Beetroot has become one of the best-known natural sources of dietary nitrate. Beet juice, beetroot powders, and concentrated beet shots are now widely used by athletes and people interested in supporting nitric oxide production.

But beetroot is not the only plant that naturally contains nitrate.

Red spinach is a beetroot alternative that can deliver a measured amount of naturally occurring nitrate in a relatively small serving. That raises an important question:

Is red spinach better than beetroot for nitric oxide?

The most accurate answer is that both can be useful—but they are not interchangeable.

Beetroot offers a familiar food-based source of nitrate, along with betalains and other naturally occurring plant compounds. A standardized red spinach extract may offer greater concentration, dose precision, and convenience when the goal is to consume a specific measured amount of dietary nitrate.

The most important comparison is not simply which plant sounds more appealing. It is:

·      How much nitrate the product provides

·      Whether that amount is measured and disclosed

·      Whether it remains consistent from serving to serving

·      How much powder or liquid must be consumed

·      What else the product contains

·      Whether the format is practical enough to use consistently

 

Red Spinach vs. Beetroot at a Glance

The most important distinction is not simply red spinach versus beetroot. It is whether the finished product provides a meaningful and verified nitrate dose.

 

Why Dietary Nitrate Matters

Nitric oxide is a signaling molecule involved in normal blood-vessel function, circulation, muscle physiology, and many other processes throughout the body.

The body can produce nitric oxide through more than one pathway. One begins with amino acids such as L-arginine. Another begins with nitrate obtained from food.

After nitrate is consumed, much of it is absorbed into the bloodstream. Some is then concentrated in the salivary glands and returned to the mouth through saliva. Nitrate-reducing bacteria on the tongue help convert nitrate into nitrite. After the nitrite is swallowed, part of it can be converted into nitric oxide and other biologically active nitrogen compounds.

This is commonly described as the:

Nitrate → Nitrite → Nitric Oxide pathway

The involvement of oral bacteria is one reason strong antibacterial mouthwash may interfere with nitrate metabolism. Human studies have found that antiseptic mouthwash can reduce the oral conversion of nitrate to nitrite.

This pathway helps explain why nitrate-rich vegetables and standardized dietary nitrate supplements have received so much attention in exercise and cardiovascular research.

It also explains why the nitrate content of a product matters. A package can prominently feature beetroot or another nitrate-rich plant without necessarily providing a meaningful or consistent amount of nitrate.

What Is Red Spinach?

Red spinach is a common name used for leafy plants within the Amaranthus genus. It is different from conventional green spinach, or Spinacia oleracea, and it is not beetroot.

Like other leafy vegetables, red spinach can naturally accumulate nitrate. Through extraction and concentration, it can be made into an ingredient that supplies a measured quantity of naturally occurring nitrate.

A fresh plant is an agricultural food whose nitrate level can naturally vary. A standardized extract is produced to meet a defined specification.

Human research involving nitrate-rich red spinach extracts has examined nitrate and nitrite availability, vascular responses, resistance exercise, repeated sprint performance, perceived exertion, and other measures related to exercise physiology.

The scientific literature on red spinach remains much smaller than the research record for beetroot. Its most practical advantage is therefore not that beetroot “does not work.” It is that red spinach can be made into a concentrated and standardized ingredient that delivers a known nitrate amount in a relatively small serving.

What Is Beetroot?

Beetroot, commonly called beet in the United States, is the root portion of Beta vulgaris.

Beetroot may be consumed as:

·      Whole cooked or raw beets

·      Beet juice

·      Concentrated beet shots

·      Beet crystals

·      Dehydrated beetroot powder

·      Capsules, gummies, or chews

·      Sports-nutrition products

Beetroot naturally contains nitrate, colorful betalain pigments, and other plant compounds. Beetroot juice is one of the most extensively studied food-based sources of dietary nitrate.

This larger research record is a genuine advantage for beetroot.

However, findings from studies using nitrate-rich beetroot juice cannot automatically be applied to every beet powder, capsule, gummy, or food product. A study using a product that supplied a known nitrate dose does not prove that an unstandardized beet powder provides the same amount.

