It is specified to contain a minimum of 8% PRPs and it's coated with Symbiotics BIO-lipid(TM) coating to ensure peak bioavailability.

Immuliex(R) Powder comes from USDA Grade A dairies that are hormone, pesticide, antibiotics and rBST free.

Suitable for lactose-free diets.

Additional Information

Newborns who breastfeed get a head start in immunity through the PRP’s and other immune factors they get from their mother’s Colostrum. This is often called "Passive Immunity."

PRPs are extracted from bovine colostrum – dairy cows are the most abundant source of raw colostrum available today. The PRPs in bovine colostrum are the same as all other mammals and can be used as a health supplement for all other mammal species, including humans.

The potency of each PRP Powder batch is analytically validated using a HPLC/UV/MS system.

We only use the first 2 milkings to guarantee potency and quality.

Quality and Purity Guaranteed - We guarantee that this product meets the highest standards of quality, purity and freshness.
