Vamped Sanguinarian Survey
Got blood? Many sanguinarians drink animal or human blood for health reasons. Picture:

Earlier this year, I spent months preparing my Sanguinarian Survey and finally released it on September 9, 2019. The survey was kept open for respondents until October 28, 2019. This allowed me to collect data for 50 days.

For those of you that don’t know, sanguinarians are people that drink human or animal blood for health reasons. The purpose of my survey was:

to identify similarities and patterns concerning diet, health conditions, and lifestyle habits of sanguinarians—or “vampires”—within the Vampire Community, specifically those who consume human and/or animal blood and experience notable health benefits. 

By analysing the data collected, I hope to determine statistical patterns that will provide a greater understanding of why consuming human and/or animal blood improves health conditions for certain people, providing a possible avenue for further examination by medical professionals and researchers.

Sanguinarian Survey 2019

Sanguinarians and members of the online vampire community are usually very private people and keep their blood drinking habits to themselves. I knew this would make getting respondents challenging, but I didn’t let it discourage me. Secretly, I was hoping to get 100 respondents for the survey and I ended up with 73. I was still super happy with this amount.

The entire report is a 110 pages and can be downloaded from my personal website. I kept the data raw as I am not a medical professional and therefore not qualified to interpret it.

I reached out to Dr. Tomas Ganz, who is Professor of Medicine and Pathology at UCLA, and a Principal Investigator at the UCLA Center for Iron Disorders and asked what he thought of the data collected. He provided a response that I included in the final published report.

I hope everyone takes the time to read the report in its entirety, but in case you don’t, below are some key findings from the executive summary:

The report includes an acknowledgement section, but I would like to personally thank everyone in the online vampire community that participated in the survey. This survey wouldn’t have been possible without your feedback! Reading some of your kind comments at the end of the survey warmed my heart.

Now that I have a more defined scope of the conditions that affect sanguinarians, I am going to continue my research in 2020. I plan to administer more targeted surveys. I hope that as time goes on, more sanguinarians will choose to participate. The higher amount of respondents, means that better data will be collected.

More research will create a better awareness of this condition and more understanding from others. My ultimate goal would be to see funded studies on the topic.


I would like to thank everyone that helped distribute the survey and Anthony Hogg and Dea Schofield for assisting with the editing process. Lastly, thank you to Dr. Tomas Ganz for always responding to my many emails and questions over the last few years. Your educational experience has been such a valuable tool in this entire research process.
