Dr Aisling Dwyer
MB BCh BAO (Medicine, Surgery and Obstetrics), MSc (Personalised Nutrition)
Aisling worked at Optibac from 2018 to 2022.
Aisling has a degree in Medicine, Surgery & Obstetrics, and a Master's in Personalised Nutrition from CNELM. Her dissertation focused on the effects of the gastrointestinal microbiome on colonic motility, with a specific emphasis on the role of probiotics.
Her writing has been featured online on Netdoctor, Yahoo and The Daily Struggle. She is particularly interested in a holistic approach to health, with a focus on optimising wellbeing and quality of life.
Read Aisling’s favourite piece by searching our site for 'Probiotics for Acne & Skin Health'. She likes the article because it’s so topical given the rise of ‘maskne’ and highlights how our gut health is central to our overall health, including seemingly distant areas like our skin.
