Understanding Kratom's Impact on Heart Health

Published by Zenhop | Trusted Botanicals. One Place.

Kratom, a tropical plant native to Southeast Asia, has gained increasing popularity in the wellness space for its energizing, calming, and mood-boosting properties. While many users praise its natural benefits, questions around its safety—particularly regarding cardiovascular health—are essential to address with science-backed clarity.

In this article, we dive deep into kratom’s potential impact on heart health. Whether you're a regular kratom user or just curious, this guide will help you understand what current research says, what to watch out for, and how to use kratom responsibly.

 

What Is Kratom? A Quick Overview

Kratom (Mitragyna speciosa) is a natural botanical from the coffee family, traditionally used in countries like Thailand and Indonesia. Its leaves contain active alkaloids, primarily mitragynine and 7-hydroxymitragynine, which interact with receptors in the brain and body to produce stimulant or sedative effects depending on the dose.

Popular uses include:

• Boosting energy and focus

• Supporting pain relief and relaxation

• Enhancing mood and motivation

While kratom is considered a natural herbal supplement, it's important to understand its effects holistically—including its influence on heart health.

How Kratom Affects the Cardiovascular System

1. Blood Pressure

Some studies and anecdotal reports suggest that kratom may influence blood pressure levels.

• Low doses can act as a stimulant, potentially increasing heart rate and blood pressure.

• High doses may have sedative effects, which could lower blood pressure in some individuals.

That said, there is no conclusive clinical evidence showing that kratom directly causes hypertension or chronic low blood pressure. However, those with pre-existing conditions should proceed cautiously.

2. Heart Rate (Tachycardia or Bradycardia)

Kratom’s alkaloids can cause changes in heart rhythm, especially in large doses. Some users have reported tachycardia(rapid heart rate) or palpitations, while others experience no cardiovascular symptoms.

Key Point: Irregular heartbeat is more often reported in cases of kratom overuse or when combined with other substances. Pure, moderate use appears to have less risk.

3. Electrolyte Imbalance and Dehydration

Stimulant-like effects may lead to mild dehydration in some users, particularly if kratom is taken without sufficient water intake. Dehydration can affect electrolyte balance, which in turn influences heart function.

4. Possible Risk Factors from Contaminated Products

One major issue is product purity. Some kratom sold in the U.S. is not third-party tested and may contain contaminants or adulterants (e.g., synthetic opioids or heavy metals), which can negatively impact cardiovascular health.

Always purchase kratom from reputable, lab-tested sources like Zenhop, which only features brands with Certificates of Analysis (COAs) and rigorous quality control.

 

What Do Scientific Studies Say?

As of 2025, human-based clinical studies on kratom’s heart-related effects are limited but growing. Here's a summary of the key findings:

• A 2019 study in Clinical Toxicology reviewed 935 kratom exposures reported to poison control centers. About 20% reported cardiovascular effects, but these were largely tied to polydrug use.

• A 2020 study in Journal of the American Heart Association examined kratom-associated deaths. In most cases, kratom was not the sole cause—other drugs or underlying medical conditions were also involved.

• A 2023 animal study showed temporary increases in blood pressure and heart rate in rodents at extremely high doses, but these effects did not persist over time.

Conclusion: Moderate kratom use in healthy individuals shows low cardiovascular risk, but long-term effects and risks for those with existing heart conditions remain uncertain and need more study.

Who Should Be Cautious with Kratom?

Kratom may not be suitable for everyone. Those in the following groups should consult a healthcare provider before use:

• Individuals with heart disease, high blood pressure, or arrhythmias

• People taking medications that affect heart rhythm

• Anyone with a history of substance use disorder

• Pregnant or nursing women

Zenhop does not recommend kratom for children, pregnant women, or individuals with cardiovascular conditions without medical supervision.

 

Tips for Safer Kratom Use

 -Start Low, Go Slow
Begin with a low dose (1–2 grams) and observe how your body responds.
-Stay Hydrated
Drink plenty of water to reduce the risk of dehydration and electrolyte imbalance.

-Avoid Mixing with Other Substances
Combining kratom with caffeine, alcohol, or stimulants can strain the heart.

-Choose Lab-Tested Products
Always use kratom from reputable vendors like Zenhop, who provide COAs, dosage transparency, and safety information.

-Listen to Your Body
If you experience chest pain, shortness of breath, or rapid heartbeat—stop use immediately and seek medical advice.

Conclusion: Respect Kratom, Protect Your Heart
