New color is the result of better ingredients

The new formulation of Relyne GI has a slight golden color. This is caused by the inclusion of the new Schizophyllan Beta Glucan, a highly researched ingredient. However, the color change had no adverse effects on the consumption of the product during the study.

The following excerpt from the white paper, “Effects of Relyne GI with Beta Glucan (TBG-136™) on stomach health,” demonstrates why horse owners are excited about the new Relyne GI.

Non-glandular (NG) EGUS and severity gastric ulcer scores were significantly lower in the Relyne GI supplement treated group on days 28 and 35, compared to controls.

It’s also important to note that the reformulated RelyneGI was readily consumed by the horses and no adverse clinical signs were seen. Gastric Juice pH also remained low, and horses maintained their body weight.
