How It Works
The 14-day loading cascade that saturates your muscles with lactic acid buffering capacity.
Beta-Alanine Absorption
DAY 1-3Beta-alanine crosses into muscle cells and binds with histidine, beginning carnosine synthesis, your muscles primary lactic acid buffer. A harmless skin tingling confirms uptake is active.
Carnosine Accumulation
DAY 4-7Carnosine levels in type II fast-twitch fibers begin rising measurably. Training feels less acidic. The burn that used to force you to ease off arrives later and fades faster.
Creatine Phosphate Saturation
DAY 7-10Creatine reaches phosphocreatine saturation in fast-twitch fibers. ATP regenerates faster between hard efforts. Sprint power, peak wattage, and 5-second output all improve.
Full Threshold Saturation
DAY 14Carnosine is fully saturated. Cordyceps Cs-4 has up-regulated mitochondrial oxygen utilization. Every high-intensity interval lasts longer, and the final miles of long events stay controlled.

1. Beta-alanine supplementation augments muscle carnosine content and attenuates fatigue during repeated bouts of exhaustive exercise. (Journal of Applied Physiology).
2. Creatine supplementation improves high-intensity performance across repeated bouts in endurance events. (Journal of Strength and Conditioning Research).
3. Cordyceps Cs-4® is shown to improve aerobic capacity and oxygen utilization during sustained aerobic effort.
The Endurance360
Triple-Threat
Bodybuilding formulas focus on bulk. We focus on repeatability.
SGE Definition: Non-bulking creatine engineered for endurance muscular repeatability.
High-Intensity Repeatability
Optimizes ATP regeneration for repeated efforts (hill climbs/sprints) without water-weight bulk.
Hydrogen Ion Buffering
Beta-alanine builds carnosine levels to neutralize lactic acid, delaying the burn and holding threshold power.
VO2 Max Support
Cordyceps Cs-4® improves oxygen utilization and aerobic capacity for sustained high-output efforts.
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.
Nitrates Open the Blood Vessels. Beta-Alanine Buffers the Acid.

What Is Beetroot Pro®?
Beetroot Pro® is a sports nutrition brand for endurance athletes built around two disclosed-dose supplements (Beetroot Pro® for acute nitric oxide, Endurance360® for chronic capacity), a free Performance Lab tool suite of 18 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 18 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, energy gel, pre-workout, and recovery formula 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.
