By the end of this article, you’ll know exactly why kratom tea is best left off your pregnancy wellness plan and how to move forward with confidence.

What is kratom tea?

Kratom (Mitragyna speciosa) is a tropical evergreen tree native to Southeast Asia. Its leaves contain several active alkaloids, most notably mitragynine and 7‑hydroxymitragynine, which interact with opioid receptors in the brain. Traditionally, people chew fresh leaves or brew them into a tea to gain stimulant effects at low doses (increased alertness, energy) and sedative or analgesic effects at higher doses (pain relief, relaxation). In the United States, kratom is sold in powders, capsules, extracts, and pre‑made teas, often marketed as a “natural” alternative for mood, pain, or fatigue.

Because kratom is not an approved medication, its production is unregulated, leading to variability in alkaloid concentrations and potential contamination with heavy metals, bacteria, or other herbs. While some users report subjective benefits, scientific data on its safety—especially during pregnancy—is sparse. This lack of reliable information is a key reason health authorities urge caution.

Is kratom tea safe during pregnancy?

Potential mechanisms of risk include:

• Opioid receptor activation: Mitragynine can cross the placenta, potentially affecting fetal brain development.
• Maternal side effects: Nausea, vomiting, constipation, and liver enzyme elevations can compromise nutrition and overall health during pregnancy.
• Dependence and withdrawal: Regular use may lead to dependence, and abrupt cessation can trigger withdrawal symptoms that stress both mother and fetus.

Studies on kratom in pregnant animals suggest possible reduced fetal weight and increased neonatal mortality, but human data are limited to case reports and retrospective analyses. Given the unknowns and the presence of safer, evidence‑based options, most experts advise complete avoidance.

What are the potential risks of kratom tea during pregnancy?

When kratom’s alkaloids enter the bloodstream, they can affect both mother and fetus. Documented maternal risks include:

• Gastrointestinal upset (nausea, vomiting), which can exacerbate typical pregnancy symptoms and lead to dehydration.
• Liver toxicity—elevated alanine aminotransferase (ALT) levels have been reported in kratom users, raising concerns about hepatic health during a time when liver function is already taxed.
• Dependence and withdrawal—regular consumption may create a physiological reliance, and abrupt cessation can trigger symptoms such as irritability, sweating, and muscle aches.

Fetal risks are less well‑studied but potentially serious. Animal research indicates possible:

• Reduced birth weight and growth restriction.
• Neurodevelopmental alterations due to opioid‑like activity.
• Increased risk of Neonatal Abstinence Syndrome (NAS) if the newborn is exposed in utero.

Because kratom is not listed in any reputable teratology database as “safe,” the precautionary principle—especially during organ formation in the first trimester—guides the recommendation to avoid it entirely.

Is kratom tea safe during the first, second, or third trimester?

Across all three trimesters, the consensus remains the same: avoid kratom tea. The first trimester is the most critical period for organogenesis; exposure to any substance with unknown teratogenic potential is discouraged. In the second and third trimesters, the concerns shift toward fetal growth, placental transfer, and the possibility of neonatal withdrawal. No trimester‑specific safety threshold has been identified, and the ACOG and NHS guidelines do not differentiate between stages—kratom is simply not recommended at any point in pregnancy.

First trimester (weeks 1–13)

During organ formation, even low‑level exposure to opioid‑acting compounds can theoretically interfere with neural and organ development. The lack of human data means any exposure is considered a potential risk. If you’ve already taken kratom tea in early pregnancy, keep a record of the amount and discuss it with your obstetric provider; they can monitor fetal development with standard ultrasound screening.

Second trimester (weeks 14–27)

At this stage, the fetus is growing rapidly. Studies on other opioids have shown associations with reduced birth weight and altered growth patterns, and kratom’s similar receptor activity raises comparable concerns. Maintaining optimal nutrition and avoiding substances that could limit appetite or cause gastrointestinal distress is especially important.

Third trimester (weeks 28–40)

In the final weeks, the fetal brain continues to mature, and the risk of withdrawal syndromes emerges. If a mother uses kratom regularly, the infant may be born dependent on the herb’s alkaloids, leading to NAS—characterized by tremors, feeding difficulties, and irritability after birth.

Breastfeeding

There is no reliable data on how much mitragynine passes into breast milk, but the FDA warns that many substances can be secreted and affect the infant. Because newborns have immature liver enzymes, any exposure may lead to unpredictable effects. The safest course is to avoid kratom while nursing.

Can kratom tea cause withdrawal symptoms in newborns?

