What Beetroot Brings
Beetroot (or beet root) is one of the richest dietary sources of nitrates — not to be confused with the nitrate medications discussed elsewhere, but naturally occurring compounds in vegetables. The body converts these dietary nitrates into nitric oxide through a pathway involving oral bacteria and the digestive system. This gives beetroot a different route to boosting nitric oxide than the amino acids L-citrulline and L-arginine, which is exactly why combining it with them in Nitric Boost Ultra makes sense — it supports nitric oxide production from another angle.
The Exercise and Performance Evidence
Beetroot has become one of the most studied natural performance aids, particularly in the form of beetroot juice. Research has shown that beetroot nitrates can improve exercise efficiency, endurance, and time-to-exhaustion in some studies — athletes use it to potentially get more out of each breath of oxygen. The effects are among the better-supported in sports nutrition for a natural ingredient. This makes beetroot a genuinely evidence-backed inclusion in a circulation-and-performance formula, complementing the amino acids with real research behind it.
Blood Flow and Blood Pressure
Beyond exercise, beetroot’s nitric oxide boost supports general blood flow and has been shown to modestly lower blood pressure in various studies — a benefit for cardiovascular health in the right context, but also part of the reason the whole formula carries blood-pressure cautions. The blood-pressure-lowering effect of dietary nitrates is genuine and reasonably well documented, which is a point in beetroot’s favour for healthy people but a reason for caution for anyone on blood-pressure medication, ED drugs or nitrate drugs.
The Harmless Red-Urine Effect
A quirk worth explaining: beetroot can turn urine and stools a harmless pink or red colour, a phenomenon called beeturia. This surprises and sometimes alarms people, who may fear blood, but it is completely benign — simply the beetroot pigment passing through. It is more noticeable in some people than others. Knowing about this in advance saves unnecessary worry. It is not a side effect in any harmful sense and not an allergic reaction — just a colourful, harmless consequence of beetroot’s natural pigments.
Cautions to Know
Beetroot is very safe and well tolerated as a food and supplement ingredient. Its main considerations are the harmless red urine, its contribution to the formula’s blood-pressure-lowering effect (and thus the interaction cautions), and — for people prone to kidney stones — that beetroot is relatively high in oxalates, which is worth noting for that specific group. For most people, though, beetroot is one of the gentlest and best-evidenced ingredients in a nitric oxide formula, with a strong safety profile.
The Bottom Line on Beetroot
Beetroot is a well-researched, gentle ingredient in Nitric Boost Ultra, delivering dietary nitrates that boost nitric oxide by a different route than the amino acids, with genuine evidence for blood flow, blood pressure and exercise performance. It harmlessly turns urine red (beeturia) — no cause for alarm. Its blood-pressure-lowering effect contributes to the formula’s interaction cautions, and kidney-stone-formers should note its oxalate content. Overall, beetroot is one of the formula’s stronger, safer ingredients.
The Way We Evaluate Nitric Oxide Supplements
We judge a product like Nitric Boost Ultra the way a careful buyer would: use it for a full quarter, watch circulation, pumps and performance, and weigh the L-citrulline and beetroot doses against the research rather than trusting the label. Detailed user experiences inform our view more than star averages, and we foreground the interaction that makes this category different — nitric-oxide boosters lower blood pressure, which is dangerous with nitrates or ED medication. Supplements support blood flow; they do not treat medical conditions, which need a doctor.

Frequently Asked Questions
What does beetroot do for blood flow?
Beetroot is rich in dietary nitrates the body converts to nitric oxide, improving blood flow and modestly lowering blood pressure, with genuine evidence for exercise performance too.
Is the red urine from beetroot dangerous?
No. Beetroot can harmlessly turn urine or stools pink-red (beeturia) — it is just the pigment passing through, not blood or a reaction.
Does beetroot really improve exercise performance?
Yes, it is one of the better-researched natural performance aids. Studies show beetroot nitrates can improve exercise efficiency, endurance and time-to-exhaustion in some cases.
Are beetroot nitrates the same as nitrate medications?
No. Beetroot contains naturally occurring dietary nitrates, different from nitrate drugs like nitroglycerin. But because both affect nitric oxide, the formula still carries blood-pressure cautions.
Is beetroot safe for everyone?
It is very safe for most people. Those prone to kidney stones should note its oxalate content, and anyone on blood-pressure, ED, or nitrate medication should consult a doctor.
Can I just drink beetroot juice instead?
Beetroot juice is a well-studied way to get dietary nitrates. A supplement offers convenience and a combined formula, but juice is a legitimate natural alternative for nitric oxide support.
