Certified Organic Beet

Q: Is certified organic beet more effective than conventional?

There is no direct evidence suggesting that certified organic beet is more effective than conventional beetroot supplements. The efficacy is primarily linked to the nitrate content, not the cultivation method.

Q: How quickly does beetroot supplementation work?

The beneficial effects of beetroot supplementation on blood pressure and exercise performance typically appear within 2-3 hours after ingestion, making it suitable for acute use before activities.

Q: Are there any risks of long-term use?

Long-term safety data for beetroot supplementation are limited, but studies lasting several weeks have not reported any significant adverse effects, suggesting a favorable safety profile for short to medium-term use.

Q: Can beetroot juice replace medications for hypertension?

No, beetroot juice cannot replace prescribed medications for hypertension. While it can help lower blood pressure, it should be considered a complementary approach and used under medical supervision, not as a substitute for prescribed therapy.

Also known as: Beetroot, Beet juice, Beetroot juice (BRJ), Beetroot-based supplements (BRS), Certified organic beet, Beta vulgaris

Overview

Certified organic beet, derived from the Beta vulgaris plant, refers to beetroot grown without synthetic pesticides or fertilizers, often processed into juice or powder form. This supplement is primarily valued for its high content of inorganic nitrate (NO3−), which the body converts into nitric oxide (NO). Nitric oxide is a potent vasodilator, meaning it helps to widen blood vessels, thereby improving blood flow and oxygen delivery throughout the body. The main applications of organic beet supplementation include enhancing physical performance, particularly muscular endurance and strength, and reducing blood pressure. It is also being studied for its potential benefits in cardiovascular and metabolic health due to its antioxidant properties and ergogenic effects. Research on beetroot supplementation is moderately to highly mature, with numerous randomized controlled trials (RCTs) and systematic reviews supporting its efficacy, though variability can exist based on dosage and population.

Benefits

Certified organic beet offers several evidence-based benefits, primarily driven by its nitrate content. A meta-analysis of 27 RCTs demonstrated a small but significant improvement in muscular endurance (standardized mean difference [SMD] = 0.31; 95% CI: 0.10 to 0.51; p < 0.01) with beetroot supplementation. For muscular strength, a small overall effect (SMD = 0.26; 95% CI: 0.03 to 0.48; p < 0.05) was observed, with a more pronounced effect in fatigued states (SMD = 0.64; 95% CI: 0.25 to 1.03; p < 0.01). Furthermore, systematic reviews consistently show reductions in both systolic and diastolic blood pressure, often by 4-8 mmHg, which is clinically relevant. These cardiovascular benefits are attributed to nitrate-induced nitric oxide production. While less robust, there is also some evidence suggesting possible antioxidant and neuroendocrine benefits. Healthy adults, including athletes and individuals with elevated blood pressure, are the primary beneficiaries, with effects observed acutely within hours of ingestion or over short-term supplementation periods (days to weeks).

How it works

The primary mechanism of action for certified organic beet involves the nitrate-nitrite-nitric oxide pathway. Dietary nitrate (NO3−) from beetroot is first converted to nitrite (NO2−) by anaerobic bacteria residing in the mouth. This nitrite is then absorbed into the bloodstream and can be further reduced to nitric oxide (NO) in various tissues, particularly under conditions of low oxygen. Nitric oxide acts as a signaling molecule, promoting vasodilation by relaxing vascular smooth muscle, which leads to improved blood flow, reduced blood pressure, and enhanced oxygen and nutrient delivery to muscles. This improved oxygen supply and mitochondrial efficiency contribute to enhanced muscular performance and endurance. The efficacy of beetroot is dependent on an intact oral microbiota, as evidenced by the reduced effects when antibacterial mouthwash is used.

Side effects

Certified organic beet is generally considered safe, with no serious adverse effects reported in randomized controlled trials. The most common side effect, occurring in more than 5% of individuals, is mild gastrointestinal discomfort, which may include stomach upset or bloating. An uncommon side effect (1-5%) is beeturia, characterized by red or pink urine and/or stool, which is a harmless phenomenon resulting from the excretion of betalain pigments found in beets. No significant rare adverse events (less than 1%) have been reported. However, caution is advised regarding potential drug interactions: beetroot supplementation may have an additive blood pressure-lowering effect when combined with antihypertensive medications, necessitating medical supervision. Contraindications include individuals with hypotension or those using nitrate medications for angina, as the combined vasodilatory effects could be excessive. Data on the safety of beetroot supplementation in special populations such as pregnant women, children, or individuals with severe cardiovascular disease are limited, and its use in these groups should be approached with caution and under medical guidance.

Dosage

For optimal benefits, the minimum effective dose of nitrate from certified organic beet is approximately 300-500 mg, typically equivalent to about 70 ml of concentrated beetroot juice. The optimal daily dosage range for both ergogenic and blood pressure-lowering effects is between 6-12 mmol of nitrate. While no established maximum safe dose exists, doses up to 12 mmol have been well tolerated in studies. For acute effects, such as enhancing exercise performance, it is recommended to time supplementation approximately 2-3 hours before exercise, as the peak effects occur within this timeframe. Concentrated beetroot juice or powder standardized for nitrate content is preferred over whole beetroot due to better dose control and consistency. It is important to note that the oral nitrate reduction process requires an intact oral microbiota; therefore, the use of antibacterial mouthwash can reduce the efficacy of beetroot supplementation. No specific cofactors are required, but consistent dietary intake is recommended for sustained benefits.
