We generally don’t recommend using Amazon for supplements due to known climate control and counterfeit issues that have resulted in supplements containing heavy metals and other toxins, with the exception of the few small company, very heat tolerant binder ones listed below. We’ve have multiple reported issues from our clients who tried getting vitamin and herbal supplements on Amazon that ended up being ineffective or contaminated.

Always work with your veterinarian. This is provided for informational and educational purposes.

International Shipping Options:

Here is an international shipping option you may want to consider for more affordable international shipping options from the United States.


If you use them, you of course, do so at your own risk, and you’ll need to know your countries’ laws and customs regarding shipping supplements. That said, a few of our clients have shipped supplements to their homes outside the United States using these services, and had a good experience. Always do your own research as we aren’t involved with these companies and we can’t be responsible for, or able to help with any issues you might encounter with shipments through them.

For those looking to order supplements internationally (excluding the UK), you may want to explore DSS (Use Registration Code: BO1171) .
