Mud Water Side Effects: What You Need to Know Before You Drink It

MUD WTR side effects can include digestive changes, headaches during a coffee transition, and possible interactions with certain medications, mostly linked to its mushroom and botanical ingredients rather than the drink itself. Before switching from your morning coffee to this mushroom based alternative, it helps to know exactly what you’re introducing into your routine and who should think twice before trying it.

What Is MUD WTR and What’s In It?

MUD WTR is a powdered mushroom coffee alternative built around four adaptogenic mushrooms, chaga, reishi, lion’s mane, and cordyceps, combined with organic cacao, Masala chai spices, and a fraction of the caffeine found in regular coffee. The Original blend contains 2.24 grams of mushrooms and about 35 milligrams of caffeine per serving, roughly a third to half of what a typical cup of coffee delivers. The brand sells four distinct varieties, Original, Matcha, Turmeric, and Rest, each with a slightly different ingredient list and purpose, from morning energy to evening wind down.

What Are the Most Common Mud Water Side Effects?

The most frequently reported effects fall into a few categories: digestive changes, mild sedation from certain botanicals, and rare allergic reactions to specific ingredients like coconut. Because MUD WTR blends mushrooms with a wide range of spices and adaptogens, including turmeric, ginger, cardamom, nutmeg, and cloves, the ingredient list is considerably longer and more varied than a simple cup of coffee, which naturally increases the number of possible individual reactions. Travelers switching from coffee consistently find the lower caffeine content itself causes a noticeably different, calmer experience rather than a jittery one, though this same lower caffeine dose can trigger mild withdrawal symptoms like headaches or fatigue in heavy coffee drinkers during the first few days of transitioning.

Does MUD WTR Make You Poop?

For some people, yes, and it’s one of the more commonly reported unexpected effects. One documented week-long trial of drinking MUD WTR Original daily reported noticeably more frequent bathroom trips, describing a sensation of the drink moving through the digestive system shortly after finishing a cup. The likely explanation points to the combination of warming spices, cacao, and the fiber naturally present in whole mushroom powder, all of which can have a mild stimulating effect on digestion for some drinkers. This effect is generally considered mild and temporary rather than a sign of a problem, though anyone experiencing persistent or severe digestive discomfort should stop use and speak with a doctor.

Is MUD WTR Safe During Pregnancy or Breastfeeding?

No, MUD WTR is generally not recommended during pregnancy or while breastfeeding. Several botanical ingredients found across its four varieties, including turmeric, cardamom, ashwagandha, nutmeg, valerian root, passionflower, and chamomile, have been linked to potential preterm labor or miscarriage risk in some research. Turmeric appears in every single MUD WTR flavor, meaning this concern applies broadly across the entire product line rather than just one variety. Experts also note there simply isn’t enough research available yet to confirm whether the mushroom compounds themselves are safe for a developing baby or whether they pass into breast milk, so the cautious, research backed recommendation is to avoid MUD WTR entirely during pregnancy and breastfeeding unless a doctor says otherwise.

Can MUD WTR Interact With Medications?

Yes, and this is one of the more important safety considerations for anyone currently taking prescription medication.

Medication Type	Ingredients of Concern	Potential Effect
Anticoagulants (blood thinners)	Chaga, reishi, cordyceps	May affect blood clotting
Antidiabetic medications	Turmeric, ashwagandha	May further lower blood sugar
Antihypertensives (blood pressure meds)	Turmeric, ashwagandha, chamomile, reishi, lion’s mane, turkey tail	May cause blood pressure to drop too low
Sedatives (anticonvulsants, benzodiazepines, sleep medications)	Ashwagandha, valerian root, passionflower, chamomile	May increase sedating effects

These interaction risks aren’t limited to just one MUD WTR flavor since several of the ingredients involved, especially turmeric, appear across multiple varieties. A common mistake people make is assuming a natural, plant based ingredient can’t interact with medication the way a synthetic drug can, when in reality many of these botanicals have measurable effects on blood sugar, blood pressure, and clotting. Anyone managing diabetes, blood pressure, blood clotting conditions, or taking sedative medications should talk to a doctor before adding MUD WTR to their routine.

What Is the Prop 65 Warning on MUD WTR?

MUD WTR carries a California Proposition 65 warning stating the product can expose consumers to lead, a substance the state has identified as capable of causing cancer or reproductive harm. It’s worth understanding what this warning actually means in context: Prop 65 requires warnings for any product containing trace amounts of any of over 800 listed chemicals, and lead specifically is a naturally occurring, ubiquitous substance that shows up in trace levels across many everyday foods and beverages, not just MUD WTR. California is the only state that legally requires this kind of warning label, and the presence of a Prop 65 notice does not mean a product violates FDA safety standards, since MUD WTR states its products comply with all FDA requirements. Some competing mushroom coffee brands, like Four Sigmatic, carry the same warning, while others don’t, though the absence of a Prop 65 label on a competing product doesn’t necessarily mean it’s free of the same trace substances.

