Jonathan’s background as a practicing diabetes specialist for 15 years and 17-year career developing nutritional prescriptive products for the pharmaceutical industry has contributed to his ability to understand nutrients, how they work and why they are important.
Over the years he has acquired broad and in-depth knowledge in minerals, essential fatty acids and other nutrients, but has special expertise in Vitamin B12 and choline metabolism. He is often asked to speak at national and international venues to articulate why B12, folate and choline are so important to gene function, brain development, liver and cardiovascular health. He applies pharmaceutical standards to nutrient science and has developed a unique ability to translate complicated concepts into simple promotional messages that resonate with practitioners and consumers. He has developed dozens of innovative nutritional products, of which many are category leaders in the US. Jonathan obtained his medical degree from the University of the Witwatersrand Medical School in South Africa and did his fellowship in Endocrinology at Washington University in St. Louis, MO.

There are many more people who don’t have enough B12 than we thought.
A balanced diet of B12, folate and choline is critical to ensuring the benefits of methylation (known as single carbon metabolism).
The human recombinant Intrinsic factor is extracted by sophisticated pharmaceutical grade purification methods.
The plant has become the factory for Intrinsic Factor.
No! But it is human-derived because it is produced from the gene that makes human Intrinsic Factor.
The gene for a human protein is inserted into the genetic code of other cells that can produce a protein that is identical to what is made in the body.
Intrinsic Factor (IF) is a protein made in the stomach that is essential for ensuring the natural absorption of vitamin B12.
MMA Measurement is a More Accurate Way to Evaluate Vitamin B12 Status
