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 4 of its 4 active ingredients.
  • “Gymnema sylvestre Leaf Extract” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.
  • “Citrin” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.

Carb Arrest has 4 active ingredients aimed at supporting carbohydrate metabolism and weight management. Chitosan is a fiber derived from shellfish that's designed to bind dietary fats.

Gymnema sylvestre Leaf Extract, Gymnemic Acid, Hydroxycitric Acid, and Phase 2 (a proprietary ingredient) round out the formula. The product also contains cellulose as an inactive ingredient.

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: reduce calorie absorption and support weight control.
  • We looked for evidence on: Obesity, Metabolic syndrome, Hypercholesterolemia, Hyperlipidemia, Impaired glucose tolerance (prediabetes), appetite suppression — and 2 related terms.
  • The strongest evidence on file: Chitosan is rated "Possibly Effective" for Obesity (Natural Medicines).
  • Also on file: Chitosan is rated "Insufficient Reliable Evidence To Rate" for Hypercholesterolemia.
  • Also on file: Garcinia is rated "Insufficient Reliable Evidence To Rate" for Hyperlipidemia, Obesity.

The data we hold covers chitosan's effectiveness for several conditions. It's possibly effective for obesity and may help with postoperative recovery and high blood pressure.

For Crohn disease and dry eye, the evidence isn't established enough to rate. We don't have effectiveness ratings on file for the other active ingredients in this product.

The evidence, ingredient by ingredient Gymnema Garcinia Chitosan

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.

Chitosan is generally well tolerated in the short term, though quality evidence is limited. The most common side effects are constipation, diarrhea, gas, stomach discomfort, and nausea.

Because chitosan is derived from shellfish, it's a concern if you have a shellfish allergy. One person with kidney failure reported itching during chitosan use, though it's unclear if chitosan was the cause.

There isn't enough safety data to use this product during pregnancy or while breastfeeding. Talk with your pharmacist or doctor for personalized advice if you're pregnant, planning to become pregnant, or nursing.

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?
  • 2 of the 2 matched ingredients can interact with medications — Chitosan, Garcinia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 706 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 you take Carb Arrest, check your medications against these two: warfarin (Coumadin), a blood thinner, where chitosan may increase bleeding risk (Moderate severity), and acyclovir (Zovirax), an antiviral, where chitosan may reduce how well it's absorbed (Moderate severity). We couldn't check three ingredients — Hydroxycitric Acid, Gymnemic Acid, and Phase 2 — because we don't hold interaction data for them.

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.

Carb Arrest may be an option if you're looking to support weight management and carb intake, but it's not right for everyone. If you take warfarin or acyclovir, you'll need to check with your pharmacist first.

Anyone with a shellfish allergy should avoid it. Pregnant or breastfeeding?

Talk to your pharmacist before starting.

Gymnema sylvestre Leaf Extract6 drug types · 851 drugs

Antidiabetes Drugs

Theoretically, taking gymnema with antidiabetes drugs might increase the risk of hypoglycemia.
Gymnema reduces blood glucose levels in some human and animal research. In human studies, it has been shown to enhance the blood glucose lowering effects of hypoglycemic drugs. However, other research in adults with prediabetes or metabolic syndrome suggests that gymnema does not reduce fasting levels of blood glucose. Until more is known, monitor blood glucose levels closely.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP1A2.
Animal and in vitro research shows that gymnema can inhibit the CYP1A2 enzyme. In one animal study, oral administration of gymnema for 7 days increased the plasma concentrations of phenacetin, a CYP1A2 substrate, by about 1.4-fold and reduced the clearance of phenacetin by about 29%.

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

Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9.
Animal research shows that gymnema can induce the CYP2C9 enzyme. In one animal study, gymnema caused a 2.4-fold increase in the clearance of tolbutamide, a CYP2C9 substrate, in rats. In vitro research also shows that gymnema can inhibit CYP2C9.

Likelihood Possible Evidence D
Phenacetin

Theoretically, taking gymnema with phenacetin might increase the levels of phenacetin.
Animal research shows that gymnema, administered orally for 7 days, decreases the clearance of phenacetin in a dose-dependent manner by about 21% to 29% and increases plasma levels about 1.3- to 1.4-fold when compared to control.

