Total Beets earns its high ranking for one substantive reason: it's among the very few mainstream beet powders that openly adds standardized NO3-T nitrates on top of whole beet root. That means it's targeting the nitric-oxide pathway with the actual precursor — inorganic nitrate — rather than hoping the beet mass alone carries enough. Since nitrate is the active the human trials dose by (Wylie 2013), explicitly building it into the formula is exactly the right instinct, and it's what separates Total Beets from a plain powder.
The honest limits are two. First, despite adding nitrates, it still doesn't print a total nitrate figure — so it's more transparent than an undisclosed-nitrate beet powder but less so than a concentrated extract that states a nitrate percentage. Second, the beet mass itself is modest at 3 g, and it's a flavored, sweetened drink mix rather than a clean single ingredient. At about $0.90 a serving it's well-priced, and the added-nitrate design makes it the sharpest mainstream beet drink for someone who wants the NO precursor explicitly in the mix. Here's the full breakdown.
