Professional Supplements & Nutritional Products Since 1998

I5represents an innovative approach to biotransformation for individuals whose health is constantly challenged. This all-natural, fructose-free formula includes ingredients that promote overall gastrointestinal health and support detoxification mechanisms and cytokine balance in the body. i5 features patented and proprietary ingredients, including 21 g of VegaPro, a non-GMO, vegetable-based protein, as well as IgG 2000 CWP, OncoPLEX (glucoraphanin), and arabinogalactan, a prebiotic. Professionals have reported the best results when i5 is combined with a modified elimination diet.*

  • Supports Improved Body Composition*
  • Supports Immune Function by Providing Immunoglobulins and Other Immune Factors*
  • Supports Healthy Cytokine Production*
  • Supports Intestinal Health*
  • Supports Detoxification*


VegaPro™ XYMOGEN’s proprietary blend of pea protein isolate, glycine, taurine, rice protein concentrate, and L-glutamine provides 21 g of plant-based protein per serving of i5. VegaPro is easily digested, is gluten-free, and achieves an amino acid score of 100%.[1,2] This amino acid profile supports protein metabolism and lean body mass. Aminogen® enhances protein digestibility and absorption.*

IgG 2000 CWP™ is an immunoglobulin concentrate from colostral whey peptides that delivers a minimum of 40% IgG immunoglobulin along with an array of compounds, including growth factors, sialic acid, lactoferrin, proline-rich peptides (PRPs), oligosaccharides, and gangliosides. Each of these components provides the user with different and complementary health benefits, such as fundamental support of immune function and modulation, lean body mass, brain and thymus health, microbiota modulation, and cytokine balance.*[3]

Oral consumption of immunoglobulins derived from colostrum is a means of supporting passive immunity, protecting the body, and eliminating unwanted molecules.[4-7] The most versatile, IgG, is capable of carrying out all of the functions of immunoglobulin molecules, accounting for IgG 2000 CWP’s broad range of immune-supportive effects.[8] A review of the research confirms that bovine colostrum supplementation confers other benefits, such as the maintenance of gastrointestinal integrity.[9-11] Oral immunoglobulins have been used in sports nutrition to support lean body mass,[12] physical exercise, and recovery following high-intensity training.[9,13] The 2.5 grams of immunoglobulins in each serving of i5 contribute to individual dosing requirements.*

OncoPLEX™ (glucoraphanin) This patented plant-based ingredient, also known as sulforaphane glucosinolate, is extracted from one of its most concentrated cruciferous sources—broccoli seeds.[14] An abundance of research demonstrates that when glucoraphanin is broken down to its active form, sulforaphane, it safely and effectively upregulates the body’s natural phase II detoxification enzymes.[15-17] This activity in turn supports antioxidant activity and helps protect cells, cell membranes, and tissues from free-radical damage.*

Arabinogalactan Sourced from the larch tree, arabinogalactan is a nondigestible, soluble dietary fiber that contains arabinose and galactose monosaccharides. It is considered an excellent source of fiber, favorably supports gut microflora as a prebiotic, and serves as a precursor to short-chain fatty acids, all elements that help support gastrointestinal health.*[18,19]
