Yes, a HTMA is a great idea. You will want to find the right practitioner first, someone whose approach and demeanor you feel good about. There are two labs, Trace Elements Inc and Analytical Research Labs. A practitioner will work with one or the other. You may also want to consider whether you want to heal full time, which can take less time, or heal as a lifestyle, which can take years. The latter is Dr. Lawrence Wilson's program, the former may be with Perfect Balance, who uses more magnesium to heal faster. Both are effective. Find the right practitioner first, then have them do your HTMA. Many of us can share our experiences choosing different routes.
