrate (and nitrite) content of a number of beetroot juice products (ideally a dozen or more). We're specifically looking for ones that are 1) marketed to athletes/as enhancing athletic performance, and 2) do not contain other ingredients (e.g., arginine) aimed at increasing nitric oxide production. Here is what we have acquired so far:

Beet It! (regular juice)
Beet It! Sport ("platinum" concentrate)
Red Rush
Red Ace
Beet-Power
Beet Elite
Beet Performer
Knudson organic beet juice
Biotta organic beet juice

I would appreciate any additional suggestions, especially if you can tell me how to lay my hands on the product.

Thanks!

P.S. If anybody wants to buy the leftovers, I have a fair bit of stuff to unload.
