I did not received the product I needed and ordered. Instead I received dr. Mercola d3 and k2. It was no information on the webpage of other contact ways than email. I emailed two days ago and received answer to wait three days. I found the number another place and called. Nobody picked up the phone. I left a message on the answering machine and received no service. Another place I saw that they had a chat but it did not exict on the webpage. I am truly dissapointed. I ordered the do not age d2 after recommendation from my doctor friend seeing I got chronic low d vitamin. I needed this product for my condition.