Yes, there is a plausible risk. Neonatal Abstinence Syndrome (NAS) is documented with maternal use of opioids, and kratom’s primary alkaloids act on the same receptors. Though formal case series on kratom‑related NAS are limited, the FDA and ACOG caution that any opioid‑like substance taken during pregnancy can lead to withdrawal in the newborn. Symptoms may include high‑pitched crying, tremors, feeding problems, and hypertonicity. If a baby shows these signs, clinicians will assess for NAS and may need to provide supportive care or medication‑assisted weaning.

Are there any safe alternatives to kratom tea for pain or anxiety in pregnancy?

• Acetaminophen (Tylenol): Widely regarded as safe for occasional pain relief when used at recommended adult doses.
• Prenatal yoga: Gentle poses and breathing exercises improve circulation and reduce stress without medication.
• Warm compresses: Applying heat to sore muscles can ease discomfort safely.
• Magnesium supplements (doctor‑approved): May help with muscle cramps and mild anxiety when taken under supervision.
• Meditation: Mindfulness techniques have been shown to lower anxiety scores in pregnant cohorts.
• Deep breathing exercises: Simple diaphragmatic breathing can reduce tension and improve pain tolerance.
• Physical therapy: Tailored exercises address musculoskeletal pain without drug exposure.
• Chamomile tea (in moderation): Generally considered low‑risk for most pregnant people, but should be limited to 1–2 cups per day.

What is the recommended dosage of kratom tea for pregnant women?

There is no established safe dosage for kratom tea during pregnancy. The variability in leaf potency, preparation methods, and individual metabolism makes any fixed amount unreliable. Because the FDA has not approved kratom for any indication, and ACOG explicitly advises against its use, the best recommendation is to avoid it entirely. If you are currently using kratom, discuss a taper plan with your provider to minimize withdrawal risk.

Does kratom tea affect fetal development or birth weight?

Evidence from animal models suggests that high‑dose kratom exposure can reduce fetal weight and increase mortality, likely due to opioid‑like effects on growth pathways. Human data are limited to case reports, but the potential for similar outcomes cannot be ruled out. The NHS cites a possible association between kratom use and low birth weight, urging pregnant people to steer clear of the herb.

What are the concerns about kratom tea and breastfeeding?

The primary concern is the unknown amount of mitragynine that may be secreted into breast milk. Even low levels could affect a newborn’s developing nervous system, leading to sedation, irritability, or feeding difficulties. Because safer, well‑studied analgesics like acetaminophen are available, most lactation consultants and pediatric guidelines recommend avoiding kratom while nursing.

Safe dosage / amount / brands

Because kratom is an unregulated supplement, brands vary widely in alkaloid concentration, and some may be contaminated with heavy metals or other substances. No reputable brand has been deemed pregnancy‑safe by ACOG, the NHS, or the FDA. If you are seeking a safe approach for managing pain or anxiety, opt for products that have clear FDA approval (e.g., acetaminophen) or non‑pharmacologic methods listed above. Avoid all kratom teas, powders, capsules, and extracts until further research clarifies safety.

Side effects and risks

Even short‑term kratom use can produce side effects such as nausea, constipation, dizziness, and increased heart rate. More serious concerns include:

• Liver injury: Case reports link kratom to hepatitis and elevated liver enzymes.
• Dependence and withdrawal: Regular users can develop tolerance and experience withdrawal symptoms upon cessation.
• Cardiovascular effects: Elevated blood pressure and tachycardia have been documented.
• Potential for contamination: Unregulated products may contain heavy metals, microbes, or adulterants.

While many of these effects are “annoying but not dangerous,” the combination of maternal health risks and unknown fetal impacts makes kratom a poor choice during pregnancy. If you experience severe nausea, jaundice (yellowing of skin or eyes), rapid heart rate, or any signs of withdrawal after stopping, contact your obstetric provider promptly.

Safer alternatives

1. Acetaminophen (Tylenol) – proven safe for occasional pain when used at recommended doses.
2. Prenatal yoga – gentle movement and breathing reduce stress without medication.
3. Warm compresses – effective for muscle soreness and menstrual‑like cramps.

Myth vs. fact

Myth: “Kratom is a natural herb, so it must be safe for pregnancy.”

Fact: Natural does not equal safe. Kratom’s active alkaloids act on opioid receptors, and there is no evidence establishing a safe threshold for pregnant people.

Myth: “A small cup of kratom tea won’t affect my baby.”

Fact: Even low‑dose exposure can cross the placenta; because fetal metabolism is immature, any amount may have unpredictable effects.

Myth: “If I stop drinking kratom now, the risk disappears.”

Fact: While cessation reduces ongoing exposure, any prior use should be discussed with a provider to monitor the pregnancy and plan for possible neonatal withdrawal.
