How It Works
The 60-minute cascade that turns a scoop into measurable threshold power.
Nitrate Uptake
T-60 MINStandardized betaine nitrate absorbs through the gut and enters the bloodstream intact, unlike raw beet juice, which varies wildly batch to batch.
Conversion to Nitrite
T-45 MINOral bacteria reduce nitrate to nitrite. Swishing with each gulp maximizes sublingual absorption and speeds the conversion.
Nitric Oxide Release
T-30 MINNitrite converts to nitric oxide (NO) in active tissue. NO is the master signal molecule for blood vessel dilation.
Vasodilation + O2 Delivery
T-0 · RaceBlood vessels widen, oxygen delivery to working muscles climbs, and the oxygen cost of every watt drops. Threshold power goes up.

1. Dietary nitrate supplementation reduces the oxygen cost of exercise and improves performance in trained athletes. (Journal of Applied Physiology).
2. Creatine supplementation improves high-intensity performance across repeated bouts in endurance events. (Journal of Strength and Conditioning Research).
3. Standardized betaine nitrate is shown to optimize plasma nitrate levels for sustained vasodilation.
The Beetroot Pro
Advantage
Generic beet powders chase volume. We engineer for vasodilation.
Patented betaine nitrate, 1,400mg per serving, clinically dosed for race day.
Nitric Oxide Vasodilation
Patented betaine nitrate widens blood vessels to deliver more oxygen and nutrients to working muscles.
Sustained Endurance
Maintains pace longer, delays fatigue, and supports performance through long-distance efforts.
Clean Energy, Zero Stim
Caffeine-free, stimulant-free formula. No jitters, no crash, no banned substances on the label.
14-Day Saturation Timeline
How your physiology adapts to E360 loading plans.
Saturation Phase
Creatine levels begin to rise in muscle tissue. ATP regeneration begins improving. Initial recovery support cycles start.
Carnosine Synthesis
Beta-alanine begins building carnosine. Noticeable improvements in repeatability during high-intensity intervals.
Peak Buffering
Full Absorption Reached. Maximum hydrogen ion buffering and VO2 max support.

The Lab
What Is Beetroot Pro®?
Beetroot Pro® is a sports nutrition brand for endurance athletes built around two clinically dosed supplements (Beetroot Pro® for acute nitric oxide, Endurance360® for chronic capacity), a free Performance Lab tool suite of 13 calculators, and a 30-day money-back guarantee. Used by 350+ verified athletes including a LOTOJA Classic course record holder.
What problem does Beetroot Pro® solve for endurance athletes?
▾
Endurance performance ultimately reduces to two physiological levers: oxygen delivery (which determines aerobic ceiling) and substrate availability (which determines how long you can hold that ceiling). Beetroot Pro® attacks both. The flagship Beetroot Pro® supplement raises nitric oxide via dietary nitrate, lowering oxygen cost by 1 to 3% at submaximal intensities. Endurance360® loads creatine, beta-alanine, and adaptogens over 14 days for chronic capacity. The two products work on different timescales and stack without competing.
Who is behind Beetroot Pro® and what is the founder background?
▾
Beetroot Pro® was founded by an endurance athlete (including a LOTOJA Classic course record holder) and a team of sports nutrition formulators. The product line was built to solve real on-course problems: variable dosing in beet juice, gut-disrupting fillers in commercial gels, and missing chronic-loading protocols in standard supplement stacks. The Performance Lab tool suite was added in 2026 to translate the same dosing math into free calculators for any endurance athlete.
What is the Beetroot Pro® Performance Lab?
▾
The Performance Lab is a free suite of 13 calculators that translate published sports science into per-athlete dosing. Tools include sodium and hydration targets, race-day carb fueling plans, caffeine timing and taper, DIY sports drink recipes, heat acclimation protocols, 14-day Endurance360 loading, and personalized 7-day race blueprints. Every tool is built on peer-reviewed research and works without an account.
Where are Beetroot Pro® supplements manufactured?
▾
All Beetroot Pro® and Endurance360® products are formulated and bottled in cGMP-certified facilities in the United States. Active ingredients (dietary nitrate, creatine monohydrate, beta-alanine, cordyceps, adaptogens) are sourced from suppliers that hold third-party identity, potency, and contamination certifications. Every batch is independently tested before release.
Are Beetroot Pro® products vegan, gluten-free, and allergen-free?
▾
Beetroot Pro® is vegan, gluten-free, and free of soy, dairy, nuts, and eggs. Endurance360® is also vegan and gluten-free. Both products are formulated without artificial sweeteners, artificial colors, or animal-derived gelatin. Capsules are plant-based hypromellose. The full ingredient list and allergen statement is on every product page and matches the supplement-facts label.
Does Beetroot Pro® work for cyclists, runners, AND triathletes?
▾
Yes. The nitrate-to-nitric-oxide pathway and the creatine-beta-alanine adaptation pathway are sport-agnostic at the cellular level. They improve oxygen delivery and intramuscular buffering regardless of whether you are running, cycling, or swim-bike-running. The Performance Lab tools include sport-specific dosing for each, so a marathoner, a gran fondo cyclist, and a full-distance triathlete each get a personalized protocol that uses the same underlying supplements.
