Frequently Asked Questions
What are stress and mood supplements?
They're nutrients, amino acids and botanicals that support a healthy nervous system and help your mind and body cope with life's pressures - not sedatives or medicines. Our range spans traditional adaptogens like KSM-66® Ashwagandha, calming amino acids such as L-theanine, and foundation nutrients like magnesium and the B vitamins, which contribute to normal psychological function.
What are stress supplements good for?
They keep the systems that handle pressure properly nourished. Magnesium contributes to normal functioning of the nervous system and normal psychological function, the B vitamins help reduce tiredness and fatigue (stress is exhausting), and vitamin C supports the immune system, which busy, stressful periods can test. Botanicals like ashwagandha are taken to support relaxation and mental and physical wellbeing alongside these foundations.
Which stress supplement is right for me?
Match it to how stress shows up for you. If you feel wired and can't switch off, L-theanine may promote calm without drowsiness - ideal for daytime use. For ongoing pressure, KSM-66® Ashwagandha is the classic adaptogen, with added B vitamins, C and zinc. If stress is wrecking your sleep, 5-HTP and magnesium are the popular pairing - explore our full sleep range for more.
What is ashwagandha and how does it help with stress?
Ashwagandha is one of the most celebrated herbs in traditional Ayurvedic use, taken for generations to support the body through periods of pressure. Ours uses KSM-66®, the gold-standard branded root extract, enriched with vitamins B6 and B12 to help reduce tiredness and fatigue, plus vitamin C and zinc for immune support - all in a vegetarian and vegan-friendly capsule.
Can supplements help with anxiety?
We'll be straight with you: supplements support normal psychological function - they don't treat anxiety, and anything claiming to deserves scepticism. Nutrients like magnesium and B vitamins keep your nervous system properly nourished, and many people find botanicals like ashwagandha and L-theanine a helpful part of a calming routine. If anxiety is affecting your daily life, please speak to your GP - real help is available.
What's the difference between L-theanine and 5-HTP?
They work at different ends of the day. L-theanine - an amino acid found in tea leaves - may promote calm without drowsiness, making it the daytime choice for staying composed under pressure. 5-HTP is the body's natural precursor to serotonin and is our most popular evening option. The two are commonly taken alongside each other; if you take antidepressants, check with your GP before using 5-HTP.
Does magnesium help with stress?
Magnesium is quietly central to how you handle pressure - it contributes to normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue. Modern diets often run short, and stress itself makes demands on your reserves. Our dual-source Magnesium 188mg is formulated for optimal absorption in one daily tablet.
When should I take stress supplements?
It depends on the supplement. L-theanine suits the daytime, when you want calm focus; ashwagandha is typically taken daily with food, morning or evening, as its benefits build with consistent use; and 5-HTP and magnesium are best in the evening as part of a wind-down routine. Whichever you choose, they work best alongside the basics - sleep, movement, and time away from screens.
Are stress supplements habit forming?
No - our range is built on nutrients, amino acids and traditional botanicals rather than sedative medicines, and none are associated with the dependence linked to prescription treatments. They support your body's own systems rather than overriding them. That said, if stress or low mood has been weighing on you for weeks, a conversation with your GP is worth far more than any supplement.
