Warning do not buy!
I have no idea if this product works. I'm sending it back immediately. After reading into the comments on here someone wrote that theirs arrived with a sticker covering the expired expiration date....so out of curiosity I went to check mine.  And sure enough sticker over top, once I peeled it back it shows expiration date from TWO YEARS AGO!  Swanson is never getting a dollar from me again & I will be spreading the word on them to my herbalist & vitamin taking friends.
