What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 5 of its 9 active ingredients.
  • “Metabolic Activator Blend (Combination)” is a proprietary blend — the label gives one combined amount (247 mg) without saying how much of each component you get.
  • “T7 Extreme Blend (Combination)” is a proprietary blend — the label gives one combined amount (242 mg) without saying how much of each component you get.

This product contains 9 ingredients, of which the active ones are niacinamide (a form of vitamin B3), cayenne pepper extract, white willow bark extract, 3-iodotyrosine, a metabolic activator blend, a T7 extreme blend (a proprietary combination), zinc arginate chelate, wakame extract, griffonia seed extract, methylselenocysteine, and 3,5 diiodotyrosine. The inactive ingredients are rice flour, magnesium stearate, and a capsule shell.

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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: stimulant free fat burner.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Evidence on the active ingredients here is mixed. Niacinamide is well-studied for pellagra (a vitamin deficiency disease) and has some support for acne, arthritis, and diabetes, though the evidence for those last three is still emerging.

Cayenne has good evidence for nerve pain conditions like postherpetic neuralgia and diabetic neuropathy, and preliminary support for cluster headaches and back pain. Zinc works for actual zinc deficiency and shows promise for acne and age-related vision loss.

For the other ingredients in this product — white willow bark, the proprietary blends, wakame, griffonia, and the iodine-containing compounds — we don't have effectiveness ratings on file.

The evidence, ingredient by ingredient Capsicum Niacinamide Zinc

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Niacinamide and cayenne are generally well tolerated at normal food amounts, but higher supplement doses carry risks. Niacinamide at high doses can cause dizziness, drowsiness, itching, stomach upset, headache, and rash.

Cayenne commonly causes belching, bloating, burning in the stomach, diarrhea, nausea, and skin flushing — and large amounts can harm your stomach lining. Zinc is safe below 40 mg daily but can cause stomach cramps, diarrhea, a metallic taste, and nausea; very high doses over time may lead to copper deficiency.

For pregnancy, normal dietary amounts of niacinamide are fine, but high-dose supplements should not be used without a doctor's approval. Safety data for cayenne and zinc supplements during pregnancy and breastfeeding is not well established — talk with your doctor or pharmacist if you're pregnant or nursing.

Cayenne6 drug types · 239 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, capsicum may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro research shows that capsicum might increase the effects of antiplatelet drugs. Also, population research shows that capsicum is associated with an increased risk of self-reported bleeding in patients taking warfarin. However, clinical research shows that taking a single dose of capsaicin (Asian Herbex Ltd.), the active ingredient in capsicum, 400-800 mcg orally in combination with aspirin 500 mg does not decrease platelet aggregation when compared with taking aspirin 500 mg alone. Also, there was no notable effect on measures of platelet aggregation with capsaicin. It is unclear whether capsaicin must be used in more than a single dose to affect platelet aggregation.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking capsicum with antidiabetes drugs might increase the risk of hypoglycemia.
Preliminary clinical research shows that consuming capsicum 5 grams along with a glucose drink attenuates the rise in plasma glucose after 30 minutes by 21%, decreases the 2-hour postprandial area under the curve of plasma glucose by 11%, and increases the 2-hour postprandial area under the curve of plasma insulin by 58% in healthy individuals when compared with placebo. Other clinical research shows that taking capsicum 5 mg daily for 28 days significantly reduces postprandial blood glucose and insulin levels, but not fasting blood glucose and insulin levels, in patients with gestational diabetes.

Likelihood Possible Evidence B
Aspirin

Theoretically, taking capsicum with aspirin might reduce the bioavailability of aspirin.
Animal research shows that acute or chronic intake of capsicum pepper reduces oral aspirin bioavailability. This has not been shown in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, taking capsicum with theophylline might increase the levels and adverse effects of theophylline.
In animal research, oral administration of capsicum reduced excretion of theophylline. However, capsicum does not seem to affect the pharmacokinetics of theophylline when administered intravenously.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, using topical capsaicin may increase the risk of ACE inhibitor-induced cough.
There is one case report of a topically applied capsaicin cream contributing to the cough reflex in a patient using an ACEI. However, it is unclear if this interaction is clinically significant.

Likelihood Unlikely Evidence D
Ciprofloxacin (Cipro)

Theoretically, taking capsicum with ciprofloxacin might increase levels and adverse effects of ciprofloxacin.
Animal research shows that concomitant use of capsaicin, the active constituent of capsicum, and ciprofloxacin increases the bioavailability of ciprofloxacin by up to 70%.

Likelihood Possible Evidence D
Cayenne full monograph & interactions

Niacinamide4 drug types · 124 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, niacinamide may have additive effects when used with anticoagulant or antiplatelet drugs, especially in patients on hemodialysis.
Several cases of thrombocytopenia have been reported for hemodialysis patients treated with niacinamide 1 gram daily. Hemodialysis patients receiving niacinamide had almost a three-fold higher risk of developing thrombocytopenia when compared with those receiving placebo.