Does MUD WTR Have Caffeine?

Yes, though the amount varies significantly by variety, and two of the four flavors are entirely caffeine free.

Variety	Caffeine Content	Base
Original	35mg	Black tea
Matcha	55mg	Matcha
Turmeric	0mg	Rooibos
Rest	0mg	Rooibos

For comparison, a typical cup of brewed coffee contains somewhere around 95 to 200 milligrams of caffeine, meaning even MUD WTR’s most caffeinated option, Matcha, still delivers noticeably less than a standard cup. General research suggests up to 400 milligrams of caffeine daily is a reasonably safe range for most healthy adults, while pregnant individuals are often advised to stay closer to 200 milligrams or less, per guidance from their doctor. Locals switching gradually rather than quitting coffee cold turkey consistently report an easier transition, since dropping caffeine intake too quickly can trigger withdrawal headaches, irritability, and fatigue regardless of which lower-caffeine product you’re switching to.

Can MUD WTR Trigger a Coconut Allergy?

Yes, if you use the brand’s creamer or sweetener products alongside your mushroom coffee. Both the powdered creamer, made from coconut milk and MCT oil, and the coconut sugar based sweetener contain coconut, making them unsafe for anyone with a coconut allergy. The base mushroom coffee powders themselves don’t contain coconut, so someone with this allergy can still drink MUD WTR safely as long as they skip the branded creamer and sweetener and use a different milk or sugar alternative instead.

Will MUD WTR Make You Fail a Drug Test?

No, MUD WTR should not cause a failed drug test. The mushrooms used in the product, chaga, reishi, lion’s mane, cordyceps, and turkey tail, are functional mushrooms rather than psychoactive ones, and none of them contain psilocybin, psilocin, or any other controlled substance found in so-called “magic” mushrooms. This is a common point of confusion given how often mushrooms in general get associated with psychoactive effects, but the mushrooms in MUD WTR and similar mushroom coffee products serve a completely different, non-psychoactive purpose.

Is MUD WTR Safe for People With Diabetes or Blood Pressure Concerns?

It depends on the individual, and this is a case where checking with a doctor first genuinely matters. Several MUD WTR ingredients, including turmeric and ashwagandha, have been shown in research to lower blood sugar levels, which could be beneficial for some but risky for anyone already taking medication to manage diabetes, since the combined effect could push blood sugar too low. Similarly, turmeric, ashwagandha, chamomile, reishi, lion’s mane, and turkey tail have all been linked to blood pressure reduction, meaning anyone with naturally low blood pressure or taking blood pressure medication should approach MUD WTR cautiously. For people without these preexisting conditions, these same effects are generally considered a low risk, non-issue.

Which MUD WTR Variety Has the Fewest Side Effect Risks?

Turmeric and Original generally carry a somewhat narrower risk profile than Rest, since Rest is the only variety containing valerian root, passionflower, and added ashwagandha and chamomile extract, ingredients most closely tied to sedation and blood pressure effects. That said, turmeric itself appears in all four varieties and carries its own pregnancy and blood sugar considerations, so no single MUD WTR variety is entirely free of the ingredients flagged in this article. Anyone with a specific medical condition or medication concern should compare the full ingredient list of whichever variety they’re considering against their doctor’s guidance rather than assuming one flavor is automatically the safe choice.

Final Thoughts

Most people who try MUD WTR experience nothing more serious than mild digestive changes or an adjustment period while cutting back on caffeine. The real side effect risks concentrate in specific groups: anyone pregnant or breastfeeding, managing diabetes or blood pressure, taking sedative or blood thinning medications, or allergic to coconut. This article is for informational purposes only and isn’t a substitute for medical advice, so if any of those situations apply to you, talk to a doctor before adding MUD WTR or any mushroom coffee alternative to your routine.

FAQs

Is MUD WTR safe to drink every day?

For most healthy adults who aren’t pregnant, breastfeeding, or managing a condition affected by its ingredients, daily use is generally considered reasonable, though checking with a doctor before starting any new daily supplement is always a smart first step.

Can MUD WTR cause an allergic reaction?

Yes, though true allergic reactions appear to be uncommon; the most likely trigger is coconut in the optional creamer or sweetener, and anyone with a known mushroom or spice sensitivity should review the full ingredient list before trying it.

Does MUD WTR cause headaches?

Headaches are more commonly linked to reducing caffeine intake too quickly when switching from regular coffee rather than to MUD WTR itself, so a gradual transition tends to minimize this effect.

What should I do if I have a reaction to MUD WTR?

Stop drinking it and contact a healthcare provider, especially if symptoms are severe or persistent; MUD WTR’s own customer service can be slow to respond, so a doctor is the more reliable first call for any genuine health concern.
