HelloPharmacist Scorecard of Con-Cret + Nitric Oxide with HydroNOX Blood Orange Berry by CON-CRET

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.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This powder has three active ingredients. Beet powder is your source of natural nitrates and betanin, a pigment that may support exercise performance and muscle soreness.

Creatine hydrochloride is a form of creatine, which helps muscles produce energy during intense activity and may support strength and athletic performance. Hydronox is the third ingredient, though we don't have detailed information on file for it.

The product also contains inactive ingredients — natural flavors, citric acid for tartness, and rebaudioside A, a sweetener.

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: Strength, endurance, and muscle pump.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Exercise-induced muscle soreness, Muscle strength, Physical performance, Muscle breakdown — and 3 related terms.
  • The strongest evidence on file: Beet is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Beet is rated "Possibly Effective" for Exercise-induced muscle soreness.
  • Also on file: Creatine is rated "Possibly Effective" for Athletic performance, Muscle strength.

Beet powder in this product is possibly effective for athletic performance and exercise-induced muscle soreness based on available evidence. It's rated possibly ineffective for COPD, and we don't have enough reliable evidence to rate it for dyslipidemia or cognitive function.

Creatine is possibly effective for muscle strength and athletic performance, and possibly effective for sarcopenia and cerebral creatine deficiency syndromes. It's rated possibly ineffective for Huntington disease and osteopenia.

We don't have established evidence for Hydronox.

The evidence, ingredient by ingredient Beet Creatine

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Beet is widely eaten as food and generally well tolerated, though concentrated supplements like this powder lack long-term safety data — use caution. The most common side effect is red or dark stools, which is harmless.

Rare but serious effects from large amounts include low blood calcium and kidney damage. Creatine is generally well tolerated in healthy adults but requires caution if you have kidney problems.

Common side effects are dehydration, diarrhea, gastrointestinal upset, muscle cramps, and water retention. Rare serious effects include kidney inflammation, muscle breakdown, and blood clots.

Creatine is not recommended during pregnancy or while nursing — safety hasn't been established. There's no pregnancy or breastfeeding data on file for beet or Hydronox.

Side effects, ingredient by ingredient Beet Creatine

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 2 matched ingredients can interact with medications — Beet.
  • The most serious interaction on file is rated Moderate.
  • For scale: 862 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.

Check your exact medications if you take CYP3A4 substrates (Moderate interaction with beet); these include statins, many blood pressure drugs, some immunosuppressants, and certain antihistamines. Also double-check if you take blood pressure-lowering medications, since beet may lower pressure further (Minor).

If you take CYP1A2 substrates like theophylline or certain antidepressants, mention this product to your pharmacist (Minor).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're an athlete looking to support performance and muscle recovery, beet and creatine have evidence behind them. Anyone taking medications metabolized by CYP3A4 — a common group that includes many statins, blood pressure drugs, and immunosuppressants — needs to check with their pharmacist first.

People with kidney disease, or anyone pregnant or nursing, should talk to their doctor before starting creatine.

Beet, Powder3 drug types · 861 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D
Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

Likelihood Possible Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Con-Cret + Nitric Oxide with HydroNOX Blood Orange Berry by CON-CRET: Common Questions

Does Con-Cret + Nitric Oxide with HydroNOX Blood Orange Berry by CON-CRET interact with any medications?
Yes. Based on its ingredients, Con-Cret + Nitric Oxide with HydroNOX Blood Orange Berry has a known interaction with 861 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Con-Cret + Nitric Oxide with HydroNOX Blood Orange Berry contains 3 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.
Will this give me red pee or poop?
Red or dark-colored stools and urine are the most common effects of beet supplements and are completely harmless — they're just the beet pigment passing through. It's not a sign something's wrong.
Can I take this if I'm pregnant or breastfeeding?
Creatine in this product should be avoided during pregnancy and while nursing because safety hasn't been established. We don't have safety data on file for beet or Hydronox in pregnancy or lactation either. Talk with your doctor or midwife before using this product.
Is creatine safe for my kidneys?
Creatine is generally well tolerated in healthy adults with normal kidney function. If you have any kidney disease or reduced kidney function, use caution and check with your doctor first — the data advises being careful in that situation.
What does creatine actually do?
Creatine helps your muscles produce the energy they need during intense exercise. The evidence shows it's possibly effective for muscle strength and athletic performance, and may help with sarcopenia (age-related muscle loss).
Can I get the same benefit from beet juice instead of this powder?
Beet juice and beet powder contain the same active compounds. We have more safety data on beet as a whole food than on concentrated supplements like this powder, so if you're concerned about long-term safety, whole beets or juice might be worth asking your pharmacist about.
