Overview Information

Hyperimmune egg is an egg from a hen that has been vaccinated against certain infectious diseases. The hen makes antibodies against these diseases. These antibodies pass into the hen's eggs. People remove the antibodies from the egg yolks and use them as medicine.

Hyperimmune egg is used for cystic fibrosis, a digestive tract infection that can lead to ulcers (Helicobacter pylori or H. pylori), diarrhea caused by rotavirus, and other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Antibodies contained in hyperimmune egg are thought to stimulate the immune system and help the body fight disease.


Uses & Effectiveness?

Insufficient Evidence for

  • Cystic fibrosis. Early research shows that taking hyperimmune egg from hens vaccinated with a specific bacteria called Pseudomonas aeruginosa reduces the number of times this bacteria is found in the saliva.
  • A digestive tract infection that can lead to ulcers (Helicobacter pylori or H. pylori). Early research shows that taking hyperimmune egg from hens vaccinated with H. pylori reduces how much of this bacteria is found in the stomach. This might reduce the risk of ulcers.
  • High cholesterol. Early research shows that taking a specific hyperimmune egg product (Immune26, Legacy for Life) for 26 weeks does not lower cholesterol.
  • Osteoarthritis. One research study found that some people with osteoarthritis feel less joint pain or swelling after taking a specific hyperimmune egg product (Immune26, Legacy for Life) for 2 months. But some researchers believe this study was not well designed and the results might be questionable.
  • A serious gum infection (periodontitis). Early research shows that taking hyperimmune egg from hens vaccinated with bacteria found in the mouth reduces some symptoms of gum infections.
  • Rheumatoid arthritis (RA). One research study found that taking a specific hyperimmune egg product (Immune26, Legacy for Life) for 2 months does not improve RA symptoms.
  • Diarrhea caused by rotavirus. Early research shows that taking hyperimmune egg from hens vaccinated with rotavirus can decrease diarrhea caused by rotavirus by a small amount in children aged 2-24 months.
  • Athletic performance.
  • Other conditions.
More evidence is needed to rate the effectiveness of hyperimmune egg for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Hyperimmune egg is POSSIBLY SAFE for adults when used appropriately for up to 26 weeks. Some people may experience diarrhea, gas, and bloating.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if hyperimmune egg is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Children: Hyperimmune egg is POSSIBLY SAFE when used in children aged 2-24 months for up to 4 days.

Egg allergy: Hyperimmune egg is made from chicken eggs. There is some concern that people who are allergic to chicken eggs might also be allergic to hyperimmune egg products.



We currently have no information for HYPERIMMUNE EGG Interactions.



The appropriate dose of hyperimmune egg depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for hyperimmune egg. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
