Are supplements a quick health fix or can vitamins actually be bad for you?

Vitamin pills are big business – from chewable ones for children and tablets especially tailored for women going through the menopause to essential oils for dodgy joints and high-dose vitamin C to pep up your immune system, there’s a supplement for everyone.

But can vitamins actually be bad for your health?

It seems that your daily pill can do more harm than good. Indeed, last week saw the revelation that fish oil capsules have been linked to high levels of prostate cancer – a shock for the millions who take fish oils or omega-3 fatty acids every day in the quest to ease joint pain, improve heart health and fight mental decline.

A study of more than 2,000 men found that those with the highest levels of omega-3 in their blood were 71 per cent more likely to develop the most lethal form of prostate cancer, and 44 per cent more likely to develop low-grade prostate cancer.

And it’s not just omega-3 that is under scrutiny. According to Dr Alan Kristal, who led the study at the Fred Hutchinson Cancer Research Centre in Seattle, there is surprisingly little evidence that any vitamin or mineral pills prevent disease – unless people are suffering from a nutrient deficiency.
