G.I Hist Support by Neuro Biologix is a dietary supplement offered in the form of vegetarian capsules, specifically designed to support gastrointestinal health. Each bottle contains 60 vegetable-based capsules. The supplement aims to provide assistance in managing responses to food and environmental factors that may contribute to gastrointestinal discomfort.

The formulation includes key ingredients such as Quercetin, N-Acetyl-L-Cysteine (NAC), and Vitamin C, all of which are recognized for their roles in supporting the body's natural histamine response and immune function. Quercetin is a flavonoid that may help stabilize mast cells, thereby controlling the release of histamines. N-Acetyl-L-Cysteine is a precursor to glutathione, an important antioxidant that can aid in detoxification processes. Vitamin C serves as an antioxidant and supports immune system health.

Other supportive components include Bromelain, a proteolytic enzyme derived from pineapple that can aid digestion and support normal inflammatory responses; and the amino acid L-Glutamine, which serves as a fuel source for enterocytes, the cells lining the intestines. Additional ingredients include Turmeric extract, known for its anti-inflammatory properties, and Zinc, which is essential for maintaining the integrity and function of the intestinal barrier.

G.I Hist Support is free from common allergens such as gluten, dairy, and soy, making it suitable for individuals with dietary sensitivities. The product is also non-GMO. Recommended usage is as directed by a healthcare professional. This supplement is intended to support overall gastrointestinal health, particularly in the context of food and environmental sensitivities.
