G.I. Hist Support is a formula designed to assist patients who have trouble processing external sources of histamine-rich foods and nutritional elements. This formula is especially helpful for those with genetic weaknesses in A01C (Diamine Oxidase), the main enzyme responsible for the degradation of ingested histamine.*
A key active ingredient in G.I. Hist Support is porcine-derived diamine oxidase (DAO), and research suggests that DAO derived from porcine kidney appears to have identical action to DAO derived from porcine intestine. Along with 5 other ingredients shown to support allergy relief, GI Hist is one of the best supplements on the market that includes key cofactors along with high dose DAO.*
Each ingredient is clinically tested to assist with histamine degradation and the oxidative stress created by histamines.*
Adults take 1-2 capsules no more than 15 minutes before the consumption of histamine-rich foods. Children take one capsule no more than 15 minutes before the consumption of histamine-rich foods or take as directed by your healthcare practitioner.
As a daily maintenance support product, take 2 capsules in AM and 2 capsules in PM.

Very strong for when I’m having a migraine with neck and shoulder spasms
I have used a lot of sprays rubs and patches. Finally one that works.
Lipitrol Ox is one of the best supplements to help keep your cholesterol level down.
Very satsfied. It's easy to use and helped relieve my discomfort
I would do a commercial for this product. For me it absolutely works so well. I love the fact that there’s hardly any ingredients in it at all and yet it works. I have used this for years and will continue to use it.
I'm very impressed with Pharmedico and the product! The doctor answered all my questions and was very knowledgeable.
I have used this product for the last few years. I take it prior to a vacation/cruise and then continue to take it while on the vacation/cruise. It seems (knock on wood) to either prevent or lessen any illness picked up. Recommend trying.
It works quickly! It does have a strong mentol smell. Works great..
