Beet-Free Nitric Oxide Supplement: A Dose-Transparent Nitrate Drink Mix for Adults 45–70

Quick answer: A beet-free nitric oxide supplement supplies dietary nitrate from a source other than beets, such as spinach. Your body converts that nitrate to nitrite and then to nitric oxide, without the earthy taste, beet sugar, or pink urine (beeturia) some people get from beets. NITRATE-IQ™ is a beet-free, dose-transparent, lemon-flavored drink mix for health-conscious adults 45–70. Its spinach extract is standardized to 9% dietary nitrate, so the label states the exact amount in every serving: 135 mg in 1 scoop, 270 mg in 2 scoops, and 540 mg in 4 scoops. It is designed to support healthy nitric-oxide levels, circulation, and blood pressure already within the normal range.*

Here’s something that’s easy to miss in the nitric-oxide aisle: the reason people reach for beets was never really the beets. It’s dietary nitrate. And unlike a beet, nitrate can be measured. If there’s a half-used tub of beet powder in your cupboard, given up on because of the earthy taste, the chance of beeturia, or a label that never said how much nitrate you were getting, this guide is for you.

NITRATE-IQ™ gets its dietary nitrate from Nitrate Burst™ spinach extract (Spinacia oleracea leaf), standardized to 9% dietary nitrate and 13% naturally occurring potassium. That means no beeturia, no beet sugar, and a lemon flavor instead of an earthy beet taste. The 2-scoop serving listed on the label also provides 150 mg of Enovita™ grape-seed extract, half the 300 mg/day used in its 16-week clinical trial. In short-term trials, mostly in healthy adults and at an average of roughly 500 mg of nitrate, dietary nitrate was associated with a 4.4 mmHg lower systolic reading (Siervo et al., 2013). With the dose printed on the label, you know exactly what each serving provides.*

What Is NITRATE-IQ™ and Who Is It For?

One simple scoop. An exact milligram dose you can see on the label. That’s how nitric-oxide support should have worked all along.

NITRATE-IQ™ is a beet-free, precision-dosed nitrate drink mix that Triquetra Health developed for a specific person: the health-conscious adult, 45 to 70, who reads labels and wants to support healthy circulation without the earthy taste, beeturia, and undisclosed dosing of many beet products. Each serving combines a standardized green spinach extract with Enovita™ grape-seed extract (standardized to 95% oligomeric proanthocyanidins, or OPCs) and a small amount of fulvic acid in a two-part nitric-oxide formula. Dietary nitrate, the active ingredient class in NITRATE-IQ™, has been studied in meta-analyses of randomized controlled trials (Siervo et al., 2013; Norouzzadeh et al., 2025). Its Enovita™ grape-seed extract has been studied in a 16-week randomized, placebo-controlled trial at 300 mg/day, twice the 2-scoop amount (Schön et al., 2021). What that trial did and didn’t find is covered in the research section below.

Here’s the idea in one sentence.  NITRATE-IQ™ pairs standardized green spinach extract, a measured source of dietary nitrate, with Enovita™ grape-seed extract, whose proanthocyanidins have shown eNOS and antioxidant activity in laboratory (cell-culture) research.*

Why Do So Many Adults Give Up on Beet Supplements?

You read labels. You pay attention to your heart health and to your numbers at checkups, and you’d rather be proactive about cardiovascular wellness. So you tried a beet product, and you hit a wall: the earthy taste, the chance of beeturia, and a label that never disclosed its nitrate dose. It tasted like dirt. Beeturia, where beets turn urine pink or red, is estimated to occur in about 10–14% of people and has been reported more often in people with low iron (Watts et al., 1993). And the label told you nothing about how much nitrate you were actually getting.

That’s more than an inconvenience. When a supplement is unpleasant, you stop taking it, and the half-used tub turns into a small daily reminder that you gave up on something you cared about. When the label hides the dose, you’re dosing blind, which makes it hard to build a routine you can trust. And if you read labels carefully, “proprietary blend” isn’t a reason to buy. It’s a reason to distrust.

