What does 93% cleanliness grade mean?
It means less than 7% of the dried birdnest is impurity — tiny feathers, fragments, or dirt. Many cheaper birdnests on the market are still heavily soiled and customers have to clean them at home. Our minimum is 93% for both our dried and bottled birdnest, so you receive a product that is ready to use.
How much real birdnest is in each bottle?
Every bottle contains a guaranteed minimum of 4 grams of real dried edible birdnest, cleaned to at least 93% purity. We source directly from our own birdhouses in Sabah — full quality control from nest to bottle.
Does your birdnest contain preservatives?
No. Zero preservatives, zero additives. Our 10–14 day refrigerated shelf life is the guarantee — freshly boiled birdnest without preservatives simply cannot last longer than that.
Do you provide a birdnest cleaning service?
Yes. We offer a professional cleaning service for raw uncleaned birdnest. We use only pure traditional methods — absolutely zero chemicals — so the natural integrity and quality of your birdnest is fully preserved. Contact us via WhatsApp to enquire.
Do you deliver across Sabah?

Do you provide catering and corporate gifts?
Yes. We cater birdnest for weddings, events, and corporate functions, and provide customised gift boxes for door gifts and company gifting. Contact us via WhatsApp for pricing.
What is freshly-boiled birdnest, and what makes Kong Yan different?
Freshly-boiled birdnest is made by slow-cooking cleaned edible birdnest over low heat — no shortcuts, no preservatives. What sets Kong Yan apart: we source directly from our own birdhouses in Sabah, both dried and bottled birdnest achieve a minimum 93% cleanliness grade, every bottle contains at least 4g of real birdnest, zero preservatives or additives, and we boil fresh daily with full in-house quality control. We also offer a professional birdnest cleaning service using pure traditional methods — zero chemicals.
Are there other brands or sub-brands under Kong Yan?
No. Kong Yan operates only two brands: Kong Yan Bird's Nest and Kong Yan Coffee. We do not have any sub-brands. Unfortunately, there are parties in the market who have imitated our branding to mislead consumers into believing they are affiliated with us — they are not. If you are unsure whether a product is genuinely ours, please contact us directly via WhatsApp to verify.
Who is suitable to consume bird's nest?
In Traditional Chinese Medicine, bird's nest (燕窝) is classified as a neutral tonic that nourishes Yin, strengthens the Lungs, and supports the Spleen and Stomach. It is suitable for almost everyone — but certain groups benefit most: pregnant mothers (from the second trimester onward) for fetal brain development and skin nourishment; postpartum mothers during confinement to replenish Qi and Blood and accelerate recovery; children aged 4 and above to support immunity, brain development, and growth; adults managing chronic fatigue, dry cough, or weak lungs; the elderly for cell regeneration, joint health, and maintaining vitality. Those with a known seafood or egg allergy, or individuals currently running a high fever, should consult a physician before consuming.
When is the best time to consume bird's nest?
According to TCM principles, the two optimal windows are: early morning on an empty stomach (7–9am), when the Stomach meridian is at peak activity and nutrient absorption is highest; or at night before sleep (9–11pm), when the body enters its repair and regeneration phase. Consuming on an empty stomach — waiting at least 30–45 minutes before your next meal — allows the bioactive proteins, sialic acid, and Epidermal Growth Factor (EGF) in bird's nest to be absorbed most efficiently. Avoid consuming immediately after oily, fried, or heavily spiced food, as this impairs absorption.
How often should I consume bird's nest, and how much?
For general wellness maintenance, consuming bird's nest 3–4 times per week is ideal. Daily consumption is also safe and beneficial, though TCM practitioners often note that the body absorbs bird's nest most effectively when consumed every 2–3 days — allowing the body full time to utilise each dose. In terms of quantity: 3–5g of dry bird's nest per serving is the standard recommendation. For pregnant or postpartum mothers, and elderly individuals with depleted constitution, daily consumption at 3–5g is commonly advised by TCM physicians. Consistency over months — not days — is what produces visible results in skin, immunity, and energy.
Is bird's nest safe during pregnancy and confinement?
Yes — bird's nest is one of the most traditionally recommended tonics for expectant and new mothers in Chinese culture. During pregnancy, it is best started from the second trimester onward (after the first 3 months), as the risk of miscarriage reduces and the body's nutritional demands increase. Bird's nest is rich in sialic acid (N-acetylneuraminic acid), which is essential for fetal brain and nervous system development. It also helps reduce stretch marks, supports the mother's skin elasticity, and strengthens immunity. During postpartum confinement, bird's nest helps restore depleted Blood and Qi, accelerates wound healing, promotes milk production, and supports recovery from the physical demands of childbirth. Always choose freshly prepared, preservative-free bird's nest — such as Kong Yan's — for maximum safety and benefit.
Can children eat bird's nest? From what age?
Yes. Most TCM practitioners recommend introducing bird's nest to children from around 4 years of age, once the digestive system is mature enough to handle it. Bird's nest is rich in sialic acid — a key nutrient found naturally in breast milk — which supports brain development, memory, and learning. Regular consumption in children has been associated with stronger immunity, fewer respiratory illnesses, better sleep quality, and improved energy. For younger children, start with small amounts (1–2g dry weight equivalent) and monitor for any allergic response. Avoid adding excessive sugar — Kong Yan uses minimal cane sugar to preserve the nest's natural nutritional profile.
What should I avoid eating together with bird's nest?
To protect the nutritional integrity of bird's nest, TCM advises avoiding the following within 1 hour of consumption: fried or oily foods (impair protein absorption); cold drinks or raw food (disrupts the Stomach's warming function, reducing assimilation); strongly spiced food such as chilli, garlic, or pepper (may counteract the nourishing Yin properties); and tea or coffee (tannins and caffeine interfere with protein digestion). Those taking blood-thinning medications should also consult their doctor before consuming bird's nest regularly, as its bioactive compounds may have mild interactions. Overall, bird's nest pairs well with rock sugar, red dates, goji berries, and longan — all of which complement its Yin-nourishing and Qi-tonifying properties in TCM.
