Colostrum & our Bio-Active Protein Comparison

Cystine is essential to the immune system.  But, the proteins in colostrum have almost no cystine content.  In addition, research published by one manufacturer of colostrum, in The Vital Health News, Winter 1998 edition, page 7, demonstrated that "the effectiveness of the immune factors present in colostrum is lowered by stomach acid."  Colostrum, which is produced during the first 26 hours following birth by the mammary glands, is primarily composed of immunoglobulin and some lactoferrin.  According to both laboratory experiments and clinical trials conducted in Germany, colostrum supplementation was associated with mild increases in immune function in some patients, but these increases were not statistically significant (p=ns).    Since the primary mechanism of action on the immune system is through stimulation of the production of glutathione, the near absence of glutathione precursors in the immunoglobulin fraction  of colostrum may explain its relative lack of efficiency.  Our bio-active protein contains substantial amounts of alpha lactalbumin, lactoferrin and serum albumin, which contain high levels of cystine residues.  According to the US Physician's Desk Reference, cystine is the preferred form of cysteine for the synthesis of glutathione in macrophages and astrocytes.   This allows these cells to provide cysteine to lymphocytes and neurons directly upon demand.
