Is Human Intrinsic Factor from humans?

Instead of sucking out the stomach juices from humans and making a 'concentrate' containing IF (which was the practice about 25 years ago), the Xeragenx technology inserts the gene for human IF into a common plant bacteria  and once inside the plant cell, transfers the human gene to the plant DNA pool. It took about 10,000 experiments by molecular biologists to do this successfully. But they did, and the result is that the plant that was 'transformed' to carry this human gene, and now, under proper growing conditions would express the protein in their leaves, roots and stems.

Bio Quick View

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.
