Bests & Worsts Reviews from Amazon

I took this once a day with a meal for 8 days. I got a mild headache early on and a severe headache on the 8th. I also wanted to vomit. Please google "UC Davis study finds high arsenic levels in kelp supplements" and arsenic poisoning on Wikipedia for symptoms. The article of the UC Davis study does not specifically state that that this product in particular has high levels of arsenic but a picture of the Nature's Way brand was shown. They tested 9 kelp brands and 8 had high levels of arsenic. Please be careful if you choose to take this product and mark this review as helpful so other people may see this. Arsenic poisoning is not fun. I literally prayed for my life on that 8th day.
