Discover Elite IgG™

Elite IgG™ is an award winning, serum-derived immunoglobulin powder clinically proven to support robust immune function and optimal digestive wellness. Immunoglobulins work in your body by binding inflammatory, potentially toxic antigens within your digestive tract and prohibiting them from crossing the gut barrier. This has tremendous implications in supporting the restoration of a healthy inflammatory balance, a normal bowel pattern and stool consistency, and helping to reverse and repair “leaky gut”.

Elite IgG also provides powerful serum proteins, 18 crucial amino acids and rare growth factors that are essential for optimal vitality. Unlike inflammatory cow’s milk-based colostrum and IgG products, Elite IgG™ is sourced only from patented, pharmaceutical-grade Immunolin® Bovine Immunoglobulin Protein Isolate. Each serving provides over 1,000 mg of Immunoglobulin G and is completely free from dairy, GMOs, sugar and antibiotics.

Lactoferrin is an iron binding protein that is only found in milk-based products like colostrum. What you will find in Elite IgG™ is a near identical protein, called transferrin. Transferrin is quite similar in iron binding coordination, amino acid sequence, and protein structure to Lactoferrin.

Trandferrin makes up 6-7% of the major protein components in ImmunoLin® Serum-Derived Immunoglobulins found in Elite IgG™. What makes Transferrin better than lactoferrin, besides there being absolutely zero lactose, is that its structure is much stronger and "polyclonal." This means more of it survives past the acidic stomach and lower GI tract than lactoferrin.

Transferrin also binds lipopolysaccharide (LPS), an important binding site on dysbiotic microorganisms, where it can act as a cell wall disruptor, supporting your body's optimal immune health and function.

  • 𝐀𝐖𝐀𝐑𝐃-𝐖𝐈𝐍𝐍𝐈𝐍𝐆 𝐆𝐔𝐓 & 𝐈𝐌𝐌𝐔𝐍𝐄 𝐒𝐔𝐏𝐏𝐎𝐑𝐓: Immunolin has won Supply Side West's 2022 Ingredient of the Year for Gut Microbiome Health! Immunoglobulins help bind toxic & inflammatory antigens in your gut & can prevent them from damaging your gut lining (“leaky gut”). Only serum-derived immunoglobulins, such as Elite IgG Immunolin, contain Transferrin, an immune-supportive molecule that also fosters an optimal microbial balance in the gut & discourages dysbiosis.
  • 𝐂𝐋𝐈𝐍𝐈𝐂𝐀𝐋𝐋𝐘 𝐏𝐑𝐎𝐕𝐄𝐍: Evidence from several studies shows that the immunoglobulins and other bioactive peptides found in the serum-based immunoglobulins (SBI) contained in Elite IgG™ help maintain gut-barrier function. In vitro studies have demonstrated that SBI binds to many different microbial components present in dysbiotic microorganisms, which are known to activate the intestinal immune system (inflammation) if allowed access through a damaged intestinal epithelium (leaky gut).
  • 𝐏𝐇𝐀𝐑𝐌𝐀𝐂𝐄𝐔𝐓𝐈𝐂𝐀𝐋 𝐆𝐑𝐀𝐃𝐄: For 15 years, 2,000+ production lots of the serum-based immunoglobulins (SBI) contained in Elite IgG have been manufactured utilizing the same rigorous isolation, purification & filtration methods. These methods are deployed in a cGMP facility that employs extensive precautions and procedures to ensure the safety, cleanliness, stability & consistency of each batch. Elite IgG delivers a clinical dose of Immunoglobulin-G (IgG) of over 1,000 mg / serving.
  • 𝟏𝟎𝟎% 𝐃𝐀𝐈𝐑𝐘 𝐅𝐑𝐄𝐄: Elite IgG formulated with ImmunoLin® is lactose-free. Colostrum is a milk-based compound, thus products containing it include elevated levels of lactose (a sugar that is often poorly tolerated, resulting in GI distress for many of us). Elite IgG contains no lactose since it is derived from serum & not milk. Laboratory tests show that ImmunoLin® provides the highest percentage of immunoglobulins available compared to other commercially available colostrum supplements.
  • 𝐏𝐔𝐑𝐈𝐓𝐘 𝐈𝐒 𝐏𝐑𝐈𝐎𝐑𝐈𝐓𝐘: At Pure Thera, purity is priority. No exceptions. We pride ourselves in formulating pharmaceutical-grade nutritional supplements that are free from fillers and excipients that impact absorption, ingredients from China, gluten, grains, dairy, corn, soy, GMOs, as well as artificial preservatives, colors and flavors.

STORAGE: Keep tightly closed in a cool, dry place. Keep out of reach of children.

OTHER INGREDIENTS: Both the powder & capsules contain a small amount of sunflower lecithin.

    Won't go without it!

    I take this every evening. It is the only thing I have found to keep me regular. I must avoid laxatives as they stain your colon internally, making it challenging for the doctor to see the difference between healthy and unhealthy tissue during a colonoscopy. I trust that this also has immunity benefits.
