One sided conversation article cites flawed data as evidence against vitamins

An article published this week on The Conversation titled ‘Health Check: four myths about vitamin supplements’ asserts that vitamin supplements are a waste of money because “there’s no convincing evidence that vitamin supplementation benefits people who don’t actually have a vitamin deficiency”. The article, written by Neil Watkins, Petre Chair in Cancer Biology, Lab Head - Cancer Developmental Biology at Garvan Institute in Sydney, goes on to outline the alleged “myths” about vitamins. What the author fails to grasp is that vitamin deficiency is, until it starts causing macroscopic problems such as rickets or pernicious anaemia, silent.
