Interest in collagen supplements continues to grow – and for good reason. That’s because despite rubbish claims that are way off the mark that there is ‘no evidence they work’ and ‘all the research is funded by the collagen industry’, the reality is very different. In past podcasts I’ve delved into the topic of hydrolysed collagen supplements and skin health and where there are now dozens of blinded randomised controlled trials showing a benefit in increasing skin moisture and elasticity and reducing wrinkles – with many of the studies free from any conflict of interest and all supported by plausible mechanisms as to why collagen, and not other protein sources, can do this. But for this podcast, I want to focus on one of the other reasons that people may take collagen: and that’s to give relief from joint pain and stiffness. So for this episode, I’m going to focus on arthritis and outline what the clinical evidence says and what unique biological mechanisms could be at play to support a unique effect of collagen supplements.

Irritable bowel syndrome is one of the most common gastrointestinal complaints. With no single identified trigger or treatment, IBS can be a minefield for a person to try and get on top of. Dietary changes like a low-FODMAP diet, supplements and stress modification all have a role to play. Another emerging treatment for IBS are probiotics. Probiotics may improve IBS symptoms by changing the gut microbiota and their metabolite production which can change gut motility, inflammation and gut hypersensitivity. In this podcast, I’ll look at the evidence for the use of probiotic supplements in IBS.

The establishment and development of the microbiome in the early stages of life can play a pivotal role in affecting our health throughout life. The formation of our microbiome happens during the perinatal period where it is influenced by the interaction between the microbiomes of mothers and infants. The microbial composition of breast milk plays an important part in this process. The microbiome of breast milk is also influenced by the gut microbiome of the mother through what is termed the gut-breast axis. In this podcast, I'll explore these mother-infant microbiome links and discover what the scientific evidence has to say about the potential for maternal probiotic supplements having a positive influence on the health of mother and infant.
