There are over 100 amino acids that occur naturally, but only twenty of them are involved in making up a protein, and are classified as either non-essential or essential amino acids, so named because they can be synthesized in the body.
. These include alanine, arginine, aspartic acid, asparagine, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. Essential or indispensable amino acids cannot be synthesized in the body and can only be obtained through food. These become the rate-limiting factors for the synthesis of certain proteins in the body. The essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Before the production of the supplement known as Stemfit Active, no other companies had developed and marketed a combination of amino acids, peptides, and growth factors required to sustain robust health.
30 We looked for a balanced amino acid/peptide blend in nature, which could meet our needs with minimal additions. That is when we discovered that in 1929 a Canadian doctor, Dr. John Ralston Davison, theorized that an injected extract from fertilized hen eggs could be helpful for a number of his cancer patients. Stemfit Active In fact, he spent well over a decade developing and researching his theory. However, when Dr. Davidson passed away in 1943, his research on fertilized hen eggs quickly and quietly came to a halt and was lost. It wasn't until almost 50 years later that the pursuit of fertilized hen egg extract was revived by Norway's foremost expert on egg research, Dr. Bjodne Eskeland.
