Humann Superbeets Heart Chews and Isradipine

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. Isradipine 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 Isradipine

Isradipine 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: Isradipine is a calcium channel blocker that lowers your blood pressure by relaxing and widening your blood vessels. The beetroot in SuperBeets Heart Chews works through a different path (nitric oxide), but it can also gently relax those same vessels. So you're essentially nudging blood pressure down from two directions at once.

The good news is this overlap is considered minor. Studies show the blood pressure effect from beet nitrates is usually small and short-lived. The main thing to watch for is a little extra dizziness, lightheadedness, or feeling faint when you stand up, since isradipine can already cause that on its own. If you notice this, especially early on, mention it to your pharmacist or doctor before changing anything.

Minor

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 2

Isradipine 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 with these chews and your isradipine. The grape seed extract in SuperBeets (about 150mg per serving) may slightly block CYP3A4, the liver enzyme that breaks down isradipine. If that enzyme slows down, your body clears the drug a little less efficiently, so levels could nudge upward. Isradipine isn't a prodrug, so more drug in your system simply means a stronger blood-pressure-lowering effect and possibly more of its usual side effects like dizziness, flushing, headache, ankle swelling, or a faster heartbeat.

That said, I don't want to overstate this. The concern comes only from lab studies, and there are no reported cases in real people. On top of that, beets themselves may gently lower blood pressure. Just keep an eye out for lightheadedness, and check with your pharmacist or doctor before starting these chews.

From our pharmacist’s overview on the Isradipine page

“Grapefruit is the first thing I mention to anyone taking isradipine (Dynacirc CR). This blood pressure medicine is cleared by an enzyme called CYP3A4, and grapefruit blocks that enzyme, so drug levels can climb and blood pressure can fall further than intended.”
