HelloPharmacist Scorecard of Carb Blocker by Applied Nutrition
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
Applied Nutrition's Carb Blocker has two active ingredients: chromium and white kidney bean extract. Chromium is a mineral that plays a role in how your body handles blood sugar and may support insulin function.
White kidney bean extract is derived from the legume and is often used in carb-blocking supplements, though we hold limited interaction data for it. The tablet also contains inactive ingredients — fillers and binders like calcium phosphate, stearic acid, and magnesium stearate that help hold the tablet together.
Does it work?
Moderate evidence
The evidence for chromium is mixed. It's likely effective for treating a true chromium deficiency, which is rare.
For type 2 diabetes, the evidence suggests it may possibly help — some research shows it can lower blood glucose, especially in people whose diabetes isn't well controlled. For prediabetes (impaired glucose tolerance), high blood pressure, and schizophrenia, the evidence is too weak or negative to support its use.
The facts we hold don't include specific effectiveness data for the white kidney bean extract in this product.
How safe is it?
Well-documented data
Chromium is generally well tolerated at typical supplement doses. The most common side effects are stomach irritation, headaches, insomnia, irritability, and mood changes.
Skin rashes, itching, and hives have been reported, especially in people with a chromium contact allergy. Rare but serious effects — kidney or liver damage, muscle breakdown, and low platelet counts — have been documented, mostly with high or long-term doses.
For pregnancy, small amounts from food or prenatal vitamins are generally considered acceptable, but extra chromium supplements should be avoided unless your doctor recommends it. The safety data for higher supplement doses is limited.
For breastfeeding, limited data suggest it's likely safe, but talk with your doctor for personalized advice.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist if you take insulin or any antidiabetes medications — chromium may lower your blood sugar further and increase hypoglycemia risk. Also flag levothyroxine (thyroid medication) and any NSAIDs or aspirin you use regularly.
These interactions are moderate to minor, but your pharmacist needs to know.
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 Blocker may be worth considering if you're interested in chromium's blood-sugar effects, but it's not a decision to make alone — especially if you take insulin, antidiabetes drugs, or levothyroxine. Those medications need your pharmacist's go-ahead.

Carb Blocker by Applied Nutrition Drug Interactions
HelloPharmacist Interaction Report
Applied Nutrition's Carb Blocker contains chromium, which does interact with several medication types.
The most serious concern is with antidiabetes drugs and insulin — chromium may add to their blood-sugar-lowering effect and raise your risk of low blood sugar (hypoglycemia). If you take insulin or any diabetes medication, your doctor may need to monitor your blood sugar more closely or adjust your dose.
Read the full breakdown — every affected drug type, severity by severity
Chromium also interacts with levothyroxine (thyroid hormone, brand Synthroid and others). Research shows it can reduce how much levothyroxine your body absorbs — one study found a 17% drop in blood levels when taken together.
Your thyroid medication may work less well. Taking them at least several hours apart may help, but check with your pharmacist or doctor first.
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin may increase how much chromium your body absorbs and retains, though the effects are minor. Altogether, these interactions span 178 individual medications.
We could not check the white kidney bean extract ingredient — we hold no interaction data for it. Run your exact medications through the tool on this page before you start.

For each ingredient in Carb Blocker 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.
Chromium
Antidiabetes Drugs
Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.
Insulin
Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,
Levothyroxine (Synthroid, Others)
Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.
Aspirin
Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)
NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.
