Nitric Oxide and Beet Root: The Cardiovascular Ingredient You're Overlooking

The Nitrate-Nitrite-Nitric Oxide Pathway

Beet root is one of the richest dietary sources of inorganic nitrate. When you consume nitrate-rich foods, the conversion pathway is elegant: dietary nitrate (NO3-) is reduced to nitrite (NO2-) by bacteria on the tongue, then further converted to nitric oxide (NO) in the stomach and tissues. This process, known as the enterosalivary pathway, was described in detail by Lundberg et al. (2008) in a review published in Nature Reviews Drug Discovery.

What makes this pathway significant is that it provides an alternative route to nitric oxide production that doesn't rely on the enzymatic pathway (nitric oxide synthase, or NOS). The NOS pathway becomes less efficient with age, during periods of oxidative stress, and in individuals with cardiovascular risk factors. The dietary nitrate pathway effectively bypasses these limitations, which is why researchers have become increasingly interested in nitrate-rich foods as a strategy to support cardiovascular function.

Blood Flow and Exercise Performance

Nitric oxide's primary cardiovascular function is vasodilation. When NO is produced, it signals the smooth muscle cells lining blood vessels to relax, widening the vessels and reducing resistance to blood flow. This has direct implications for exercise performance and recovery.

Jones et al. (2018) published a comprehensive review in the Annual Review of Nutrition examining the effects of dietary nitrate on exercise performance. The research showed that beet root juice supplementation may reduce the oxygen cost of submaximal exercise by 5-7%, effectively making movement more metabolically efficient. Studies also indicated improvements in time-to-exhaustion during high-intensity exercise and enhanced performance in intermittent sprint protocols.

Bailey et al. (2009) published one of the foundational studies in the Journal of Applied Physiology, demonstrating that dietary nitrate supplementation from beet root juice reduced systolic blood pressure and decreased the oxygen cost of moderate-intensity exercise in healthy adults. The researchers attributed these effects to improved mitochondrial efficiency and enhanced blood flow to working muscles.

For recovery specifically, improved blood flow means more efficient delivery of nutrients and oxygen to damaged tissues, and faster clearance of metabolic waste products generated during intense exercise. This is why beet root is more than a pre-workout ingredient — it supports the entire recovery process.

Why Beet Root Complements Tart Cherry

CHRY's formula pairs 200mg of beet root with 500mg of tart cherry, and the combination is intentional. These two ingredients address recovery through complementary mechanisms.

Tart cherry is rich in anthocyanins — polyphenolic compounds that research suggests may support the body's natural inflammatory response after exercise. Howatson et al. (2010) published findings in the Scandinavian Journal of Medicine and Science in Sports showing that Montmorency tart cherry juice consumption was associated with faster recovery of isometric muscle strength following a marathon.

Beet root, meanwhile, works on the vascular side. By supporting nitric oxide production, it may help ensure that blood flow to recovering tissues remains optimal. Think of it this way: tart cherry may help manage the body's response to exercise-induced muscle stress, while beet root may help ensure that the circulatory system is delivering what those muscles need to rebuild.

Clifford et al. (2017) published a study in the European Journal of Nutrition examining beet root juice's effects on recovery from eccentric exercise. The study found that beet root supplementation was associated with attenuated muscle soreness and faster recovery of countermovement jump performance. The researchers suggested that nitric oxide-mediated improvements in blood flow may have facilitated the recovery process.

Cardiovascular Support Beyond Exercise

The benefits of dietary nitrate extend well beyond the gym. Siervo et al. (2013) conducted a systematic review and meta-analysis published in The Journal of Nutrition that examined the effects of inorganic nitrate and beet root supplementation on blood pressure. The analysis found that dietary nitrate supplementation was associated with significant reductions in systolic blood pressure, with larger effects observed in individuals with higher baseline blood pressure values.

Kapil et al. (2015) published a randomized, double-blind, placebo-controlled trial in Hypertension showing that daily beet root juice supplementation over four weeks was associated with sustained reductions in blood pressure and improvements in endothelial function. The study provided evidence that dietary nitrate may support cardiovascular health through mechanisms that go beyond acute vasodilation — including potential effects on arterial stiffness and platelet function.

For anyone interested in long-term health — not just athletic performance — these findings suggest that regular dietary nitrate intake may be a meaningful component of cardiovascular wellness. And unlike many supplements that require large doses, the amounts used in research are consistent with what can be obtained through dietary sources and moderate supplementation.

The Evening Timing Advantage

Most beet root products are marketed as pre-workout supplements. But there's a case to be made for evening consumption as well. Blood pressure naturally dips during sleep — a phenomenon called nocturnal dipping — and supporting healthy nitric oxide levels in the evening may complement this natural cardiovascular rhythm.

Additionally, the recovery processes that happen during sleep — muscle repair, glycogen replenishment, hormonal regulation — all benefit from adequate blood flow. By including beet root in an evening recovery formula alongside magnesium glycinate (which may support vascular relaxation through its own mechanisms), CHRY is designed to support the circulatory conditions that facilitate overnight recovery.

The Bottom Line

Beet root isn't glamorous. It doesn't have the name recognition of creatine or the trendiness of adaptogens. But the science behind dietary nitrate and nitric oxide production is robust, well-replicated, and directly relevant to both exercise recovery and long-term cardiovascular health.

CHRY includes 200mg of beet root alongside tart cherry, creatine monohydrate, magnesium glycinate, L-theanine, and apigenin — creating a formula that addresses recovery from multiple physiological angles. Better blood flow. Better nutrient delivery. Better recovery conditions while you sleep.
