BioIdentical Polypeptides-LD™ capsules is a proprietary bovine colostrum powder with enhanced PRP levels and liposomal delivery (LD). In capsules or powder form, Bioidentical Polypeptides-LD contains a minimum of 12% PRPs (proline-rich polypeptides, or low molecular weight colostral polypeptides), which is four to 40 times more than is typically present in other bulk bovine colostrum powders.

State-of-the-art and proprietary technologies are utilized to extract PRPs which are then added to first-milking bovine colostrum with liposomal delivery to produce BioIdentical Polypeptides-LD™. Sovereign Laboratories then uses our proprietary liposomal encapsulation technology to protect the delicate proteins against stomach acids, bile, and other digestive enzymes; this allows for maximum delivery and absorption into the small intestine.

How to use:

Adults take 2 capsules twice daily on an empty stomach.

Children take 1 capsule one to two times daily.

Tablets can also be taken in water if unable to swallow.
