Beet Root

Q: How often should I take beetroot supplements?

Typically, beetroot supplements are taken 2-3 hours before exercise to enhance performance. Consistent daily use is not necessary unless for chronic conditions like hypertension, under medical guidance.

Q: Is beetroot safe for everyone?

Beetroot is generally safe, but individuals with kidney issues or those on blood pressure medications should consult a healthcare provider before use to avoid potential complications.

Q: When is the best time to take beetroot?

The ideal time to take beetroot is 2-3 hours before exercise to maximize its ergogenic effects. This allows sufficient time for nitrate conversion to nitric oxide.

Q: What can I expect from beetroot supplementation?

Users can expect improved endurance and potential blood pressure reduction. Benefits are more pronounced in activities requiring sustained effort and cardiovascular function.

Q: Does beetroot improve all types of athletic performance?

No, beetroot's benefits are more pronounced in endurance and strength tasks. It may not significantly impact short-burst, anaerobic activities.

Also known as: Beetroot, Beets, Beta vulgaris

Overview

Beetroot, scientifically known as *Beta vulgaris*, is a root vegetable notable for its high nitrate content, which the body converts into nitric oxide. It is commonly used as a dietary supplement and functional food, primarily to enhance athletic performance and lower blood pressure. Beetroot is characterized by its rich antioxidant properties and vibrant color, attributed to betalain pigments. It is available in various forms, including whole beets, juice, powder, and capsules. Research suggests that beetroot supplementation can improve muscular and cardiorespiratory endurance. The nitrates in beetroot promote vasodilation, improving blood flow and oxygen delivery to muscles. While generally safe, it's important to be aware of potential side effects and interactions, especially for individuals with specific health conditions or those taking certain medications. The evidence supporting its benefits is growing, with systematic reviews and meta-analyses providing robust insights.

Benefits

Beetroot supplementation primarily enhances muscular and cardiorespiratory endurance. A systematic review indicated that beetroot-based supplements positively affect muscular endurance (SMD: 0.31; 95% CI: 0.10 to 0.51; *p* < 0.01) and strength, particularly in a fatigued state (SMD: 0.64; 95% CI: 0.25 to 1.03; *p* < 0.01). Athletes may experience improved endurance and performance due to increased efficiency and time to exhaustion. Additionally, beetroot may help lower blood pressure in hypertensive patients, with a meta-analysis showing that nitrate from beetroot juice can reduce systolic blood pressure by approximately 4.81 mmHg (95% CI: −8.82 to 0.80). The effect sizes for endurance and strength improvements are generally small to moderate but clinically significant in specific contexts. Benefits typically manifest within a few hours of consumption, especially when ingested 2-3 hours before exercise.

How it works

Beetroot's primary mechanism of action involves the conversion of its nitrates into nitric oxide (NO) in the body. This conversion enhances blood flow, improves mitochondrial efficiency, and increases oxygen delivery to muscles. Nitric oxide promotes vasodilation by acting on endothelial cells, activating guanylate cyclase, which leads to smooth muscle relaxation and improved cardiovascular function. The increased blood flow and oxygen supply enhance muscle contraction efficiency, contributing to improved endurance and performance. Nitrates from beetroot are well absorbed and readily converted to nitric oxide, making it an effective ergogenic aid.

Side effects

Beetroot is generally considered safe for most adults, but it can cause some side effects. The most common side effect is temporary discoloration of urine and feces (beeturia) due to its betalain content, which is harmless. Some individuals may experience gastrointestinal upset, such as bloating or diarrhea. Rare side effects are not well-documented. Beetroot may interact with medications that affect blood pressure or blood flow, so caution is advised for individuals taking such medications. Individuals with certain kidney conditions or those taking specific medications should consult a healthcare provider before using beetroot supplements. Pregnant or breastfeeding women should also seek medical advice before using beetroot supplements to ensure safety.

Dosage

The minimum effective dose of beetroot is typically around 300-400 mg of nitrates per day. Optimal dosage ranges are between 316-985 mg of nitrates per day, consumed 2-3 hours before exercise to maximize performance benefits. While a maximum safe dose is not well established, high doses may cause gastrointestinal upset. Beetroot juice or supplements are commonly used, and absorption is generally good but may vary based on individual factors. It is best taken before exercise or athletic events to enhance endurance and performance. No specific cofactors are required for its effectiveness.