Likelihood Unlikely Evidence D
Carbamazepine (Tegretol)

Niacinamide might increase the levels and adverse effects of carbamazepine.
Plasma levels of carbamazepine were increased in two children given high-dose niacinamide, 60-80 mg/kg/day. This might be due to inhibition of the cytochrome P450 enzymes involved in carbamazepine metabolism. There is not enough data to determine the clinical significance of this interaction.

Likelihood Possible Evidence D
Primidone (Mysoline)

Niacinamide might increase the levels and adverse effects of primidone.
Case reports in children suggest niacinamide 60-100 mg/kg/day reduces hepatic metabolism of primidone to phenobarbital, and reduces the overall clearance rate of primidone; however, there is not enough data to determine the clinical significance of this potential interaction.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is limited evidence that niacinamide may increase the anticoagulant effects of warfarin.
In a case report, a patient on warfarin developed an elevated international normalized ratio (INR) of 8.4 after taking niacinamide 500 mg twice daily for 10 days. The patient's INR was previously stable, ranging between 2 and 3, with no other changes to current medications or diet reported. The elevated INR returned to the therapeutic range after receiving vitamin K and discontinuing niacinamide.

Likelihood Possible Evidence D
Niacinamide full monograph & interactions

Zinc Arginate Chelate10 drug types · 67 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Theoretically, zinc might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after zinc containing products.

Likelihood Probable Evidence D
Cephalexin (Keflex)

Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose. To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin. It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.

Likelihood Possible Evidence D
Integrase Inhibitors

Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Zinc is a divalent cation. Pharmacokinetic studies have shown that other divalent cations such as calcium and iron can decrease blood levels of the integrase inhibitor dolutegravir through chelation.

Likelihood Possible Evidence D
Penicillamine (Cuprimine, Depen)

Zinc might reduce the levels and clinical effects of penicillamine.
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated. Advise patients to take zinc and penicillamine at least 2 hours apart.

Likelihood Probable Evidence B
Quinolone Antibiotics

Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Quinolones form complexes with zinc in the gastrointestinal tract, reducing absorption of both the quinolone and zinc if taken at the same time. Advise patients to take these drugs at least 2 hours before, or 4-6 hours after, zinc supplements.

Likelihood Probable Evidence B
Ritonavir (Norvir)

Zinc modestly reduces levels of ritonavir.
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption. In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16%. However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Zinc might reduce levels of tetracycline antibiotics.
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time. Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40%. Demeclocycline and minocycline cause a similar interaction. However, doxycycline does not seem to interact significantly with zinc. Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Likelihood Probable Evidence B
Amiloride (Midamor)

Amiloride can modestly reduce zinc excretion and increase zinc levels.
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses. The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.

Likelihood Probable Evidence B
Atazanavir (Reyataz)

Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption. Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication.

Does Stimulant Free Fat Burner by Cellucor interact with any medications?
Yes. Based on its ingredients, Stimulant Free Fat Burner has a known interaction with 306 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Stimulant Free Fat Burner contains 9 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.
Is this safe to take if I'm on warfarin or another blood thinner?
No. Niacinamide in this product may increase how much your blood thinner works, raising your bleeding risk. One patient's INR (a measure of blood thinning) jumped to a dangerous level after taking niacinamide for just 10 days. Talk to your doctor or pharmacist before using any fat burner while on blood thinners.
Can I take this if I'm on antibiotics?
It depends on which antibiotic. Zinc in this product can reduce how well your body absorbs quinolones, tetracyclines, and cephalexin. Talk with your pharmacist about the specific antibiotic you're taking — you may need to separate doses by several hours.
What are the most common side effects from the ingredients in this product?
Niacinamide may cause dizziness, drowsiness, itching, stomach upset, headache, or rash at higher doses. Cayenne commonly causes belching, bloating, stomach burning, diarrhea, nausea, and skin flushing. Zinc can cause stomach cramps, diarrhea, metallic taste, nausea, and vomiting, especially at higher doses.
Is there evidence this product actually works for fat burning?
We don't have an overall effectiveness rating for this combination product. We do know that some individual ingredients like cayenne have some support for various health uses, but the specific claim of fat burning isn't covered in our data.
Can I take this while pregnant or breastfeeding?
Normal dietary amounts of niacinamide during pregnancy are considered acceptable. However, high-dose supplements of niacinamide, cayenne, and zinc during pregnancy and breastfeeding aren't well studied. Talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.
What ingredients can't you check for interactions?
We don't have interaction data on file for white willow bark extract, 3-iodotyrosine, wakame extract, griffonia seed extract, methylselenocysteine, or 3,5 diiodotyrosine. Your pharmacist may be able to help you find additional safety information on these.
