Best Choices for Calming Drinks

From herbal teas and coffee substitutes to probiotic drinks, I recommend keeping a few calming drinks on hand to settle the mind and refocus on what matters. A good tea for anxiety and stress can be genuinely helpful — but a few beverages actively work against your mental health and sleep, which I’ll cover at the end.

1. Valerian Root Tea

Valerian root tea remains one of the most popular calming drinks, and for good reason. A review in the American Journal of Medicine of 16 studies and over 1,000 people found valerian root improved sleep quality without significant side effects. Since stress and anxiety are often the root cause of poor sleep, this dual action matters.

If you’re trying valerian for the first time, take it before bed — its sedating effect can be strong enough that you shouldn’t drive or operate machinery afterward. Many people do find they can sip it during the day without issue, but start cautiously.

From my own experience and clinical practice: valerian can absolutely be enjoyed during the day, but be prepared for what I’d describe as a warm, fuzzy feeling — for some people that’s pleasantly relaxing, but for others it feels a bit too strong or heavy-headed for a normal workday. There’s also a paradoxical effect worth knowing about: I’ve had a handful of clients over the years who get the opposite reaction from valerian and feel wired or energized by it instead of calm. It’s not common, but if valerian ever leaves you feeling more activated rather than relaxed, that’s a real, recognized response — not something wrong with you — and it simply means valerian isn’t the right calming drink for your body.

Tip: Steep 1 teaspoon dried valerian root in a tea ball for 10–15 minutes. Add honey if desired.

2. Sauerkraut Juice

Sauerkraut juice (sauerkraut kvass) has calming effects that surprise most people, and raw sauerkraut’s health benefits extend well beyond digestion.

As a natural probiotic source, raw sauerkraut delivers live bacteria that support gut health — and a healthy gut sends calming signals throughout the body via the gut-brain axis. Research consistently supports that specific probiotic strains reduce anxiety symptoms.

Tip: Start with just 2–4 ounces a day, mixed into vegetable juice or a smoothie if the taste is too strong on its own.

3. Mushroom “Coffee” Substitute

Mushroom coffee alternatives combine medicinal mushrooms like reishi and chaga with adaptogens such as ashwagandha — ingredients known to support gut and nerve health, which in turn calms the body. The gut is often called the “second brain” because it produces the majority of the body’s serotonin.

Many people find mushroom coffee gives calm, sustained energy and focus rather than the jittery spike of regular coffee.

In my practice, this is a workday staple: mushroom coffee substitutes are specifically about staying calm and focused during the day, not about winding down at night. Several of my clients rely on it as their go-to for getting through a demanding workday without the anxious, jittery edge regular coffee can bring — and I use it myself for the exact same reason. It’s one of the easiest swaps for anyone who wants steady focus at their desk without sacrificing calm.

Tip: Look specifically for mushroom coffee substitutes, not mushroom-coffee blends that still contain real coffee and meaningful caffeine.

4. Tulsi (Holy Basil) Tea

Tulsi (holy basil) is a basil relative central to Ayurvedic medicine, where it’s called “the elixir of life.” It’s classified as an adaptogen — a substance that helps the body normalize its stress response rather than simply sedating it.

The strongest evidence so far comes from an 8-week randomized, double-blind, placebo-controlled trial of a standardized holy basil extract, which found measurable reductions in stress and improved sleep quality in adults experiencing everyday stress. Researchers believe tulsi works by modulating the HPA axis (your body’s central stress-hormone pathway) and normalizing cortisol output — mechanisms I go into in depth in Cortisol Fix.

In my own practice: tulsi is one of the drinks I recommend most, and it’s not just the research — I notice it myself. On days I have a cup or two of tulsi tea, my whole day feels calmer and less reactive, and I hear the same thing constantly from clients: they describe fewer “spiky” moments of stress and an easier time letting small irritations roll off. It’s a simple, low-risk swap for people who want something gentler than reaching for a sedative or an extra glass of wine at the end of the day.

Tip: Steep dried tulsi leaves or a tea bag for 3–5 minutes. If tea isn’t your thing, tulsi is also available as a tulsi tincture or supplement.

