Beet Root Concentrate

Also known as: Beta vulgaris, Beetroot, Beetroot juice, Beetroot concentrate

Overview

Beetroot concentrate, derived from *Beta vulgaris*, is a dietary supplement primarily used to enhance exercise performance and recovery. Its active component, nitrate, converts into nitric oxide in the body, potentially improving blood flow and reducing oxygen consumption during exercise. Available in various forms, including juice and concentrated powders, beetroot is a rich source of vitamins, minerals, and antioxidants. Research indicates that beetroot concentrate may improve endurance and reduce muscle fatigue, making it popular among athletes. However, the quality of evidence varies, and individual responses can differ. While generally safe, it's essential to be aware of potential side effects and interactions, especially for individuals with specific health conditions or those taking certain medications. Beetroot's benefits are linked to its ability to boost nitric oxide levels, supporting vascular function and overall exercise capacity.

Benefits

Beetroot concentrate primarily enhances exercise performance by improving endurance and reducing oxygen consumption. Studies show it aids in the recovery of muscular strength after fatigue, with significant effects on isometric strength recovery and countermovement jump performance (SMD approximately 0.64). Some research suggests benefits in reducing muscle soreness and improving pressure pain thresholds, though effects on oxidative stress markers are inconsistent. Athletes and individuals engaging in high-intensity exercise may benefit most from improved endurance and recovery. The standardized mean difference (SMD) for muscular endurance is approximately 0.31, indicating a small but significant effect. Benefits are typically observed within 24-72 hours post-exercise.

How it works

Beetroot concentrate's primary mechanism involves the conversion of dietary nitrates to nitric oxide. This conversion enhances blood flow and reduces oxygen consumption during exercise. Nitric oxide improves vascular function, potentially enhancing exercise performance by increasing blood flow to muscles. Key molecular targets include nitric oxide synthase and endothelial function. Nitrates from beetroot are well absorbed, with bioavailability influenced by factors like gut bacteria and dietary components. This process supports improved oxygen delivery and utilization in muscles, leading to enhanced endurance and reduced fatigue.

Side effects

Beetroot concentrate is generally considered safe for most adults. Common side effects include red urine (beeturia) and gastrointestinal upset in some individuals. Allergic reactions are rare but possible. Potential interactions with medications for blood pressure or diabetes exist due to vasodilatory effects. Individuals with certain kidney conditions or those taking medications should consult a healthcare provider before use. Pregnant or breastfeeding women should also consult healthcare providers before use. High doses may cause gastrointestinal discomfort. It's important to start with lower doses to assess tolerance and monitor for any adverse reactions.

Dosage

The minimum effective dose is typically around 300-400 mg of nitrate per serving. Optimal dosage ranges are 500-600 mg of nitrate for exercise performance benefits. The maximum safe dose is not well established, but high doses may cause gastrointestinal upset. It is best taken 2-3 hours before exercise. Beetroot juice is commonly used due to its high nitrate content. Absorption may be influenced by gut health and other dietary factors. No specific cofactors are required. Individual responses may vary, so it's advisable to start with a lower dose and adjust as needed.

FAQs

What are the practical considerations for using beetroot concentrate?

Beetroot concentrate can be consumed as a juice or supplement. Be aware that it may cause red urine due to its betalain content, which is harmless. Ensure you are sourcing your beetroot from a reputable supplier.

Is beetroot concentrate safe for everyone?

Generally safe, but individuals with certain health conditions, such as kidney issues, or those taking blood pressure medications should consult a healthcare provider before use to avoid potential complications.

When is the best time to take beetroot concentrate for exercise?

For optimal performance benefits, it is best to take beetroot concentrate 2-3 hours before exercise. This allows sufficient time for the body to convert nitrates into nitric oxide and enhance blood flow.

What results can I expect from taking beetroot concentrate?

You can expect improved endurance and recovery, though individual responses may vary. Some studies show it does not significantly alter body composition or improve high-intensity interval training performance in all cases.

Research Sources

https://pubmed.ncbi.nlm.nih.gov/34151694/ – This systematic review and meta-analysis of nine studies (six in the meta-analysis) involving adult humans found that beetroot juice accelerates isometric strength recovery and improves countermovement jump performance within 168 hours post-exercise. However, the authors noted concerns for risk of bias across the included studies, leading to a moderate quality assessment of the evidence.
https://pubmed.ncbi.nlm.nih.gov/36847169/ – This systematic review and meta-analysis of twelve RCTs involving various populations concluded that beetroot or nitrate supplementation does not significantly alter body composition indices. The certainty of evidence was rated as low to moderate due to heterogeneity and bias concerns, suggesting that the effects of beetroot on body composition are not well-supported.
https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2024.1347242/full – This systematic review of seventeen studies involving athletes and non-athletes examined the effects of beetroot supplementation on high-intensity interval training. The review found no significant improvement in peak or mean power output, highlighting the variability in exercise protocols and supplementation strategies as limitations, resulting in a moderate quality evidence assessment.
https://pubmed.ncbi.nlm.nih.gov/37167368/ – This study investigates the impact of dietary nitrate supplementation, primarily through beetroot juice, on exercise performance and cardiovascular function. The findings suggest that nitrate supplementation can enhance exercise efficiency by reducing oxygen demand and improving blood flow, particularly during endurance activities. This highlights the potential benefits for athletes and individuals seeking to improve their cardiovascular health.
https://pubmed.ncbi.nlm.nih.gov/34835931/ – This research explores the effects of beetroot juice supplementation on muscle recovery following strenuous exercise. The results indicate that beetroot juice can accelerate the recovery of muscle function, reduce muscle soreness, and improve pressure pain thresholds. These findings suggest that beetroot juice may be a valuable tool for athletes and individuals looking to optimize their post-exercise recovery.
