The Science of Nitric Oxide: How Dietary Nitrates Work in the Body
Unlike pre-workouts that rely on artificial stimulants to raise heart rate, beet root powder relies on human biochemistry. Beets are one of nature's richest sources of inorganic dietary nitrate (NO3−). When consumed, the human body transforms these nitrates into nitric oxide (NO) through a biological sequence known as the enterosalivary nitrate-nitrite-nitric oxide pathway:
Oral Bioconversion: You drink the beet powder. Specialized beneficial bacteria located on the surface of your tongue convert nitrate (NO3−) into bioactive nitrite (NO2−).
Gastric Activation: After swallowing, stomach acid further processes nitrite, sending it into your systemic circulation.
Systemic Vasodilation: In your blood vessels and tissues—especially during exercise or physical exertion—nitrite is converted into nitric oxide. Nitric oxide signals vascular smooth muscle to relax, widening blood vessels (vasodilation) and allowing oxygen-rich blood to circulate efficiently with lower resistance.
Key Peer-Reviewed Clinical Evidence
Vascular and Blood Pressure Support: A landmark clinical trial published in Hypertension demonstrated that dietary nitrate from red beets led to substantial acute reductions in systolic blood pressure within hours of ingestion, alongside preserved endothelial function and reduced platelet hyperactivity (Webb et al., 2008, Hypertension, 51(3):784-790).
Meta-Analytic Consensus: A systematic review and meta-analysis published in The Journal of Nutrition examined 16 randomized clinical trials and concluded that dietary inorganic nitrate significantly and consistently lowers systolic blood pressure in human subjects across multiple age groups (Siervo et al., 2013, J Nutr, 143(6):818-826).
Exercise Efficiency and Stamina: Peer-reviewed research in sports physiology confirmed that dietary nitrate reduces the oxygen cost of submaximal exercise, enhancing mitochondrial respiration efficiency and extending time-to-exhaustion in athletes (Jones, 2014, Sports Med, 44(Suppl 1):S35-S45).
Firsthand Retailer Insights: What Over 31 Years in Supplement Retail Taught Us
At VitaNet, our team has guided supplement consumers since 1995. We have evaluated thousands of formulations, and we know that textbook information does not always match real-world daily use. Here are critical practical factors you must know before taking beet root powder:
✓ Practical Warning: Never Use Antiseptic Mouthwash Right After Beet Powder
Most consumers are unaware that strong chlorhexidine or alcohol-based mouthwashes kill the beneficial oral bacteria on the tongue responsible for converting nitrate into nitrite. Clinical research indicates that antibacterial mouthwash can eliminate the blood pressure-lowering and nitric oxide-generating benefits of dietary nitrates by up to 90% (Kapil et al., 2013, Free Radic Biol Med, 55:93-100). If you rinse your mouth, do so with plain water.
✓ Timing Secrets: Take It 2 to 3 Hours Ahead, Not 10 Minutes Before Exercise
Unlike caffeine, which hits your bloodstream in 15 minutes, the enterosalivary nitrate pathway takes time. Clinical pharmacokinetics confirm that circulating plasma nitrite peaks between 2 and 3 hours post-ingestion. To get peak muscular oxygenation or cardiovascular support for an afternoon workout or race, drink your scoop two hours prior.
Many trendy "beet gummies" contain negligible beet amounts mixed with 4 to 6 grams of processed cane sugar and artificial flavors. NOW Foods 12 oz Beet Root Powder is pure dried whole vegetable matter. It preserves the natural betaine (trimethylglycine), minerals, and insoluble fibers that support cellular osmolyte balance and liver methylation alongside nitric oxide.
Because beets grow directly inside topsoil, they naturally absorb minerals from the earth. Unfortunately, if an agricultural supplier grows beets in contaminated soil, the root also bioaccumulates toxic heavy metals such as lead, cadmium, and arsenic. This makes third-party and in-house analytical safety testing paramount for any root supplement.