None of that is a discipline problem. Your last supplement didn’t fail because nitrate doesn’t work. It failed because it was a beet product you couldn’t taste past and a dose you couldn’t see. So what if you kept the well-studied nitric-oxide pathway and changed everything about the delivery?

What Do Many Beet Powders Leave Out?

The nitric-oxide category moved faster than many of its products did. The mechanism is well studied, yet many popular formats still lean on a single ingredient sourced from beets, often without a stated nitrate dose. Two limitations follow from that.

A hidden dose. Beet powders deliver genuine dietary nitrate and helped popularize this category. But many list only “beetroot powder” and state no nitrate milligrams, so you can’t match a dose to published research or build a repeatable routine. For label readers, that’s a real problem, especially since the beet source can also bring the earthy taste, the chance of beeturia, and beet sugar. NITRATE-IQ™ takes the opposite approach: it uses standardized spinach nitrate and prints the exact dose on the label, so you know what each serving delivers.

A single pathway. Arginine and citrulline products can raise nitric oxide, but they work through the oxygen-dependent eNOS pathway, one that age and oxidative stress can blunt (Torregrossa et al., 2011). Much of an oral arginine dose is also broken down before it reaches circulation; in one pharmacokinetic study, absolute bioavailability was about 20% (Tangphao et al., 1999). NITRATE-IQ™ works primarily through a different route, the nitrate-nitrite-nitric oxide pathway, and adds Enovita™ grape-seed extract as the formula’s second part.

Put those together and the pattern is hard to miss. Many products in this category offer a nitrate source they don’t measure. What’s missing isn’t a better beet. It’s a two-part nitric-oxide formula with the dose printed on the label.

How Does Spinach Nitrate Become Nitric Oxide?

The idea here isn’t a new molecule. It’s supplying a well-studied one in a known amount. Picture a relay race your body already knows how to run.

Step one: supply the nitrate. Standardized green spinach extract supplies dietary nitrate to the enterosalivary pathway. Up to about a quarter of circulating nitrate is taken up by your salivary glands (Lundberg et al., 2008). In the mouth, friendly oral bacteria reduce it to nitrite, which can then be converted to nitric oxide in the acidic stomach and in low-oxygen conditions, such as working muscle. Nitrate hands the baton to nitrite; nitrite hands it to nitric oxide.

Step two: help vessels relax. Nitric oxide switches on the sGC/cGMP system, which relaxes the smooth muscle in blood-vessel walls so vessels widen (Lundberg et al., 2008). Think of loosening a kinked garden hose so water flows more freely. The spinach extract also contains naturally occurring potassium, a mineral the body needs for normal heart and muscle function (National Institutes of Health, Office of Dietary Supplements, 2021). At 390 mg per 2 scoops (8% DV), it’s a small contribution, not the driver of the formula.

Step three: the grape-seed side. Nitric oxide is short-lived; it reacts with superoxide, a reactive oxygen species, at a near diffusion-limited rate (Beckman & Koppenol, 1996). In laboratory (cell-culture) research, Enovita™ increased activated eNOS, the enzyme that makes nitric oxide in blood-vessel linings (Schön et al., 2021), and grape-seed proanthocyanidins in general have shown free-radical-scavenging activity (Bagchi et al., 2000). We’re not aware of published human studies of this protective effect, so we describe it as laboratory research only.

Why the dose on the label matters. Many beet-based products list only “beetroot powder” and state no nitrate milligrams. NITRATE-IQ™’s spinach extract is standardized to 9% dietary nitrate, which makes the number on the label a specification rather than an estimate: 135 mg in 1 scoop, 270 mg in 2 scoops, and 540 mg in 4 scoops. The 2-scoop serving (270 mg) falls within the range of doses studied in dietary-nitrate research, where larger doses were generally associated with larger effects (Siervo et al., 2013; Norouzzadeh et al., 2025). It is below the roughly 500 mg a day that the newest dose-response analysis linked with a 2 mmHg change (Norouzzadeh et al., 2025). One scoop (135 mg), the labeled daily direction, is an entry-level amount; it is below the doses most often used in blood-pressure research. If you’re curious, at-home saliva test strips can show the pathway responding. They show salivary nitrite only and don’t measure blood pressure or circulation.

