Our brand Landnutra supplies sialic acid n acetylneuraminic acid powder - a fermentation‑derived, human‑identical monosaccharide standardized to ≥98% purity that functions as a terminal sugar on glycoproteins and glycolipids, influencing cell‑cell recognition, neural development, and anti‑inflammatory pathways. This is the same Neu5Ac that dominates human milk oligosaccharides and brain gangliosides, which is why it is being adopted by formulators of infant nutrition, cognitive‑health supplements, and premium anti‑aging skincare. Every batch is produced under full cGMP using a non‑GMO microbial strain, purified through ion‑exchange chromatography, and dried to a moisture level below 0.5% before being vacuum‑packed in light‑protected foil. For R&D groups exploring new product concepts, we provide a technical dossier that includes an NMR‑verified structure report, a residual‑endotoxin certificate (routinely <0.05 EU/mg), and a forced‑degradation study that maps pH and temperature boundaries - data that helps you move from concept to pilot batch without commissioning external stability work.

Benefits Of sialic acid n acetylneuraminic acid powder
01 Brain Development & Cognitive Function
Sialic acid forms key brain gangliosides. It aids synapse growth and learning, ideal for infant nutrition and kids' cognitive supplements.
02 Immune Modulation & Gut Health
Neu5Ac serves as a pathogen decoy on mucosa, blocks bacterial attachment and balances gut immunity, suitable for gut-brain axis formulations.
03 Skin Hydration & Anti‑Glycation
For cosmetics, it strengthens skin glycocalyx, locks moisture and inhibits glycation, boosting elasticity and diminishing fine lines in anti-aging & beauty supplements.
04 Human‑Identical, Low Immunogenic Risk
Our Neu5Ac matches human endogenous structure, without sensitisation risks, safe for long-term oral/topical use for infants and seniors.
05 Fermentation‑Derived, Animal‑Free
Produced via non-GMO microbial fermentation with plant feedstock. Vegan, Halal & Kosher, meets global clean label standards, no bird's nest or animal sources.
06 Customisation & Regulatory Support
Custom particle sizes and pre-blends with DHA, probiotics, collagen. Complete test documents accelerate global product registration.
Application Fields
• Infant Formula & Follow‑on Foods: Simulates human milk sialic acid to support neural and immune development.
• Dietary Supplements: Memory capsules, kids' brain powders and anti‑aging formulations.
• Functional Beverages: Cognitive shots, beauty drinks and focus‑support tonics.
• Cosmetics & Personal Care: Hydrating, anti‑glycation skincare serums, creams and masks.
• Clinical & Medical Nutrition: Enteral formulas for neuro and immune nutritional support.
• Pet Supplements: Cognitive support chews for senior dogs and cats.
