I unfortunately had to give one star to be able to write this review. We bought 2 x Iron tablets from Holland and Barrett store. After a couple of weeks of taking them i noticed an unusual smell when opening the lid, i tipped the remaining tablets out of the container and seen several were greenish and looked mouldy. I contacted H&B via Twitter who were not helpful and very unconcerned, they told me to take back to the store where a refund or replacement was discretionary.. I find this very concerning as they did not want to investigate they cause or even be bothered to examine the contamination.. With the facts that no investigation or concerns from H&B it now makes me wounder how many other products they sell have been contaminated and they have failed to investigate them. I will never purchase H&B products again. PLEASE BE WARNED IT COULD MAKE YOU ILL OR EVEN WORSE.
