Also known as: Beet Fiber Complex, Beetroot Extract, Beta vulgaris Fiber, Beetroot Fiber

Overview

Beetroot fiber is derived from the root of the beet plant (*Beta vulgaris*), recognized for its high dietary fiber and bioactive compounds, particularly inorganic nitrates. This supplement is primarily aimed at enhancing athletic performance, improving cardiovascular health, and supporting digestive health. Research indicates moderate to high levels of evidence from randomized controlled trials showcasing its positive effects on endurance and muscle efficiency, although some studies face limitations such as small sample sizes and short duration. Beetroot fiber is available in various forms including juice and concentrated extracts, making it a versatile dietary supplement.

Benefits

Key benefits of beetroot fiber include significant enhancements in muscular endurance and strength, with systematic reviews indicating a Standardized Mean Difference (SMD) of 0.31 for endurance improvements. It is also associated with increased cardiorespiratory endurance, enhancing exercise efficiency and reducing oxygen consumption, particularly advantageous for athletes engaged in high-intensity activities. Moreover, the inorganic nitrates contribute positively to cardiovascular health by potentially regulating blood pressure and improving vascular function. Athletes often report substantial functional gains when supplementing with beetroot products leading up to performance activities.

How it works

The efficacy of beetroot fiber hinges on the conversion of inorganic nitrates into nitric oxide (NO) in the body. This conversion promotes enhanced blood flow and muscle oxygenation, resulting in a reduced oxygen cost during exercise and improved muscular contraction and relaxation via increased vascular efficiency. The involvement of the nitric oxide pathway is crucial for augmenting physical performance and endurance, especially in strenuous exercises, with effects peaking a few hours post-consumption.

Side effects

Beetroot fiber is generally safe when consumed in recommended amounts, though some users may experience common gastrointestinal issues such as bloating, gas, and stomach discomfort due to its high fiber content, affecting over 5% of users. Uncommon side effects arise in 1-5% of cases, generally mild and related to fiber intake. No severe side effects have been documented (<1%). Individuals on blood pressure medications should consult healthcare professionals due to possible interactions. While specific contraindications are lacking, those with severe gastrointestinal disorders or undergoing surgery should seek medical advice. Pregnant or breastfeeding women are also recommended to consult with healthcare providers prior to use.

Dosage

For optimal results, the recommended dosage of beetroot supplements typically ranges from 316 to 985 mg of inorganic nitrates daily. This dosage is best taken 2-3 hours before exercise to maximize the ergogenic effects. While no defined maximum dosage is established, extremely high intake may lead to increased gastrointestinal discomfort. Beetroot is available in various forms, such as juice and concentrated extracts, both of which allow for efficiently absorbed inorganic nitrates. Sufficient hydration is recommended to support absorption.