5. Kombucha Tea

Kombucha delivers calming benefits from two directions: natural probiotics that support the gut-brain axis, and L-theanine carried over from the green or black tea base. Theanine is well studied for promoting relaxation without sedation, and newer 2025 research suggests theanine in brewed tea may also support steady alertness rather than drowsiness — a useful combination if you want calm and focus.

Tip: Kombucha typically has under 25 mg of caffeine per serving, but check the label. If you’re sensitive, choose ginger, lemon, or fruit-flavored kombucha and drink it earlier in the day.

6. Kava Root Tea

Kava has been used for thousands of years in South Pacific ceremonial drinks, and clinical trials going back to a 2003 Cochrane review have found it effective for anxiety compared to placebo.

2026 update: The safety picture is more nuanced than it used to be. A 2025 narrative systematic review in Drug and Alcohol Review confirmed kava reduces anxiety symptoms short-term, but flagged liver toxicity and cognitive-impairment risks with long-term or heavy use. Separately, some WHO-linked research has pushed back on how much of the historic liver-injury concern was tied to poor-quality extracts rather than kava itself. The safest approach: use traditional water-based root preparations (not alcohol- or acetone-based extracts), avoid daily long-term use, and skip it entirely if you have any liver condition or drink alcohol regularly.

Tip: Avoid any product containing kava leaves or stems — only the root is considered safe, and never combine kava with alcohol or sedative medications.

My own experience: kava tea genuinely has a buzzy, social quality to it that reminds me of alcohol — that loose, relaxed feeling — but with far less overall risk when used sensibly. I personally use it as a stand-in for the times I might otherwise reach for a drink, without the downsides that come with actual alcohol. That said, I still treat it with real caution: I drink it at home, not out and about, and I don’t make it a daily habit given the safety notes above.

7. Saffron Tea

New to this list for 2026: saffron has quietly become one of the best-evidenced calming ingredients on this page. A 2025 meta-analysis of randomized controlled trials found saffron produced anxiety and depression symptom reductions statistically comparable to SSRIs, with meaningfully fewer side effects. Researchers believe saffron’s crocin and safranal compounds influence serotonin reuptake, calm HPA-axis overactivation, and reduce inflammatory markers linked to low mood.

In my own clinical experience, saffron has helped countless clients move through sadness and improved their anxiety symptoms — it’s genuinely one of the supplements I recommend most often. I go into much more depth on the research and dosing in my posts on saffron’s fascinating benefits for mood and gut health and the best saffron supplements to look for, if you’d rather take it as a supplement than a tea.

Saffron tea is simple to make and pairs well with a splash of honey or lemon, and it’s one of the few options on this list with dosing data directly comparable to a prescription antidepressant class.

Tip: Steep 15–30 mg of saffron threads (roughly a large pinch) in hot water for 10 minutes. Most clinical trials used 30 mg/day of standardized extract, so treat tea as a gentler, food-based version of that dose.

8. Magnesium Calming Drinks

Magnesium powder drinks (like the “Calm” brand and similar magnesium citrate or glycinate powders) are popular for a reason: most Americans fall short on magnesium, and magnesium plays a direct role in GABA production and healthy cortisol regulation — a pathway I unpack more fully in Cortisol Fix.

2026 update — the evidence is more mixed than it used to be. Clinical trials using 200–400 mg of elemental magnesium daily (the amount used in most calming-drink formulas) show benefits for people who are magnesium-deficient to begin with. But some newer randomized trials in people with already-adequate magnesium levels found no measurable difference in anxiety scores versus placebo. The honest takeaway: magnesium calming drinks are most likely to help if you’re actually low in magnesium, which is common, but they’re not a guaranteed anxiety fix for everyone. For guidance on choosing the right form, see my full breakdown of the best magnesium supplement for sleep and calm — magnesium glycinate is generally the best-absorbed, most stomach-friendly option, while magnesium citrate can cause loose stools in some people.

Tip: Start with 100–200 mg of elemental magnesium and increase gradually. Splitting the dose morning and evening tends to work better than one large serving.

9. Tart Cherry Juice

Tart cherry juice is a natural source of melatonin and has real research behind it for sleep. Research in the European Journal of Nutrition found that people who drank cherry juice before bed slept an average of 85 minutes longer, with older adults seeing even greater improvements than younger adults, including favorable changes in sleep-promoting cytokines.

