Humann Superbeets Heart Chews and Ambrisentan

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. Ambrisentan 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

Antihypertensive Drugs

1 of 2

Why this applies to Ambrisentan

Ambrisentan falls under Antihypertensive Drugs — the group Humann Superbeets Heart Chews interacts with.

Each serving of HumanN SuperBeets includes 500mg of beetroot powder (2 chews). Beetroot is rich in nitrates, which have the potential to widen blood vessels (vasodilation) and, in turn, possibly lower blood pressure. While there is a theoretical concern about the nitrate content in beets causing a blood pressure drop, research consistently indicates that any impact is generally minor and short-lived. However, it's crucial to be aware that blood pressure medications alone can cause dizziness and lightheadedness. Combining them with beet supplements might heighten the risk of experiencing these side effects due to the temporary vasodilation caused by the nitrates in beet.
Severity Minor Likelihood Possible Evidence A

Interaction 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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: ambrisentan (Letairis or Volibris) treats high pressure in your lung arteries by relaxing and opening those blood vessels. The beetroot in SuperBeets Heart Chews works through nitric oxide, which also tends to relax blood vessels a little. So you've got two things gently nudging blood pressure in the same direction. There's no metabolism clash here, ambrisentan isn't a prodrug and the chews don't change how your liver handles it. It's really about the combined relaxing effect.

In practice this interaction is rated minor, and any blood pressure dip from beets is usually small and short-lived. The main thing to watch for is extra dizziness or lightheadedness, especially when standing up quickly. If you notice that, mention it to your pharmacist or doctor before changing anything.

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 2

Ambrisentan 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 gist for Letairis (ambrisentan). Your liver uses an enzyme called CYP3A4 to help clear this medication. The grape seed extract in SuperBeets Heart Chews (about 150mg per two chews) has shown some ability to slow that enzyme down, but only in lab dish studies, not in real people. In theory, if CYP3A4 slows, ambrisentan could build up a bit and you'd be more likely to notice its usual side effects, things like swelling in your legs or ankles, a stuffy nose, flushing, or feeling lightheaded.

Honestly, this is a weak, theoretical concern, and no actual cases have ever been reported. Beets may also gently lower your blood pressure, which is worth keeping in mind with PAH treatment. I'd just give your pharmacist or doctor a quick heads-up before starting these chews.

About Ambrisentan

What Is Ambrisentan Used For?

Brand names: Letairis, Volibris

Ambrisentan tablets and Letairis tablets are both used to treat pulmonary arterial hypertension (PAH, WHO Group 1) — a condition where the blood pressure in the arteries leading to the lungs is dangerously high. Both are approved to help adults exercise better and slow the worsening of PAH.

Both ambrisentan tablets and Letairis are also approved to be used together with tadalafil (another PAH medicine) to further reduce the risk of disease progression, lower the chance of hospitalization for worsening PAH, and improve exercise ability. Most of the clinical evidence was in patients with mild-to-moderate symptoms and PAH caused by unknown or inherited causes, or PAH linked to connective tissue diseases.