Nitric oxide is the signaling molecule that tells your arteries to relax and widen, and the body’s own production of it tends to decline with age (Torregrossa et al., 2011). At the 2-scoop serving,  NITRATE-IQ™ provides 270 mg of dietary nitrate, which feeds the body’s nitric-oxide pathway that helps blood vessels relax, to support healthy circulation and blood pressure already within the normal range.*

 

What Does a Two-Part Nitric-Oxide Formula Mean for Your Daily Routine?

Mechanisms only matter for what they change in an ordinary day. Here’s how that tends to show up in real life.

A Measured, Repeatable Routine

Every 2-scoop serving delivers the same 270 mg of dietary nitrate, so your routine is built on a known input rather than a guess.

Instead of guessing, you have a measured morning routine with a known dose, and a clear, informed conversation to have with your healthcare provider at your next checkup.

You become the health-conscious adult who’s doing something deliberate, with a known dose, for your cardiovascular wellness. Proactive, not passive. An active participant in your own care.

A Routine You Actually Keep

The nitrate comes from spinach, not beets, in a lemon-flavored drink mix. So there’s no beeturia, no beet sugar, and no earthy beet taste.

The quiet guilt of another abandoned tub gets replaced by a routine that’s easy to stick with. Adherence gets easier when there’s no earthy beet taste to work around.

You become someone who sustains healthy habits instead of starting and quitting them. The person who finally found the tub that stays on the counter.

A Dose You Can See and Adjust

Because the spinach extract is standardized to 9% dietary nitrate, each serving is a specification you control, not a mystery you accept: 135 mg, 270 mg, or 540 mg.

The frustration of being kept in the dark by a proprietary blend gives way to the confidence of seeing exactly what each serving provides.

You become the label-literate expert running a smart, repeatable routine, supporting healthy nitric-oxide levels and daily vitality on your own terms.*

What Does the Research Say About Dietary Nitrate and Grape-Seed Extract?

Confidence should be earned, not asserted. One thing to keep in mind as you read this section: this is ingredient and mechanism research, not research on the finished product, and it isn’t a claim that NITRATE-IQ™ treats anything. Where a study was conducted or sponsored by an ingredient supplier, we say so.

Dietary nitrate and healthy blood pressure (meta-analysis). Study design: systematic review and meta-analysis of 16 randomized, placebo-controlled crossover trials (n=254), lasting 2 hours to 15 days, at an average dose of roughly 500 mg nitrate. Key finding: in these short-term trials, mostly in healthy adults, dietary nitrate was associated with a 4.4 mmHg lower systolic reading (95% CI −5.9 to −2.8, p<0.001), and higher daily nitrate doses were linked with larger systolic changes. The authors noted that the findings need to be tested in long-term trials. Why it matters: it shows the nutrient NITRATE-IQ™ delivers has a real, dose-related association with systolic readings. The 2-scoop serving (270 mg) sits toward the lower end of the doses studied. Citation: Siervo et al. (2013), The Journal of Nutrition.

Dietary nitrate dose-response (meta-analysis). Study design: GRADE-assessed systematic review and dose-response meta-analysis of 75 randomized controlled trials (n=1,823). Key finding: plasma nitrate and nitrite rose with dose, and blood pressure fell modestly as dose increased, by about 0.3–0.5 mmHg systolic per millimole (62 mg) of nitrate. The authors estimated that about 8 mmol (roughly 500 mg) a day is needed for a 2 mmHg change, and they called for more high-quality, population-specific studies. Why it matters: it’s the broadest current look at how much nitrate matters. The 2-scoop serving (270 mg) is below that 8 mmol estimate. Citation: Norouzzadeh et al. (2025), Nutrition Journal.