Red Spinach Nitrate vs. Beetroot Nitrate

Nitrate is the same ion whether it originates in red spinach, beetroot, arugula, lettuce, or another vegetable.

The body does not produce a separate form of “red spinach nitric oxide” or “beetroot nitric oxide.”

The meaningful differences are:

1.        The quantity of nitrate supplied

2.        Whether that quantity has been measured

3.        Whether the concentration is standardized

4.        Whether the serving remains consistent

5.        The amount of powder or liquid required

6.        The other nutrients and compounds in the product

7.        The practicality of taking it regularly

This is where a standardized red spinach extract can have a meaningful advantage.

A product standardized to a particular nitrate concentration can disclose how much naturally occurring nitrate is present in each serving. By comparison, many conventional beetroot powders disclose only the total weight of the powder.

For example:

·      “5 grams of beetroot powder” describes the weight of the powder.

·      “400 milligrams of naturally occurring nitrate” describes the amount of nitrate being supplied.

Those statements do not communicate the same information.

A large serving of an unstandardized powder could supply less nitrate than a small serving of a concentrated red spinach extract. Without nitrate testing or disclosure, the consumer cannot make a reliable comparison.

Which Has More Nitrate: Red Spinach or Beetroot?

It is tempting to answer this with a simple ranking, but fresh plants are not standardized ingredients.

The nitrate concentration of vegetables can be influenced by:

·      Species and variety

·      Soil conditions

·      Fertilization

·      Light exposure

·      Growing season

·      Growing region

·      Harvest timing

·      Storage

·      Processing

·      Extraction and concentration methods

Leafy greens frequently rank among the most nitrate-rich categories of vegetables, but there can be substantial variation among plants and samples.

For that reason, it would be misleading to claim that every red spinach leaf contains a fixed multiple of the nitrate in every beetroot.

The more defensible comparison is between tested ingredients and finished products.

For example, an extract standardized to 9% nitrate contains approximately 90 milligrams of nitrate per gram:

At that concentration, approximately 4.4 grams provides about 400 milligrams of naturally occurring nitrate.

A beetroot product could also provide approximately 400 milligrams of nitrate. However, depending on the product’s nitrate concentration, reaching that amount may require a larger or more expensive serving. Larger servings of beetroot juice or concentrate may also cause digestive discomfort in some people.

Consumers should therefore look for products that measure and disclose the nitrate amount rather than estimating it from the amount of beetroot powder or juice. The advantage belongs to the product that provides a meaningful, measured, and repeatable dose—not automatically to whichever vegetable appears on the front of the package.

Can Beetroot Powder Be Concentrated Like Red Spinach?

Beetroot can be dried and concentrated into powders and extracts. The challenge is producing a small, economical serving of beetroot powder that delivers approximately 400 milligrams of naturally occurring nitrate.

Conventional beetroot powders generally contain much less nitrate per gram than red spinach extract standardized to 9% nitrate. Because nitrate concentrations can also vary among beetroot ingredients, reaching a 400-milligram nitrate serving may require a substantially larger amount of beetroot powder.

By comparison, approximately 4.4 grams of red spinach extract standardized to 9% nitrate provides about 400 milligrams of naturally occurring nitrate.

Producing a beetroot powder with a comparable nitrate concentration may require additional extraction and processing, which can substantially increase ingredient cost. This may help explain why concentrated, transparently formulated beetroot powders that clearly disclose approximately 400 milligrams of naturally occurring nitrate per serving are not commonly available to consumers.

A manufacturer could also add nitrate from another botanical or mineral source, but in that case the nitrate would not come exclusively from beetroot. Consumers should therefore confirm both the amount and the stated source of nitrate rather than assuming that all nitrate in a beet-branded product was naturally supplied by the beetroot powder itself.

