Dietary nitrate (beetroot juice)

Dietary nitrates, Beet juice, BRJ, Beetroot shot

Forms: Beetroot juice and concentrated beetroot shots, nitrate-rich vegetables (beetroot, spinach, rocket, celery) and nitrate salts; in a large meta-analysis the salts did not clearly help, while juice did.

SupplementsOver the counter (varies by country)Evidence: limited human data

Inorganic nitrate from vegetables such as beetroot, which mouth bacteria and the body turn into nitric oxide. One of the few supplements the IOC rates as having good evidence of a performance benefit.

What it gives

What people use it for and what the sources report. Strength is a general category from the literature: mild, clear or strong.

Purpose

Used by endurance and team-sport athletes to make muscle work more efficient, extend time to exhaustion and help in high-intensity, intermittent efforts. It also lowers blood pressure slightly.

What people seek and what studies show

Meta-analyses of 80 and 123 trials find a small but consistent benefit, clearest in efforts of 2–10 minutes; well-trained endurance athletes gained little or nothing. Over weeks it did not add to training adaptations. Antibacterial mouthwash blunts the effect. Systolic blood pressure fell by about 4 mmHg in short trials.

Possible side effects

Possible does not mean certain: whether they appear depends on dose, duration, individual response and monitoring. Below — what to watch for and how to notice it early.

2 possible side effects

level · how often it is reported
Low
Nausea, GI upset, pancreatitis risk
Stomach upset in some athletes; pink or red urine and stools after beetroot (beeturia, in about 10–14% of people) are harmless.
How to notice: Nausea, fullness, constipation or diarrhea.
possible
Low
Black-market quality risk (fakes, contamination)
Low risk as a single ingredient, but concentrated shots and pre-workout blends vary in quality; choose third-party-tested products (Informed Sport, NSF).
How to notice: Unexpected effects, pain or infection, a stronger or weaker effect than expected.

How to lower the risks

For 1 of 2 possible side effects there are specific ways to lower the chance: everyday measures, supplements and options a doctor may consider. For the rest — general advice. No measure removes a risk completely.

Low-level side effects

Digestion
Smaller meals, enough fluid and fiber; a doctor for severe abdominal pain.
Measure
Working with a doctor
Supplement or OTC product
How each option helps (2)
  • Working with a doctor — Assesses persistent vomiting or severe belly pain (possible pancreatitis or gallstones) and adjusts prescribed GLP-1 treatment when nausea persists.
  • Pancreatin + dimeticone (Pankreoflat) — May ease heaviness and gas after meals; can cause nausea or diarrhea. Not for pork or cow's milk protein allergy (anaphylaxis reported) or early acute pancreatitis.
Product quality
Products obtained without a prescription are often fake, mislabeled or non-sterile, and there is no way to check at home. For legal supplements, look for third-party testing (Informed Sport, NSF).

Check-ups and blood tests

Which tests and check-ups to do and when. This is a guide — agree the exact schedule with your doctor.

The sources list no specific tests for this substance on its own. Together with other substances, the stack check shows the tests for the whole combination.

For women

Fewer studies include women: one meta-analysis saw no clear benefit in women-only studies, another a small gain in power but not in strength or sprints.

Myth & fact

Myth

“Are nitrate salts the same as beetroot juice?”

Fact

No. In a 123-trial meta-analysis the salts did not clearly help while juice did. Concentrated sodium nitrite and nitrate salts are poisons in large amounts: they cause methemoglobinemia, and deaths are reported.

Combinations

No specific combination notes for this substance yet. The stack check still adds up side effects that several substances share.
