Most people have heard of St John's Wort and omega-3s. But did you know there are a lot more over-the-counter herbal products and supplements out there targeting depression? In our review of clinical trials of these products, we found 64 different over-the-counter (OTC) products that have been evaluated for depression - but with differing levels of evidence for each.
Why look at this topic?
Depression is increasingly common, to the extent that it is sometimes described as an epidemic. In the UK, 11.3% of people report mild depressive symptoms, 4.2% moderate depressive symptoms, and 3.3% severe depressive symptoms. Many of us know someone who struggles with minor or moderate levels of depression, or we may struggle from depressive symptoms ourselves. Often, we will try many things to help, such as antidepressants, talking therapies, meditation, or exercise. One common treatment people try is OTC products which are widely available and accessible from supermarkets, pharmacies, health food shops, and online.
Once you start looking into which OTC product might be helpful, the list becomes endless. This is particularly the case if you read online blogs or look at social media promotion of various products. How do we know what is evidence-based? What products are effective? Are they safe?
