In this episode of Mohivate, Dr Mohi Sarawgee explores berberine, one of the most talked about metabolic supplements right now, bringing clarity to a conversation often shaped more by social media than by science.
Berberine is a naturally occurring alkaloid with thousands of years of history in Ayurvedic and traditional Chinese medicine. This episode traces how it moved from gut medicine to metabolic science, unpacking the mechanisms behind its effects on blood sugar, insulin resistance, lipid metabolism, and the PCSK9 pathway, the same cholesterol target that billion dollar injectable medications were developed to address.
The episode examines the clinical evidence honestly, including the landmark head to head comparison with metformin, the 2025 meta-analysis data, and the real limitations of the current evidence base. It covers who berberine is actually used in, what the safety and interaction profile looks like, and why formulation and dose matter more than most supplement labels suggest.
With clinical insight and a GP’s perspective, this episode gives berberine the conversation it deserves.
