Bioidentical Polypeptides™

Bioidentical Polypeptides™ products are made to achieve immunological homeostasis, derived and concentrated from bovine colostrum. Unlike other immune balancing products, Bioidentical Polypeptides™ contain high levels of colostral polypeptides, also referred to in the scientific literature as proline–rich polypeptides (PRPs). PRPs are one of the most important substances in colostrum and play a significant role in helping the immune system function in homeostasis.

Oral Spray

PRO Bioidentical Polypeptides™ Oral Spray Bioidentical Polypeptides™ Oral Spray

Bioidentical Polypeptides™ Oral Spray is a liquid fraction of whole colostrum rich in PRPs. With Bioidentical Polypeptides™ Oral Spray, the PRPs and other natural immune-supporting nutrients are delivered via a unique and effective oral spray delivery system. With this system, the PRPs and other immune factors are absorbed quickly in the digestive tract because the 80+ identified low-molecular weight peptides are less than 5,000 daltons.

Bioidentical Polypeptides™ Oral Spray utilizes a proprietary patented process (US Patent No. US7,547,770B2). In the United States, it is sold as a health supplement.

LD™ Capsules

PRO Bioidentical Polypeptides-LD™ Capsules Bioidentical Polypeptides-LD™ Capsules

Bioidentical Polypeptides-LD™ Capsules is a proprietary bovine colostrum powder with enhanced PRP levels and liposomal delivery. It contains a minimum of twelve percent (12%) PRPs, which is 4–40 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 to produce Bioidentical Polypeptides-LD™ capsules. Sovereign Laboratories then uses our proprietary liposomal encapsulation technology (LD-Liposomal Delivery) to protect the delicate proteins; this allows for maximum delivery and absorption into the small intestine.

What Are Polypeptides?

Polypeptides are short chains of amino acids naturally occurring in the body and are the primary regulators of intercellular communication. These signaling peptides function as messengers in the body.

Maintaining homeostasis or balance of the immune system is vital. A healthy immune system is typically in a state of homeostasis. Bioidentical Polypeptides™ promote a healthy immune system.

Using Polypeptide Supplements

Although some specific forms of polypeptide therapy may require a prescription (i.e., pharmaceutical formulations), polypeptide supplements generally do not. For example, certain injectable polypeptide products require a physician’s prescription.

Serving size and frequency of use for polypeptide products will vary from person to person. Users should always follow the instructions on the label and avoid exceeding the recommend serving. Be patient as it may take time before users see any noticeable results. If users have milk allergies, please reconsider their use of Bioidentical Polypeptides™ supplements.

It’s also important to understand that colostrum and polypeptide products should be used as part of an overall healthy lifestyle. Certain factors, like excessive alcohol use and unhealthy eating can actually prevent users from capitalizing on the benefits of both colostrum and colostrum-derived polypeptide products.

Keep in mind that these supplements are not designed as a short-term solution. They are intended as a long-term tool to support the immune system.