Likelihood Possible Evidence D
Tolbutamide (Orinase)

Theoretically, taking gymnema with tolbutamide might the decrease levels of tolbutamide.
Animal research shows that gymnema, administered orally for 7 days, increases the clearance of tolbutamide by 2.4-fold when compared to control.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP3A4.
One in vitro study using rat liver microsomes shows that gymnema can modestly inhibit the CYP3A4 enzyme. However, other in vitro research using human liver microsomes shows that gymnema does not affect CYP3A4 activity. Animal research also shows that gymnema does not alter the function of CYP3A4. In one study in rats, oral administration of gymnema for 7 days did not alter the clearance of amlodipine, a CYP3A4 substrate.

Likelihood Unlikely Evidence D
Gymnema sylvestre Leaf Extract full monograph & interactions

Citrin4 drug types · 704 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, hydroxycitric acid (HCA), the main active ingredient in garcinia, might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
HCA inhibits platelet aggregation in vitro. The inhibitory effect seems to be greater in platelets extracted from diabetic subjects than non-diabetic subjects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, hydroxycitric acid (HCA), the main active ingredient in garcinia, might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
HCA reduces fasting and postprandial blood glucose levels in animal models, theoretically by delaying glucose absorption. This effect has not been reported in humans.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use with other potentially hepatotoxic drugs might increase the risk of developing liver damage.
There have been reports of acute hepatitis with elevated liver enzymes associated with garcinia, when taken alone or in combination with other ingredients. Case reports collected from the Drug Induced Liver Injury Network suggest this risk may be greater in people who carry the HLA B*35:01 allele.

Likelihood Possible Evidence D
Serotonergic Drugs

Theoretically, combining garcinia with other serotonergic drugs might increase the risk of serotonergic side effects, including serotonin syndrome.
In one report, a patient experienced serotonin syndrome after taking garcinia extract (60% hydroxycitric acid) 1000 mg daily in combination with escitalopram 20 mg, which had been taken for a year. The patient was switched to sertraline 50 mg daily and again experienced serotonin syndrome.

Likelihood Possible Evidence D
Citrin full monograph & interactions

Chitosan2 drug types · 3 drugs

Acyclovir (Zovirax)

Chitosan can reduce the absorption of acyclovir, potentially increasing the risk for treatment failure.
Clinical research in humans shows that taking chitosan along with acyclovir 200 mg reduces acyclovir absorption. Concomitant administration of chitosan 400 mg or 1000 mg reduced the acyclovir area under the curve (AUC) and peak plasma concentration by about 30% and 40%, respectively, compared with control. Concomitant administration with chitosan 1000 mg also increased time to peak concentration from 1 hour to 2 hours. In vitro research suggests that the mechanism for reduced absorption is due to acyclovir entrapment in chitosan-mucus complexes, which reduces intestinal absorption.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, chitosan might increase the risk of bleeding when taken with warfarin.
In a case report, a patient taking warfarin had a significantly increased international normalized ratio (INR) after starting chitosan 1200 mg daily. The INR normalized after chitosan was discontinued and vitamin K was administered. The patient once again started taking chitosan and again had a significant increase in INR. The INR stabilized again once chitosan was discontinued. Researchers theorize that this interaction might occur because chitosan decreases absorption of fat-soluble vitamins, including vitamin K, which could increase the anticoagulant effect of warfarin.

Carb Arrest by Viva Vitamins: Common Questions

Does Carb Arrest by Viva Vitamins interact with any medications?
Yes. Based on its ingredients, Carb Arrest has a known interaction with 1,136 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Carb Arrest 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.
Is Carb Arrest safe if I have a shellfish allergy?
No. One of the active ingredients, chitosan, is derived from shellfish, so it's a real concern for anyone with that allergy. Skip this product and talk to your pharmacist about alternatives.
What are the most common side effects?
Constipation, diarrhea, gas, stomach discomfort, and nausea. Some people also report dryness of the throat or excess fat in their stool. These tend to happen in the short term as your body adjusts.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data to recommend it either way. Talk with your pharmacist or doctor — they can help you decide if this is right for your situation.
Does Carb Arrest actually work for weight loss?
Chitosan, the main ingredient we have data for, is possibly effective for obesity. That said, the evidence is limited, and it works best alongside diet and exercise, not on its own.
What does chitosan actually do?
Chitosan is a type of fiber that's designed to bind dietary fats in your gut so your body can't absorb them as easily. That's why the most common side effects are digestive — it affects how your body processes fat.