These differences can affect:

• Serving size

• Ingredient cost

• Flavor intensity

• Sugar and carbohydrate content

• Space available for other ingredients

• The number of chewables or tablets required

• Consumer convenience

Consumers should look beyond terms such as “concentrated beetroot powder” and determine whether the product discloses:

• Milligrams of nitrate per serving

• The source of the nitrate

• The total amount of powder required

• Whether the nitrate concentration is standardized and verified

Beetroot powder can supply dietary nitrate. The practical advantage of standardized red spinach extract is that it can provide approximately 400 milligrams of naturally occurring nitrate in a relatively small dry serving without requiring nitrate from another source.

Beetroot Powder vs. Standardized Red Spinach Extract

Beetroot powder is typically made by dehydrating beetroot or beetroot juice. It can be a convenient way to include beet compounds in a powdered formulation, but dehydration alone does not guarantee a particular nitrate concentration.

Many beetroot powders list information such as:

·      5 grams of beetroot powder

·      10,000 milligrams of beet equivalent

·      A 10:1 extract ratio

·      The equivalent of several whole beets

These descriptions may help explain how the powder was produced or how much plant material it represents. They do not necessarily state how much nitrate is in the finished serving.

A standardized red spinach extract can provide a more precise comparison because the nitrate concentration is controlled to meet a specification.This does not mean all beetroot powders are ineffective. Some specialized beet products are standardized or clearly disclose their nitrate content. Those products should be evaluated differently from conventional powders that disclose only ingredient weight.

Red Spinach vs. Beet Juice

Beet juice is the format most closely associated with dietary-nitrate research.

It may be a good option for people who:

·      Enjoy beetroot

·      Prefer a liquid

·      Want beetroot’s broader whole-food compounds

·      Use a product that discloses nitrate content

·      Do not mind the taste, volume, or refrigeration requirements

·      Do not mind plastic bottles

A concentrated beet shot is also different from ordinary beet juice. A small sports-nutrition shot may be formulated to provide a known nitrate amount, while a larger glass of ordinary beet juice may not be standardized.

A concentrated red spinach extract can offer practical differences:

·      No liquid volume

·      Easier portability

·      A mild flavor profile

·      Lower naturally occurring sugar in many formulations

·      A measured nitrate amount

·      No refrigeration for a shelf-stable powder

The proper comparison is therefore not simply powder versus juice. It is measured nitrate, total serving size, other ingredients, and personal preference.

Serving Size and Convenience

The best supplement is not useful if a person dislikes it enough to stop taking it.

A concentrated red spinach extract can deliver nitrate in a relatively small serving because the ingredient has been concentrated and standardized.

By comparison:

·      A conventional beet powder may require several grams.

·      A beet drink may require a larger liquid serving.

·      Concentrated beet juice may retain a strong beet flavor.

·      Beet juice adds weight and volume for travel.

·      Beet juice may cause digestive issues.

For athletes, travelers, and people using nitrate regularly, serving size can become more than a minor convenience. It can determine whether the product fits consistently into daily life.

Taste: Does Red Spinach Taste Like Beets?

Beetroot has a distinctive earthy flavor. Some people enjoy it, while others find it difficult to consume regularly.

Red spinach does not naturally have the same pronounced beet flavor. A concentrated red spinach extract generally has a milder plant taste, although the experience will depend on:

·      The amount used

·      Flavoring

·      Sweeteners

·      Other ingredients

·      Whether it is consumed in water, food, tablets, or another format

It would be too broad to say that every red spinach product tastes better than every beet product.

However, for people who avoid beetroot specifically because of its earthy flavor, red spinach may provide an easier beet alternative.

Sugar and Calories

Whole beetroot is a nutritious vegetable, and its naturally occurring sugar should not automatically be treated as undesirable.

The practical issue is that different nitrate sources can deliver different amounts of sugar, carbohydrates, and calories.

Beet juice may contain more naturally occurring sugar and calories than a concentrated red spinach extract. Beetroot powders and flavored beet supplements also vary, particularly when they include:

·      Added sugar

·      Maltodextrin

·      Fruit powders

·      Flavor systems

·      Gummy ingredients

·      Other carbohydrate carriers

A concentrated red spinach extract can provide nitrate with relatively little naturally occurring sugar. The finished product still needs to be evaluated because flavors, carriers, and other ingredients can change its nutrition profile.

