The proof a vitamin pill really CAN help you see better
Millions of people take them in a bid to boost their wellbeing, but when it comes to dietary supplements I have always been a sceptic.
Over the years, I’ve seen so many of these pills or potions hailed as the next big thing, only for them to come to nothing — or even in some cases to make your health worse.
Take beta-carotene. This antioxidant, found naturally in vegetables such as carrots, was very popular as a supplement. That is until a study, looking at whether it could help prevent lung cancer in smokers found that those taking high doses of beta-carotene were dying sooner than those who weren’t.
One possible problem with supplements is that once you start taking them, your body immediately thinks you no longer need that substance from your diet, so it stops extracting it from what you’re eating. Since your body is so good at compensating, it always seemed to me that unless you’re genuinely deficient in something, supplements are expensive and unnecessary.
That’s why I’ve shunned them, preferring instead to get all the nutrients I need from eating a balanced diet rich in fruits and vegetables. So, you can imagine how dubious I was when asked to take a supplement that would apparently improve my eyesight. And my complete surprise when it actually worked.
