Also known as: beetroot, beets, red beet, garden beet, table beet, sugar beet, Beta vulgaris
Overview
Beetroot, scientifically known as Beta vulgaris, is a nutrient-dense root vegetable with a deep red-purple color. It is particularly valued for its high content of dietary nitrates, which are converted into nitric oxide (NO) in the body, yielding various health benefits. Beetroot is commonly linked with enhanced athletic performance due to improved oxygen efficiency, lower blood pressure, and support for cognitive health, especially in aging populations. Rich in antioxidants such as betalains and flavonoids, it can be consumed in various forms, including juice, powder, and whole root. Extensive research, including randomized controlled trials and meta-analyses, supports beetroot's effectiveness as a dietary supplement, making it popular among athletes and health-conscious individuals alike.
Benefits
Beetroot supplementation provides several evidence-backed benefits. It is particularly effective in improving athletic performance, with studies indicating a 1.31% improvement in time trial outcomes (Jones et al., 2018). Additionally, beetroot has been associated with a significant reduction in systolic blood pressure (around 4.4 mmHg), providing notable benefits for those with hypertension (Kapil et al., 2013). Cognitive enhancements have also been reported in older adults experiencing mild cognitive decline, attributed to regular consumption of beetroot juice (Presley et al., 2011). The strength of evidence from these studies highlights beetroot's potential as a beneficial health supplement, especially for athletes and those managing cardiovascular issues.
How it works
Beetroot's health effects primarily stem from dietary nitrates, which are converted to nitric oxide (NO) in the body—a potent vasodilator. NO plays a crucial role in enhancing blood flow, reducing blood pressure, and improving oxygen delivery to tissues during exercise. It achieves these effects by relaxing vascular smooth muscle, promoting better endothelial function, and increasing levels of cyclic guanosine monophosphate (cGMP) through stimulation of soluble guanylate cyclase. This biochemical cascade is key to beetroot's contributions to athletic performance and overall cardiovascular health.
Side effects
Beetroot is typically considered safe for most individuals when consumed in moderate amounts. The most common side effects, affecting over 5% of users, include beeturia, which is the harmless pink or red coloration of urine, and mild gastrointestinal upset. Serious adverse effects are rare (less than 1%). Precaution is advised for individuals on antihypertensive medications or blood thinners, as beetroot can intensify their effects, potentially leading to significantly lowered blood pressure. Additionally, those with a history of kidney stones should be cautious with nitrate intake due to its effects on oxalate metabolism. Pregnant or breastfeeding women are encouraged to consult with healthcare providers before beginning supplementation.
Dosage
The minimum effective dose for beetroot juice supplementation is around 500 mg, which provides approximately 250 mg of nitrates per day. For optimal effects, especially in enhancing athletic performance, a dosage of 500-1000 mg of beetroot juice, or 250-500 mg of nitrates daily, is recommended. Although there is no established maximum safe dose, exceeding 1000 mg of nitrates may lead to gastrointestinal discomfort. Athletes should ideally consume beetroot products about 2-3 hours prior to exercising. For cardiovascular benefits, consistent daily consumption is encouraged. Variability in absorption rates across different beetroot formulations should be taken into consideration, along with the potential synergistic effects of combining beetroot with antioxidant-rich foods.
FAQs
Is beetroot safe to consume?
Yes, beetroot is generally safe but may cause mild side effects like beeturia or gastrointestinal upset in some individuals.
When should I take beetroot supplements?
For athletic results, consume 2-3 hours before exercise. For cardiovascular benefits, include it regularly in your diet.
What results can I expect from beetroot supplementation?
Benefits may include improved athletic performance and reduced blood pressure within hours to days of regular consumption.
Does beetroot increase muscle strength?
No, beetroot does not directly increase muscle strength but enhances exercise efficiency by reducing oxygen consumption.
