Hi,
Regarding your Hashimoto's, you already have some thyroid cell destruction from thyroglobulin antibodies having destroyed thyroid tissue. LDN can reduce production of these antibodies and this would cause future thyroid cell destruction, whereas right now with antibody destruction, the rate of cell destruction is decreased. Eventually some cells can regenerate and you may end up needing a lower dose of replace hormone again.
In other words, LDN will do more towards stopping disease progression and it can help restore some thyroid tissue as a natural part of the healing process. Whether this will cause you to eventually regain complete thyroid function depends on the extent of your thyroid cell damage and how well you regenerate new cells. Best, Elaine
