Hardly a week goes by without another headline slating multivitamins. It doesn’t seem to matter how many studies show that a daily multivitamin is good for you, still the naysayers talk about expensive urine and not much else.
In a bid to set the record straight on what is actually a very healthy habit, we’ve taken a closer look at two of the most common myths about multivitamins:
Myth 1: There’s not enough evidence
One reason commonly cited against taking a daily multivitamin is that there isn’t enough evidence from randomized controlled trials to make a recommendation either way. On the surface there’s logic to this view. However, the reality is that it will likely never be possible to conduct randomised trials that are long enough to fully test the effects of a multivitamin on your long-term health. Then you look at all the evidence to date, the potential health benefits of taking a daily multivitamin appear to outweigh the risks for most people1. Emerging scientific evidence, often at levels above the Recommended Daily Allowance (RDA), may also reduce chronic disease risk and promote long term optimal health.2-6
The Harvard School of Public Health describes a daily multivitamin as a ‘nutrition insurance policy’. In a scientific review on the subject, researchers concluded that, ‘pending strong evidence of effectiveness from randomized trials, it appears prudent for all adults to take vitamin supplements.’7
Myth 2: Your diet provides everything you need
Many will argue that your diet provides everything you need and that a daily multivitamin is an indulgent waste of money and time. For those who consistently eat a balanced diet containing a wide variety of organic fresh fruits and vegetables, whole grains, high quality protein and plenty of beneficial fat, and who also take into account the fact that nutritional needs differ according to what’s happening in life, the benefits may be questionable. There are very few people however, who can confidently say that they do this. It’s no mean feat to consume 7-10 portions of organic fruit and veg daily and to consciously think to add extra servings of magnesium-rich foods into your diet when you’re feeling particularly stressed.
Unfortunately, a large proportion of the population relies on processed, nutrient-lacking convenience foods for their staple diet and only 8% of children and less than 30% of adults meet the 5-a-day fruit and veg recommendations.8 Research now shows that we actually need to be aiming for 10-a-day if we really want to harness the health-protective powers of plant foods.9
Your daily food intake should be held in the highest regard in terms of life’s priorities. For most however, the reality is very different. Food often comes a sorry last, lagging far behind work, social lives and even household chores in terms of priorities. In our fast-paced world, a daily multivitamin has become a necessity. This doesn’t mean we can’t strive towards being part of a society where food is given the thought and attention our health deserves; it just means we need to work with where we are now whilst we aspire to improve.
If you’re looking for the best of health, choose a daily multivitamin that’s targeted to your needs and contains therapeutic amounts of essential vitamins and minerals inactivated, body-ready forms.