Medium-term nitrate and how readings are measured (meta-analysis). Study design: meta-analysis of 13 randomized, placebo-controlled trials lasting 1–6 weeks, n=325. Key finding: dietary nitrate was associated with a 4.1 mmHg lower systolic reading in resting clinic measurements, but no significant change was seen in 24-hour ambulatory or home monitoring. Why it matters: it shows the clearest evidence is for resting clinic readings. These trials did not find changes in 24-hour or home readings. Citation: Ashor et al. (2017), Journal of Hypertension.

Spinach-source nitrate and endothelial function (randomized crossover). Study design: randomized crossover trial in 30 healthy adults; a single meal of 200 g whole spinach providing about 180 mg nitrate. Key finding: compared with a control meal, spinach increased nitric-oxide status markers, plasma nitrite and flow-mediated dilation, and was associated with lower systolic readings; adding flavonoid-rich apple didn’t produce an additive effect. Why it matters: it shows nitrate from spinach, not only beetroot, can support nitric-oxide status and healthy vascular function.  NITRATE-IQ™ uses a spinach extract rather than whole spinach. Citation: Bondonno et al. (2012), Free Radical Biology and Medicine.

Spinach nitrate in midlife and older adults (randomized crossover). In 26 adults aged 38–69, a meal providing 220 mg nitrate from spinach increased large-artery elasticity and lowered systolic pressure and pulse pressure over the following hours compared with a low-nitrate meal. Citation: Liu et al. (2013), Nitric Oxide.

Enovita™ grape-seed extract (randomized, placebo-controlled trial). Study design: randomized, double-blind, placebo-controlled trial in 80 adults aged 40–70, 300 mg/day (two 150 mg tablets) for 16 weeks. Participants’ screening readings were above the normal range, so results may not apply to people whose readings are already normal. Key finding: systolic pressure fell in both the grape-seed and placebo groups, and the overall difference between groups was not statistically significant. In a subgroup of men, the grape-seed group showed a larger systolic difference than placebo at weeks 8 and 16. In separate cell-culture experiments, the extract increased activated eNOS and reduced endothelin-1 and sICAM-1 release. The study was conducted with the ingredient’s supplier (Indena). Why it matters: it is the main human trial on this branded extract. The studied 300 mg/day dose is reached at 4 scoops; the 2-scoop serving provides 150 mg. Citation: Schön et al. (2021), Nutrients.

Grape-seed extract more broadly (meta-analysis). Across 19 controlled trials of grape-seed extracts in general (not Enovita™ specifically), results were mixed: a modest diastolic difference was reported, with no significant effect on systolic pressure or flow-mediated dilation. Citation: Foshati et al. (2022), Pharmacological Research.

Quality and manufacturing. NITRATE-IQ™ is GMP manufactured, in line with FDA’s dietary supplement current good manufacturing practice regulations (21 CFR Part 111; U.S. Food and Drug Administration, n.d.), as shown on the label.

If you want stimulant-free, beet-free nitric-oxide support, NITRATE-IQ™ keeps it simple. Standardized spinach nitrate feeds the pathway that helps blood vessels relax, and Enovita™ grape-seed extract is the formula’s second part. There’s no caffeine, no stimulants, and no beets: no jitters, no crash, no beeturia. At the 2-scoop serving listed on the label, you get 270 mg of nitrate and 150 mg of Enovita™. If you take prescription medications, talk with your provider first. It’s designed as a daily complement to a healthy diet and exercise, and the label tells you exactly what you took.*

Taken together, that’s the case for NITRATE-IQ™: a beet-free, dose-transparent nitrate drink mix for health-conscious adults 45–70 who want to support healthy nitric-oxide levels, circulation, and blood pressure already within the normal range.*

How Does NITRATE-IQ™ Compare With Other Nitric-Oxide Options?

Compare nitric-oxide options on the criteria that matter to a label-reading, beet-averse buyer, and the differences get clear fast. The comparison below is a feature and specification comparison, not a claim of superior effectiveness.

