Review: Good results - Has helped my health
Review: Not Sure this is Pure Fucoidan from my Experience!! - I had high hopes for this Fucoican and wish I could give it more stars — but definitely could not! I have used other Fucoidan products but this one did not have the same benefits. Usually, one will experience an improved inflammation level and well being — from both studies and my experience. Not so with this one! I actually felt sick and experienced pain and GI discomfort after taking this. I am not sure what is in this product, but it does not seem like Fucoidan. I cannot recommend this, but I can definately recommend Dr B___ on desertcart.
