Natural supplements and management for stress

[SleeplessinEastSussex]

I am looking for some natural supplements and ways to help deal with stress and anxiety.
Currently I walk an hour a day and reduced caffeine as per drs recommendation but wondered if there was anything else.

What triggers the stress and anxiety? Eg is it work related?

5 hpt has worked for me previously.. Though not every time. But worth a try maybe? You can get it in holland and barratt
