Eu Yan Sang Premium Concentrated Bird's Nest can be consumed directly from the bottle chilled or warmed. It is recommended to take a spoonful either early in the morning on an empty stomach before breakfast or in the late evening before sleep for optimal absorption. Bird's Nest is the best rejuvenating supplement for people of all ages.

Bird's Nest Recipes:
 

Bird's Nest with Bulbs Lily and Lotus Seed (Serve 3 persons)

• Boil 5 qin of the lotus seed and 5 qin of bulb lily with rock sugar for 40 mins, add 3 tablespoons of bird's nest and coconut milk to the sweetened soup stir well and serve.
   

Congee with Bird's Nest

• Cook rice in the pot with twice the amount of water for 15 minutes depending on your preferred consistency. Once the rice is fully cooked add lean meat or fish to cook for another 15 minutes. Add 3 tablespoons of Eu Yan Sang Premium Concentrated Bird's Nest (Sugar-Free) and cook it in low fire for another minute. 

Bird's Nest is the nutrient-rich salivary secretion of swiftlets. This gel secretion is an integral component to building the swiftlet nests, which are found in dangerous and highly inaccessible locations like steep cliffs, overhanging crags and deep caves.

Out of more than 30 species of swiflets, only 2 species of the genus Aerodramus and 1 of the genus Collocalia make edible saliva nest. Aerodramus fuciphaga is the swiftlet that produces the highest quality of edible Bird’s Nest, because its nests are white and clean with minimum feathers. It is found only in Southeast Asia. Tedious process of cleaning approximately 10 nests takes approximately 8h by a person¹.

The major components of EBN are its glycoproteins, carbohydrates and trace elements. Scientific findings by the researchers in Chinese University of Hong Kong discovered that epidermal growth factor (EGF) is present in EBN. They demonstrated an epidermal growth factor (EGF)-like activity in aqueous extract of edible bird’s nest that stimulated the DNA synthesis in 3T3 fibroblast in a dose dependent manner in vitro². EGF is a low-MW polypeptide, which stimulates cell growth and proliferation, demonstrating properties of skin and tissue repair.

Major carbohydrates consist of sialic acid (9%), N-acetylgalactosamine (galNAc) (7.2%), N-acetylglucosamine (glcNAc) (5.3%), galactose (16.9%) and fucose (0.7%). There had been studies showing that sialic acid aids in moderating the immune system receptors, preventing entry of bacteria and viruses. The carbohydrate also benefits the brain development of infants³. The other carbohydrate components present demonstrate important roles in signal transduction in cellular communication.

The most abundant amino acids are serine, threonine, aspartic acid, glutamic acid, proline, and valine^{1, 4}.

• Aspartic acid- aids in production of immunoglobulins and antibodies, and helps fight against fatigue.
• Glutamic acid- aids in the metabolism of sugars and fatty acids.
• Proline- Improves skin texture by aiding production of collagen. It reacts with Vitamin C to form healthy connective tissue.
• Serine- aids in the production of immunoglobulins and antibodies. A natural moisturizing agent.
• Threonine- Important for the formation of collagen and elastin
• Valine- Important in muscle metabolism and tissue repair
