Are Carnosine and Zinc Carnosine synthetic or natural?
While we firmly believe that natural is better, and we always endeavor to use natural-source ingredients, the natural form of many nutrients can be extracted or synthesized, with either method producing nature-identical molecules.
The synthesized form is called "nature-identical" if it has the exact same molecular and chemical structure of the substance found in nature. Some companies use the term "bio-identical" instead of "nature-identical".
Often the synthesis of nutrients in laboratories is obtained by growing benign bacterial cultures that produce nature-identical nutrients through natural fermentation. Other nutrients are very simple molecules that can be obtained utilizing basic chemical reactions, such as reacting specific starches with acids.
Some nutrients are synthesized or partially synthesized (such as Zinc Carnosine). Other examples include ascorbic acid (Vitamin C), mineral citrates, amino acids, B-vitamins like methylcobalamin, etc. The safety and efficacy of nature-identical nutrients have been proven over many years, and in many cases are identical to forms naturally synthesized in the body from food sources of their precursors or are the exact same forms that would be produced by isolating specific nutrients from food or other natural sources. Synthesized nature-identical nutrients often are of higher purity and are more cost-effective than isolated nutrients from natural material sources.
