Angela has been asked recently about how to improve sleep and specifically the effect of caffeine on sleep. In this episode, she explores the impact of caffeine on the body and the ways it can affect sleep and performance.

Angela shares in detail how the body processes and reacts to caffeine and explains how understanding your genotype can help you to optimise your health.


Sleep can support anti-ageing, the burning of fat,  improve focus, productivity, creativity, concentration and protect your brain against cognitive decline.

It’s easy to reach for caffeine when you are really exhausted but over time you are depleting your adrenal glands and if taken at the wrong time caffeine it can disrupt deep sleep.

 You can use caffeine safely and effectively as a powerful neutropenic for enhancing cognitive function but without comprising your ultimate superpower – sleep

Research shows that each person’s unique genetic makeup will determine the degree to which caffeine will affect them

Polymorphism divides people into one of two groups the fast metabolizers and the slow metabolizers of caffeine

Knowing how your body processes caffeine can help you to know how much caffeine you should drink in a day

Getting your DNA tested can help you to understand your genotype and optimise your health in relation to a number of key areas

‘Without deep sleep, you are more likely to get sick more likely to feel depressed and gain an unhealthy  amount of weight’