Consumers should compare the complete Supplement Facts or Nutrition Facts panels rather than assuming every beetroot or red spinach product has the same composition.

Oxalates: Red Spinach vs. Beetroot

Oxalate is a naturally occurring compound found in many plant foods. Beetroot is commonly identified as an oxalate-containing food, although measured levels can vary among samples and analytical methods.

Oxalate intake is not a concern for everyone. It may receive greater attention from people who have been advised by a qualified healthcare professional to limit oxalates.

This comparison requires care because raw plants within the Amaranthus genus may also contain oxalates. It would therefore be inappropriate to assume that every red spinach plant or untreated red spinach ingredient is inherently oxalate-free.

The more relevant question is whether a particular red spinach extract has been processed and tested to confirm that oxalates are absent or below the laboratory’s reporting threshold.

Red Spinach Company states that the red spinach extract used in its products has been tested and confirmed as oxalate-free.

Consumers concerned about oxalates should look for product-specific testing rather than relying solely on the name of the plant.

Red Spinach, Beetroot, and Exercise Performance

Beetroot currently has the larger exercise-research record.

Reviews and meta-analyses suggest that dietary nitrate may improve certain measures of exercise capacity or performance, but results vary. Effects may depend on:

·      Nitrate dose

·      Timing

·      Duration of supplementation

·      Type and duration of exercise

·      Training status

·      Age

·      Diet

·      Oral microbiome

·      Individual responsiveness

Some analyses have found positive effects in selected endurance-capacity tests and exercise sessions, while others have reported mixed or limited results.

Research often evaluates nitrate intakes of several hundred milligrams. This does not establish one universal dose for every person or activity, but it demonstrates why knowing the nitrate content of a product is important.

Red spinach has a smaller human research record. Studies have examined nitrate-rich red spinach extract in resistance-trained men and competitive female athletes, including its effects on blood nitrate and nitrite concentrations, perceived exertion, barbell velocity, repeated sprint performance, and fatigue-related outcomes.

The results have not shown an improvement in every outcome. That nuance is important. The research supports red spinach as a clinically studied nitrate source, but it should not be presented as a guaranteed performance enhancer.

For a sports formulation, the clearest practical advantage of standardized red spinach is that an athlete can know how much nitrate is being consumed without relying on assumptions about an unstandardized plant powder.

Circulation and Healthy Aging

Normal aging can be accompanied by changes in vascular function and nitric oxide biology. Dietary nitrate has therefore been studied not only in athletes but also in the context of normal cardiovascular and age-related physiology.

Research involving nitrate-rich foods suggests that the nitrate–nitrite–nitric oxide pathway can provide an alternative route for nitric oxide production. However, outcomes differ among populations, and dietary nitrate supplements should not be presented as treatments for hypertension, vascular disease, or another medical condition.

The appropriate consumer positioning is support for normal:

·      Nitric oxide production

·      Blood-vessel function

·      Circulation

·      Exercise physiology

·      Healthy aging

People taking medication, managing low blood pressure, or receiving treatment for cardiovascular or kidney conditions should discuss nitrate supplementation with an appropriate healthcare professional.

Who Might Prefer Beetroot?

Beetroot may be the better choice for someone who:

·      Enjoys the flavor of beets

·      Has little or no concern about oxalates

·      Wants betalains and other beetroot compounds

·      Prefers whole foods or juice

·      Does not mind the serving size or liquid format

·      Is not seeking a beet-free option

Beetroot remains a legitimate and well-researched source of dietary nitrate.

Who Might Prefer Red Spinach?

Standardized red spinach may be the better practical choice for someone who:

·      Wants a measured amount of nitrate

·      Prefers a smaller serving

·      Dislikes beet flavor

·      Wants an alternative to beetroot

·      Wants to compare nitrate milligrams rather than powder weight

·      Prefers a portable, shelf-stable powder or tablet

·      Wants consistency from serving to serving

·      Is looking for a plant-based nitrate supplement without relying on beetroot

Red Spinach Company currently offers two single-ingredient red spinach extract options: RS400 for a higher targeted nitrate serving and VitaSpinach for daily use.

