HelloPharmacist Scorecard of N.O.7 by Steel Supplements

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 4 active ingredients.
  • “SurePump” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

N.O.7 contains four active ingredients. The main one is pomegranate (Punica granatum), a fruit extract with a long history in traditional and modern wellness.

The product also contains (-) Epicatechin, N.O.7, and SurePump, though we don't have detailed monographs on those three. The capsule itself holds inactive ingredients—gelatin, magnesium stearate (a flow agent), and silicon dioxide (an anti-caking powder)—that help it hold together and go down smoothly.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Nitric oxide booster.
  • We looked for evidence on: Atherosclerosis, Coronary heart disease (CHD), Erectile dysfunction (ED), Hypertension, Stroke, Athletic performance — and 4 related terms.
  • The strongest evidence on file: Pomegranate is rated "Possibly Effective" for Hypertension (Natural Medicines).
  • Also on file: Pomegranate is rated "Possibly Ineffective" for Hyperlipidemia.
  • Also on file: Pomegranate is rated "Insufficient Reliable Evidence To Rate" for Atherosclerosis, Athletic performance, Coronary heart disease (CHD), Erectile dysfunction (ED), and more.

For pomegranate, the evidence is mixed depending on what you're taking it for. It's rated possibly effective for high blood pressure—some research suggests it can lower it modestly.

However, it's rated possibly ineffective for high cholesterol and blood sugar control, meaning current research doesn't support those uses. For fatty liver disease, there isn't enough reliable evidence yet to know whether it helps.

The effectiveness of the other three active ingredients in this product isn't established in the data we hold.

The evidence, ingredient by ingredient Pomegranate

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pomegranate fruit and juice are generally well tolerated as food—most people use them without trouble. The most common mild side effects reported in clinical studies were diarrhea and flatulence; in one study, 10% of people taking a high-dose extract experienced diarrhea, and a small number had nausea, stomach pain, constipation, or vomiting.

Because this product contains concentrated pomegranate extract rather than whole fruit, the data suggest using caution, especially at high doses. Pomegranate root, stem, and peel should not be used in large amounts.

In pregnancy and lactation, pomegranate is rated possibly safe, though you should discuss supplement use with your doctor or pharmacist for personalized advice specific to your situation.

Side effects, ingredient by ingredient Pomegranate

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Pomegranate.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 923 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking N.O.7, flag these medication types with your doctor or pharmacist: blood thinners (anticoagulants), especially warfarin; blood pressure medications (antihypertensives); ACE inhibitors; drugs your liver breaks down via CYP2D6, including some antidepressants and heart drugs; statins, particularly rosuvastatin; seizure medications like carbamazepine; and any other drugs processed by your liver. We could not check the other three active ingredients for interactions, so mention this product to your healthcare provider by name.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take any blood pressure medication, blood thinner, ACE inhibitor, statin, or drug that your liver processes via CYP2D6, you need to check with your doctor or pharmacist before starting this product—pomegranate can meaningfully interact with those. If you have a history of digestive upset, start with a lower dose and see how you feel.

Talk it over with your own healthcare provider about whether N.O.7 makes sense for what you're trying to achieve.

For each ingredient in N.O.7 with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Punica granatum9 drug types · 922 drugs

Ace Inhibitors (Aceis)

Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.
Pomegranate juice is thought to have ACE inhibitor-like effects.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.
In vitro, pomegranate juice inhibits CYP2D6. However, the clinical significance of this potential interaction in humans is not known.

Likelihood Possible Evidence D
Rosuvastatin (Crestor)

Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.
In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.
In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase. In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption. The mechanism of this potential interaction is unclear.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4. However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.
Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity. However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.
Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice. In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times; however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration. Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans.

Likelihood Unlikely Evidence B
Tolbutamide (Orinase)

Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9. Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans. This interaction does not appear to be clinically significant in humans.

N.O.7 by Steel Supplements: Common Questions

Does N.O.7 by Steel Supplements interact with any medications?
Yes. Based on its ingredients, N.O.7 has a known interaction with 922 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
N.O.7 contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does pomegranate actually lower blood pressure?
Yes—research shows pomegranate juice can modestly lower blood pressure. That's why it's rated possibly effective for high blood pressure. But if you're already on a blood pressure drug, that's also why you need to check with your doctor first; the combination could drop your pressure too far.
Can I take this if I'm on a statin like atorvastatin or rosuvastatin?
That depends on which statin. There's a documented case of muscle breakdown (a serious condition) in someone taking rosuvastatin with pomegranate juice, so rosuvastatin specifically needs a conversation with your pharmacist. Atorvastatin and other statins may have lower risk, but check first—don't start this on your own.
What are the side effects I might notice?
Most common are mild digestive ones—diarrhea and gas. In studies using higher doses of pomegranate extract, some people also reported nausea, stomach pain, constipation, or vomiting, though that was a smaller number. Start with one capsule and see how your stomach feels.
Is it safe to take while pregnant or breastfeeding?
Pomegranate is rated possibly safe for pregnancy and lactation, but that's not a green light to take a supplement on your own. Talk with your doctor or midwife first—they know your full situation and can advise whether this product makes sense for you right now.
Will this help my cholesterol or blood sugar?
Research suggests pomegranate is likely ineffective for both high cholesterol and blood sugar control, so it's not the right tool for those goals. Stick with the medications and lifestyle changes your doctor recommends instead.
Can I stop taking warfarin if I use pomegranate juice instead?
No—absolutely not. Warfarin is a prescription medication that requires careful monitoring and a doctor's supervision. Pomegranate juice shouldn't replace it, and starting or stopping either one without your doctor's approval risks serious bleeding complications.
