Polyshield Technology™ The Power is in the Peel™

If you have been following along with us on social media, you may have noticed the excitement over the launch of Dr. D’s Vitamin D3 plus K2.

The excitement is largely surrounding the technology behind it: Polyshield TechnologyTM…The future of vitamin and mineral delivery.

Let’s take a step back to explain why this technology is so important!

Absorption & Bioavailability of Vitamins and Minerals: The Problem

Bioavailability, by definition, is the proportion of an ingested substance that is able to have a bioactive effect. Specifically, bioavailability is a product of how much a substance gets into the bloodstream, how fast it gets there, and how long it remains there.

Vitamins and minerals are readily digested and excreted – in most cases without reaching the target site in the body.  The poor bioavailability of vitamins and/or minerals can lead to deficiencies, system malfunction and disease.

Polyshield Technology™: The Solution

The name was derived since the technology involves polyphenols from the pomegranate peel creating a shield around vitamins and minerals. Allow us to explain…

What are Polyphenols?

Polyphenols are micronutrients that exist in certain plant-based foods. Studies suggest that long-term ingestion of foods rich in these micronutrients offer some protective effect against the development of chronic disease such as: cancers, cardiovascular disease, diabetes, osteoporosis and neurodegenerative disease. Polyphenols contain antioxidant, antimicrobial and anti-inflammatory properties.

Why Pomegranate?

Pomegranate fruit contains an abundance of polyphenols.

Studies show that pomegranate possesses the following powerful properties:

• Antioxidant

• Antibacterial

• Antiviral

• Anti-inflammatory

• Glucose regulation and

• Cholesterol-lowering activity

Pomegranate has also been shown to be an asset in the food industry as a natural preservative and stabilizer.

Why the Pomegranate Peel?

The peel accounts for approximately 60% of the pomegranate fruit, and possesses more antioxidant activity than its seeds, juice and pulp. The peel is a rich source of a the most important types of polyphenols in the pomegranate, called ellagitannins and punicalagin and therefore the health benefits of the fruit are attributed largely to the peel itself.

The Power is in the Peel™

Polyphenols extracted from the pomegranate peel are used in this shielding technology to protect the vitamins and minerals. The shield formed protects the core molecules and reduces interaction with enzymatic reactions involved in metabolism. Due to its optimal stability, the shield allows its nutrients to remain protected as they travel through something called First-Pass metabolism, which is breakdown by the liver. Therefore, POLYSHIELD TECHNOLOGY serves as an optimal delivery system for improved absorption of vitamins and minerals compared to current technologies.

It has been clinically proven to have:

  • Enhanced Absorption
  • Increased Stability and Potency
  • Sustained Release

Pilot Study on Dr. D’s Vitamin D3 plus K2 Absorption


To compare the blood concentration of vitamin D in subjects taking Vitamin D3 capsules (powered by Polyshield Technology™) to those taking placebo.


A placebo- controlled trial in which two groups, of three subjects each, are involved.

Group 1 received the vitamin D3 capsules of 1000-1500 IU

Group 2 received placebo


  • After an overnight fast, blood levels of Vitamin D were measured in both groups. 
  • Dr. D’s Vitamin D3 plus K2 Group (Group 1) was given the treatment capsule in the morning after food.
  • Placebo Group (Group 2) was given a placebo in the morning after food

This treatment continued for two weeks and blood samples of all six subjects were collected and

evaluated for vitamin D levels on the 7th day and again on the 14th day.

Conclusion: The study demonstrates Dr. D’s Vitamin D3 plus K2 provides enhanced absorption, increased stability and potency and sustained release.

This technology not only overcomes the problem of poor absorption of vitamins and minerals but also provides powerful antioxidants from the pomegranate peel itself! *
