Women are being urged to reconsider their multi-vitamin consumption during pregnancy

An Australian study reveals almost 90-percent of participants were using supplements to meet dietary requirements during pregnancy.

Lead researcher Dr Linda Gallo says over supplementing can pose health risks and marketing around multi-vitamins can be misleading.

She says there's been a huge marketing push for multi-vitamins.

Dr Gallo recommends a balanced diet to minimise the need for supplements unless recommended by a health professional.
