Humann Superbeets Heart Chews and Acetaminophen, Chlorpheniramine, Codeine, Phenylephrine

These two interact in 4 distinct ways. Each one is explained separately below.

Why Are There 4 Interactions?

Humann Superbeets Heart Chews interacts with whole categories of medication. Acetaminophen, Chlorpheniramine, Codeine, Phenylephrine falls into 4 of those categories, so it can interact with Humann Superbeets Heart Chews in 4 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 4

Why this applies to Acetaminophen, Chlorpheniramine, Codeine, Phenylephrine

Acetaminophen, Chlorpheniramine, Codeine, Phenylephrine 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 a prodrug. Your liver uses an enzyme called CYP2D6 to turn codeine into morphine, which is what actually relieves pain and quiets a cough. The grape seed extract in SuperBeets Heart Chews may mildly slow that same enzyme in lab studies. If it did that in your body, you would convert less codeine into morphine, so you might get less pain or cough relief, not more.

Honestly though, this is a very weak, theoretical concern. It comes from test-tube data, not real people, and the supplement dose of grape seed extract is small. I would not expect a noticeable change. If your cough or pain medicine seems less effective, just mention it to your pharmacist or doctor.

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 4

Acetaminophen, Chlorpheniramine, Codeine, Phenylephrine also falls under Cytochrome P450 3A4 (Cyp3A4) 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 CYP3A4 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 explains PharmD, Clinical Pharmacist

This combo cold-and-cough product has a few moving parts, and one of them, codeine, is a prodrug. Your body turns codeine into morphine mainly through a different enzyme (CYP2D6), not CYP3A4, so the grape seed extract in these chews isn't likely to change how much pain relief or drowsiness you get from it.

The concern on file is that grape seed extract might mildly slow CYP3A4, which helps clear codeine and some other compounds. In theory that could nudge levels up a touch, meaning slightly more sleepiness, dizziness, or constipation. But honestly, this is lab-dish data only, with no real human cases reported, so the risk is small. Still, if you feel extra drowsy or off, check with your pharmacist or doctor.

Cytochrome P450 2E1 (Cyp2E1) Substrates

Acetaminophen, Chlorpheniramine, Codeine, Phenylephrine 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.

The piece of this combo cold-and-cough product that touches CYP2E1 is the acetaminophen (the Tylenol part). The grape seed extract in SuperBeets Heart Chews has shown, in lab dishes only, a mild ability to slow that enzyme. In theory, slower metabolism could nudge acetaminophen levels up a little. The reassuring news: this is rated minor and unlikely, with no real-world human reports behind it, so for most people taking normal doses it just isn't something to lose sleep over.

The bigger thing I'd watch is overlap. Acetaminophen shows up in many products, so don't double up and exceed the daily limit. And the codeine and chlorpheniramine can already cause drowsiness. If you have liver concerns or take this often, run it by your pharmacist.

Here's the piece worth knowing: the acetaminophen in your Colrex combo is partly broken down by an enzyme called CYP2E1. The grape seed extract in SuperBeets Heart Chews may, based only on lab studies, slow that enzyme down a little. In theory, that could let acetaminophen clear a touch more slowly. On its own this is a minor point, since the bigger acetaminophen concern is always total daily dose, not this enzyme.

Honestly, there are no real human reports of this happening, so I wouldn't lose sleep over it. The other ingredients (codeine, chlorpheniramine, phenylephrine) aren't the focus here. Just keep an eye on your acetaminophen total from all sources, and check with your pharmacist if you take this product regularly.
