Low Dose Immunotherapy ​(LDI)

What is LDI?

Low Dose Immunotherapy (LDI) is a therapy that is almost identical to the Low Dose Allergy (LDA) therapy (see our LDA page). While LDA works very well for many types of allergies, LDI can work for various autoimmune disorders and chronic infections.


After Dr Shrader developed LDA for multiple different types of allergies, he noted that various autoimmune disorders tended to be associated with possible low-lying infections with various bacteria. He made some LDA formulations using antigens for some of these, and had very good success treating several different autoimmune disorders including Rheumatoid Arthritis, Crohn's, and others. Dr Ty Vincent later came along and extended the idea to treat Lyme Disease as well as coming up with several other formulations which work very well for several other diseases and infections..

Differences between LDA and LDI

Probably the biggest difference between LDA and LDI is who came up with the therapy - Dr Shrader trademarked the LDA name, so Dr Vincent coined LDI. There are also some differences in how they are dosed and used - LDA typically has relatively fixed doses while LDI requires a very wide variety of dosing with everyone having their own specific dose. Typically with LDI, if you give a dose that's too high you can make the disease symptoms worse, too low a dose will usually do nothing, and "just right" can potentially work wonders. Because of the possibility of dosing too high we often start at a dose we think will be too low and work up from there.