A separate study in the Journal of Medicinal Foods confirmed improved sleep duration and blood melatonin levels in older adults, and tart cherries may also support brain health, joint comfort, and kidney health thanks to their antioxidant load.

Tip: A typical serving of tart cherry concentrate is just 2 tablespoons (about 10g carbohydrate), mixed into water.

10. Chamomile Tea

Chamomile has been used for its calming effects since ancient Rome, and modern clinical trials back it up. In a trial published in Phytomedicine, 179 people with generalized anxiety disorder who took 1,500 mg/day of chamomile capsules (roughly equivalent to 3 cups of tea) saw significant reductions in anxiety symptoms compared to placebo. Other research links chamomile to reduced symptoms of depression as well, alongside general anti-inflammatory effects.

What I see in practice: chamomile is one of the two or three drinks I personally reach for most, and I’ve watched enough clients switch from nightly sleep medication to an evening cup of chamomile to trust it beyond the research alone. It’s simple, it’s inexpensive, and for most people it’s a far safer long-term habit than relying on a sleep aid or anti-anxiety medication night after night.

There’s also a longevity angle worth knowing about. Chamomile is one of the richest natural sources of apigenin, a flavonoid getting real attention in aging research for its ability to calm cellular inflammation (what researchers call the “senescence-associated secretory phenotype”) and support NAD+ levels. This is still early, mostly preclinical evidence — human trials on apigenin specifically for aging haven’t been done yet — but it’s a nice bonus reason to make chamomile a daily habit rather than an occasional one.

Tip: Sip chamomile tea throughout the day to take the edge off chronic stress — its effects tend to be felt quickly, which is part of why it remains a go-to.

11. Lavender Tea

Lavender has a long history as an anxiolytic (anxiety-reducing) herb, and research on lavender for anxiety continues to support its use as tea or aromatherapy. In one study of heart-surgery patients, lavender lowered cortisol levels by roughly 70%.

Tip: Lavender’s flavor is strong, so a small pinch of dried buds goes a long way — many people blend it with chamomile for a milder, rounder cup. Diffusing lavender essential oil is another effective route if tea isn’t for you.

A note on potency: lavender is one of the stronger calming herbs on this list, which is exactly why a small amount added to coffee can take the jittery edge off caffeine without fully sedating you. But that same potency means it doesn’t agree with everyone. I personally have a reactivity to lavender, something I only discovered after doing my own MRT food sensitivity testing. If a calming herb like lavender ever leaves you feeling worse rather than better, it’s worth considering whether an individual sensitivity, not the herb itself, is the real issue.

12. Passionflower Tea

Passionflower is traditionally used for insomnia, irritability, and nervous anxiety. Clinical research using passionflower tincture (15 drops, 3 times daily) as an add-on to antidepressants found it measurably reduced stress, and early evidence also points to improved sleep time.

Caution: Avoid passionflower if you’re pregnant or taking sedative medications, since its calming effect can be additive.

13. Sleepy Tea Blends

If you’re new to calming drinks, a blended sleepy tea is an easy place to start. Combination teas often deliver additive benefits over single-herb teas, and common blends include lemon balm, valerian, lavender, chamomile, rose hips, jasmine, rooibos, skullcap, licorice root, and kava root. Some blends also add theanine alongside valerian and chamomile for a fuller calming effect with less caffeine than green tea alone.

Note: Skullcap is safe for most healthy people but should be avoided with liver disease or if you’re taking cholesterol medications, blood thinners, or painkillers.

14. Fresh Garden Sage Iced Tea

One of my own favorite tricks, especially in summer: I grow sage in my garden here in Montana, and a big pitcher of fresh sage iced tea is one of the most relaxing rituals of my week. There’s something about sitting outside with a cold glass of it that helps me actually unwind and focus, rather than just powering through the day.

Sage is rich in antioxidant compounds like rosmarinic acid and carnosol, and has a long history of traditional use for calm and mental clarity — its genus name, Salvia, comes from the Latin for “to heal.” I cover the fuller research on its brain and inflammation benefits in my sage benefits post.

The best part is that sage is easy to grow and even easier to keep on hand. If you have a garden, sage is one of the simplest herbs to dry at home, which means you can enjoy sage tea year-round, not just in growing season.

