There have been remarkably competent and influential advocates of the positive effects of consuming high doses of vitamin C. Of these, Linus Pauling stands out, not only because he won the Nobel Prize but also because he was so adamant that vitamin C can treat many health problems.

In the next couple of blogs, we’ll consider whether it’s worth supplementing vitamin C. We’ll...

Lots of people have recently become interested in whether supplementing with L-tyrosine can improve performance at work and lift mood, in part because of the opinions put forward by scientists and influencers on podcasts and social media.
