Food for Glutathione Precursors
glutathione levels depend on the supply of three amino acids -
Glutamate, Glycine and Cystine. Glutamate and Glycine are availble
in most diets, but Cystine comes mostly from eggs, milk and cheese.

of milk and manufacture of cheese the
composition of Cystine is changed to Cysteine.

best way to increase and maintain your GSH levels is to include
these animal foods in your diet as these contain the amino acids
required by the body to synthesize GSH.
Dr. David L. Phillips, writes in Glutathione,
A Protein Vital to Life, Part 2, "supplementing with
oral glutathione won’t work. The glutathione in your cells needs
to be made by your cells. Taking GSH orally, like a vitamin, is
a waste of money. Your digestive system will break it down and
little good will come of that effort."
of hydrolysis of glutathione by intestinal and hepatic gamma-glutamyltransferase,
dietary glutathione is not a major determinant of circulating
glutathione, and it is not possible to increase circulating glutathione
to a clinically beneficial extent by the oral administration of
a single dose of glutathione. (1)
rich in the sulfur amino acids (e.g., eggs) are especially good
sources. Another excellent food supplement is undenatured (non-heated)
precursors, such as cysteine, methionine and glutamine raise
GSH levels to a minor degree, but all have side effects and are
not well tolerated by most people.
thistle, melatonin and lipoic acid can be helpful as well but
the bio-response and degrees of bioavailability can vary widely.
proteins seem to be the best method of obtaining the building
blocks of glutathione.
infants have high GSH levels and for the most part enjoy better
health until about the age of 15 until their GSH level off to
that of non-breast-fed infants. The whey content of raw milk contains
several albuminous proteins that supply potent GSH precursors."
is comprised of four major protein fractions and six minor protein
fractions. The major protein fractions in whey are beta-lactoglobulin,
alpha-lactalbumin, bovine serum albumin and immunoglobulins.
of these components have important disease-fighting effects. In
addition, whey protein is easily digestible and lactose-free.

is loaded with nutrients and essential amino acids and is of value
for those suffering from cachexia, or wasting syndrome, as its
proteins are easily assimilated by the body.
whey protein is manufactured or formulated in the

do your due diligence when choosing one that is right for you.
The one we personally use and recommend has been used
more often in clinical trials than any other whey product.