Comparison chart of  NITRATE-IQ™ and other nitric-oxide options by taste, dose transparency, ingredients, serving flexibility and stimulants.

 

 

 

Our quality promise. NITRATE-IQ™’s spinach extract is standardized to 9% dietary nitrate, and the product is GMP manufactured, as shown on the label. That standardization is what makes the label’s exact nitrate amounts possible in the first place. The milligrams on the label are a specification, not an estimate.

Is Spinach Nitrate the Same as Beetroot Nitrate?

Yes. Spinach and beetroot deliver the same active compound: dietary nitrate, which your body converts to nitrite and then to nitric oxide. So the pathway is the same. What differs is the delivery. NITRATE-IQ™ uses a spinach extract standardized to 9% dietary nitrate with a disclosed on-label dose, and sourcing from spinach removes the earthy taste, beeturia, and beet sugar of beet products. Two spinach-meal trials in healthy adults found improvements in vascular measures and lower systolic readings (Bondonno et al., 2012; Liu et al., 2013). So spinach nitrate offers the same well-studied pathway as beetroot with cleaner delivery and a dose you can actually see, which is why it can be a practical daily nitrate source.*

Frequently Asked Questions About Beet-Free Nitric Oxide Supplements

How is NITRATE-IQ™ different from the beet products I’ve tried?

Many nitric-oxide products are beet-based, rely on a single ingredient, and don’t state their nitrate content. NITRATE-IQ™ changes all three. It’s beet-free: the nitrate comes from spinach, so there’s no beeturia, no beet sugar, and no earthy beet taste. It’s a two-part nitric-oxide formula, pairing spinach nitrate with Enovita™ grape-seed extract. And the label states the exact nitrate in each serving (135 mg per scoop, 270 mg per 2 scoops, 540 mg per 4 scoops), so you can see precisely what each serving provides.*

Will NITRATE-IQ™ turn my urine red?

No beet pigment is involved. Beeturia, where urine turns pink or red after eating beets, comes from betalain pigments in beetroot. It’s estimated to occur in about 10–14% of people and has been reported more often in people with low iron (Watts et al., 1993). NITRATE-IQ™’s nitrate comes from spinach, which carries no beet pigment, so there’s no beeturia, no beet sugar, and no earthy beet taste, while it still feeds the same nitrate-nitrite-nitric oxide pathway beets are known for. That matters because a supplement you dislike is one you stop taking.

How quickly does the body absorb dietary nitrate?

After a single dose, plasma nitrate typically peaks within about 1–2 hours and plasma nitrite at about 2–3 hours (Subramanian & Gupta, 2016; Wylie et al., 2013). In one study using a much larger dose (about 1,400 mg from beetroot juice), the blood-pressure response in healthy volunteers peaked about 2.5–3 hours after ingestion (Webb et al., 2008). Blood-pressure research on dietary nitrate has mostly used daily intake over days to a few weeks. One meta-analysis found that effects seen in resting clinic measurements were not seen in home or 24-hour monitoring (Ashor et al., 2017).*

How do I take NITRATE-IQ™?

Follow the directions on the label: 1 scoop (2 g) daily, mixed with water and taken with food. The Supplement Facts panel also lists 2-scoop (4 g) and 4-scoop (8 g) serving sizes; talk with your healthcare provider before using more than 1 scoop. One scoop (135 mg) is an entry-level daily amount, below the doses most often used in blood-pressure research. Two scoops (270 mg) falls within the range studied in dietary-nitrate research, though below the roughly 500 mg a day the newest dose-response analysis linked with a 2 mmHg change (Norouzzadeh et al., 2025). We tell you that plainly rather than implying a smaller serving does more than it does.*

For performance, plasma nitrite peaks about 2–3 hours after a dose (Wylie et al., 2013). In a large umbrella review, nitrate’s benefit for time-to-exhaustion tasks was more pronounced at about 370 mg a day or more, taken for more than 3 days. Results for other performance measures were mixed (Poon et al., 2025).*

Does NITRATE-IQ™ contain caffeine or stimulants?

