I originally contacted this company in March of 2017 about their RX Vitamin supplements. I asked them in writing if they purchase these supplements directly from RX Vitamins, and they gave me an answer that made it sound like they do, but looking closer as their wording, I was suspicious if they actually do buy from them directly. So I asked again. The next response was that they are not allowed per company policy to state what vendors they use. But in the meantime, I had contacted RX Vitamins directly. They stated they do not sell to online pharmacies and do not know how this company is obtaining their supplements. They also stated that they do not back any of their supplements that are not sold directly through a veterinarian's office. So, I reported VetRXDirect to the Iowa board of pharmacy, the BBB, and the Iowa attorney general's office. The company responded back and was adamant that there is nothing wrong with these supplements, stating they are not expired, counterfeit, or tainted. So, about a month ago, I decided to give the company a try, because I was wanting to save some money. Big mistake. I ordered the RX Vitamins Renal support and the RX Vitamins Phos-bind. My dog has taken these supplements before. I gave her the supplements purchased from VetRxDirect twice. Both times she vomitted. The vomitting immediately ceased upon ceasing to give her the supplements. So, I filed more reports, including one with the FDA. To date, the company has not refunded my money even though I have requested it in writing. I am not sending the products back because a) they cannot resell them due to opening them; b) I am holding on to them in case the FDA needs to inspect them. I would also suggest reviewing their Yelp reviews. I've never seen so many one star ratings in my life.
