It is 2 a.m. Your mind is rehearsing tomorrow's conversation for the fifteenth time. You search for something that might help and find a wall of capsules, each one promising calm. It is hard to tell what has evidence behind it, what might interact with medication, or whether a supplement is even the help you need.
I understand the appeal of a clear answer you can put in a basket. I also think you deserve an honest answer before you spend money.
First, what do you mean by “anxiety”?
For one person it is a tight chest before a presentation. For another, it is weeks of broken sleep, constant dread and avoiding ordinary things. Those experiences may need different kinds of support. A supplement cannot tell you why you feel this way, and it cannot replace an assessment if symptoms are persistent, intense or new.
In counselling, we can look at the pattern around the feeling: when it arrives, what you fear might happen, what you do to get through the moment, and whether sleep, work or relationships are adding to the load. If you are concerned about a medical cause, speak to a doctor too. Anxiety counselling can be one part of that wider support.
What does the evidence say about supplements for anxiety?

There is no supplement I can responsibly recommend as a reliable answer for everyone. Research on many popular ingredients is still small, inconsistent or specific to particular preparations. “Natural” also says nothing about whether a product is safe alongside your medication.
Chamomile has shown some promise in small studies, but the findings are preliminary. Some studies of an oral lavender oil preparation have also reported benefits, although they do not settle the question for every lavender product. Ashwagandha has been studied for stress and sleep, but it can interact with medicines and has been linked, rarely, to liver injury. Kava is a particularly poor casual purchase because of the risk of serious liver harm.
Magnesium matters for normal body function, and correcting a low intake may be sensible. That is a different claim from saying magnesium will resolve anxiety. If you have kidney disease, take regular medication, are pregnant or are considering several products together, check with a pharmacist or doctor before adding anything.
How I would decide whether to buy something

I would start with three questions: What specific concern am I trying to address? What exactly is in this product, and how much? Who can check whether it is safe for me? If the label blends six herbs into a “calming complex” without useful amounts, it is harder to make an informed choice.
Our Brain & Mood range includes products people sometimes ask about when they are feeling stressed. A product's presence in the store is not a claim that it will resolve anxiety. Read its label, consider its ingredients and ask a qualified healthcare professional about your own circumstances.
The answer may include more than one kind of help

You can care about food, sleep and everyday wellbeing and still need a place to speak honestly about what has been weighing on you. Sometimes the most useful first step is a conversation about the fear behind the late-night search. Sometimes it is a medical appointment. You are allowed to seek both.