No. It’s stimulant-free (no jitters, no crash), so it also fits an evening routine.

Can I see the nitrate pathway respond?

You can pair a serving with at-home saliva test strips, sometimes sold as nitric-oxide strips. These strips show salivary nitrite only; they don’t measure blood pressure or circulation.

Why is fulvic acid included if the evidence is limited?

Fulvic acid is included at a low dose as a minor ingredient. Human evidence at this dose is limited, and we make no functional claims for it.

Is NITRATE-IQ™ GMP manufactured?

Yes.  NITRATE-IQ™ is GMP manufactured, as shown on the label.

Can I take NITRATE-IQ™ if I take prescription medications?

NITRATE-IQ™ is designed to be discussed with your healthcare provider, not to replace any medication. Dietary nitrate and the naturally occurring potassium in the spinach extract can interact with several medication classes, including antihypertensives, PDE-5 inhibitors, organic nitrates, potassium-sparing diuretics, ACE inhibitors, ARBs, and blood thinners. If you take any of these, or have kidney concerns, talk with your provider before starting, and keep any prescribed regimen exactly as directed. NITRATE-IQ™ is not a substitute for medication. Consult your healthcare provider before starting any new supplement regimen, especially if you have a medical condition or take medications.

Full Ingredient, Mechanism, and Safety Documentation

Full Ingredient Breakdown

NITRATE-IQ™ is a lemon-flavored powder in a 120 g (4.23 oz) tub. The Supplement Facts panel lists three serving sizes: 1 scoop (2 g), 2 scoops (4 g) and 4 scoops (8 g). The label directions are 1 scoop daily with food and water.

Spinach Extract (Nitrate Burst™) (Spinacia oleracea, leaf): 1,500 / 3,000 / 6,000 mg per 1 / 2 / 4 scoops

Profile: a leaf extract standardized to 9% dietary nitrates and 13% naturally occurring potassium. It provides 135 / 270 / 540 mg of dietary nitrate (NO₃⁻) and 195 / 390 / 780 mg of potassium (4% / 8% / 17% DV).

Absorption and conversion profile: nitrate is absorbed, taken up by the salivary glands, reduced to nitrite by oral bacteria, then converted to nitric oxide; this conversion is enhanced in acidic, low-oxygen conditions (Lundberg et al., 2008). After a single dose, plasma nitrate typically peaks within about 1–2 hours (Subramanian & Gupta, 2016; Wylie et al., 2013).

Research context: the dietary-nitrate class has been studied in meta-analyses of randomized trials (Siervo et al., 2013; Norouzzadeh et al., 2025), with spinach-specific data from two randomized crossover meal studies (Bondonno et al., 2012; Liu et al., 2013), plus pharmacokinetic and exercise data on red spinach (amaranth), a different nitrate-rich plant (Subramanian & Gupta, 2016; Moore et al., 2017). See the nitrate intake context under Safety and Drug Interactions.

Enovita™ Grape Seed Extract (Vitis vinifera L., seed): 75 / 150 / 300 mg per 1 / 2 / 4 scoops

Profile: standardized to 95% oligomeric proanthocyanidins (OPCs); supplied by Indena.

Mechanism: in laboratory (cell-culture) research, Enovita™ increased activated eNOS and reduced endothelin-1 and sICAM-1 release (Schön et al., 2021), and grape-seed proanthocyanidins in general have shown free-radical-scavenging activity (Bagchi et al., 2000). We’re not aware of published human studies of this effect.

Research context: one randomized, placebo-controlled trial at 300 mg/day for 16 weeks, conducted with the ingredient’s supplier. The overall between-group blood-pressure difference was not statistically significant; a difference was seen in a subgroup of men (Schön et al., 2021). The 300 mg studied dose is reached at 4 scoops; the 2-scoop serving provides 150 mg.

Safety profile: grape seed extract is generally well tolerated (National Center for Complementary and Integrative Health, 2025). Dietary nitrate itself showed antiplatelet effects in a human study (Webb et al., 2008), so talk with your provider before use if you take blood thinners (anticoagulant or antiplatelet medicines).