Is Red Spinach Better Than Beetroot?

Neither plant is automatically better in every respect.

Beetroot offers:

·      A larger research history

·      Familiarity

·      Betalains

·      Whole-food and juice options

·      Wide availability

Standardized red spinach offers:

·      A concentrated nitrate source

·      A measured and disclosed dose

·      A relatively small serving

·      A milder taste alternative

·      Consistency from serving to serving

·      A practical beetroot alternative for nitric oxide

When the primary goal is obtaining a particular amount of nitrate, a standardized extract has an advantage over an unstandardized powder—whether that powder is made from beetroot, red spinach, or another vegetable.

The best comparison is:

How much nitrate does the finished product provide, and has that amount been verified from the plant source?

What to Look for in a Dietary Nitrate Supplement

Before choosing a dietary nitrate supplement, consider the following:

1. Nitrate milligrams per serving

Look for the amount of naturally occurring nitrate, not just the number of grams of plant powder. If that information is not provided, ask the seller. If they don't know or won't disclose it, you may want to consider another source. You deserve to know exactly how much naturally occurring nitrate you're getting.

2. Standardization

A standardized ingredient is manufactured to meet a defined concentration.

3. Serving size

Confirm how much powder, liquid, or how many tablets are required to obtain the stated nitrate amount.

4. Finished-product testing

Ingredient specifications are important, but testing the finished product provides additional confirmation after manufacturing.

5. Complete ingredient list

Check for added sugar, flavors, or stimulants.

6. Botanical identity

The product should clearly identify the plant being used rather than relying only on a general marketing name.

7. Intended use

A product designed for exercise may provide a different nitrate amount than one intended for everyday dietary support.

8. Realistic claims

Be cautious with products promising immediate or guaranteed effects. Individual responses to dietary nitrate vary.

Summary

Red spinach and beetroot can both provide naturally occurring dietary nitrate that participates in the nitrate–nitrite–nitric oxide pathway.

Standardized red spinach offers a different set of advantages: concentration, nitrate transparency, a smaller serving, a milder taste, and consistency.

For consumers focused specifically on nitric oxide support, the most useful number on the label is not necessarily the number of grams of beetroot or red spinach.

It is the number of milligrams of naturally occurring nitrate per serving.

That is what makes it possible to compare products fairly.

Frequently Asked Questions

Is red spinach the same as beetroot?

No. Red spinach is a leafy plant within the Amaranthus genus, while beetroot is the root of Beta vulgaris. Both can contain naturally occurring nitrate, but they are botanically different plants with different nitrate concentrations.

Is red spinach better than beetroot for nitric oxide?

It depends on the product and the consumer’s priorities. Beetroot has a larger research record, while standardized red spinach can provide a measured nitrate amount in a relatively small serving. For nitric oxide purposes, nitrate quantity and standardization may matter more than the plant name alone.

Which contains more nitrate, red spinach or beetroot?

Nitrate content varies among plants and growing conditions. A concentrated red spinach extract may contain as much as 5x to 50x more nitrate per gram than conventional beetroot powder or juice, but the most reliable comparison is between finished products that disclose tested nitrate amounts.

Does beetroot powder provide enough nitrate?

Some beetroot powders may provide a meaningful amount, but many disclose only grams of beet powder rather than milligrams of nitrate. Without testing or nitrate disclosure, it is difficult to know how much nitrate the serving supplies.

What is a good alternative to beetroot powder?

A standardized red spinach extract is one plant-based alternative. It can provide naturally occurring nitrate in a concentrated serving, without oxalates, and without the distinctive taste of beetroot.

Does red spinach taste like beets?

No. Red spinach does not have the same pronounced earthy beet flavor.

Does red spinach contain oxalates?

Raw plants within the Amaranthus genus may contain oxalates. Whether a particular extract is oxalate-free should be established through product-specific testing. The red spinach extract used in Red Spinach Company products has been tested and confirmed as oxalate-free.
