How have we reached this point, why do many of us feel our diets aren’t giving us everything we need to stay healthy and productive, and do these supplements live up to the bold claims that many manufacturers make for them?

She tells us how our busy lifestyles are leading more of us to turn to dietary supplements, talks us through the rise in the consumption of protein powders and meal replacement drinks, and explains how, underlying health conditions aside, we can all get everything our bodies need to stay healthy by eating a balanced diet.