Tip: For iced tea, steep a handful of fresh sage leaves in hot water for 5–10 minutes, then chill and pour over ice with a squeeze of lemon. For dried sage tea any time of year, hang small bundles of fresh sage upside down in a warm, dry spot out of direct sunlight for 1–2 weeks, then crumble the dried leaves into an airtight jar. Use about 1 teaspoon of dried sage per cup of hot water, steeped for 5 minutes.

Drinks to Avoid

A few popular drinks work against calm, sleep, and stress resilience — here’s what to know about each.

Warm Milk

Folklore says warm milk helps you sleep, but lactose can unsettle digestion for many adults, and dairy is a common heartburn trigger — both of which can leave you more restless, not less. Milk does supply tryptophan, a precursor to serotonin and melatonin, but you can get the same benefit more comfortably from turkey, pumpkin seeds, or aged cheese, which is naturally lower in lactose. If you still want a warm milk ritual, try heated coconut milk with a little honey and grated ginger instead.

Alcohol

Alcohol feels calming in the moment but increases anxiety over the following 24–48 hours by depleting nutrients and disrupting the gut microbiome. It’s also a well-documented trigger for gastroesophageal reflux, which further degrades sleep quality. Reach for a calming tea or mushroom coffee substitute instead.

Energy Drinks

Energy drinks may feel good briefly, but high caffeine, stimulants, sugar, and artificial additives tend to spike stress and anxiety later. Cap caffeine intake by 2pm, and if you want an energy boost without the crash, try a smoothie with chia seeds, berries, and leafy greens instead — all magnesium-rich and gut-supportive.

Frequently Asked Questions

What is the fastest-acting calming drink?

Chamomile tea and L-theanine-containing teas (green, black, or kombucha) tend to produce noticeable calming effects within 30–60 minutes for most people, since both act quickly on GABA and serotonin pathways. Kava can act even faster but carries more safety caveats for regular use.

Is kava safe to drink for anxiety?

Kava can reduce anxiety short-term, but a 2025 systematic review flagged liver toxicity and cognitive-impairment risks with long-term or heavy use. Choose traditional water-based root preparations, avoid daily long-term use, and skip it if you have liver disease or drink alcohol regularly.

Can magnesium drinks actually reduce anxiety?

Magnesium calming drinks are most effective for people who are actually magnesium-deficient, which is common. In people with adequate magnesium levels, some newer trials found no measurable anxiety benefit over placebo, so results vary by individual.

Is saffron really as effective as anti-anxiety medication?

A 2025 meta-analysis found saffron produced statistically comparable symptom reductions to SSRIs for anxiety and depression, with fewer side effects. It’s promising, but saffron shouldn’t replace a prescribed treatment plan without your provider’s input.

Can I drink calming teas while taking anti-anxiety medication?

Many herbal calming drinks, especially kava, passionflower, and valerian, can have additive sedative effects with prescription anti-anxiety medications or sleep aids. Always check with your prescriber before combining them.

What’s the difference between chamomile and passionflower tea for anxiety?

Chamomile has stronger, more consistent clinical trial support for generalized anxiety symptoms specifically. Passionflower has more evidence as an add-on to existing antidepressant treatment and for improving sleep onset. Both are considered gentle and low-risk for most healthy adults.

Are calming teas safer than sleep medication?

For most healthy adults, teas like chamomile and tulsi carry a much lower risk profile than prescription sleep medications, which can cause dependency, next-day grogginess, and withdrawal effects with long-term use. Herbal teas aren’t a replacement for medically necessary treatment, but many people find they can reduce or replace occasional reliance on sleep aids under a doctor’s guidance.

Summary

Before reaching for a cocktail or an energy drink to manage stress, try a healthier alternative. The best-evidenced options on this list are chamomile tea, saffron tea, tulsi, and L-theanine-rich teas — with magnesium and kava offering real benefits for the right person, once you understand the caveats.

For the best results, make these drinks a regular habit rather than a one-off; many of the benefits, especially with tulsi and magnesium, build over weeks. If chronic stress and cortisol dysregulation are the deeper pattern behind your anxiety or sleep struggles, Cortisol Fix was written to walk you through that full picture — relaxing, rebalancing, and genuinely getting well again, not just masking symptoms one cup at a time.