Fulvic Acid: 30 / 60 / 120 mg per 1 / 2 / 4 scoops

Profile: fulvic acid is included at a low dose as a minor ingredient. Human evidence at this dose is limited, and we make no functional claims for it.

Other ingredients: citric acid, organic lemon flavor (natural flavor and organic acacia) and organic stevia. Vegan, gluten-free, soy-free and GMO-free, as shown on the label. No beet sugar.

Detailed Mechanism of Action

NITRATE-IQ™ is a two-part nitric-oxide formula. On timing, plasma nitrate rises within about 1–2 hours of a dose and plasma nitrite at about 2–3 hours (Wylie et al., 2013). On location, the conversion of nitrite to nitric oxide is enhanced in acidic, low-oxygen conditions (Lundberg et al., 2008), unlike the enzyme-based eNOS pathway, which requires oxygen. The second part, Enovita™ grape-seed extract, has shown eNOS and antioxidant activity in laboratory research only (Schön et al., 2021; Bagchi et al., 2000). The design goal is simple: a measured nitrate source, plus a grape-seed extract with a published human trial at a stated dose.

 

 

Safety and Drug Interactions

Dietary nitrate is a well-characterized dietary ingredient. For context, regulators have set an acceptable daily intake (ADI) for nitrate from all sources of 3.7 mg per kg of body weight per day, about 259 mg for a 70 kg adult. The 2-scoop serving is at about that level, and the 4-scoop serving is roughly double it, before counting nitrate from vegetables in your diet. In its 2017 review, EFSA’s expert panel concluded that the methemoglobin levels expected from this conversion would not be clinically significant (EFSA Panel on Food Additives and Nutrient Sources added to Food, 2017). Talk with your provider before using more than the labeled 1 scoop, especially if you have kidney concerns.

Because this formula supplies nitrate and potassium, it warrants care alongside certain medications. Talk with your healthcare provider before use if you take antihypertensives, PDE-5 inhibitors, organic nitrates, potassium-sparing diuretics, ACE inhibitors, ARBs, or blood thinners, or if you have kidney concerns. Antiseptic mouthwash can reduce the oral bacteria this pathway depends on (Kapil et al., 2013), so consider avoiding it for a few hours around your dose. Pregnant or breastfeeding women should consult their healthcare provider before using this or any dietary supplement. This product is formulated for adults ages 18 and over.  NITRATE-IQ™ is not a substitute for any medication, and nothing here is medical advice; your provider is the right source for guidance on your specific situation.

Is NITRATE-IQ™ a Good Fit for You?

You understand why beet products left you dosing blind, and how a two-part nitric-oxide formula with a printed dose is different. That’s a very different starting point from the last tub you tried.

NITRATE-IQ™ is the beet-free, dose-transparent nitrate drink mix for health-conscious adults 45–70 who want to support healthy nitric-oxide levels, circulation, and blood pressure already within the normal range.*

Its dietary nitrate has been studied in ingredient-level research, its Enovita™ grape-seed extract has a published randomized trial at a stated dose, and the whole product is built for label-literate adults who want transparent, standardized nitrate dosing instead of another proprietary blend.

NITRATE-IQ™ may be a good fit when:

✓ an adult wants to support healthy blood pressure already within the normal range without starting from a beet product*

✓ a previous beet supplement was abandoned over earthy taste, beeturia, or beet sugar

✓ a label-literate buyer wants a disclosed, standardized nitrate dose to build a repeatable daily routine

✓ stimulant-free daily support is a priority

✓ someone wants a single product with 1-, 2- and 4-scoop serving sizes listed on the label

NITRATE-IQ™ may not be necessary when:

○ an inexpensive food-based nitrate approach already fits comfortably into the diet

○ someone has no objection to beets and a basic beet product is well tolerated

If you’re under a physician’s care for blood pressure or heart health, talk with your provider before adding any supplement.

Start your first serving with confidence.
