Chlorella and heavy metals. I bought some Chlorella to detox from heavy metals - I used one month's supply and as I was about to start my second container - my feet developed bleeding sores and they felt like they were on fire. This lasted for 6 months and drove me to the edge of suicide. The problem was that I have 2 broken ankles which have implanted metal plates and screws - apparently the Chlorella attached itself to the metal and my body tried to get rid of it by doing it through the open sores on my skin on my feet. The supplier took this product off the market after having it tested by many scientists. My feet are still shedding skin after 3 years.
