	Description:		In this episode I’m diving into one small but powerful blood marker you’ve probably never been offered at the GP: homocysteine. We look at: What homocysteine actually is and why it matters for your mood, memory and hormones How B6, B12 and folate can help lower homocysteine The Oxford VITACOG trial showing B-vitamins can slow brain shrinkage in people with mild cognitive impairment Follow-up research showing B-vitamins work best when omega-3 levels are good – why your brain needs both B-vitamins and omega-3s together Practical ways to support healthy homocysteine levels through food, supplements and testing Studies mentioned in this episode: Smith AD et al. Homocysteine-Lowering by B Vitamins Slows the Rate of Accelerated Brain Atrophy in Mild Cognitive Impairment (PLoS ONE, 2010): https://pubmed.ncbi.nlm.nih.gov/20838622/ PubMed Oulhaj A et al.
