Herbal Supplements for Stress and Anxiety Relief
There’s a version of stress that feels manageable — a deadline, a hard conversation, a busy week. And then there’s the kind that seems to follow you everywhere: the low-grade hum of anxiety that doesn’t have a clear source, the tension you carry in your shoulders without realizing it, the way your mind won’t fully quiet down even when life is objectively fine.
That second kind tends to get worse after 40. Hormonal changes, shifting sleep patterns, and years of accumulated stress all play a role. I know because I’ve experienced it myself — and because I’ve spent a lot of time researching what actually helps, beyond the usual advice to “just meditate more.”
Herbal supplements are one piece of that puzzle. Not a magic fix — I’ll be honest about that upfront — but genuinely useful tools when you choose the right ones. My co-author Ginger brings both her medical assistant background and years of hands-on experience growing medicinal herbs professionally. Between the two of us, we’ve covered the research and the real-world side of what these plants actually do.
Here’s what’s worth your attention.
Your stress response is governed largely by cortisol — a hormone your adrenal glands release when you’re under pressure. In younger years, cortisol spikes quickly and then drops back down. As we age, that recovery becomes less efficient. Cortisol can stay elevated longer, and chronically high cortisol affects everything: sleep quality, mood, immune function, even belly fat accumulation.
At the same time, the brain’s primary calming system — GABA (gamma-aminobutyric acid) — becomes less responsive with age. GABA is the neurotransmitter that tells your nervous system to stand down. When it’s not working well, everything feels a little more “volume up” than it should.
The herbs I’m going to walk you through work on both of these systems — either by supporting cortisol regulation, enhancing GABA activity, or both.
If I had to choose one herb for stress in midlife, it would be ashwagandha. This Ayurvedic adaptogen has more clinical research behind it than almost any other stress herb, and the results are consistent: it measurably lowers cortisol levels and reduces self-reported stress and anxiety in human trials.
What makes it particularly relevant for adults 40+ is that it doesn’t just calm you down acutely — it helps recalibrate your stress response over time. Regular use appears to help the HPA axis (the system that controls cortisol release) become more appropriately regulated.
What to look for: A standardized extract — KSM-66 and Shoden are the two most studied forms. Both are root-only extracts standardized for withanolide content, which are the active compounds. Avoid generic ashwagandha powder with no standardization — potency varies wildly.
Typical dose: 300–600 mg daily. Works best taken consistently over several weeks rather than as a one-time dose.
Important note: Avoid ashwagandha if you have autoimmune conditions, thyroid disorders, or are pregnant. It can interact with thyroid medications and immunosuppressants.
My recommendation: Thorne Ashwagandha uses the Shoden extract — one of the most concentrated and clinically studied forms available. It’s third-party certified, which matters to me in a poorly regulated industry. → Check Thorne Ashwagandha on Amazon
Valerian root has been used for anxiety and sleep for centuries, and the mechanism is well understood: it appears to support GABA activity in the brain, promoting calm without the sedative effects of prescription medications.
I find valerian most useful in the evenings, when stress has a tendency to convert into that wired, can’t-unwind feeling that makes sleep difficult. It’s not dramatic — you won’t feel knocked out — but many people notice a quieter mental state and an easier time winding down.
Typical dose: 300–600 mg in the evening, about an hour before bed.
Worth knowing: Valerian has a strong, earthy smell that some people find unpleasant. Capsules take care of this. Also, a small percentage of people paradoxically feel more alert on valerian — if that’s you, discontinue and try a different herb.
Lemon balm (Melissa officinalis) is one of Ginger’s favorites — she grows it at the garden center and uses it in tea regularly. It’s a mild nervine, meaning it calms the nervous system without sedation, and it’s gentle enough to use during the day without affecting alertness.
Research shows lemon balm can reduce anxiety and improve mood, and it combines particularly well with valerian. It’s also easy to grow yourself if you’re interested in a fresh tea option.
Typical dose: 300–600 mg as a supplement, or 1–2 cups of strong tea made from fresh or dried leaf.
Chamomile is the most accessible of the stress herbs — most people have it in their kitchen already. Its active compound, apigenin, binds to the same GABA receptors that anti-anxiety medications target, just much more gently.
It’s best used as a daily ritual rather than an acute remedy. A cup of chamomile tea in the evening, consistently, can have a meaningful cumulative effect on overall tension and sleep quality.
One note: If you have a ragweed allergy, chamomile is in the same botanical family and may cause a reaction. Discontinue if you notice any sensitivity.
For ashwagandha specifically — which I consider the cornerstone stress herb for adults 40+ — here are the two I trust:
Thorne is a brand I trust across the board — they’re one of the few supplement companies that takes third-party testing seriously. Their ashwagandha uses Shoden extract, which is standardized to 35% withanolides — significantly higher potency than most products on the market. One capsule daily is all you need.

Nature Made is one of the most trusted mass-market supplement brands, and their KSM-66 ashwagandha delivers solid quality at a price that’s hard to beat. KSM-66 is the most extensively researched ashwagandha extract, with over 70 clinical studies behind it. If you’re just starting out, this is a great place to begin.

Herbal supplements for stress work gradually — they’re recalibrating your nervous system over time, not delivering an acute drug effect. Most people notice meaningful changes after 2–4 weeks of consistent use. What that tends to look like:
If you’ve noticed that stress is affecting your sleep specifically, there’s a lot of overlap in what helps. I cover the connection — and the full toolkit I use — in my complete guide to natural sleep solutions.
Herbs aren’t a substitute for addressing the root causes of chronic stress. Sleep deprivation, overcommitment, poor nutrition, lack of movement — none of those get fixed by a supplement. But for many people, the right herbal support can meaningfully lower the baseline, making it easier to do the other work.
Start with ashwagandha if you’re looking for one thing to try. Add valerian or lemon balm in the evenings if sleep is part of the picture. Give it four weeks of consistent use before evaluating.
As always, if you’re on medications or have any underlying health conditions — particularly thyroid or autoimmune — loop in your doctor before adding adaptogens. Most of these herbs are very safe for healthy adults, but herb-drug interactions are real and worth checking.