NOW Foods maintains one of the largest and most sophisticated private analytical testing laboratories in North America, certified under strict ISO/IEC 17025 standards. Every incoming raw ingredient batch and finished product lot must clear uncompromising screening protocols:

Who Should Take Beet Root Powder – And Important Precautions
Honest nutritional guidance requires identifying not only who benefits from a supplement, but also who should proceed with caution:
Cardiovascular Maintenance: Adults seeking whole-food botanical support for arterial elasticity.
Active Seniors: Individuals seeking healthy blood flow support without relying on caffeine.
Precautions & Considerations:
Kidney Stones (Oxalates): Like spinach and Swiss chard, beets are naturally high in dietary oxalates. Those with a medical history of calcium-oxalate kidney stones should consult their doctor before taking daily concentrated beet powder.
Hypotensive Medications: Because dietary nitrates support vasodilation, anyone taking prescription blood pressure medications or PDE-5 inhibitors should consult their physician.
Beeturia (Harmless Red Tint): In 10% to 14% of people, beet pigments (betalains) pass through into urine or stool, causing a pinkish tint. This is harmless betacyanin excretion, not blood.
Suggested Usage & Palatable Flavor Blends
Standard Serving: Mix 1 level tablespoon (9.5 g) into 8 ounces of cold water, freshly squeezed juice, or your favorite workout shake. Drink immediately upon mixing.
Pure beet powder has an earthy, naturally sweet flavor. If you find the earthiness intense, our team at VitaNet recommends these retailer-tested kitchen pairings:
Citrus Boost: Blend with orange juice or fresh lemon water. Vitamin C works synergistically with plant phytonutrients to prevent nitrosamine formation and enhance palatability.
Post-Workout Berry Protein Smoothie: Blend 1 scoop with chocolate or vanilla whey/plant protein, unsweetened almond milk, and frozen berries. The berries mask earthiness completely.
Tart Cherry Endurance Cocktail: Mix 1 scoop with tart cherry juice and cold water 2 hours before a long training run for dual nitric oxide and antioxidant support.
Storage Tip: Because pure beet root contains natural plant sugars and has no anti-caking agents, close the lid tightly and store in a cool, dark, dry cabinet away from steam or humidity.

Frequently Asked Questions (FAQ)
How many whole beets are in one serving of NOW Sports Beet Root Powder?
Each 1 level tablespoon serving (approx. 9.5 g) provides the dried nutritional equivalent of 2.5 whole fresh beets (Beta vulgaris), concentrated without added sugars or extraction chemicals.
When is the best time to take beet root powder for workout performance?
Clinical research demonstrates that plasma nitrite peaks between 2 and 3 hours following dietary nitrate consumption. For optimal stamina, oxygen utilization, and vasodilation, drink your serving 2 to 3 hours prior to athletic exertion or heavy training.
Can beet root powder turn my urine or stool red?
Yes. This is a normal, harmless condition called beeturia. It occurs in roughly 10% to 14% of the population when the deep red betacyanin plant pigments pass through the digestive tract into the bladder or bowel. It is completely benign.
Why shouldn't I use mouthwash after drinking beet root powder?
The human body does not naturally produce the enzyme required to convert nitrate into nitrite; it relies on friendly oral bacteria residing on your tongue. Antiseptic mouthwashes eradicate these lingual microflora, wiping out the nitric oxide benefit by up to 90%. Avoid mouthwash for at least 3 hours after consumption.
How does NOW Foods ensure this powder is free from heavy metals?
NOW Foods tests every batch in in-house ISO/IEC 17025 accredited analytical laboratories. Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), they test for trace lead, arsenic, cadmium, and mercury down to parts-per-billion levels, ensuring the product adheres to strict safety thresholds.
Is NOW Beet Root Powder raw, non-GMO, and vegan?
Yes. NOW Beet Root Powder is 100% dried whole root powder with zero animal derivatives, binders, or artificial additives. It is Non-GMO Project Verified, Vegan, Halal, and Kosher certified.
