MUDWTR Rest Review 2026

What Is MUD\WTR Rest?

MUD\WTR :rest takes the brand's functional mushroom philosophy and applies it to the other end of the day. While the :rise products are about morning energy and focus, :rest is about evening relaxation and restorative sleep. It is the nightcap for people who do not want to take melatonin pills but want something more effective than a cup of chamomile tea.

The formula combines Turkey Tail and Reishi mushrooms with a lineup of well-studied sleep adaptogens: valerian root, passionflower, ashwagandha, and chamomile. All of this comes in a warm rooibos chai base with the familiar MUD\WTR spice blend. Zero caffeine, zero melatonin, zero grogginess the next morning.

The pitch is compelling, but the question everyone asks is: does it actually work? After several weeks of testing, here is our honest assessment.

Ingredients Breakdown

Sleep Adaptogens

The sleep support in MUD\WTR Rest comes from four ingredients, each with a different mechanism of action:

• Valerian Root Extract: One of the most well-studied natural sleep aids. Multiple clinical trials have examined valerian's ability to reduce the time it takes to fall asleep and improve overall sleep quality. It works by increasing gamma-aminobutyric acid (GABA) levels in the brain, promoting relaxation.
• Passionflower Extract: Used in traditional medicine for centuries as a calming herb. Research suggests it may increase GABA production, similar to valerian but through a different pathway. Studies have shown improvements in subjective sleep quality among participants who consumed passionflower tea before bed.
• Ashwagandha Root Extract: A powerful adaptogen with research backing its ability to reduce cortisol levels and alleviate stress. Since stress and elevated cortisol are among the most common causes of poor sleep, ashwagandha addresses sleep problems at their root cause rather than just treating the symptoms.
• Chamomile Extract: The classic bedtime tea ingredient. Chamomile contains apigenin, a flavonoid that binds to benzodiazepine receptors in the brain, promoting mild sedation and relaxation. It has been used for thousands of years across cultures as a calming herb.

What makes this combination effective is that it targets multiple pathways to relaxation: GABA enhancement (valerian and passionflower), cortisol reduction (ashwagandha), and mild sedation (chamomile). Rather than relying on a single mechanism like melatonin supplements do, MUD\WTR Rest takes a broader approach to supporting your body's natural wind-down process.

Mushroom Blend (1,200mg+)

MUD\WTR Rest uses a different mushroom blend than the morning products. Instead of the four-mushroom lineup (Lion's Mane, Chaga, Cordyceps, Reishi), Rest focuses on two species chosen specifically for evening use:

• Turkey Tail: One of the most extensively researched medicinal mushrooms, with over 400 published studies. Turkey Tail is particularly valued for gut health and immune support. It contains prebiotic fibers that feed beneficial gut bacteria, and its polysaccharopeptides (PSP and PSK) have been studied for immune-modulating properties. Gut health is increasingly linked to sleep quality through the gut-brain axis, making Turkey Tail a thoughtful inclusion in a sleep product.
• Reishi: Known as the "mushroom of immortality" in traditional Chinese medicine, Reishi has been used for thousands of years to promote calm and restful sleep. Modern research suggests Reishi may influence the sleep cycle by modulating certain neurotransmitters and reducing the time to fall asleep.

Rooibos Chai Base

The drink base is organic rooibos tea extract — a naturally caffeine-free South African tea with a slightly sweet, honeyed flavor. This is paired with the familiar MUD\WTR spice blend: turmeric, cinnamon, ginger, cardamom, black pepper, nutmeg, and cloves. Lucuma fruit powder adds subtle natural sweetness.

Taste and Preparation

MUD\WTR Rest has a warm, soothing rooibos chai flavor. It is gentler and less intense than the morning blends. The dominant notes are cinnamon and rooibos, with the herbal adaptogens adding a slightly earthy, botanical quality that we found pleasant and calming. There is no bitterness or harshness.

Preparation is the standard MUD\WTR process: one tablespoon in 8-12 ounces of hot water, stir or froth. For a bedtime drink, we found that preparing it with warm milk (oat milk worked especially well) made it feel more like a ritual — something that signals to your body and mind that it is time to wind down. A touch of honey complements the spices beautifully.

The act of preparing and slowly sipping a warm drink before bed is itself a form of sleep hygiene. It gives you something to do that does not involve screens, and the warmth promotes physical relaxation. MUD\WTR Rest turns this into something more than just a warm drink by adding functional ingredients that actively support sleep.

Does It Actually Work?

Here is the honest answer: it depends on your expectations and your patience.

If you are expecting MUD\WTR Rest to knock you out like a melatonin supplement or a sleeping pill, you will be disappointed. That is not what it does, and that is not what it is designed to do. There is no instant drowsiness, no heavy-eyelid feeling 30 minutes after drinking it.

What our testers experienced over two to three weeks of consistent use was subtler but meaningful: an easier time transitioning from "awake mode" to "sleep mode" in the evening, fewer racing thoughts at bedtime, and — for several team members — noticeably better sleep quality as measured by wearable sleep trackers. Wake-ups during the night decreased, and morning freshness improved.

The key word is consistent. Adaptogens like ashwagandha and Reishi build their effects over time. If you try MUD\WTR Rest once and judge it, you are not giving the ingredients a fair chance. Commit to two to three weeks of nightly use before deciding whether it works for you.

The other factor is your existing sleep hygiene. MUD\WTR Rest will not overcome scrolling social media until midnight or drinking coffee at 4 PM. It works best as part of an overall wind-down routine: dim lights, put away screens, prepare your Rest, and allow your body to transition naturally into sleep readiness.

Who Is MUD\WTR Rest For?

• People who struggle to "turn off" at night: If your mind races at bedtime or you have trouble transitioning from activity to sleep, the adaptogen blend targets exactly this problem.
• Melatonin-averse individuals: If melatonin makes you groggy, gives you vivid dreams, or you prefer not to supplement a hormone your body produces naturally, Rest offers a non-hormonal alternative.
• MUD\WTR fans wanting an evening option: If you drink :rise in the morning, :rest completes the daily mushroom routine. Morning energy, evening recovery.
• People interested in gut health: The Turkey Tail mushroom provides prebiotic and immune benefits that complement the sleep support.

MUD\WTR Rest is probably not the best fit if you need immediate, powerful sleep assistance (talk to your doctor about clinical sleep issues), if you dislike herbal or chai flavors, or if you are looking for the highest mushroom dose (the morning blends offer more).

Our Verdict

We give MUD\WTR :rest a 4.3 out of 5. It is the lowest-rated product in the MUD\WTR lineup in our testing, but that says more about how strong the rest of the lineup is than about any shortcoming with Rest itself. A 4.3 is still an excellent score.

The adaptogen blend is thoughtfully formulated and science-backed. The flavor is warm and soothing. The absence of melatonin is a genuine advantage for people who want natural sleep support without hormonal supplementation. And the Turkey Tail mushroom adds immune and gut benefits that you do not find in most sleep products.

The main limitation is patience: you need to use it consistently for weeks before the full effects emerge. If you can commit to that, MUD\WTR Rest is a worthy addition to your evening routine.
