AI summary of 80 customer reviews · September 2026

Customers most often mention the taste, with several saying it goes down more easily than other beet powders they have tried, and quicker recovery after long rides and runs. Cyclists are the largest group of reviewers, and a number of longtime users, some in their 60s, say they take it daily. The one product complaint came from a reviewer who said it did not mix well for them.

    Noticed a difference with in the first week of using Beetroot Pro and Endurance360. More endurance while training and quicker recovery afterwards. Feeling more energy and strength to push harder through my workouts. Highly recommend!

    I’ve taken many different products over the years. BeetRoot Pro has finally given me a clean energy source that has aided in my quick recovery from intense and long activities. I’ve noticed a significant difference in how I feel during and post long rides on the bike. This is a product I can stand behind and will continue to use well into the future.

    It doesn't mix well at all. Can't even drink it

Mechanism of Action

How It Works

The 60-minute cascade that turns a scoop into measurable threshold power.

01

Nitrate Uptake

T-60 MIN

An 8,000 mg standardized beet extract absorbs through the gut and enters the bloodstream intact, unlike raw beet juice, which varies batch to batch.

02

Conversion to Nitrite

T-45 MIN

Oral bacteria reduce nitrate to nitrite. Swishing with each gulp maximizes sublingual absorption and speeds the conversion.

03

Nitric Oxide Release

T-30 MIN

Nitrite converts to nitric oxide (NO) in active tissue. NO is the master signal molecule for blood vessel dilation.

04

Vasodilation + O2 Delivery

T-0 · Race

Blood vessels widen, oxygen delivery to working muscles climbs, and the oxygen cost of every watt drops. Threshold power goes up.

The Beetroot Pro
Advantage

Generic beet powders chase volume. We engineer for vasodilation.

8,000 mg beet extract per serving, standardized to 2% dietary nitrate: about 160 mg.

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.

/// Beetroot Pro® Insights
Is Beetroot Pro® safe for daily use?+
Yes. Beetroot Pro® is safe for daily use when taken as directed. Because it uses an extract rather than whole-root powder, it avoids excess fibers that can cause digestive discomfort with frequent use.
How long does Beetroot Pro® take to work?+
Beetroot Pro® typically begins to take effect in about one hour. This allows the nitrate-rich, water-soluble beetroot extract to convert efficiently into nitric oxide, supporting increased blood flow and oxygen delivery.
When should I take Beetroot Pro® for training?+
Take Beetroot Pro® approximately 60 minutes before your workout or event. Once active, it typically remains effective for 4 to 5 hours.
Does Beetroot Pro® contain caffeine?+
No. Beetroot Pro® contains no caffeine or stimulants.
/// Endurance360® Insights
Does Endurance360® help with muscle cramps?+
Endurance360® is formulated for muscle cramp support: it supports neuromuscular function and muscular endurance during long efforts. It is not an electrolyte product; cramping has several causes, so pair it with your usual hydration and sodium plan.
How long does the loading plan take?+
For best results, begin a 14-day loading period before key races to allow creatine and beta-alanine to fully saturate muscle tissue. You will notice peak benefits at 14+ days.
Can Endurance360® be used during both training and racing?+
Yes. Endurance360® is designed for daily use across both training and racing. It is stimulant-free and focused on muscular endurance and fatigue resistance.
Are Beetroot Pro® and Endurance360® third-party tested?+
Both products are manufactured in a cGMP certified facility in the United States. The active ingredients are not on the WADA or NCAA prohibited substance lists, but the products themselves have not been independently certified by anti-doping organizations. Drug-tested athletes should always confirm with their governing body before use.

About Beetroot Pro®

What Is Beetroot Pro®?

Beetroot Pro® is a sports nutrition brand for endurance athletes built around two supplements with published Supplement Facts panels (Beetroot Pro® for acute nitric oxide, Endurance360® for chronic capacity), a free Performance Lab tool suite of 19 calculators, and a 30-day money-back guarantee. Rated 4.9 out of 5 across 162 customer reviews. Customers include 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 combine 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 routines. 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 19 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 NSF GMP Certified (A rating) and UL GMP Certified facilities in the United States, and the manufacturing facility is also registered under NSF's GMP for Sport program. Every product is quality tested by an ISO/IEC 17025-accredited testing laboratory before release. These are facility-level certifications: Beetroot Pro® and Endurance360® have not individually completed NSF's separate, product-level Certified for Sport® testing.

Are Beetroot Pro® products vegan, gluten-free, and allergen-free?

Beetroot Pro® is vegan, gluten-free, and free of soy, dairy, nuts, and eggs, and it is sweetened with xylitol. Endurance360® is not vegan: its capsules are gelatin, which is listed first among its other ingredients. The full ingredient list 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.
