Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

CN3 contains 2 active ingredients: vitamin C and creatine nitrate. Vitamin C is an antioxidant and essential nutrient that supports immune function and tissue repair.

Creatine nitrate is a compound that combines creatine (used by muscles for energy) with nitrate, which may support muscle strength and athletic performance. The product also contains inactive ingredients like citric acid, sucralose, and food coloring for flavor and texture.

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 and muscle pump amplifier.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Muscle strength, Muscle breakdown, muscular endurance, power output — and 1 related terms.
  • The strongest evidence on file: Creatine is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Creatine is rated "Possibly Effective" for Muscle strength.
  • Also on file: Creatine is rated "Insufficient Reliable Evidence To Rate" for Muscle breakdown.

Vitamin C is effective for treating vitamin C deficiency and is possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and reducing respiratory infections from heavy exercise. Creatine nitrate is possibly effective for building muscle strength, improving athletic performance, and treating sarcopenia (age-related muscle loss), and possibly effective for cerebral creatine deficiency syndromes.

However, it is possibly ineffective for Huntington disease and osteopenia.

The evidence, ingredient by ingredient Vitamin C 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.

Vitamin C is generally well tolerated at normal doses, but very high doses (above 2 grams daily) can cause abdominal cramps, heartburn, diarrhea, nausea, and kidney stones in people prone to them. Creatine is generally well tolerated in healthy adults, though common side effects include dehydration, diarrhea, muscle cramps, and water retention.

People with kidney problems should be cautious with creatine. For pregnancy, normal amounts of vitamin C from food and prenatal vitamins are fine, but avoid high-dose vitamin C supplements unless your doctor advises it; safety data for creatine in pregnancy has not been established, so it should be avoided.

If you're breastfeeding, there is not enough safety information for creatine, so avoid it — talk with your pharmacist about vitamin C while nursing.

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.

CN3 may help with muscle performance and athletic gains, and provides vitamin C for general health. However, if you take estrogens (like birth control), warfarin, levothyroxine, chemotherapy, or HIV medications, you need to check with your doctor or pharmacist before starting — vitamin C can affect how these drugs work.

Anyone with kidney problems should also discuss this with their healthcare provider before using it.

Vitamin C13 drug types · 207 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Aluminum

Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.

Likelihood Probable Evidence B
Antitumor Antibiotics

Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Estrogens

Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.

Likelihood Probable Evidence B
Fluphenazine (Prolixin)

Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.

Likelihood Possible Evidence D
Indinavir (Crixivan)

Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.

Likelihood Probable Evidence B
Warfarin (Coumadin)

High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.

Likelihood Probable Evidence B
Aspirin

Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction is not clinically significant.

Likelihood Possible Evidence B
Choline Magnesium Trisalicylate (Trilisate)

Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Niacin

Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Salsalate (Disalcid)

Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

CN3 2 In 1 Super Compound: Creatine Nitrate Fruit Punch by Cellucor: Common Questions

Does CN3 2 In 1 Super Compound: Creatine Nitrate Fruit Punch by Cellucor interact with any medications?
Yes. Based on its ingredients, CN3 2 In 1 Super Compound: Creatine Nitrate Fruit Punch has a known interaction with 207 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CN3 2 In 1 Super Compound: Creatine Nitrate Fruit Punch contains 2 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 this have any fillers or just the active ingredients?
It contains two active ingredients — vitamin C and creatine nitrate — plus inactive ingredients like citric acid, sucralose, coloring, and anticaking agents for the powder form. These are standard excipients used to make the product shelf-stable and flavored.
Will this help me build muscle and get stronger?
Creatine nitrate is possibly effective for muscle strength and athletic performance. Vitamin C supports general health and tissue repair but isn't specifically studied for muscle building. Results depend on your training, diet, and individual response.
Is it safe if I'm taking a diuretic (water pill) or have kidney disease?
Creatine can cause water retention and dehydration, and people with kidney problems should be cautious with it. Talk with your doctor or pharmacist before using this product if you have kidney disease or take diuretics — they can advise if it's right for you.
What are the most common side effects?
From vitamin C: abdominal cramps, heartburn, diarrhea, and nausea — mostly at very high doses. From creatine: dehydration, diarrhea, muscle cramps, and water retention. These tend to be mild and often decrease with continued use.
Can I take this if I'm pregnant or breastfeeding?
Normal vitamin C from food and prenatal vitamins is fine in pregnancy, but high-dose supplements should only be taken if your doctor advises it. Creatine safety in pregnancy has not been established, so it should be avoided. If breastfeeding, avoid creatine — ask your pharmacist about vitamin C while nursing.
