I have been supplementing with B12 for over 2 years however since coming to Thailand a year ago I have been using injections. Before I left the states I was tested and found that I am deficient along with 40% of other Americans. In Chiang Mai you can walk into any Pharmacy and pick up B12, testosterone and many different painkillers. I gathered information from four different sources you’ll want to check, but please do your own research and ask a professional.

It’s important to know how easy it is to find supplements when traveling Chiang Mai Thailand. I buy an extra supply of B12 when I am in Chiang Mai at Peera Pharmacy. It’s small enough to fit a few when cycle touring in my bags with no problems.
