Humann Superbeets Heart Chews and Dextromethorphan, Methscopolamine, Phenylephrine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Humann Superbeets Heart Chews interacts with whole categories of medication. Dextromethorphan, Methscopolamine, Phenylephrine falls into 2 of those categories, so it can interact with Humann Superbeets Heart Chews in 2 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 2

Why this applies to Dextromethorphan, Methscopolamine, Phenylephrine

Dextromethorphan, Methscopolamine, 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.

The piece of this combo worth talking about is the dextromethorphan (the cough suppressant). Your body relies on a liver enzyme called CYP2D6 to clear it. The grape seed extract in these chews has shown some ability to slow that enzyme in lab dishes, so in theory dextromethorphan could clear a bit more slowly and build up. If that happened, you might notice more of its usual effects, like drowsiness, dizziness, or feeling a little foggy.

Here is the reassuring part: this is only a laboratory finding, rated minor and unlikely, with no real-world cases on record. For most people it is not something to lose sleep over. Still, if you take these chews regularly, it never hurts to run it by your pharmacist or doctor first.

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 2

Dextromethorphan, Methscopolamine, 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.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the short version: the grape seed extract in SuperBeets Heart Chews might slow down a liver enzyme called CYP3A4 in lab studies. The dextromethorphan part of your cold combo (the cough suppressant) leans partly on that enzyme to be cleared from your body. So in theory, if it breaks down a bit slower, you could see slightly more of dextromethorphan's usual effects, things like drowsiness, dizziness, or feeling foggy.

That said, I don't want you to lose sleep over this. The evidence here is weak (mostly test-tube data), there are no real-world reports of it happening, and it's rated as a minor and unlikely interaction. If you ever feel unusually sleepy or off after taking both, just check in with your pharmacist or doctor first before changing anything.

From our pharmacist’s overview on the Dextromethorphan, Methscopolamine, Phenylephrine page

“Dextromethorphan with methscopolamine and phenylephrine (DA Chewable) packs a cough suppressant, a drying agent, and a decongestant into one tablet, which gives supplements several distinct ways to cause trouble, so I treat this as a list deserving real caution. Grapefruit can drive levels of the drug up by blocking its breakdown, St.”
