If you suffer from constipation - this product is a HUGE help. I left my bag on the kitchen counter one morning and when I got home in the afternoon I found the bag torn open and only a few tabs left. Both my dog and my cat had eaten some! Who knew animals could benefit from Chlorella? I figure there must be something in it that's good for us if our animals eat it too. Don't worry - they were fine. You can't O.D. from eating too much Chlorella unless you have an auto-immune disease :)
