Mental health issues are now thought to affect one in six people in the UK, and to cost the economy a staggering £105 billion per year1. In order to raise public awareness of this growing problem and to help de-stigmatise mental health issues, the ‘Mental Health Foundation’ designate one week each year in May as ‘Mental Health Awareness Week’. This year the theme for the awareness week is anxiety, and between 12-18th May there will be many local events taking place throughout the UK to highlight the effects of this condition on sufferers and their families.
So, with mental health at the forefront of our thoughts this week, we thought it timely to take a look at ‘psychobiotics’. What does this newly conceived term actually mean? And, does it represent a significant scientific breakthrough, or is it simply a ‘re-naming’ of existing knowledge?
According to the 'Society of Biological Psychiatry' the term ‘psychobiotics’ is defined as a ‘live organism that, when ingested in adequate amounts, produces a health benefit in patients suffering from psychiatric illness’. It is thought that these probiotic bacteria species exert their beneficial effects on mental health and mood via a number of different pathways. According to Professor Selhub and colleagues2 at Harvard Medical School, psychobiotics:
So, unlike most allopathic medical treatments, these beneficial bacteria strains have many different ‘modes of action’, rather than just one. They impact our mood and mental well-being in a number of different ways, giving them huge potential as a therapeutic tool in the treatment of mental health disorders.
New evidence is emerging all the time to back up the claims that ‘psychobiotics’ may represent a significant breakthrough in the field of nutritional-psychiatry. Update: a recent study has linked specific probiotic strains to anxiety.
So, whether ‘Psychobiotics’ are a new scientific phenomena, or just a sexy new name for probiotics, and more specifically the influence they exert on the ‘gut-brain axis’ , shall be left to debate, but either way, the fact that they are now such a hot topic, can only be a good thing for future research and development. We think that the science behind ‘psychobiotics’ is here to stay. Whether the new name will stick remains to be seen, but we are excited about the increasing focus on the role of probiotics in supporting those with mental health disorders.
We are always excited by new research in to the role of the microbiome, and the myriad of ways that it impacts our health. We are so passionate about probiotics, that we dedicate all of our time and energy to them. Probiotics is all we do! Stay tuned for more research into this fascinating subject area.
