I have only just come back to using Seagreens after a while off, although still using other supplements, so it's early days to report on any positive changes. My main reason is suspecting low Iodine levels or low uptake as the outer corners of my eyebrows are very thin and sparse which I have read is a known feature of low iodone. I dose my cats with pet food ingredient and they have luxurious silky coats so we'll see if I get similar results! As for service I was thrilled to have received my package, safely tucked in a safe place within a couple of days of ordering with a lovely personal note in the package, which was a nice touch. Will report back after a month of use.
