Former All Blacks skipper Richie McCaw and his wife Gemma McCaw were part of an ad campaign for Good Health turmeric products.
A Good Health spokeswoman said it had been aware of the complication for some time.
"We take care to educate retailers in the pharmacies and health stores that sell our products about this," she said.
"Good Health also carries warnings on our website, and we are currently working our way through our Turmeric 15800 Complex and Turmeric Extra Strength product range packaging to ensure that it also carries warnings.
"Good Health naturopaths are always on hand to take queries from retailers regarding contra-indications, and we take a conservative view on these."
