Hyperimmune Egg: Uses, Safety & Side Effects

The bottom line

Hyperimmune egg is a dried egg product from hens vaccinated against common germs, so the eggs contain extra antibodies (mainly IgY). Some small studies suggest possible benefits for gut health and immune support, but the overall evidence is limited and not strong. People with egg allergy should avoid it, and pregnant or breastfeeding women should check with a doctor first.

Overview

Hyperimmune egg is a special egg product made from hens that have been immunized (vaccinated) against a range of common bacteria and other germs. In response, the hens produce eggs that are rich in antibodies, especially a type called IgY (immunoglobulin Y). These antibodies pass into the egg yolk and white.

The eggs are usually dried into a powder and sold as a supplement. You may find it as a stand-alone powder, in capsules or tablets, or blended into protein and wellness drink mixes. It is sometimes marketed for immune support, gut health, and overall wellness.

It is important to know that this is a food-based product, not an herb or plant. It is closely related to ordinary chicken eggs, so the same allergy concerns apply.

How it works

The main idea is based on antibodies. When hens are immunized against certain germs, their immune systems make antibodies (IgY) that end up in the egg. When you eat the egg product, these antibodies are thought to travel through your digestive tract and may attach to specific bacteria or their toxins, helping to keep them from causing trouble.

Eggs also naturally contain proteins, growth factors, and other nutrients that supporters say may help support the gut lining and immune function. Much of this is based on laboratory and animal research, and it is not clear how much of the antibody activity survives stomach acid and digestion in people.

Because these mechanisms are mostly studied in the lab, you should view claims about how it works with healthy skepticism until larger human studies confirm them.

Also studied for 8 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Athletic performance
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in recreationally active young men shows that taking hyperimmune egg (Immune26, Legacy for Life) orally in a dose of 4.5 grams daily for 2 days, then 9 grams daily for 2 days, then 13.5 grams daily for 6 days, reduces the maximum heart rate and increases peak power during three 5-minute submaximal exercise bouts on a treadmill when compared with placebo. Poor study design limits the reliability of this research.

Insufficient Reliable Evidence To Rate Cystic fibrosis
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in cystic fibrosis patients aged 2-32 years who have had a prior infection with Pseudomonas aeruginosa shows that using a hyperimmune egg yolk extract containing 50 mg of IgY antibodies to two strains of P. aeruginosa as a gargle once daily at bedtime, and then swallowing the liquid, prolongs the time to the second infection when compared with patients who do not receive the gargle. During follow-up of 36-92 months (mean 57 months), patients using the gargle had 2.5 positive sputum cultures for P. aeruginosa per 100 months of observation, compared with 13.7 per 100 months in the untreated control group. In the treated group, no patients became chronically colonized with the organism, compared with 24% of patients in the control group. In further follow-up lasting up to 12 years, the treated patients were switched to an egg extract containing 50 mg of IgY antibodies against six strains of P. Aeruginosa, which was used as a gargle for 2 minutes once daily and swallowed. There were 2.3 positive sputum cultures per 100 months of observation, and 2 patients developed chronic colonization with P. aeruginosa. In the untreated control group, there were 7 positive sputum cultures per 100 months, and 7 patients became chronically colonized. The reliability of this research is reduced by lack of randomization, since treated patients from Sweden were compared with untreated patients from Denmark. Additionally, some, but not all, of the evaluated patients were receiving chronic treatment with azithromycin.

Insufficient Reliable Evidence To Rate Helicobacter pylori
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that taking a specific defatted egg powder product prepared from eggs of hens immunized with Helicobacter pylori urease (Ovlagen, GHEN Corp., Japan), 900 mg three times daily after meals for 4 weeks, is associated with a reduction in urea breath test values, but not complete eradication of H. pylori, in asymptomatic volunteers with H. pylori-positive urea breath tests. Other clinical research shows that taking a yogurt drink containing H. pylori urease-specific IgY 15 mg, Lactobacillus acidophilus, and Bifidobacterium species, 150 mL three times daily for 4 weeks, is associated with a 40% reduction in urea breath test values when compared with baseline in volunteers positive for H. pylori by urea breath test. Taking the same yogurt drink without IgY is associated with a 15% reduction in urea breath test values when compared with baseline. The validity of this finding is limited by the lack of a direct comparison to the control group.

Insufficient Reliable Evidence To Rate Hyperlipidemia
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that taking a specific hyperimmune egg powder formulation (Immune26, Legacy for Life) for 26 weeks does not significantly lower cholesterol when compared with baseline. The validity of this finding is limited by the lack of a comparator group.

Insufficient Reliable Evidence To Rate Osteoarthritis
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that some patients with osteoarthritis might have reduced subjective measures of joint pain or swelling after taking a specific hyperimmune egg powder formulation (Immune26, Legacy for Life) for 2 months when compared with baseline. Poor study design limits the reliability of this research.

Sources Ref 13207
Insufficient Reliable Evidence To Rate Periodontitis
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that using lozenges containing hyperimmune egg yolk immunoglobulin (IgY) from hens immunized with Porphyromonas gingivalis proteinases (gingipains) reduces gingival bleeding index and oral P. gingivalis counts more than placebo in people with periodontitis. Two lozenges, each containing 12 mg powdered IgY, were dissolved in the mouth 3 times daily after meals for 8 weeks.

Insufficient Reliable Evidence To Rate Rheumatoid arthritis (RA)
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that taking a specific hyperimmune egg powder formulation (Immune26, Legacy for Life) for 2 months does not significantly improve subjective measures of RA symptoms when compared with baseline. Poor study design limits the reliability of this research.

Sources Ref 13207
Insufficient Reliable Evidence To Rate Rotaviral diarrhea
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that taking a preparation of purified egg yolk immunoglobin (IgY) from hens immunized against strains of rotavirus, 10 grams daily in 4 divided doses for 4 days, can modestly decrease rotaviral diarrhea in children aged 2-24 months. The IgY preparation seems to significantly reduce stool output and oral rehydration solution intake on day 1 of treatment. But it does not seem to significantly reduce stool on subsequent days. Children treated with the IgY also seem to clear rotavirus from the stool more quickly when compared with children receiving placebo.

Safety & precautions

For most healthy people without egg allergy, hyperimmune egg is generally considered low-risk because it is basically a concentrated egg product. However, there are important cautions.

Do not use it if you have an egg allergy — it can cause a serious allergic reaction. People with high cholesterol or who are watching their fat and cholesterol intake should be aware that egg products contain cholesterol and fat.

For pregnancy and breastfeeding, there is not enough reliable safety information, so it is best to be cautious and talk with your doctor or pharmacist before using it. The same goes for young children and people with weakened immune systems. Always choose products from reputable companies, since supplements are not tightly regulated.

Side effects

Reported side effects are usually mild and may include stomach upset, bloating, gas, or loose stools, especially when starting out or taking larger amounts.

The most serious concern is an allergic reaction in people sensitive to eggs. Signs can include hives, swelling, trouble breathing, or wheezing. If you have any of these symptoms, stop using it and seek medical care right away.

Because it is a dairy-free protein product, it may not suit everyone, and individual tolerance varies.
