FAQ
NEM® is a nutritional ingredient extracted from the inner membrane layer of fresh eggs using exclusive patented separation and drying technology, containing standardized hyaluronic acid, chondroitin, and collagen.
NEM® is a patented extract of the inner membrane layer with standardized ingredient quantification and extensive clinical research supporting its efficacy, unlike general powders made by simply grinding eggshells.
Its core indicator components include hyaluronic acid, chondroitin, and collagen, forming a standardized structural matrix.
According to clinical research, improvements in joint pain and stiffness can be observed after 10 days of continuous use.
This means NEM® repurposes byproducts from the food production process into high-quality nutritional ingredients, offering environmental and sustainable value.
NEM® is highly suitable for athletes and outdoor enthusiasts, adults focused on daily nutritional quality, and seniors seeking functional ingredients.
The ingredient has passed GMP, Halal, and Kosher certifications, complying with strict food-grade supply chain management.
Yes, it is derived from the natural inner membrane layer of eggs and is a Clean Label natural nutritional source.
It is recommended to store the products in a cool, dry place and avoid exposure to high temperatures and humidity.
Because it uses patented technology to transform egg byproducts from the food industry into high-value ingredients, earning the Upcycled Certified status in line with modern sustainability trends.
