Unlocking the Mysteries of Lutein: An In-Depth Exploration

Posted November 28, 2023

In the world of vibrant carotenoids that color fruits and vegetables with brilliant hues, there lies a hidden gem - Lutein. Predominantly found in the verdant realm of leafy greens, this powerful compound often goes unnoticed. While carotenoids like beta-carotene grab the spotlight with their striking colors, Lutein plays a vital role in maintaining the green brilliance of plants. But its significance extends far beyond that. Dr. Fred Khachik at Kemin has dedicated years to uncover the remarkable potential of Lutein, shattering the myth that it was overshadowed by its vitamin A-active counterparts. Explore the rich landscape of Lutein, from its prominence in green, leafy and yellow-orange fruits and vegetables to the exciting horizons of carotenoid research. Embark on a journey into the world of Lutein and discover why it continues to captivate our imagination, promising a bright future for human health.

What Exactly is Lutein?

Lutein belongs to a group of compounds known as carotenoids. Carotenoids are the colorful molecules responsible for the vibrant orange, deep orange, yellow-orange, and red hues in fruits and vegetables. For instance, the vivid yellow of oranges is attributed to carotenoids, while the red color of tomatoes is due to a carotenoid called lycopene.

Our bodies exhibit a remarkable selectivity in choosing which carotenoids from our food to absorb. Some of these carotenoids are active sources of vitamin A, while others lack this particular activity. For many years, carotenoids such as lutein, zeaxanthin, and lycopene were somewhat overlooked because they do not possess vitamin A activity. In fact, some scientists used to question their significance.

However, this apparent neglect prompted Kemin’s Dr. Fred Khachik’s research in the carotenoids that were often dismissed, lutein being one of them. When you examine various fruits and vegetables, you'll find that lutein is the predominant carotenoid in many green, leafy and yellow-orange fruits and vegetables, often coexisting with beta-carotene.

Current Research and the Future of Lutein

Dr. Fred Khachik’s journey with carotenoids began back in 1983, and it has been an evolving process. Initially, Dr. Khachick focused on identifying carotenoids in fruits and vegetables, a task that spanned about seven to eight years. Subsequently, his research delved into analyzing human plasma, organs, and tissues to understand which carotenoids from our diet ultimately find their way into our bodies.

This research then led to Dr. Khachik’s involvement in clinical studies. One of the early pilot studies explored the appropriate dosage of lutein for a larger clinical trial conducted by the National Eye Institute, which focused on subjects with an early stage of macular degeneration. Safety during lutein supplementation was a significant aspect of these clinical studies.

Dr. Khachik’s primary background is in organic chemistry, so another facet of his work revolves around organic synthesis. He seeks ways to create other carotenoids from compounds like lutein and zeaxanthin. These carotenoids are often rare in nature, making their synthesis an exciting endeavor, utilizing eco-friendly and sustainable methods.

Additionally, Dr. Khachik concentrates on the isolation and structure elucidation of carotenoids from nature. The bounty of carotenoids provided by nature presents intriguing health properties, and his goal is to explore beyond lutein and zeaxanthin, uncovering new carotenoids that could further enhance our well-being.

In essence, Dr. Khachik’s work encompasses the development of environmentally friendly methods for carotenoid synthesis and the characterization of these fascinating compounds found in nature.

Concluding Thoughts

Dr. Khachik’s extensive work in the world of carotenoids, particularly lutein, has opened doors to a deeper understanding of their potential benefits. As the future of lutein research unfolds, we anticipate exciting new discoveries in the realm of human health.
