HelloPharmacist Scorecard of Fat & Carb Blocker 400 mg by SuperSmart

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: ID-alG, a proprietary extract from Ascophyllum nodosum, a brown seaweed. The supplement also includes acacia gum as an inactive ingredient.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Ascophyllum Nodosum's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Fat and carbohydrate absorption blocking.
  • We looked for evidence on: Obesity, Metabolic syndrome, Impaired glucose tolerance (prediabetes), Weight management, Glycemic control.
  • The closest evidence on file: Ascophyllum Nodosum is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).
  • Also on file: Ascophyllum Nodosum is rated "Insufficient Reliable Evidence To Rate" for Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence we hold doesn't support claims about this ingredient for prediabetes, obesity, reflux disease, iodine deficiency, or inflammatory bowel disease — the data for all of these is insufficient to rate. That means either there's not enough quality research yet, or the studies don't show a clear benefit.

If you're considering this for any of those reasons, talk with your pharmacist about what the current science actually shows.

The evidence, ingredient by ingredient Ascophyllum Nodosum

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ascophyllum nodosum is used in food, but its iodine content requires caution, and the supplement may contain heavy metals from seawater. The safety data advises against use during pregnancy and breastfeeding due to high iodine levels and possible contaminants that can affect the baby or pass into breast milk.

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 1 matched ingredient can interact with medications — Ascophyllum Nodosum.
  • The most serious interaction on file is rated Moderate.
  • For scale: 22 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 before you start if you take antithyroid drugs, thyroid hormone (like levothyroxine), or amiodarone. All three are affected by the iodine in this supplement, and the effects could shift how well your medication works.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This is a single-ingredient seaweed supplement mainly of interest if you're exploring weight or blood-sugar support — though the evidence for those uses isn't established. If you take any thyroid or heart medications, check with your pharmacist first; the iodine here could interfere.

Pregnancy and breastfeeding are contraindicated.

ID-alG3 drug types · 22 drugs

Amiodarone (Cordarone)

Theoretically, combining Ascophyllum nodosum with amiodarone might cause excessively high iodine levels.
Ascophyllum nodosum contains iodine, although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Due to its iodine content, Ascophyllum nodosum might alter the effects of antithyroid drugs.
Ascophyllum nodosum contains iodine, although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Ascophyllum nodosum while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Ascophyllum nodosum might alter the effects of thyroid hormone.
Ascophyllum nodosum contains iodine, although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history.

Fat & Carb Blocker 400 mg by SuperSmart: Common Questions

Does Fat & Carb Blocker 400 mg by SuperSmart interact with any medications?
Yes. Based on its ingredients, Fat & Carb Blocker 400 mg has a known interaction with 22 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fat & Carb Blocker 400 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is ID-alG and where does it come from?
ID-alG is an extract from Ascophyllum nodosum, a brown seaweed. It's used in this supplement because seaweed naturally contains iodine and other compounds that some products market for weight or blood-sugar support.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advises against use in both pregnancy and breastfeeding because of the high iodine content and possible contaminants that could affect your baby or pass into breast milk. Talk with your OB or midwife about your options.
Does this supplement actually help with weight loss or blood sugar?
The evidence we hold doesn't show it does. For prediabetes, obesity, and related conditions, the data on this ingredient rates as insufficient — meaning either there aren't enough solid studies, or the ones we have don't demonstrate a clear benefit.
What side effects has this been reported to cause?
In one small trial, a few participants taking the powder form developed elevated levels of thyroid-stimulating hormone (TSH) — the body's signal that thyroid function is shifting. This is one reason people on thyroid medications need to check with their pharmacist first.
Are there any fillers or other inactive ingredients I should know about?
Yes, the capsule contains acacia gum as an inactive ingredient. If you have a gum sensitivity, mention it when you check with your pharmacist.
