health P opping a multi-vitamin onto your child’s plate to make-up for any shortfall in nutrients seems like a sensible approach, doesn’t it? Few and far between are the parents who believe their child eats a truly balanced and wholly nutritious diet. So why not add a multi-vitamin to be sure? Well despite the comforting promises on vitamin labels, there are risks to supplement use that parents need to be aware of. The question of ‘to supplement or not’ isn’t a straightforward one. Pills that claim to make your child smarter; make their bones stronger; give them more energy; improve their immunity – there is a supplement on offer for any concern a parent may have. The global market for dietary supplements is growing at an astounding rate. Yet regulation and testing is not as stringent as you 30 www.playtimes.com.hk might expect. It is often highlighted that US Federal law “does not require dietary supplements to be proven safe to FDA's satisfaction before they are marketed. For most claims made in the labeling of dietary supplements, the law does not require the manufacturer or seller to prove to FDA's satisfaction that the claim is accurate or truthful before it appears on the product.” In Hong Kong dietary supplements are classified either as pharmaceutical products, Chinese medicine or ‘general food’. A report by the HK Consumer Council found that of 76 multi- or single vitamin supplements reviewed (including supplements aimed at children), only 16 were actually registered as pharmaceutical products, despite the potential side- effects of vitamin use, prompting calls for tighter controls. Regulation does vary by country, but in general vitamin and mineral supplements are not tested and scrutinised in the way that prescription medicines are. You should therefore treat any health claims made by vitamin companies with a good dose of skepticism. The lower levels of scrutiny applied to children’s vitamins, relative to prescription medicines, means that you may not always get what you expect either. A report by Consumer Lab in the US found that 80 per cent of children’s gummy vitamins tested did not have the same amounts of vitamins and minerals as listed on their labels. Impurities were also found. Katie Young, a Qualified Clinical Nutritionist, states that “many over the counter supplement brands contain junk ingredients, or cheaper, less absorbable forms of nutrients and some may do more harm than good. As with anything, don’t fall pray to marketing hype.” Vitamins aimed at children are often loaded with artificial colours, flavours and sugar to make them more palatable. As Katie points out, “sugar is an anti-nutrient and lowers immunity, so is counter productive.” So if the magic multi-vitamin pill isn’t quite so magical, what should parents do? There is a whole alphabet of vitamins and minerals that are absolutely essential to a child’s health and many parents feel concerned that their child’s diet may not be adequate. Yet the advice on using vitamin and mineral supplements is constantly evolving and often frustratingly contradictory. One thing experts agree on is that parents should seek medical advice before giving their child any form of supplement. “It is extremely important to see a professional who can determine which vitamins and minerals are needed and provide you with high- grade supplements targeted to your child’s specific needs. I know many people like to order supplements online and self-prescribe, as they may be cheaper - but you get what you pay for. You would not do this with prescription drugs and should not do this with supplements,” Katie says. Seeking professional guidance is particularly important if your child takes other medicines as “ you need to know if any nutrients may have contraindications with other nutrients, medications or conditions. Some supplements can interact with medication.” Another thing most experts agree on is that when it comes to vitamins and minerals, you can certainly have too much of a good thing. There are dangerous side-effects to overdosing on vitamins, so caution is warranted. Accredited Practicing Dietitian, Violet Man, says: “Children of different ages can be different sizes and pills are based on body weight, not on age. It’s best to talk to your doctor or dietitian about the right type and correct dosage.” She highlights that excessive vitamin A can be toxic, causing loss of appetite, nausea, itching skin. Overdosing on vitamin D can lead to calcium being deposited into soft tissues, vomiting and diarrhoea. A condition called hypercalcemia can be caused by excessive calcium and vitamin D supplementation; care is needed if using either of these supplements alongside a multi-vitamin that may already contain them. Katie explains that, “some vitamins are hard
