Humann Superbeets Heart Chews and Acetaminophen, Chlorzoxazone, Codeine

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Humann Superbeets Heart Chews interacts with whole categories of medication. Acetaminophen, Chlorzoxazone, Codeine falls into 3 of those categories, so it can interact with Humann Superbeets Heart Chews in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Minor).

Minor

Cytochrome P450 2D6 (Cyp2D6) Substrates

1 of 3

Why this applies to Acetaminophen, Chlorzoxazone, Codeine

Acetaminophen, Chlorzoxazone, Codeine falls under Cytochrome P450 2D6 (Cyp2D6) Substrates — the group Humann Superbeets Heart Chews interacts with.

Each serving of HumanN SuperBeets includes 150mg of grape seed extract (2 chews). Laboratory studies suggest that grape seed extract might have inhibitory effects on the CYP2D6 metabolizing enzyme. If this enzyme is inhibited, drugs metabolized by it may undergo slower metabolism, potentially leading to (in many cases) higher-than-normal drug levels. Elevated drug levels can increase the risk of experiencing side effects. However, it's crucial to highlight that, as of now, there is no documented or reported instance of this specific interaction occurring in human studies.

Here's the wrinkle with this combo product: the codeine part is what interacts with the grape seed extract in SuperBeets. Codeine is a prodrug, meaning your body has to switch it on using an enzyme called CYP2D6 before it works as a pain reliever. Lab studies hint that grape seed extract might slow that same enzyme down. If it did, your body could activate less codeine, so you might get weaker pain relief rather than stronger effects.

The good news is this is a very minor, unlikely concern. It comes from test-tube research only, with no real cases reported in people, and the amount of grape seed extract in a couple of chews is small. The acetaminophen and chlorzoxazone parts aren't really affected. Still, if your pain isn't well controlled, mention it to your pharmacist or doctor.

Cytochrome P450 2E1 (Cyp2E1) Substrates

2 of 3

Acetaminophen, Chlorzoxazone, Codeine also falls under Cytochrome P450 2E1 (Cyp2E1) Substrates.

Each serving of HumanN SuperBeets includes 150mg of grape seed extract (2 chews). Laboratory studies suggest that grape seed extract might have inhibitory effects on the CYP2E1 metabolizing enzyme. If this enzyme is inhibited, drugs metabolized by it may undergo slower metabolism, potentially leading to (in many cases) higher-than-normal drug levels. Elevated drug levels can increase the risk of experiencing side effects. However, it's important to point out that there is no documented or reported instance of this specific interaction occurring in human studies.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combo pill includes chlorzoxazone, a muscle relaxer that your body partly breaks down using an enzyme called CYP2E1. The grape seed extract in SuperBeets Heart Chews might slow that enzyme down a bit, at least based on lab studies. In theory, that could let chlorzoxazone build up slightly, which might mean more drowsiness, dizziness, or a groggy feeling. The acetaminophen and codeine parts aren't really driven by this same pathway.

Here's the reassuring part: this is rated as a minor and unlikely interaction, and it has never actually been reported in real people, only suggested in test-tube work. So I wouldn't lose sleep over it. Still, if you take this regularly, mention it to your pharmacist or doctor just to be safe.

Here's the piece that matters for this combo product. The grape seed extract in SuperBeets Heart Chews may, based only on lab studies, slow down an enzyme called CYP2E1. In your medication, chlorzoxazone (the muscle relaxer) is the ingredient most cleared by that enzyme. In theory, if it's processed more slowly, levels could creep up a bit, which might mean more drowsiness, dizziness, or stomach upset.

Honestly though, this is a very weak, unlikely concern. There are no real-world reports of it actually happening in people. The acetaminophen and codeine parts aren't the main worry here. If you're using these chews regularly, just mention it to your pharmacist or doctor so they can keep an eye on how you feel.
