Humann Superbeets Heart Chews and Methadone

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. Methadone 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 Methadone

Methadone 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.
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 explains PharmD, Clinical Pharmacist

Here's the gist. The grape seed extract in these chews has shown, in lab dish studies only, a mild ability to slow down an enzyme called CYP2D6. Some of your methadone is handled by that enzyme, so in theory, blocking it could let methadone build up a little. Since methadone is an active drug (not a prodrug that needs switching on), higher levels could mean more of its usual effects, like extra drowsiness, slowed breathing, constipation, or dizziness.

That said, I don't want to scare you. This is rated minor and unlikely, methadone is actually cleared mostly by other enzymes, and there are no real reports of this happening in people. Still, because methadone is a powerful medicine where small changes matter, please run it by your pharmacist or prescriber before adding these chews.

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 2

Methadone 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 is the gist for Methadone. The grape seed extract in these chews might slow down CYP3A4, one of the liver enzymes that helps break down methadone. In theory, if that enzyme is blocked, methadone could clear a little more slowly and build up a bit, which could nudge up its effects and side effects like drowsiness, slowed breathing, constipation, or feeling foggy.

That said, this is a very weak, lab-only concern. There are no real human reports of this actually happening, and the amount of grape seed extract in a couple of chews is small. Still, methadone is a medicine where even modest changes deserve respect, so I would simply mention these chews to your pharmacist or prescriber before adding them rather than worrying.

  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).

About Methadone

What Is Methadone Used For?

Brand name: Dolophine

Methadone treats severe and persistent pain that requires daily, around-the-clock, long-term opioid treatment and cannot be managed adequately with other options. It is available in several forms for this use, including oral solution, oral tablets, oral concentrate, and injectable forms (intravenous, intramuscular, and subcutaneous). Injectable methadone is not approved for outpatient pain treatment — it is reserved for hospitalized patients unable to take oral medication.

Methadone is also used for the detoxification and maintenance treatment of opioid addiction (dependence on heroin or other morphine-like drugs). Oral forms — including tablets, dispersible tablets (such as Methadose Dispersible and DISKETS), and oral concentrates (such as Methadone Hydrochloride Intensol™, Methadose, and others) — are approved for this use. By law, methadone for opioid addiction treatment must be dispensed only by certified opioid treatment programs. Injectable methadone is not approved for outpatient addiction treatment.
