Natural Remedies for Stress and Anxiety: What a Pharmacist Recommends

Stress vs Anxiety: What's the Difference?

Stress is a response to an external pressure — work deadlines, financial worries, relationship difficulties. Remove the stressor, and the stress typically reduces.

Anxiety is a persistent feeling of worry or unease that may not have an obvious external cause. It can become a chronic condition that affects daily functioning.

Both are incredibly common. The Mental Health Foundation reports that 74% of UK adults have felt so stressed at some point in the past year that they felt overwhelmed or unable to cope.

While natural remedies can help manage mild to moderate stress and anxiety, they're not a substitute for professional help when symptoms are severe.

Evidence-Based Natural Remedies

1. Valerian Root (Kalms)

The evidence: Multiple clinical trials support valerian for reducing anxiety and improving sleep. A 2020 systematic review found it significantly reduced anxiety compared to placebo.

How it works: Valerian increases gamma-aminobutyric acid (GABA) levels in the brain — the same neurotransmitter targeted by prescription anti-anxiety medications like diazepam, but in a much gentler way.

Products:

• Kalms Day — daytime formula that relieves irritability and mild anxiety without causing drowsiness
• Kalms Night — higher dose for stress-related sleep difficulties

How to take: Consistently for at least 2-4 weeks. Valerian builds up in your system — it's not a one-dose fix.

2. Bach Rescue Remedy

The evidence: While the clinical evidence for Bach flower remedies is limited, Rescue Remedy has been used since the 1930s and many people report genuine benefit for acute moments of stress and anxiety.

How it works: Contains five flower essences intended to address specific emotional states: panic, impatience, fear, shock, and distraction.

Available as:

• Rescue Remedy pastilles (blackcurrant or orange flavour) — discreet, easy to carry
• Rescue Remedy drops — placed under the tongue
• Rescue Night — formulated for bedtime use

Best for: Situational anxiety — before exams, presentations, flights, dental appointments.

3. Magnesium

The evidence: Strong. A 2017 systematic review found that magnesium supplementation significantly reduced subjective anxiety. Many UK adults are mildly deficient.

How it works: Magnesium regulates the HPA axis (your stress response system), supports GABA function, and helps relax muscles. Low magnesium is associated with increased stress hormones.

Best form: Magnesium glycinate or citrate (better absorbed than oxide)

Dose: 200-400mg daily, preferably in the evening.

4. B Vitamins

The evidence: B vitamins (particularly B6, B9, and B12) are essential for neurotransmitter production including serotonin and dopamine. Deficiency is linked to increased anxiety and low mood.

Berocca provides a full B-vitamin complex along with vitamin C and is a popular daily supplement for people under stress.

5. Omega-3 Fatty Acids

The evidence: A 2018 meta-analysis found omega-3 supplementation (particularly at doses of 2,000mg+ EPA) significantly reduced anxiety symptoms.

How it works: Omega-3s reduce inflammation, which is increasingly linked to anxiety and depression. They also support brain cell membrane function.

Lifestyle Strategies (Free and Effective)

Exercise

The single most effective natural anxiety treatment. A 30-minute walk produces measurable reductions in anxiety hormones. Regular exercise is as effective as medication for mild to moderate anxiety in some studies.

The minimum effective dose: 150 minutes of moderate exercise per week (e.g., 30 minutes, 5 days a week).

Breathing Techniques

When anxiety strikes, your breathing becomes shallow and rapid. Deliberately slowing it down activates the parasympathetic nervous system:

Box breathing:

1. Breathe in for 4 seconds
2. Hold for 4 seconds
3. Breathe out for 4 seconds
4. Hold for 4 seconds
5. Repeat 4-6 times

Reducing Caffeine

Caffeine directly stimulates your stress response. If you're anxious, try cutting to one coffee before noon and switching to herbal tea in the afternoon. Many people notice a significant reduction in baseline anxiety within a week.

Journaling

Writing down your worries for 10-15 minutes before bed has been shown to reduce anxiety and improve sleep. It externalises the thoughts that otherwise loop in your head.

Social Connection

Isolation amplifies anxiety. Even brief social interaction — a phone call, a coffee with a friend — reduces cortisol and increases oxytocin.

What Doesn't Help

• Alcohol — provides temporary relief but increases baseline anxiety (rebound effect)
• Avoidance — avoiding anxiety triggers reinforces them, making anxiety worse long-term
• Excessive reassurance-seeking — checking and re-checking reduces anxiety momentarily but feeds the cycle
• Social media doom-scrolling — associated with increased anxiety in multiple studies

When to Seek Professional Help

Natural remedies work well for mild to moderate stress and anxiety. Seek professional help if:

• Anxiety is preventing you from working, socialising, or sleeping
• You experience panic attacks (sudden intense fear with physical symptoms)
• You're using alcohol or drugs to cope
• You have persistent physical symptoms (chest pain, heart palpitations, digestive problems)
• Anxiety has lasted more than 2 weeks with no improvement
• You're having thoughts of self-harm

Your GP can offer:

• CBT (Cognitive Behavioural Therapy) — available on the NHS via self-referral to IAPT
• Counselling — talking therapy
• Medication — SSRIs if needed (these are effective and well-tolerated)

In crisis: Contact Samaritans (116 123), text SHOUT to 85258, or call 999 if you're in immediate danger.

Building a Stress-Management Toolkit

A practical daily approach:

1. Morning: Berocca or B-vitamin supplement + exercise (even 20 minutes)
2. Daytime: Kalms Day if needed + breathing techniques for acute moments
3. Evening: Magnesium supplement + wind-down routine + journaling
4. Acute situations: Rescue Remedy pastilles
