Very profitable: Australia overdosing on dietary supplements

The marketing power of the complementary medicines industry has been highlighted by figures showing that half of Australian women and a third of men are taking dietary supplements.

Supplements are taken predominantly by well-nourished people and often in excess of recommended levels, a national study of almost 5000 people revealed.

Data from the 2011-2012 National Nutrition and Physical Activity Survey showed that dietary supplements use was higher among older people and among more affluent and educated groups who were already meeting recommended nutritional intake targets.

Researchers from Victoria’s Deakin University noted with concern that intakes of vitamins E, C, B12 and zinc from supplements were, in some cases, in excess of the recommended daily intake “which may result in toxicity”.

Nutritionist Dr Rosemary Stanton (PhD) said excess zinc intake could lead to diarrhoea, nausea, abdominal pains, lethargy and interfere with absorption of iron and/or calcium. But excess vitamin E intake was the main concern.

“The main thing is to warn patients having some types of surgery to stop taking vitamin E several weeks prior to surgery.

“This is because vitamin E may be associated with increased bleeding and haematoma. This could also apply to herbal and omega 3 supplements,” Dr Stanton added.
