How to choose a good beetroot supplement
Judge a beetroot supplement on form, a plain milligram amount versus a concentration ratio, whether nitrate is measured and stated, added ingredients, and price per serving.
A beetroot supplement is worth judging on five plain things: the form (powder, extract, or juice), the actual amount per serving in milligrams rather than a concentration ratio, whether a nitrate figure is stated and measured, what else is in the capsule, and price per serving. Measured against its own checklist, Electric Tiger Beetroot is a plain 1300 mg whole-powder capsule with no added fillers, and it doesn't state a nitrate amount — which several competitors don't either.
1. Form: powder, extract, or juice
Beetroot supplements come as dried whole-root powder (milled and encapsulated), a concentrated extract (often described as a ratio like "20:1"), or dried or liquid juice concentrate. These aren't interchangeable — most of the research measuring an actual effect uses juice, dosed to a specific nitrate amount, while whole-powder capsules are the least concentrated form for nitrate specifically, even though they deliver the whole root's fiber and other nutrients. Electric Tiger Beetroot is whole dried root powder, milled — not an extract or juice concentrate.
2. A plain milligram amount, not a concentration ratio
Some labels state "8,000 mg equivalent" or "20:1 concentrate" rather than a plain milligram figure. That phrasing describes how much raw root was concentrated down during manufacturing, not how much ends up in the capsule you swallow — a lab analysis of 50 commercial beetroot supplements found this kind of ratio marketing common, and separately found actual nitrate content varied widely between products regardless of how they were marketed. A plain milligram number, like our 1300 mg per serving, is easier to compare directly, even though it doesn't tell you the nitrate content on its own either.
3. Whether a nitrate dose is stated and measured
The research that finds an effect on performance doses to a specific nitrate amount — a 2025 review found 515-1,017 mg of nitrate a day associated with a measurable, if small, effect. Almost no commercial beetroot capsule states a lab-measured nitrate figure on the label; the 2023 lab analysis above found the highest-dose product it tested still supplied only 169 mg of nitrate per daily dose, and most products supplied far less. Electric Tiger Beetroot doesn't state a nitrate amount either — this is a real gap in the whole capsule category, not a competitive edge for anyone, and worth knowing regardless of which brand you choose.
4. What else is in the capsule
Check the "other ingredients" line, not just the front label. Electric Tiger Beetroot's only other ingredients are the vegetable capsule shell (hypromellose), microcrystalline cellulose (a filler/flow agent used in small amounts to fill the capsule), and magnesium stearate (a common flow agent) — no added sugar, no proprietary blend, and no second active ingredient diluting the beetroot itself.
5. Price per serving
Price per serving is the number that actually compares two different bottle sizes and subscription structures fairly — sticker price on the front doesn't. Electric Tiger Beetroot is as low as $14.38 a bottle on subscription, 30 servings a bottle, which works out to about $0.48 a serving.

Questions people ask
Which beetroot supplement should I buy?
Judge it against the five criteria above — form, a plain milligram amount, whether nitrate is measured and stated, what else is in the capsule, and price per serving — rather than a marketing number like "8,000 mg equivalent." No commercial capsule we've found, ours included, states a lab-measured nitrate figure, so that's a gap across the category rather than a reason to prefer one brand over another on its own.
Where can I buy beetroot supplements?
Electric Tiger Beetroot is sold directly on our site, as low as $14.38 a bottle on subscription.
Is a beetroot extract better than beetroot powder?
They're different products for different purposes. An extract concentrates specific compounds, which can mean a smaller capsule for the same amount of a target compound, if the concentration is accurately measured and stated; a whole-powder capsule like ours delivers the dried root as-is, without concentrating any single compound. Neither has been shown to reliably reach the nitrate doses used in performance research — see beetroot benefits: what the research does and doesn't show.
Does "organic" or "non-GMO" matter when choosing a beetroot supplement?
Organic beetroot means the root was grown to USDA organic standards; our label states organic. Non-GMO is a separate claim, and we don't state it on our label — check a specific product's label directly if that matters to you.
