nuk

NUK, usually written in uppercase, is a global brand of infant feeding products, including bottles, nipples, pacifiers, and related accessories. The brand originated in Germany in the mid-20th century to meet infant feeding needs and is now sold in many countries.

Product lines typically feature orthodontic nipples designed to resemble natural breastfeeding, and bottles with anti-colic venting systems to reduce air swallowing. The range includes pacifiers and training cups, offered in multiple sizes and flow options to accommodate different stages of infancy. Materials used in markets with modern safety regulations are commonly BPA-free and tested to international standards; some products use silicone nipples and various plastics.

Market presence: NUK products are widely available through pharmacies, baby supply stores, and online retailers. They are subject to consumer safety regulations in each market, with certifications and guidelines varying by country. Care and maintenance guidance typically includes regular replacement of nipples and pacifiers, proper sterilization, and avoiding overheating in dishwashers or microwaves beyond manufacturer recommendations.

Beyond the brand, the term nuk may appear in other contexts, but the name is most widely recognized in connection with infant feeding products. The acronym may also show up in unrelated uses, depending on language and domain, but NUK remains the best-known reference in consumer terminology.
