The Story of YTE®

Young tissue egg extract (YTE) from a partially incubated hen egg was first discovered back in 1929 by a Doctor from Canada, John R. Davidson. He was observing fertilized hen eggs and realized that on day 9 of incubation the egg went through an incredible growth spurt that caused a tripling of the embryo inside the egg. He hypothesized that the nutrients inside the egg on this ninth day must be very powerful if they could cause a tripling in the growth cycle that was enough for a fluffy chick to hatch just 12 days later.

That was until 50 years later when a Norwegian scientist, Bjodne Eskeland, made the same discovery as Dr. Davidson that the fertilized hen egg contained very potent nutrients on the 9th day of incubation. As nutritional and scientific understanding had advanced a lot since 1929.

Eskeland and his partner, Nils Mortenson understood that the nutrients extracted contained a special combination of amino acids, peptides and protein fractions including a complete array of 22 Amino Acids, vitamins, minerals, proteins as well as some very important growth factors. They called it YTE®.

YTE® Lowers the stress response study

A double-blind, placebo-controlled study performed by Daacro GmbH & Co KG, Trier-CRO in 2009 attempted to show a possible effect of YTE in stress. This included evaluation on the cortisol level where participants were healthy male volunteers, age 20-50 years old.

Side Effects of Young Tissue Extract

Egg extracts products may cause dizziness or loose bowel movement. This side effect is part of a detoxification effect of the person taking it has severe disease or infection in the body. Some customers also experienced sleepiness for a few days, which is a known natural effect, when cortisol levels (stress hormones) decrease rapidly.

The egg extract has also been known to cause minor skin rashes and allergic rhinitis, according to a few users who may have had an egg allergy. The side effects reported are temporary. Avoid the product if you are allergic to eggs.

    You are obviously simply flogging the MLM Laminine, which doesn’t contain ANY active PESE product any more but does contain unhealthy ingredients like shark cartilage.
