Marcus Feldman holds a Master’s degree in Food Science and Technology and specializes in the safety assessment of food additives and processing aids. His professional background includes consulting for food manufacturers on ingredient labeling, regulatory frameworks, and formulation optimization. At Active Ingredient Hub, Marcus focuses on ingredient transparency—breaking down what sweeteners, stabilizers, colorants, and preservatives actually do in food systems. His writing is grounded in toxicology data, regulatory approvals, and real-world manufacturing practices, helping readers separate science from misinformation. When he’s not analyzing ingredient lists, Marcus enjoys urban gardening and experimenting with plant-based cooking. He’s particularly interested in clean-label trends and frequently tests alternative natural stabilizers in his own kitchen. He believes understanding food chemistry empowers consumers to make informed decisions rather than fear-driven ones.

THE BEST ANIMAL-BASED AND PLANT-BASED FOODS HIGH IN VITAMIN B12

Marcus O. Feldman, MSc

From a food scientist’s perspective, it is fascinating, and sometimes frustrating, to watch how the public conversation handles micronutrients like vitamin B12. In my consulting work with food manufacturers, ingredient transparency is everything, and B12 (or cobalamin, to look at it through a chemical lens) is a prime example of a nutrient surrounded by both […]
