Small Molecule Ferrous Glycinate With High Bioavailability As Iron Supplement For Soft Candy, Beverages, Solid Beverages
What is Ferrous Glycinate ?
Ferrous Glycine, molecular formula Fe(OOCCH2NH2)2·2H2O, theoretical iron content 23.3%, dark brown or gray-green powder, no iron smell, easily soluble in water, is an amino acid chelate, its unique small molecular group can pass through the digestive tract mucosa completely, so the side effects are small and the absorption rate is high.
Ferrous Glycine is an ideal iron nutrition enhancer, which is of great significance to prevent iron deficiency and improve health. It can be used in soft candy, beverages, solid beverages, oral liquids, milk powder and other industries.
Ferrous Glycine is an innovative iron supplement that combines the mineral iron with the amino acid glycine to create a highly bioavailable form of iron. This small molecule iron compound is becoming increasingly popular in the food and beverage industry for use in products such as soft candy, beverages, and solid beverages. Its high absorption rate and minimal side effects make it an ideal choice for improving iron levels in a wide range of consumer products.

Application characteristics of ferrous glycinate
1. Ferrous glycinate exists in the form of chelate, is absorbed autonomously in the body, does not interact with other foods, and is stable and effective.
2. Ferrous glycinate has a high absorption rate and can promote the absorption of elements such as calcium, iron, and selenium.
3. It can avoid the absorption barrier of phytic acid to general iron supplements.
4. It will not cause food to change color or taste.

Advantages of Ferrous Glycinate as a Source of Iron
1. High Bioavailability:
One of the main advantages of ferrous glycinate is its high bioavailability. The chelation of iron with glycinate helps the body absorb the mineral more easily, leading to higher iron uptake compared to other forms of iron. This makes it a highly efficient iron supplement, especially for individuals with iron deficiency or those at risk of anemia.
2. Gentle on the Stomach:
Traditional iron supplements, such as ferrous sulfate, often cause digestive side effects like nausea, constipation, and stomach discomfort. Ferrous glycinate is gentler on the digestive system, making it suitable for people with sensitive stomachs or those prone to gastrointestinal issues.
3. Minimal Interaction with Food:
Ferrous glycinate is less likely to interact with food components like phytates, which are known to inhibit iron absorption in the body. This makes it ideal for use in fortified foods and beverages, ensuring that the iron remains bioavailable even in the presence of other dietary inhibitors.
4. Stable and Soluble:
Ferrous glycinate is stable in a variety of formulations and is highly soluble in water, making it easy to incorporate into liquid and solid beverages, soft candy, and other food products. Its stability ensures that the iron content remains intact throughout the product’s shelf life.
5. Neutral Taste and Appearance:
Unlike some iron salts that impart a metallic taste or cause discoloration in foods and beverages, ferrous glycinate has a neutral taste and does not affect the appearance of the final product. This makes it an ideal option for food manufacturers looking to fortify their products with iron without compromising the sensory experience.

Applications of Ferrous Glycine
1. Soft Candy:
Soft candy products are an increasingly popular medium for delivering nutritional supplements, and ferrous glycine is perfectly suited for this application. The small molecular size of ferrous glycine ensures easy incorporation into candy formulations, providing consumers with a tasty and convenient way to meet their daily iron needs. Fortified soft candies can be enjoyed by children, pregnant women, and individuals who struggle to take traditional iron supplements in pill form.
2. Beverages:
Ferrous glycine is highly soluble in liquids, making it an excellent option for use in iron-fortified beverages. It can be added to fruit juices, sports drinks, and nutritional shakes without altering the taste or texture of the drink. The high bioavailability of ferrous glycine ensures that consumers receive the full benefit of the iron content, improving energy levels and overall health.
3. Solid Beverages:
In addition to liquid beverages, ferrous glycine is also suitable for solid beverage formulations such as instant drink powders and effervescent tablets. These products offer a convenient and portable way to boost iron intake. Solid beverages fortified with ferrous glycine dissolve quickly in water, providing a quick and easy iron supplement solution for busy individuals.
4. Nutritional Supplements:
Ferrous glycine is commonly used in a variety of nutritional supplements, including multivitamins, chewable tablets, and capsules. Its high bioavailability makes it a popular choice for supplement manufacturers who want to ensure their products deliver optimal health benefits. Because it is gentler on the digestive system, ferrous glycine is also an excellent option for those who experience stomach discomfort with traditional iron supplements.
